I have wanted a small Midi Controller to go along with my Roland GR55 for some time now. Finally... the MeloAudio MIDI Commander. This is a powerful, small, and well built midi controller. I was able to use it with Ableton Live and my Roland GR-55, and it can be used with many products that have MIDI CC and PC commands. There are 8 presets and some are pre-programmed to word with popular guitar effects like; JamUp, Bias Fx, AXE FX, KEMPER and more. There are two 1/4 jacks to hook up two separate expression pedals if needed.
