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

cpu HD63701Y0P The sample edit is limited to 2 parameters:

- pitch tuning (7 semitones range)

- mix volume

 

 

edit WAVETABLE internal ROM (at IC15) UPD23 contains 30 PCM waves at 8 bits resolution and 25 kHz sampling rate.

edit
SEQUENCER recording patterns is similar to Roland TR-707 system with some dit options e.g flame, accent, swing and shuffle an d 2 recording modes: realtime or step.

sequencer SYNC 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, however the trigger out is always handy to sync other drum box or synth arpeggiator.

editMIDI sounds can be assigned to a specific MIDI note and triggered dynamically (limited to 6 levels) by Midi devices, but no other special controls or CC#.



edit 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.
