Is there a way to activate instrument only if part is detected?

I’m using templates in VEP connected to Instruments in Nuendo.
I found out that while RAM is affected by the sheer quantity of samples loaded, the CPU is instead greatly affected by how many Instruments are active. So, what I’m asking is:

Is there a way, via either PLE, track Transform or any other way, to:

  • Detect if a project track is empty (i.e. doesn’t contain parts, in most cases), and
  • Toggle the instrument activation based on this info?

Also would it be possible to do this for a group of tracks that share the same MIDI Output (i.e. Vienna MIDI Instrument 01 on all its 16 channels)?

I know how to do this from Track Controls. I just want to know if there’s a way to automate this so that only parts that refer to that instance are played, then the instance/instrument is active.

Thank you in advance. :wink:
