Voice
main cpu 8 bits 78C10 (like NEC d78) manages 12 digital voices polyphony.
Each voice has an assigned PCM waveform or sample on internal EPROM.
Wavetable
There are 18 samples on board at 12 bits mainly classic percussions.
Each sample can be edited with 7 pan positions, tune pitch (128 steps) and an assigned analog output.
Performance
each sound can be played in 3 different modes:
1- MONO: sound is retriggered at each press
2- POLY: sound finishes the EG at retrig (possible overlap)
3- EXCLUSIVE for hihat :open and close hihat cannot be played together
Expansion
DDD1 can be expanded using the optional and rare DSB-1 sampling board: 13,6 / 23,1 Khz for a max time of 3.2 sec.
Samples cannot be edited more than standard internal PCM..
Envelope
only the decay (16 steps) can be set for each percussion.
Pads sensibilities can be also set from the edit interface.
Sequencer
patterns can be recorded in 2 modes:
1- real-time with metronome (quantisizer resolution from 1/4 to 1/96)
2-
step by step mode
Roll, flames swing options (50-80%) are programmable
Memory
- 10 songs
- 4458 notes
- 100 patterns

Review
OK: cheap / 12 bits / pads
NOT : obsolete
"A pretty punchy 12 bits machine with good drum sequencer. Multi outs and Rom cards are good extra features."
