Meet Phaedra...

by Chris Randall
 



In my ludicrously ample free time, I've been working on this bad boy, Phaedra. It is an "analog" style four-channel MIDI sequencer for the iPad. Click the picture for the full-rez screenshot. In the interests of full disclosure, I borrowed heavily from the Moon Modular 568 Quad Sequential Trigger Source, which you can read all about up in here.

I still have a long way to go, but it is coming along nicely. Each step has note, velocity, gate time, and a pair of MIDI CCs of your choosing. I haven't yet coded in the chaining feature, but it'll be able to do 4 x 32, 2 x 64, and 1 x 128 modes. The steps can be 32nd note, 16th note, 8th trips, and 8th note, and each "bus" can run in arbitrary lengths. The "Live Control" knobs on the left can be used to modify one of the four destinations.

I haven't yet conquered "MIDI background mode," as used by many iPad synth apps, but I hope to include it, as well as Korg's WIST. It already does normal hardware MIDI and Network MIDI fine, though, and can clock, or be clocked from, an external source.

I have no idea when I'll have this done, as I'm only working on it in spare moments, but I hope to be done before Christmas. I'll keep you posted. Note this is not an Audio Damage product. (I know that even though I say that, and it clearly does _not_ say "Audio Damage" anywhere on the UI, all the other blogs that pick this up will say it is. You can lead a horse to water...)

EDIT: I made a simple video showing Phaedra driving my modular and a DSI TETR4, while clocking an Eventide TimeFactor.

How do knobs work on the iPad as parameter controls? Up//down like a slider or left/right and turn-y?

Sign me up if you're doing beta too. I have Plinkton, Dronestation and SimpleMidiPad. But this will take the cake. Let the Tangerine Dream emulations begin!

Sooo cool!! Can you customize the led colors? Sounds cheese but hey, I'm a sucker for white blue blinks! I'm in on that thing regardless. :)
