Hi. I'm new to the group. Purchased my P1 last month and have been struggling with this subject ever since. There are a lot of gaps in the manuals (h/w and s/w), so I'm glad to see this group. Through trial and error here's is what I have found: 1) .wav files via the SC card play back fine. In my few early experiments the volume seemed lower. When in this mode, no other resources in P1 available. Any other live parts would need to be played on another instrument. 2) importing .mid files via card and playback had same results, just different format 3) creating phrase sequences from small .mid files best results yet becauase it offers more control, BUT a drum set needs to be selected resulting in additional drum note triggering when playing the keyboard while sequence is running. Can drums be layered but triggered only by the phrase sequencer? My goal: create drum and base sequences in my DAW, xfer to phrase sequence in P1 and loop sequence as accompanament while playing single tone lead or pad. Is this Do-able?? BTW, I'm trying to avoid using the step sequencer. It doesn't suit my style of playing (jazz/40's-60's standards). Many better drum patterns available as .mid files than I could ever create via step sequencer. Thanks Al
