Sequential Circuits Split-8

Sequential Split-8 Image

The Split-8 makes for a very nice programmable polyphonic analog synthesizer with complete MIDI implementation. With 8 voices and 8 oscillators (Curtis 3394 SENTE chips) the Split-8 is a heavy contender against the Roland Juno-106! However programming the synth, while straight forward and intuitive, is limited to adjusting one parameter at a time assigned to one Data knob. This limits performance ability but is no problem during studio use.

The keyboard features splits and layers, all of which can be saved with patch data. Choose between 8 voice polyphony with 1 oscillator per voice, 4 voice polyphony with dual oscillators per voice, 2 voice polyphony with a mega 4 oscillators per voice, or the unison mode which is just a fat 8-voice solo mode for trance bass and lead heaven! Similar to the Juno-106, the Split-8 uses a Chorus effect to liven up the sounds. Sonically the Split-8 sounds much 'thinner' than a Roland Juno-106, however this 'thin' sound is characteristic of Sequential and is quite nice. The wooden side panels definitely give the Split-8 that vintage flare!

Definitely a synth that CAN make crummy sounds. But also some very nice ones. All a matter of avoiding the weaknesses :-). Like many of the era dac resolution isn't great so envelopes sound bad with extreme resonance on slow sweeps etc. I found some inspiring sounds with it though. It's got it's own unique niche...not quite as wide a niche' as the multi-trak in my opinion.

I found one of these for 40 bucks and will probably be picking it up

seems like something fun and cheap to add to the tool box

Split 8... all I can say is it sounds very harsh, but not a good harsh. Didn't like how most parameters have values 1-15, not enough resolution for precision. Has a steppy filter, can't get the greatest filter sweeps unless you move the knob slow.

I feel the addition of knobs and double oscillators would have made the difference.
