Sylenth sound changes in Logic after restarting playback

[Jessica2]

Hey guys, sorry if this has been posted already, couldn't find anything in the search.

I'm having a strange problem with Sylenth where the sound of the instrument is changing simply by stopping and starting playback in Logic Pro X. It sounds like there is a setting change to a filter.

If I start Logic and hit play, everything sounds fine. If I stop and start again, Sylenth synths all sound like they have been filtered down. I cannot get the original sound back unless I completely restart Logic, or if I change the preset and then change back to the preset I was using.

There are no program change settings or automation, I have tested this in a completely new project from scratch.

I am running on OS X v2.2.1 using Logic Pro X 10.1.1. Any help would be greatly appreciated!!

I've had this problem too, I just purchased the synth, I don't know if that has anything to do with it

I noticed this same problem over here and it seems to have something to do with the built-in phaser. I found that moving the phasers dry/wet fixes the sound momentarily until the next playback... then its back to the weird, filtered/phasey sound.
Basically any patch that uses the phaser is no longer useable with this bug
The Vst version is fine (tested in Ableton) but it is affecting the Audio Unit version in both Logic and Ableton with and without 32lives.

Sylenth 2.2.1
Yosemite 10.10.4

Well...Sylenth1 simply doesn't change any parameters or settings by itself, so in most cases these things are caused by a MIDI device or a MIDI clip sending out some kind of MIDI CC message or anything.

Just check this first
