Midi controller / remapper app for Android

Hi Elektronauts,

I have a couple USB midi controllers lying around (Midi Fighter Twister) and some gear that only takes DIN midi (OT, DN, Volcas). The simplest way to use them together would be a USB-to-MIDI thru box, but this isn’t very appealing to me for a few reasons:

  • Need to use USB controller’s software to make any mapping changes, which requires having a computer around.
  • Limited by what MIDI the controller can send out
  • Can’t easily monitor which messages are coming through to debug when something goes wrong.

I also have some android devices and a USB midi interface.

Is there some software on android that ticks all these boxes (decreasing priority order)?

  1. Configurable on-screen controls (buttons, faders, etc) that can send arbitrary midi messages
  • E.g. tap a button to send several CCs to set Volca Drum voice 1 to a predefined kick (but leave the other voices alone)
  1. Trigger the on-screen controls by incoming midi
  2. Has LFOs
  3. Ability to pre-define midi mappings (e.g. let me map a fader to OT track 4 FX1 param 2 without looking up the manual)
  4. Actively developed
  5. Has a plugin API

TouchOSC / TouchDAW seem close to what I’m looking for, but I’m not sure if they can run internal LFOs.
