i bought an akai VX 90 off of cragslist a few months back and i was really excited to get to mess with a real analogue synth. I played it at the owners house for a good 10 minutes and messed around with some sounds, and i was pleased. I think i paid somewhere around 300 for it.
i get it home, i plug it in to my basic M-audio keystation and im messin around. I started pushing some random "advanced function" combinations to see if i could get it to do anything other than change midi channels, and all that ended up happening is my octaves went out of tune. to define that a bit more, when you play a c scale, it goes c-d-e-f-g-a-b-c, well the sounds that the synth is making is more like, c-c-c#-f-g-a-b-c.
so my first thought is, damn it. i figure i used some arbitrary midi command to swap the notes in my octaves. i read something about nprn-s in a midi book, the commands that m-audio has listed for my keyboard are relatively simple, and i tried the "reset all controllers" command, and no real difference.
so i started playing around with it last night, and this is what gets me worried, if i play the affore mentioned octave and the sounds are c-c-c#-f-g-a-b-c, ill play an octave lower, and they are the same relative notes, BUT, when i go up to the original octave and i play it, the notes are different than their orignal deviation, like, it will play c-d-e-eb-f-a-b-c. ... so now im thinkin its something more like the pitfalls of analogue synths, and that my VCO's or something electrnoic is going out on my synth.
those are the things that I have tried, any help would be appreciated , IE suggestions or whatever. I have found close to nothing on this synth on the internet, so i know relatively little about it. If ANYONE has a pdf of the manual, or knows how to address this issue, OR if this issue is even fixable, please advise. mabey its a midi command? is it worth fixing?
