LayR – Multi Timbral Synthesizer

LayR – Multi Timbral Synthesizer is developed by Living Memory Software‘

Available from iTunes App Store

LayR is described as a “massively polyphonic, Multi Timbral Synthesizer” capable of up to 256 voices of multi layered and textured sounds for 64 bit devices. I was a little skeptical initially and expected less. I was wrong. LayR can actually do as it says it can.

Andy Bull created LayR somewhat by accident. He started out with something else in mind, not looking to create a synthesizer. After experiencing some disappointments with some of his iOS synths in a live stage setting, he ended up making something to meet his needs as a live performer. LayR was born, and here we are today able to enjoy the fruits of his labor. So much juicy goodness.


LayR launches with a clean, albeit dark, interface showing the general mix functions of whatever layers make up the selected patch or “performance”, as they are called. A performance is a collection of instruments which contain layers of synths. One performance can be as simple or as complicated as desired. The overall results can be astonishing, with layers coming and going in various states and times. There are a lot of excellent presets available that demonstrate the many possibilities and can be great templates to dissect and learn from. Overall it’s an exciting synthesizer that will satisfy.


Each layer is its own independent synth with 2 oscillators, each with their own shape and phase states that can be morphed, modulated and filtered. There are 2 ADSRs which can be looped from super fast out to 100 seconds, along with a 3rd ADSR controlling the overall volume. Both of the filters (LP, HP, Band & Notch) can be smoothed with a handy mini filter mixer. The 2 LFOs are well behaved and have several shapes to choose from. At first glance it all seems like a standard twin oscillator synthesizer, but that’s forgetting to consider the amazing depth of what can be hundreds of layers playing together in a giant cooperative audio party. You could easily spend days constructing elaborate performances. Pack a lunch.


It’s hard to explain just how much detail LayR is able to control better than the above screen shot. As you can see this is thoughtfully designed with a forward looking layer parameter linking tool. This will be indispensable when one gets ambitious, getting deep into greater numbers of layers with parameters that will likely need to be linked, and really helps with keeping the intended order together without needing to try and remember what was where or having to constantly switch back and forth to make sure certain layers have the same behaviors. Just link them in sets of parameter groups. My inner synth nerd did backflips when I first discovered this clever tool. You can also copy and paste one parameter to another.

The 16 step multi channel arpeggiator is quite robust. This screenshot (above) should convey how carefully it was designed to give the user a rich midi routing capability that works reliably. Up to 8 event tracks can be set up with their own synth layer, making for some very lively compositions. While getting acquainted with LayR I found some presets that were impressive and inspiring. Some had multiple synths of varied arp events, all playing together with the touch of a single key. Event notes are visible by the flash of the corresponding key as played by the arpeggiator assignments.

The in-app help can be accessed at any time should there be a need, so even someone new to multi channel arpeggiators can learn to create their own routes for their project with a minimal learning curve.


Getting back to the graphical interface, its design uses symbols relevant to each parameter control. Most experienced synth users should understand what they mean but it might also be a little unfamiliar to others more accustomed with text identifiers. Those not used to this will become best friends with the top right corner info button within the first hours. Eventually it becomes second nature. The scale and key can be set, as well as an option for a colorful keyboard if all black isn’t desired. The keyboard can be adjusted in size, range, scrolled or locked.

LayR has 3 sound effects; Reverb, Delay and a 3 Band EQ. The FX are competent and useful but not particularly noteworthy.

Inter-app audio and Audiobus are supported, but not AU. I feel like the lack of AU support is for a good reason. Might be because the current iOS AU systems can’t quite keep up yet with something so intensive as LayR. Perhaps that will change in the future?

I spent several days digging into LayR and found it to be a wonderful experience. Great sound, nice quality filters, excellent morphing and an overall magnificent synthesizer. It truly excels when put to the test of making many layers of timbres, multi channel arpeggios and wildly evolving soundscapes. LayR is no slouch by any means and should fit in everybody’s collection.

I highly recommend LayR. Be sure to check out the developers Website for a more specific feature list and links to helpful tutorial videos.

