  • Page 3 FEATURES AND CABINET Brief summary of features Relatively uncommon 8-voice polyphonic, bi-timbral analogue synthesizer with the ability to split or layer two patches ("double" mode). 64 patch memories. Patches may be "linked" in memory so that calling up one automatically calls up the second for a split or layer.

Programmable output level for each patch. Performance features: Separate volume pots for channels A and B (i.e. the two patches in a split or layer). Programmable footswitch assignment to momentarily change patches, or change one of several patch parameters (filter cutoff, envelope amount or attack;...

Analogue fanatics mercilessly bash this and related SCI synths (the Six-Trak, Multi- Trak, and MAX) because of the synth chip that is used (the Curtis CEM 3394). It sounds a little thin, with somewhat harsh resonance on the filter.
  • Page 6 I didn't test rigorously. Rumours and speculations: Built in Japan, this was one of the last synths marketed by SCI. It was released in 1985 at a list price of $1199 (or $1195) U.S., with an optional footswitch. I have read that a “handful”...

Many SCI users complain about their high prices; however, they are a complete source of SCI parts and documentation. They also have Split-8 owner’s manuals and cassette tapes of the original preset sounds. A very useful site for Curtis chips is found at Synthesis Technology, http://www.why.net/users/paults.

The Split-8 is sometimes mentioned. Also contains a link to an ftp site where you can download the whole list.

  • Page 12 What about the memory battery? The existing 3 volt nickel-sized lithium memory battery can be replaced with any equivalent lithium battery.
