The contents of up to four
cards could be loaded at once taking the number of sounds available
for use up to around 40 in total.... quite an achievement at the
The DDD-1 also had a simple mono sampling facility allowing
you to augment the sound set with your sounds but this required
the purchase of a special card.
The DDD-1 had 14 pads to which sounds could be assigned.
Unusually for this era, these were velocity sensitive. Dedicated
keys also allowed you to program in flams and rolls. There was also
a TAP TEMPO button which was pretty unique for the time. On the
rear were six individual, assignable outputs plus the main stereo
pair. There was also a trigger output for synchronising older arpeggiators
and sequencers but it also had MIDI.
Programming was by way of a 'matrix' - you selected the
row and the column for the parameter you want to edit. It sounds
a bit cumbersome but the functions were logically arraned into pattern
editing, song editing, sound editing and system setting. The sound
editing functions allowed you to adjust tuning +/- 1 octave, decay,
level, velocity sensitivity as well as output assign.