Massive Update April 20 2018 V 1.2

Audio Unit: LayR now includes a fully functional audio unit version with a dynamic user interface that adapts to the available screen space.
PDF Manual: The old help system is replaced by a comprehensive manual which can be read in-app or exported to your preferred PDF reader.
Improved User Interface: The entire UI has been given a modern facelift including pinch to zoom, double tap to zoom and fully labelled controls in the Layer Editor.
Instrument Mixer Drag & Drop: Instrument and Layer strips can now be re-arranged in the Instrument Mixer. Layers can be converted to new Instruments or copied between instruments with drag and drop.
MIDI Controller Mixer: A new panel that sports optional sliders for Channel Volumes and every MIDI cc that’s been assigned to the current performance. Allows users to perform live MIDI controller mixing in-app. Can also be used to query which parameters have been assigned to MIDI and in which Instrument/Layer they are located.
Arpeggio Sequencer: The arpeggiator gets a more descriptive name and some cool additions including new event types, new playback modes and the ability to set mode, speed and length per track.
Modulation Matrix: Modulation sources in the Layer Editor can now be routed to any destination.
Improved Oscillator: The oscillator gets Coarse/Fine tuning and “Fixed Mode” which decouples the oscillator from the MIDI keyboard. Also FM has been greatly improved with a new mode allowing modulation over the full audio range.
LFO Sync Mode: Keeps LFOs in all playing voices synced to the same phase as each other.
Wave Folder Pitch Adjust: The amount of folding is now reduced as notes get higher, this helps reduce aliasing artifacts that may be introduced by the folder when processing high frequency content.
Legacy Mode: A experimental option that keeps LayR’s engine to a fixed lower CPU usage, this will hopefully extend LayR’s lifetime for users with older, lower powered iOS devices.
Light Colour Scheme: An optional lighter colour scheme for use in bright daylight conditions.
2nd MIDI Input Port: For stand-alone app: A port which listens on all channels for MIDI Bank Select/Program messages, this port can be used to select Performance presets while allowing the other input port to use all 16 channels for multi-timbral use.
New Presets: A whole new bank of 36 presets by Sky Runner and another new bank dedicated to individual user presets.

 

PPG Infinite – Review

Developed by Wolfgang Palm

Available in iTunes App Store

Wolfgang Palm changed the world of synthesizers with the development of wavetable synthesis in the 1970s. Since then he has been responsible for numerous innovations, contributing greatly to the world of synths. Recently he brought his inventions to iOS with a collection PPG apps that have given inspiration and previously unavailable options to many artists, myself included. PPG Infinite goes in a direction that offers massive freedom with intricate sound designing, taking notes from nature by manipulating harmonic and inharmonic frequencies not found in typical synthesizers. 


For about three weeks I have explored and experimented with Infinite, and each time discovered new tonal realms. You might think by looking at the GUI that there’s not much to it. You’d be very wrong. It is simply laid out in a way that shouldn’t intimidate, but also has countless doors to open; leading to more doors and so on. Before you know it you’re reading the various “Help” articles, learning new ways to make something interesting. Just about any sound is possible. Any complaints I’ve seen have essentially been because of operator error or plain old laziness. 

What makes PPG Infinite so special is its ultra deep editing and morphing options. I don’t want to get all “tutorial” about it but to put it simply you can edit individual wave partials by the hundreds. This can lead to many different tones coming and going with their independent frequencies and envelopes while holding one key. A truly infinite audio adventure. Maybe it starts out as a stab that fades out as a drone comes in, then soon after a melody starts repeating with background ambience of any number of various sweeps or random chimes clinking about. You could rather easily have a single patch that sounds like multitrack recordings.


It’s all in how much the user chooses to spend their time in the many mod routing and parameter adjustments as they behave with the noise, morpher, and spectral filtering molders. The two Sine editors have different impacts on the sounds. Sine 1 is where you can create and edit your Sine values as they track in the waveform. Sine 2 is where the structure of the sine 1 volume or amplitudes for each partial is adjusted. All with a detailed wave graphic showing you what’s happening to your sound in real time. Additionally there is a Random panel that allows you to make changes to each sinusoids 6 parameters changing their intensity etc. Hit the “Go” button after making some adjustments and that new overtone variation is set. Adjust and repeat while being careful to save the changes. The in app “Help” does a far better job of explaining how each of these work. I recommend reading as many of these articles as you can. 


With so many editable pieces it’s not hard to get lost. Fortunately you can always revert to the original saved version of your patch and compare it to your new edits with the A B button. There is also parameter copy and paste which will become very useful, especially when you want certain partials to have the same behaviors. 

PPG Infinite’s deep mod matrix, 4 LFOs with 4 common waveforms, envelopes, filtering, morphing, molding and all the highly detailed overtone editing can have a nice delay, reverb or distortion effects added. Want more? You can also import wavetables from PPG WaveTable, and WaveMapper or phonic utterances from PPG Phonem to the Molder to expand even further upon the already massive library of included sound sources. I might add that the Molder being so versatile does make for some seriously wild filtering type effects depending on what source is selected. It’s another incredibly powerful unit that shouldn’t be overlooked.


