tetra potential voice issue?

tetra potential voice issue?
« on: October 17, 2022, 06:58:02 AM »
Just got a tetra second hand, but am running into a weird issue where voice 1 sounds noticeably different than 2-4. Don’t know how to explain it other than it’s very noticeably quieter, duller, and thinner sounding. I’ve tried the calibration twice to no change. Ive also tried opening the filter all the way up and tried different wav forms on each oscillator to try and narrow down the issue but I’m just kind of grasping at straws.

Anyone have any other ideas other than potentially looking into replacing the whole voice chip (also is that possible with these?)

Thanks.
