Hi John,
if I understand correctly: Pianoteq is running on your computer using
JACK in some LV2 host or maybe as a standalone application?

Does Pianoteq have a sequencer that you use? If you play live, It
wouldn't matter whether Ecasound in master or slave mode. If some sort
of sequencer is running in Pianoteq, then it's a question of your
workflow. What's the centre piece? If it's Ecasound, set Ecasound to
master (transport master) and Pianoteq as a transport slave.

>From my understanding of Pianoteq, setting Ecasound to transport Master
or leaving it open, is the right decision.

Best wishes,


When you need someone, you just turn around and I will be there <3
