Title link takes you to shots pulled via this auction.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."

This is very good way to do this modification. Most people just pull the audio signal off of the circuit and run it to a jack. While that works, using a bread board to amplify and filter each audio output is the better way to go. That being said, for $700 you could get two Multi-Traks much already have individual outputs.
ReplyDeletemulti-traks do have multi outs but they do not have the CC control that the six trak has. multi traks can not be CC controlled. i dont know why SCI didnt build in this feature as it is part of the six trak spec. this makes the six trak more powerful from a midi spec perspective than the multi-trak and allows midi control of parameters of the 6 individual voices.
ReplyDeleteThis has been listed on my local craigslist for quite some time. I've always been interested, but can't bring myself to spend that much on a Six Trak. I figure $500 CND would be more reasonable, but I'm sure someone will be willing to pay the asking price.
ReplyDeletelyndon, do you mean in toronto? i listed it in on the toronto cl but for $600 which is equivalent to $500US. that was my rationale. with the multi-out mod i think this is a fair price based on what i have seen stock six-trak's sell for.
ReplyDeleteplexus,
ReplyDeleteYes. I'm located in Kitchener, but there are never any good instruments posted there, so I check the T.O. list all the time. I actually wanted to buy yours, but couldn't afford to part with $600 at the time.
kitchener used to have a very strong electronic musician community, i think partly because of its german heritage. kitchener was called berlin until the name was changed. waterloo still hosts oktoberfest. anyway, you know all this, living there. i moved from there in 1994.
ReplyDeletethe six-trak price is based on the average price a decent six-trak sells for plus fair value for the multi-out mod, which transforms the synth into an incredible instrument. with the addition of an inexpensive 'knob box' like the behringer BCR you get 6 independent analogue mono synths under real-time knob control! very cool. thats how i used it.
this is a clip where i am using the six-trak with the multi-outs live. the sequenced synth parts are the six-trak, controlled by a schaltwerk step sequencer. you can see 2 BCR knob boxes above the yamaha CS15 to the right.

Greetings,
ReplyDeleteI'd like to give a little history about this modification- I've had it posted for several years (including directions and comments). The mod that Plexus nicely added to his Six-Trak was designed by G. Montalbano in 1986. Greg the article to Polyphony but it was never published. For more information about the mod (and several others) please see-

Somewhat related to the above subject: is there still any other modular synthesizer owners and / or builders in Kitchener, or am I the only one here?
