The OCTA is a four-voice analog percussion module in 18 HP: kick, snare, and two percussion channels that cover hats and metallic sounds. Where most drum modules give you one voice and expect you to buy three more, the OCTA gives you a complete rhythm section behind a single panel.
Four analog voices
Each channel is a discrete analog voice with its own decay, tuning and character controls, plus a dedicated overdrive stage. The kick has the weight you want without tuning tricks; the snare sits between the 808 and 909 traditions depending on where you set the noise and body balance; the two percussion channels reach from tight closed hats to metallic clangs.
Routing
Every voice has an individual output as well as a summed mix out, which is the routing flexibility that makes the module usable in a real workflow: take the mix when you want speed, split the individual outputs when you want to process the kick separately from the hats.
Power and depth
Here the honest caveat: 40 mm of depth rules out the slimmest skiffs, and the -12 V draw of 115 mA is high for the module’s size. On a generously powered case it is a non-issue. In a power-tight rack it is the number to check before you buy, which is exactly why we publish measured current figures.
Verdict in practice
Sequence it from an external drum sequencer and it locks in immediately. Push the overdrive past three o’clock and the kick develops a genuinely aggressive edge that suits industrial and broken-beat material, and cross-modulating the snare decay from the kick output gives you the movement that makes a pattern feel alive.
