View Full Version : How to eliminate pops caused by sawtooth LFO?

I've got a sawtooth LFO controlling filter 1 cutoff, and I'm getting low frequency pops that I believe correspond to the start and/or end of each cycle of the waveform. It doesn't happen on every cycle, but it happens at some point any time I play and hold a key longer than a few bars.

I've tried several things, but nothing seems to address the issue. Maybe I could try using a different waveform and mess with the contour or further assignments and slider settings in the Matrix, but this is what I want except for the pops.

Anyone have any ideas on how to get rid of the pops caused by a sawtooth LFO? Thanks.

If you have already tried messing with the LFO rate/amount/contour settings without any change then maybe it has to do with the filter settings?

I'd try varying some of the parameters:

- adjust the base filter frequency, probably set it a little higher; or
- adjust the filter envelope amount; or
- soften the filter envelope attacK

Hi there. :)

Can you give us a way to replicate the problem? Like, from the INIT patch, the minimum programming needed to replicate it.

Just tried all manners of using a sawtooth LFO to modulate cutoff, but I can't get it to "pop" other than when I add other stuff like rectifier saturation, or when using something like the arpeggiator clocked to the same speed (along with punch intensity enabled, etc.).
