■Rackmount drum brain based on PCM samples with analog triggers and basic Midi control.
Main panel features a 40 X 2 LCD display, 13 push buttons and headphones.

■Each kit is composed by different samples/sound at 16 bits from the internal ROM assigned to a specific Midi note. TMX Sound edit is limited to 3 parameters:
- volume gain
- pitch tuning
- stereo panning position.

■PCM WAVETABLE a pure rompler module: internal wave ROM contains 245 samples at 16 bits resolution
curve. Percussives sounds and drum kits are organized into 6 sounds categories: kick, cymbal, snare, tom, percussion and synth/ effects.

■TRIGGER signal input gain and threshold can be set manually or automatically using the AUTOSET function. Special Crosstalk Rejection function manages possible false hits.

■ENVELOPE the voice edit features 4 preset velocity curves.

■SEQUENCER some TMX functions are optimized for sequencer QY-10 or QY- 20.

■ MIDI module can be used as a Midi expander module but relative implementation is rather poor and manages only the Velocity Levels.
