Hello and thanks for your reply.
I noticed the 2626 could be a great solution but as you mentionned, I'm working with a laptop (absolutely needed cause I move very often).
I saw the M-Audio fast track ultra 8-R (
https://en.audiofanzine.com/usb-inte...rack-Ultra-8R/) could be a good USB solution. Do you think it can be compatible with PT MP9 ?
Thanks again for any help you could give me.
