Title: S/H Lfo Freezes for some voices
Post by: Cpt.Credible on November 24, 2021, 08:33:18 am

Hi!
I really like the slewed S/H on LFO1 and LFO2 and use it in most my patches, however I keep experiencing an intermittent bug where both the S/H and the slewed S/H just stop, but only on a few voices. The Sine, Saw and square LFO keep running as normal for the affected voices though. ???
Sometimes saving and reloading the preset fixes it, other times I seem to have to go through a few other presets and then back for it to start working properly again.
I haven't found a way to reliably reproduce the problem, hoping its a software bug that can be patched.

Anybody else experienced anything like this ?

I tried getting this for maybe 10 minutes - it didn't hit me during that test, but it may not be nearly long enough if it's intermittent. Will keep an ear open for it.

It happened again, and I made a video documenting it:

fixing the bug by saving patch, changing patches, and then reloading the patch:

What's going on indeed... (still haven't had it here)

You haven't by chance found a pattern for getting into that state?

In any case, be sure to submit that report to support. I'll also bring it up in the testing forums.

Not yet, not for lack of trying though. It's always LFO2. But then I always tend to go for LFO2 first (because the knobs are closer I guess) so it may easily be just because I use that LFO a lot more.

Ah - I tried both LFOs, but mostly LFO 1 (which is my go-to LFO :) ). Will test with LFO 2 on my next session.

I think this is the typical scenario it has been happening in:
I have loaded up an Init patch (by navigating to one in the last bank), and spent a good 10 minutes at least on oscillators, oscillator levels, filters, some vca and vcf envelope tweaks and possibly a little tweaking of the reverb and chorus.

Then I select s/h slewed on LFO2 and crank the rate up to max and route it to pitch global.

I submitted a support ticket.
