FACChorus – Review

FACChorus by: Frederic Corvest 

Available in the iTunes App Store


FACChorus (Fred Anton Corvest) is a stand alone, versatile Chorus effects app designed to emulate classic physical modules of day’s past. Not unlike the analog Roland Juno Chorus effects (and others) from decades ago. 


FACChorus sports a simple and clean interface resembling a rack mount style with realistic, responsive knobs. The no fuss look may seem a bit dated to some, but fits right in all the same. It mirrors the actual signal path from left to right (input to output) making it quite intuitive. Not that there could really be much to confuse anyone, anyway. Plus, who cares about looks when what really matters it how it sounds.


So how does it sound? Well, it sounds really good, even through an iPads built in mic. Of course better with a plug in mic, USB or in a AU (Audio Unit) setting.  This Chorus unit has a wide range of possible effects from clean and subtle to clinically insane. Most iOS synths and iDAWs have a built in Chorus but lack any real versatility and often even with the most subtle settings, sound overly wobbly. FACChorus can be manipulated to suit any need for vocals, guitars, and of course iOS instruments. Lush, rich and wide. Spacey or water logged, FACChorus gets you there. 

The properly named presets offer a nice range of ready to go effect parameters suitable for most situations.  Sadly there’s not any way to save user presets. Nor does it save your last state when the app is closed and reopened. This could be problematic for some users. 

While this great sounding effects unit supports Audio Unit V3, it does not support Inter-App Audio or Audiobus. Considering that most iDAWs (like Cubasis and GarageBand Mobile) support UA V3, this may not be much of a problem. However a lot of users have a workflow that depends on their use of IAA or Audiobus, and missing those supports could be a crucial turn off. Even though AU V3 basically works the same way as IAA. 

It’s early still, so it remains possible that more workflow supports or features might be part of future development. 

That all said, for three bucks you get an incredible sounding Chorus unit that would’ve cost far more in the physical world. 

Convoluted Spectral Filtering

3 Incredible special effects apps combine to astound us!

Big tough words right? Well, I’m serious. I’ve had some time to really sit and dig in to 3 relatively new effects apps from 3 of my favorite developers. Time enough to discover that there’s not enough time to discover it all.
Individually, each is simply marvelous in their own right, but combine them and you have a massively exciting audio trilogy of sound effects goodness.

These incredible effects apps each have uniquely outstanding qualities that by themselves would be fantastically satisfying and hugely time consuming.
Plenty of joy will come from each one, offering loads of creative experiences.

It’s when they are placed together, working in harmony through Audiobus, that they stand together like a trio of god-like rock star band mates ruling the heavens of audio special effects. Special effects gone totally bananas.
Choose your Input > Effects > route and run them all into your favorite iDAW (or Output) app to capture the sonic sundae.
Typically I use AltiSpace in the middle, between aprFilter and then csSpectral, however this combo is not only excellent but also demanding on your device. I’d not recommend anything less than iPad 4 and preferably iPad Air. Depending on your device and needs, 512 latency should be fine.

I load up my sample with apeFilter and make initial filtering adjustments. apeFilter has excellent sample and frequency control both backward and forward which can be manipulated in real time, any time.
The interactive GUI is perfect for controlling up to 36 peaks filters frequencies. Packed with high quality common filters (Lo/Hi and band pass, notch, and Hi or Lo shelf) and some post effects like delay and compression apeFilter is perfect for shaping your samples.

Don’t forget the spectral grid where you can finger paint your way through the pitch space using the 4 compilers. Try it out and you’ll see.

Next I have AltiSpace Convolution Reverb in the effects part of the chain. This is the first stand alone convolution reverb unit for iOS. In case you’re wondering what a convolution reverb is, it is a form of reconstructing the reverb effect of other reverb effects units. Taken from actual impulse response recordings or real world acoustical reverberations emulated digitally. It’s a lot of complicated math I won’t pretend to understand, it’s just really good. AltiSpace recreates some of the best reverb units made.

Something you might notice that’s very different from algorithmic reverbs is the convolution reverb doesn’t have all those parameter controls you might be used to. Controls like tail, width, and swirl etc. Instead of tweaking various parameters, you just select a different IR or impulse response. With 250 loaded IRs there’s no shortage. Plus you still have basic parameter controls including some EQing and a super cool reverse option. I love the reverse part.

In the last or output spot I use csSpectral. A Csound based multi effect processor. This thing is amazing. Nearly every parameter of each effects unit can be randomized and automated. There are 7 FFT (fast Fourier transform) based algorithmic spectral types. Including a Phase Vocoder, spectral blur, spectral re-synthesizer and more. There so much you can do with any one of these and you’re still only just getting started with this app.

The 12 total variations of the DSP effects bring a truck load of sound effects goodness to the table. Basically there’s 3 variants each of the 4 effects units.
Multi-Mode Filter, Stereo Glitch Delay, Micro Cutter, Phaser Reverb, Modal Resonator, LoFi Delay, Bouncer (Cutter), Ball In The Box Reverb and more. Each have something special to offer. csSpectral is a big scary beast.
It’s just too much fun to play with sound in this.
Recording and editing the resulting samples are a cinch.

There is no rule you need to follow here. Like I said each app stands alone with its own greatness. I just happen to think altogether they make an impressive team.
It’s all going to be in how you use them, but the capability is there. Only the users themselves are responsible if they end up having a disappointing experience.

Effectrix – Review

Effectrix is made by Sugar Bytes
Available in The iTunes App Store

“A professional multi-effect sequencer for iPad”

20140220-221057.jpg

Like many of you I have and enjoy Sugar Bytes other iOS apps. Turnado, WOW Filterbox, and Thysis each having some great things to offer.

Effectrix is uniquely it’s own breed. While it does contain similar effects found in their other apps (minus Thysis) it is not just another effects app.
The 14 “intelligent” effects are thrown onto a sequencer matrix for some unusual and sometimes perfectly chaotic looping sessions.

Fun is an understatement. Sugar Bytes does have a way with creating interesting and useful apps that promote creativity. They also have a unique talent for making their programs ridiculously fun.
Effectrix is something to get blissfully lost in as you explore the infinite combinations of effects sequenced to your specific liking.

It’s a perfect interface for making sequences and easily applying any combination of the 14 FX, or all.
The familiar randomizer or “Dice” are present and accounted for.
Plus a large collection of presets that suit most any event. From weddings to witch burnings, and everything else.

There is a bit less specific or detailed FX controls such as found in Turnado, but these aren’t stripped down effects at all. The most important parameters are there for your tweaking needs.
2 assignable modulation parts per effect allow quick and easy automation of the selected options. Full expressive control is standard.
Apply the effects on the matrix by touch, and or drag along its open bar through the width of it.
Easy!

Effectrix fits any iOS workflow with support for Virtual MIDI, Network, Clock Sync etc. Inter-App Audio, Audiobus, and AudioCopy/Paste all here.

Want to have some fun with music from your iTunes playlist? No problem, a integrated audio player and recorder come with Effectrix too.

This app brings a new form of effects sequencing to the table and should not be missed. There isn’t a whole lot one can say about this. It’s just damn good.
Winner.
