I have just received my Studiolive 32 SX which I wanted to connect via usb to my Akai MPC Key 61 as I did with my Tascam model 24. Unfortunately after realizing that I had to set 44.1khz instead of 48khz (otherwise the playback speed and the pitch were increased), the playback of the MPC tracks dispatched on the Presonus began to crackle and sound metallic as soon as the sound grew in instruments. So big disappointment for me. I hope for a quick update because I bought it on purpose for this use, it would bother me to send it back. If anyone has a solution, I'm interested. THANKS.