There’s so much good stuff in PPG Infinite that I can’t cover it all. It’s no lightweight. Be patient and if you think something doesn’t work or can’t be done, take the time to read up on the in app “Help” articles or try contacting support. It can seem a bit complicated at first for some people, but in all likelihood there is a way to do what you want. 

My only complaints are a little minor. First is that the mod matrix is tiny. If there is a way to blow it up, I can’t find it-please correct me if I’m wrong. 

My other complaint is that I’ve experienced some crashes on my freshly restarted iPad Air 2 and no background apps. That is likely something that will be corrected in the near future, and I wouldn’t consider it a deal breaker since this is a very new app. Lastly, (another thing that’s hardly a deal breaker and has no impact on my overall enjoyment and satisfaction) I’ve never been a fan of how PPG’s preset managers are laid out. Other than that PPG Infinite is a marvel. It’s so nice to see something that isn’t another classic hardware reproduction. Infinite brings something new and powerful to this summer’s table of great new synthesizers for iOS.  Don’t miss this one.

KASPAR – Review

KASPAR is developed by Yonac

Available from iTunes App Store

KASPAR (resisting obvious children’s cartoon references) launches with a fierce dragon logo before quickly revealing the synthesizer and all its glory. It is an immediate impression that perhaps intentionally conveys to the user that they just released a majestic, mythical beast. This is however no myth.

In order to properly control such power a proper cage is needed to house it. What I’m saying is don’t expect to fully enjoy KASPAR on anything older than an iPad Air. The developer has included this warning in the App Store description. Somehow a couple ding dongs still wrote bad reviews because this powerful new synthesizer doesn’t work well on their old iPad 4s. Who’s fault is that? Come on. There is a very fair warning upfront that they ignored. Makes as much sense as complaining to the makers of a gold fish bowl that their product sucks because they can’t fit their pet shark in it. I’ll detail the recommendations a little more at the end of this review.


KASPAR is a massive synthesizer or really 8 synths in one with 4 touch controlled morphing (or Auto) groups. Each synth has 3 oscillators (totaling up to 24) with multiple waveforms. Dedicated filter envelopes, an arpeggiator, chord maker, 6 dedicated mods slots with 20 possible targets, 2 LFOs and more. With a strong morphing capability, loads of high quality sound effects, there doesn’t seem to be any limits to what you can come up with.

The 4 group morphing unit is controlled by touch and KASPAR can record your own custom morphing shapes that you draw. Each of the groups are x and y controls. The morpher allows for deep sound modulation control with an endless pallet of possibilities, shapes and sizes. Reassign synths easily to any group, control the x and y curve speeds and enjoy manually shaping your sound or set to “Auto” and watch it go on and morph whatever mode(6) and loop(4) type you choose.


In KASPAR it’s all bout layering. So of course there is a screen to make general adjustments to each of the 8 synths, volume, pan, and both FX bus levels. Similar to a standard mixer.


Choose from about 300 presets. Better yet, make your own synth patches from a variety of common and several unique waveforms for each of the 3 oscillators. All have pulse width/ timbre controls, and oscillators 2 & 3 also have ring modulation. The overall combined sound can have noise added with a wide tone control, and a glide option. Play polyphonic or mono with legato on or off. Pretty standard stuff. It’s the variety of unique waveforms that can spice things up. There are some interesting shapes to choose from and they can make serious impact on the sound that synth makes.


As you edit each layer of synths you will find a nice selection of independent filters to enable. All have their own unique qualities. The Fat 70’s, Formant and Comb are very cool. Mix and match your favorites or whatever your final patch design needs. They are all excellent. I couldn’t find anything lacking with the filters. I just wish I could copy a filter setting to use in a different synth layer. Come to think of it, that would be nice to have for the oscillators or other parameters as well.


Each synth has its own set of 2 LFOs and an envelope. Each LFO has 7 possible waveforms. On the Mod page (not shown) you can have up to 6 different modifiers for each synth with 20 possible sources. For a single synth having just 6 mods, might seem like it’s not much, but remember we can make up to 8 layers of 6 each. That means there are up to 48 possible mods throughout the layers. It adds up and doesn’t pose any significant limitation.


