GeoSynth now supports Audiobus! It’s been a really long wait, but it’s finally become far more useful. Geo has been a fine midi controller, but was stymied by having no significant updates for ages. That’s over, and GeoSynth joins the ranks of the best and most useful music apps.
It’s been one helluva push forward for new iOS music apps and Virtual Core MIDI recently. The technology is really a happy accident of sorts. Developers are exploiting some electronic doorways to create a feature that allows us to have MIDI controllers on our iDevices that control other apps running in the background on the same device. Cool huh? No more wires needed. Of course the standard wired MIDI support is featured for those who still enjoy being tethered to their external hardware. GeoSynth is the latest to exploit the Virtual Core MIDI feature (VMC), and brings us probably the most unique of virtual MIDI instruments with a very logical and colorful interface.
Easily one of the more expressive playing surfaces that can be configured to fit your playing styles.
A lot of attention went in to GeoSynth to be a premiere live performance instrument utilizing the touch surfaces of which ever iOS device you prefer. It’s hard to not feel like you’re playing a futuristic instrument from Blade Runner or something. Tapping and or dragging your happy fingers on the cells and anywhere in between, and exploring the wicked pitch bendy responses between notes makes for a grand time. It’s truly a spectacular instrument, and way too much fun to play!

GeoSynth features many of Jordan Rudess’ custom sounds. The team really chose some very cool sounds for the 40 presets covering a fairly wide range of moods and flair. If you aren’t satisfied with those, well, it’s a MIDI instrument so go get your own. No problem. I’ve been enjoying all the presets offered, and exploring Geo as a VCM controller for Arctic Keys running in the background on my iPad1. Very cool, but I found that my iPad1 is grossly under powered. The quality of the experience diminished in result. However with some careful tweaking of the settings, and trying to not do too much all at once, I was able to enjoy the pleasures of VCM, and Arctic was able to record my brief session which I then was able to copy and paste elsewhere.
Which brings me to my next point, and serious gripe.
Being such a technological advance that Geo is, taking great advantage of the newest wireless capabilities as well as supporting standard MIDI connectivity, there is NO recording, or audio copy paste? To me, it’s a glaring omission that defies logic. I might even call it a blunder. It’s quite baffling to have such an advanced virtual instrument that plays and sounds so damn amazing, but utterly fails to include the most fundamental of expected iOS music app features: record, and ACP.
To be fair if you are already hooked up to an external set up or whatever, don’t care about mobility, and love your cables then rock on, this is perfect for you.
For the rest of us, this lack of basic sharing many of us have come to expect renders the instrument inert. More or less a very cool toy.
I did email Wizdom Music and asked, WTFrak? I received a very nice response from customer support that, and this isn’t a quote, but for sake of being brief boils down to this; development is ongoing, there always remains the possibility of additional features being added to satisfy users. Vague, but not a hopeless response.

This is perfect for live performances, and is highly responsive to user input on the fly.
GeoSynth is too cool to pass up. Be patient. If you’re like me and feel a tad maligned by its lack of basic recording and audio copy paste features, I believe it’s a safe bet they will address this soon. Fingers crossed.
I’m scoring it twice.
3 Stars for folks like me who are entirely wireless, waiting for Recording and ACP.
5 Stars for those wrapped in wires, and not concerned with mobility.
Either way, it’s pretty damn nice! Now available in the iTunes app store:

No Update!?!?!?
I thought it curious that despite the developer comments, GeoSynth updates have not been err…updated. What the flip?
* Previously I had entered a lot of my own opinion in this updated review. It turned into some rant. Really I should not have. This is a review not an OpEd. I also suggested this is of no use as anything but a MIDI controller. That was stupid. Of course its used very well as a controller. That’s what it is after all. I made the wrong point while I was displeased with the lack of progress. Sorry to my dear readers for that absurd comment. My point was to suggest that having this developed a bit more for a wider range of uses and convenience is what has been lacking. It doesn’t desperately need Audiobus as whatever it controls (Such as virtual midi) sends the audio from its AB input to record in whatever output. Its just a bit of a hassle not being able to start the recording from within Geo. I would be more forgiving if it hadn’t been so very long without any significant updates.
The issue that I failed to express concern for was about trusting further development. Geo is a great controller. One of the coolest around. The question really is, should it be bought considering its not seen any significant developments for over a year? Part of what I weigh my recommendations on is trust. I think that is important. That said, and despite how much I like Geo, I can’t honestly recommend it as is.
ACP was spurned, then offered as an expected compromise, then forgotten. Audiobus has arrived ending the AudioCopy/Paste debate, and (Thank God!) the need. Will GeoSynth ever grow?
