Hello all. I recently got a JP-8 that's in really great condition. There's just one small thing that doesn't work and I'm not sure how to troubleshoot the problem.
When I engage the ON switch for the VCF bender, it doesn't respond to bender changes, even with the slider set to the max.
Both VCOs respond (independently, as designed) to the bender when their switches are in the ON position. However, raising the VCO bender sliders changes the pitch of the current note even before the bender is engaged. This is unwanted because the pitch is not scaled to to the keyboard as you'd expect. I don't know if this is normal operation.
If the VCO behavior is normal operation, that's OK. But in that case it seems like either the VCF switch or slider is dead.
Everything else on the front panel and performance section (lower left) seems to work fine. I'd appreciate some advice from someone who can help me get this working again. It's 99% functional and I want to get everything working.
