How are you changing sounds in the 2 states? Are they different patches in the same VSTi? If so then that’s going to happen I’m afraid. If you want seamless patch changing, you’re going to need either a multi-timbral VSTi, such as Kontakt or UVI Workstation, or otherwise 2 different racks or separate instances of your VSTi, with the 2 sounds set up. Then when you change states, change the midi target of the route from your keyboard. This way Cantabile just routes midi to a different place without cutting the sound. It also intelligently waits for note off or sustain pedal off messages if you want to hold them over the state change.
Hope this makes sense, I’m away from the computer right now and it’s harder to explain with text than it would be to show you with pictures. Also, Brad’s excellent getting started vids will help out with all this…
