Multi-core processors + Multiple Instances
Unfortunately VSTs built with older versions of SynthEdit (such as this one) are not properly compatible with multi-core processors. Single instances work fine, but multiple instances can cause crashes in hosts that have multi-processor support activated. As time allows I will be working on updates to all my plug-ins using the latest version of SynthEdit, which will eliminate this bug.
In the meantime, there are a few workarounds for this issue.
1. Make additional copies of the dll for each extra instance you expect to need, and give each a new name. (eg: teos.dll, teos3.dll, etc.) Hosts consider each an individual instance, and therefore do not run into the multiple instance conflict.
2. Freeze each instance before loading another one, especially if your host has an “unload while frozen” option.
3. Turn off multi-processing in your host. Of course this is the least desirable.
FL Studio Lag
FL Studio users may experience a lag between when you press play and when the sequencer starts. A lag also occurs when pressing the rewind button. This problem is caused by an incompatibility between this plug-in and the reset procedure FL runs every time you play/rewind.
To fix this problem:
1. Press the options button in FL studio (at the top of the screen)
2. Choose the Audio Settings from the drop down menu
3. Turn off “Reset plugins on transport"
