This post must be very difficult to reply to?
Can we use midi environment to capture the Randomize out and send it to trigger pan, sends etc?
All MIDI FX send any modification to midi down the MIDI FX chain. If the last item is an actual AU Instrument, the MIDI FX stops there, but if it's a External Instrument and you use IAC or a MIDI Device looped back, then you can redirect to Click&Ports and capture what was sent from a group of a MIDI FX chain, then using a transformer and some cabling, you can modify the Pan and Sends.
You do realize that you can also MIDI Record the Modulation as Fader events as well right?
By doing this, you can just now cable that track to tracks that you want to Pan/Send and save on CPU instead of having a Modulation active.
