Get ready for some tablet patching. A developer has revealed a port of popular open source modular environment VCV Rack to the iPad.

Synth Anatomy gets the scoop on this one. New Zealand-based developer Vitaly Pronkin has been working on a project that promises to put the free rack synthesizer platform on the iOS app store soon.

The most encouraging thing here is probably seeing an easy interface for adding modules from VCV and third parties. That would open up an additional platform for developers’ modules.

Don’t get too excited too fast – this is best seen as a proof of concept, especially since it forks an earlier version (0.x rather than 1.0). But it could be a good indication of performance on Apple’s tablets, and might well be the basis for a more polished, finished project.

VCV Rack 1.0 is licensed under the GPLv3, which generally is not allowed on Apple’s App Store. (There are some loopholes, as we discovered when licensing the iOS port of Pure Data, libpd – but that has to do with the fact that Pd itself is under a more permissive license, and patches, for instance, are not compiled.)

Another way to go if this is what you want – try running Rack on a Surface or similar Windows tablet. That also allows greater compatibility with your usual audio tools than you get from iOS, and without Apple’s App Store restrictions.

I’m still happy with Rack on a PC, where it can take advantage of some unique performance enhancements, and instead externalizing control. (Playing live, I don’t really want to be re-patching at all, but that’s me…)
