Yamaha TMX
Drum trigger module (1993)

 

Rackmount drum brain based on PCM samples with analog triggers and basic Midi control.

RACKMOUNT Main panel features a 40 X 2 LCD display, 13 push buttons and headphones.

Back panel terminal connectors:
- 12 analog triggers (including hi-hat) inputs
- Midi interface
- main signal out
- aux analog out

- program change pedalswitch input.

Power supply is a 15V external PSU +)- polarity.

TECH Main CPU H8/532 - 6435328 with a 16 bits DAC based on Burr Brown PCM56HP + dedicated IC YM3029 (floating point converter same found on synthesizers SY55 and SY99)- spotted also an unknow SMD IC YMW269-F.
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

Percussives sounds and drum kits are organized into 6 sounds categories: kick, cymbal, snare, tom, percussion and effects. Hear drum kit 1

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

TIP: Special "ZAP" button enables sound preview (pic wikipedia)

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.

MEMORY:
- 25 ROM kits
- 8 RAM kits
- 32 performances
TIP: Setup can be saved to Midi dump.

-LEFT - RAM system works with a CR-2032 battery soldered to the mainboard, replacement involves soldering. - click to enlage picture-
