Yes, it sounds like you are trying to use the same instance of the VSTi multiple times.

You have to assign multiple instances to different ports for each track as Lyn described above.
example- track 1 - port 17 assign the synth
track 2 port 18 - assign the synth (so it is another instance of the synth on it's own)
track 3 port 19 - assign another instance of the synth
etc.

Otherwise you are only running one synth and trying to control it from different windows, which will defeat the last change you made.

Use 'save preset' to save sounds. Usually the plugin will save in a default directory, so when you go to open presets later they will be right there.
..or you can pick a directory if you want, but I usually use the default.


If you are able to use multiple instruments at the same time from this VSTi (by design), then it will not be necessary to use multiple ports, instead you would need to make sure each instrument is on its own midi channel. Is it a 'one sound at a time' synth?

I do not work here, but the benefits are still awesome
