This is a drumrack for Fxpansions Tremor drumsynth. Each Pad represents a slot in Tremor with its own audio output and a Max for Live device mapped to the four macro controls.
You will have to load the included MIDI mapping preset and have to set the outputs of the slots to Sub Output 1-8. Then save this as your default preset.
I contemplate adding other modules, such as ADSR or filter mappings. Let me know in the comments, which ones you would find useful.
