OSCILLATORS main core CPU NEC D650C-128 (MASK ROM) manages 5 channels each with dedicated volume mixer section..
EDIT INTERFACE quite simple with some keystroke, just select and instrument from knob selector and push play. Voilà.
SOUNDS: Voiceboard generate 7 instruments: kick, snare, tom (x2), cymbal and open/close hh
SEQUENCER is based on classic Roland step mode recording or realtime using the tap button. Default signature is set to 16 steps, but the scale selector can modify to wished value.
SYNC internal tempo set from 40 to 300 BPM or It is possible to slave the machine using the sync 24 (like tb-303 or mc-202). Another useful synchronisation way is the trigger: simlpy fill the 606 TOM steps and plug it to some synth arpeggiators or simple sequencer like Elka Synthex or Roland Sh-101
MEMORY - 32 patterns
+7 songs. There is absolutely no way to backup your songs or patterns.
HINT: When switched off the machine retains the memory if 4 C-size batteries are fitted, and when RUN led begins to flash, it is time to get fresh new batteries! just remember that it is wise to remove them after a long period just to avoid acid leaks.
MAINTENANCE If buying a second hand just watch out for the famous ALPS buttons that may need some replacement, but pay attention to cheap replacement parts.
