For you Tripleplay controller/Sonar users, I have a basic question: If I want to have multiple midi tracks with various soft synths, do I need to add a Tripleplay each time? For example, I add Tripleplay and use Omnisphere (triggered within Tripleplay)on a track and then I want to use Tripleplay to use Ivory II pianos.
 
thanks!

I am not a triple play user but it should be the same as for any midi controller - as an input on each instrument track (or each MIDI track associated with each softsynth). Then, use the Input echo button on each instrument track/MIDI track to trigger the ones you want to hear (either one at a time, or multiple).
The trick is in assigning midi channel numbers - for example if you have everything on your Triple Play's Channel 1, then every synth with Triple Play Channel 1 as its input that has the input echo button engaged should sound when you play your controller sending to channel 1. You can be as selective as you need to be in choosing your channel assignments.
Hope this helps. Good luck
