Hey, ive already got sample in jack and pot (for sample level) midi and sample jack/mic switch. Im trying to mod it so i can have a true stereo output, like the headphone socket has. Does anyone know which points i tap from for left and right outputs?
isaac
Does the VSS30 have any kind of true stereo? Isn't the headphone output just dual mono?
If so you might as well just duplicate the main mono out.
hmm, i did wonder. probably why i couldnt find anything on it. cheers :)
i have just checked mine its defiantly a dual mono output
ok, thanks :)
I made a stereo mod to my Casio SK-8, so it might be possible to do it also on the VSS. My mod relies on the fact that the SK samplers has 4 separate analog voice audio lines out from the processor before they get mixed into a mono out - one for each voice of its 4-note polyphony.
If you can find a point on the Vss circuit board where the voices become independent (this will possibly be directly out from the processor) then you can tap each voice out at these points and re-mix them into stereo with a simple passive mixer, which is what I did with the SK-8. The SK-8 uses dynamic allocation for its notes (meaning each time you press a note, it comes out of a certain audio line, press 2 notes and it comes out of the 1st and 2nd line etc and swaps around depending on if the audio line is already in use etc. So the same note can come out of a different line, depending on if it that line is already in use by another note. If you mix the 4 lines into stereo then you play a note and it comes out the left speaker, play another note while holding the first and the new note comes out the right speaker etc and you get this panning effect, depending on how hard left/right your voices are panned.
Regarding the Vss, this all depends of course on if the Vss has separate lines for its voices. The service manual should show this. Anyone got one and can look it up for us?

Any chance for some pics or drawings or something please?

This sounds cool. Send some pics, drawings or something please to help the newbs
Sure! On the SK-8, these are the 4 voice audio outs. I think it is the same for the SK-5 also. The SK-1 is different (I don't have one so I don't have a pic) but it is just as easy - I think someone asked about separate outs before on this forum, you could find it doing a search. I think it was for the filter bank.

Some of you make it look so easy. Not sure what I was afraid of all these years. Now to find something to bend.

That's genius!
