What's the trick when start /stop a track to keep the modwheel from resetting to 0?
In this case using aria Player Instant Orch. The modwheel auto resets to OFF when the track stops.
I'm playing live so not using recorded midi.
 

disable Zero Controllers When Play Stops

Go to preferences  - project - midi :   un-select ZERO MIDI CONTROLLERS on STOP.

Be aware that sustain pedal and other controllers might require an additional edit to keep from sustaining when you stop.

ARIA also has the issue that if you touch the mod wheel it goes to zero (mine are spring loaded) and is remembered in ARIA. In addition to the above, you may need to set values at the beginnings of tracks (ARIA will use its initial setting with no controller input until you touch the mod wheel).

Thanks everyone!

Hey All,
This method has never worked for me for some reason. Not sure whats up the midi. I always have to split VSTI an instrument track into an audio and midi track(s), then right click midi fader to "disable control"  just to get it to work properly. Otherwise, the VSTI output/volume control resets to 0 once I stop playback. Everytime on Sylenth1, Arturia Analog Lab and Kontakt. Any thoughts? Thanks.
