Details: "This particular sixtrak includes a fully active buffering multi-output modification!! I built the modification. This allows the audio from each of the 6 voices output from a separate jack for each voice. The cool thing about the sixtrak is that it is multi-timbral so each voice can have a separate and distinct sound on it. Further, and this is the only multi-timbral SCI synth that does this: each of the parameters of each voice can be controlled with midi CC messages!! The Multi-Trak, although it has multi-outs DOES NOT support CC so you cant change the sounds in real time; the Six Trak ALLOWS this!!
The modification takes the audio off each voice and buffers with with an opamp so that its hot and clean. The mod also switches off the outputs when the unit self-tunes so you dont hear the tuning tone. The mono out still works as stock."
