Summary0000718: Some VSTi's not starting/resetting after being stopped
Description

Very rare bug in which a plugin (loaded into Chainer) has problems playing notes after stopping a track. The specific plugin in this case is u-he's Zebralette plugin, but i've composed quite a few tracks with this plugin before 1.25.02, and this problem was never noticed.
After selecting a plugin's preset and playing a pattern that calls that plugin, the notes play normally. But if i stop the playback or the track ends, the notes will stutter at first playback afterwards, and not play at all in subsequent starts.
The remedy is to change the preset but this erases any modifications that were made. The next playback is back to normal, but only till the playback is stopped or ends.

Steps To Reproduce
  1. Create an instrument that calls Xlutop's Chainer VST.
  2. Load an instrument in one of its slots, specifically u-he's Zebralette.
  3. Select a preset that has an immediate sound.
  4. Create a pattern that plays a note or two of the plugin.
  5. Make sure the instrument's MIDI channel is the same as the one chosen for the slot.
  6. Start unlooped playback. Stop it or let the pattern end.
  7. Start playback again. The instrument will stutter.
  8. Stop and restart. The instrument won't sound.
TagsNo tags attached.

That plugin works just fine here. Have you tried to use it without Xlutop?

Closing because the plugin still works fine here. It must be either a Chainer issue, or maybe an outdated plugin version.
