Caustic, a popular Android Acid App, may be coming to iOS as an entirely different beast! Developer Single Cell Software has announced Caustic Modular. This is a full feature modular synth designed for the touch screen... and you can play with a prototype! It is available now on Mac or Windows.

I've been playing with it this morning and it is off to a great start. You can add and remove a lot of different modules that are already programmed. You play with their knobs on the front, but the back is where the magic happens!

It is a lot like Propellerheads' Reason, as you flip back and forth between the panel and a whole bunch of wires! Knobs! Wires! Either way you look, you can't lose. The last panel is a global effects rack which adds a lot to the raw sound.

You can help Rej by poking around and giving him presets, bug reports, and module component ideas.

I've been working on and off on this prototype since February, bits and pieces in between "serious" coding sessions for the app itself. The plan for this thing is to create a new machine to add to your rack in Caustic, but I'm also thinking of releasing it as a stand-alone iPad app to test the iOS waters. But first I'd like to gather some feedback with a stand-alone PC/Mac version.

Be sure to read all of the blog post announcing it. No additional documentation is available, and this is serious business.
