edit
TECH main core based on CMOS 8 bits CPU HD63701Y0P which manages 8 channels polyphony.

STRUCTURE
Each TR626 voice has a sample assigned from 4 different ROM banks (rompler) with some channel-shared restrictions e.g: you cannot play SNARE 1 and SNARE 2 at the same time.
The sample edit is limited to 2 parameters:
- pitch tuning (7 semitones range)
- mix volume.

 

cpu HD63701Y0P

 

edit WAVETABLE internal ROM (at IC15) UPD23 contains 30 PCM waves at 8 bits resolution / 25 kHz sampling rate.
PCM are mainly sampled from acoustic drums and organized in 16 categories: kick, timbale, hihats, cup, snare, crash, cowbell, handclap, tomtom, cymbals, tambourines, claves, rimshot, ride, agogo and shaker.

edit
SEQUENCER recording patterns is similar to Roland TR-707 system with 2 recording modes:
- real-time
- steps by step.
Some edit options like including: flame, accent, swing and shuffle.
MIDI sounds can be assigned to a specific MIDI note and triggered dynamically (but only 6 levels) by Midi devices, but no other special controls or CC#.

 

sequencer

 

editSYNC internal tempo range from 40 to 240 BPM or slave-synched to:
- external Midi clock
- tape sync protocol.
TECH: SYNC 24 is no more implemented in 626 - time for MIDI! however the trigger out is always handy to sync other drum box or synth arpeggiator like Roland Juno-60.

MEMORY:
- 48 ROM patterns
- 48 RAM patterns
- 6 songs (maximum of 999 steps)
RAM is tripled using Roland M-128D card, usually cheaper than m256D used by Roland D-50 or JD-800. Patterns and songs can be also saved to Midi sysex dump or using the obsolete tape interface.
Battery replacement: soldered CR 2032 3V (see picture below)

edit MODIFICATION a common operation modding for TR-626 is the circuit bending: bent points are often modular of activated by levers.
If you like stretched glitches sounds this could be a nice job for your machine.