The 2 FX busses can both have up to 8 effects units selected. The signal flow is easily adjusted by touch, drag and drop. For those not familiar how busses work, it means you are sending a chain of FX to the overall sound, not inserted to each specific synth. However each synth has bus controls to adjust how much of each busses chain of FX are applied to them. It would be interesting to see what it would be like to have independent FX chains, varying units and parameters for each synth someday. I don’t think even the latest iPad Pro could handle that today? That said 2 busses are nothing to shrug off. The FX units are all high end and custom made for KASPAR. There’s plenty of interesting options and combinations.


Being a stand alone synthesizer, KASPAR wouldn’t be complete without its own recorder. It can also be used to play a imported loop along with whatever sound the app is making.

With such an enormous range KASPAR doesn’t just stop here. Each synth also has its own multi mode arpeggiator and chord maker. Program your own chords to a single key in a snap. That’s become more useful than I had thought it would.

Put it all together and you have one colossal or “super synth”. Even my iPad Air 2 performed well with heavy loads of layers, FX, arps, filters and morphs running with the “Best” audio generation quality at 256 buffer through Inter-App Audio in Cubasis. Yonac really did a good job with efficiency here. They also thoughtfully made sure to include full MIDI services, Audiobus, Abelton Link, and AU plug in.

KASPAR sports up to 12 polyphony (tested with 8), a pleasant interface with after touch and velocity controls. A very playable synth that unlocks layered sounds not seen on iOS until now. It is making summer of 2017 one of the best for synth lovers.

As I mentioned near the beginning of this review here are more device recommendations for this super synth. You should have an iPad Air, iPad Pro, iPad Mini 2 or newer. If you must try KASPAR on an older device like an iPad 4 and are willing to take the risk and not blame the developer, you might have decent results if you turn the buffer to 512 and the audio generation quality to its lowest or “Good” setting. Just know that you probably won’t always be able to use all 8 synths, mods, FX, arps etc.

Mood – How to Analog Right

Mood is developed by apeSoft

Available in iTunes App Store

apeSoft continues their offerings of reimagined classics ( i.e. iVCS 3) with Mood. A “personal interpretation” of the Analog Synthesizer by Eugenio Giordani. As apeSoft fans would expect, Mood is a faithful sonic reproduction with several modern additions that make it more than just another virtual analog synth. 


More than just another 3 oscillator VA Synth, ( is there an echo in here?) Mood comes packed with loads of user customizable widgets and supports, like an easy to use sampler, audio unit v3, full midi, Inter-App Audio, Audiobus 3, and so much more. 

This mono or up to 16 voice polyphonic synth does deliver quality at all levels of design and sonic exploration.  With the built in sampler you’ll have many more avenues of sound designing to explore. Dig in to micro details by assigning various widgets to nearly any parameter by a double tap on the knob. I’ve been up very late obsessively tweeking many different things. 

As shown above the aforementioned double tap on a parameters knob brings up the widgets screen to make those specific adjustments. It can get a bit tedious for those not interested in audio designing, but for those who are, it is very welcome. These should look familiar to anybody who has used any other apeSoft offering.  The widgets bring audio designers a mass of possibilities that can lead to some extreme detail in their sound creations. 

With the sampler you are open to many more options in possible sound designs. This is another example of how Mood separates itself from the usual or hum drum typicality of common VA synths. Import samples or record new ones from the environment or people around you. Mix and match with the FM or Wave unit, various effects, sub oscillator sounds, filters or LFOs etc. There’s not much limiting your imagination being brought to audible life. 

Although not shown in this review, there is a full service arp available. It’s accessed a little awkwardly by turning the XLFO wave knob to the lowest right hand wave form. I’m sure there’s a good reason for this, but it struck me as a bit oddly placed. Nevertheless, it is there. It’s possible I’ve had a major lapse of understanding from one too many late nights micro managing some sound I was working on. 

Moods effects are top notch. The Reverb unit has a vintage or distinctly different modern settings option and sounds very clean. That is until the powerful and grungy Distortion unit is enabled. There’s an excellent Ring Modulator for adding some unique tonal qualities. Of course a very nice Delay effects as well. 

I should mention the filters. The well designed Moog-like filters are as good as any can get for iOS. Personally I think they may be the best so far, but that’s just me. 

Overall Mood is not your ordinary virtual analog synth trying to be a perfect copy of a classic. It’s a loaded baked potato with double the flavor and satisfaction. Is it perfect? Maybe not, but what is? It’s about as perfect as I think it can be minus a few minor UI issues. Its very stable (using iPad Air 2 for this review) and with a quick buffer, it’s largely lag-free. Except for maybe a loaded 16 voice sound with heavy Reverb,  running through audiobus to a DAW with an effects unit in the chain, this synth rarely causes any grumbles or crashes. It’s hard to find any reason to no recommend Mood highly. 

