So here is a bug that keeps coming up for me for a while now. I am only posting about it now because I had assumed it was a bug that would be fixed by an update. I am running JJOS2XL ver. 3.23. It only started happening when i upgraded from ver. 3.18 to 3.19.

Occasionally, triggering samples on pads results in wobbly pitch to the sample. It is as if an LFO is modulating the pitch. The workaround for me is to go to the LFO settings and set the Delay and Freq go max values. The problem with this method is it renders the LFOs useless. It doesn't happen all the time, but when it does its **** annoying, and I have not been able to figure out what it is that causes it. Maybe the CPU is getting overworked?

Just wondering if anyone else has experienced this issue.

Peace,
JJ

It does respond to mod wheel/ Have you got a midi device like keyboard going into mpc ?
Is it still there when you set LFO to zero? Or foes the time change on the sound as you change LFO time ect?? Mod wheel will over ride it

i've noticed what may be this bug once while using recorded pitch bend data (forget whether it was qlink or proper pb)

LFO is not engaged in this situation

recorded a pb, and then copied the seq for a later version.
in the copied version, it wobbles as if with a pb. i have not examined this too much. i try to stay clear of qlink realtime stuff in favor of using midi ccs.

yall be some clever mofos on this board... thanks for help. I got a controller keyboard connected to the mpc which then goes to my hardware synths. the mod wheel is a bit loose and doesnt always sit a zero... i have to open it up and tighten the wheel every few months. i never associated mod wheel with pitch modulation and probably would have gone on claiming that JJOS was the culprit! thanks for help sir.

mods could prolly move this out of the JJOS subforum
