MIDIPen

MIDIPen turns your iPad into a drawing surface for MIDI. Put a pencil (or a finger) on a block and its X position, Y position and pressure become MIDI control changes, sent live to any synth, DAW or hardware that speaks MIDI. Lift the pen and the block holds its last value. Draw a shape and it becomes a loop. BLOCKS ARE THE INSTRUMENT The screen is a grid of blocks. Each block is a small XY-plus-pressure pad with its own MIDI mappings. Name it "CUTOFF", point it at CC 74 on channel 1, and you have a filter knob you can draw with. Show two, four, eight or sixteen blocks at once. ONE BLOCK, MANY CONTROLLERS A block is a macro. Add up to eight mappings per block, each with its own channel, CC number (or channel aftertouch), axis, range and invert switch. One stroke can open a filter, close another and push reverb send at the same time. RECORD A GESTURE, PLAY IT BACK IN TIME Hold REC, draw…
