Hi everyone,
I really can't believe this can be so complicated but I've spent the best part of a day trying to figure out how I can get the Play, and Stop buttons working on Machine Mikro MK3 when using it with pro tools (machinepluign version 3 too). 
My S-88 MK2 was easy to set up, it has not problems playing from the hardware.  Set up a peripheral, assign ins and outs and we're good to go.
How on earth do I set up machine to do this? It seems really silly that I can't quickly press play on it when I'm sitting in front of  the pads….  It's exactly whats needed to hash out ideas quickly.
