When my Filter “FREQ” parameter is high enough every eighth key I play will skip or just not play. Sometimes it will fizz in or bubble in or there will be a bump sound before or during the note plays or sometimes the eighth note won’t play at all. Turning down the Filter “FREQ” parameter usually gets rid of the problem but I don’t like knowing that there are some sounds I can’t get too. Any ideas on what might be causing this? I have done Filter tuning and everything checked out. (Values were between 146-153.) I have played eight keys with the filter “FREQ” turned down and all the voices seem to be function as in when I press down nine keys the first key cuts out as it should. I have done all the tests that I could from the outside of the synth, everything passed, and have not opened it up yet. Could this be a software problem? The software version is 3.40. I did do a factory reset and it did not help or atleast I don’t think it did. I will be updating that in the future and I do plan to open it up later today or tommorow. I do have a vintage synth repair place near to me and was wondering if any of you could point me toward the problem or even a possible solution. I have been asking around on forums and noone seems to know whats wrong… well actually noone seems to care as I have gotten no replies. The guy I bought it from does except thirty day returns but I would rather not go that route unless repairs seem too expensive. I really like this synth and really want to get it working! Any help would be greatly appreciated! Thank you.
Here’s a video that demonstrates my problem that I took. https://www.youtube.com/watch?v=HgbGoGjwuSI