Music Studio 2 Review – Tried and True

Music Studio is developed by Alexander Gross of Xewton

Available in iTunes for Apple devices, and Now GooglePlay for Android


Music Studio has been with us (on iOS) for years. It was one of the very first studio type music apps I ever bought way back when I had my iPod Touch 3G. It has seen steady and consistent updates keeping it on the level with our rapidly growing music needs. Now it’s even available for Android users in the GooglePlay store. I haven’t tried it on an Android, and honestly can’t comment about that version, but expect it works just as well.

This all in one music production suite is packed with everything you need to create music from start to finish. Over a hundred tracks sequencing, sampler, twin keyboards, custom drum & chord pads, 10 effects units, note editor, Automation, Audiobus In & Out, Inter-App Audio In and Out, MIDI, 100 Drum Loops…and more and more.


There is a free, lite version to dip your toes into if you’re not sure about buying straight away. The first thing I noticed was the quality and variety of instruments. Hundreds of studio recorded instruments come packed in with the purchase of the app, and dozens more can be purchased. Every relevant instrument is available, minus only a very few. Whatever might be missing shouldn’t be an issue these days with all the other music apps around filling nearly every gap. With MIDI, Audiobus and Inter-App Audio input/output fully supported, you’re only limited by you’re own collections of samples and instrument apps. This was the first production app I could find a Digerydoo that sounded good.


The twin keyboards can have their own instrument assigned and played. The bank of customizable chord buttons above reflect what’s being used as per your own preferences. Assigning individual percussion instruments or samples to the drum pads can also be used. Trigger and loop away, or record a sample with your device or external microphone and apply to one of the pads to use in your composition. It’s easy stuff.


Some might wonder where the mixer is? Simply put, it’s not here in the traditional sense. However every track can be mixed individually. Instead of a mixer page, just select the track to adjust the pan, level, effects, mute or solo etc. It can be a little bit of a challenge to get used to if you are more accustomed to a dedicated mixer board page, but the bottom line is, nothing’s really missing. It’s just being done differently. Most people aren’t going to be overly concerned with this unless they start piling on several dozens of tracks. Then the missing mixer just might prove to be a bit of a obstacle.

It’s never bothered me, and on the plus side a mixer page is indeed being developed for Music Studio 3. I have confirmed this directly with the developer.

Editing a tracks sequence, or sample is quick and easy. Just double tap the area within the track to bring up either the sampler page or the sequencer note editor page. Quantize, transpose, write, copy and all of that stuff should feel as familiar as it looks. Working with automated FX work much the same way. It’s a very straight forward work flow. This is very intuitive and has a very gentle learning curve. Nothing clunky or unnecessarily complicated. Smooth.


Moving on.

Music Studio 2 also has 10 built in effects units. They have improved over the years and you can assign as sends, inserts or use globally in multiples. As I mentioned above there’s automation. So making creative effects that move with the music are at your finger tips, just like any respectable studio type. All the audio effects mainstays are accounted for. Reverb, Delay, Phaser, Stereo Widener, Filter and so on. I find the EQ a little in the lite side being a simple 3 band, but that’s not much of an issue these days with Audiobus and Inter-App Audio providing such easy access to your other apps that are more specialized. What is available gets the job done and doesn’t sound cheap.


Music Studio is known for its excellent MIDI support. Whether you use virtual MIDI with other music apps, or hardware Music Studio keeps up and makes things easy on you. Reliable is the word.

There are so many great things to bring up, I can’t cover every detail. If you need more specifics, details or exact numbers just visit Xewtons Web Site. You’ll find more than just specs. There’s a thriving user community forum to help answer questions, get support or just share. Assuming the extensive in app help doesn’t put you back on track. No pun intended.

In conclusion, Music Studio stands confidently with other iDAWs, is priced very well, has better instruments than others, is a stable, quality production app with tons of tools and all delivered with a pleasantly clean interface. It’s great for those just starting out and won’t overwhelm newcomers and pros will like its longevity. It has been reliably developed with excellent consistency by a developer who is listening to his users wants and needs. Despite no separate mixer, all the same parameters can still be adjusted and mixed without skipping a beat. Few limitations and loads of options, Music Studio 2 remains an excellent choice for everybody.
