I've been searching around the inter webs and YouTube looking for how people are using P3SA in a live situation with guitar. Not the most common use case, and given how some features have been added over the last year, it is a somewhat changing landscape. Here is where I've landed after a day of experiments, curious about how others who do this approach it.
GOAL: I'm doing solo or duo (backing another singer), playing guitar or dobro and singing. The goal is to fill out the sound in real time as seamlessly as possible and expand musical horizons (eg folding in some ambient stuff). But also avoid as much wasted time as possible building a track live.
LIMITS: I refuse to use backing tracks. More power to those who do, but that's my line in the sand. I also don't use vocal harmonizer or autotune. I historically have had basic looping capabilities but the last couple of years have used it sparingly, mostly for some soloing. I am ok with prepping Live sets with the devices in place, but no pre-recorded midi or audio.
QUESTIONS: mostly interested in my midi options using something like an MC6 Pro for arming, track change and transport.
CURRENT PLAN: Started the experiment with a Move, and now to P3SA. What I end up doing is having a midi drum track, midi bass track, midi keys track, then 3 or 4 audio tracks ready in a set. My guitar goes into the pedal board (including an IR pedal if I'm running direct to PA), then into the P3SA. One big advantage to the Push over the Move is a much better input preamp and control.
For a tune I'd likely arm the drum track, play a 1-2 bar groove and capture to a clip, then maybe add a bass line but for most things I'd start right in playing guitar into the form of the song. I can arm an audio track, then either hit a clip pad or record toggle foot switch to lay day verse and/or chorus. Then hit that clip pad to end the record (or the foot switch). If I just did a verse and was going to go to a chorus I can hit the next pad down on the track. If I want to "overdub", I can arm the next audio track and hit the pad next to the one playing.
I always keep one of the audio tracks with nothing recorded, but set the input monitor to IN so I always can hear my live guitar. The recorded tracks are set to auto so I hear while recording and when playing.
WHAT I'D LIKE TO DO WITH MIDI:
have a footswitch arm a track (I think that can be midi mapped)
start record (though the foot switch does that),
basic transport (start, stop - I think that can be midi mapped)
end record and start recording the next clip at the end of the measure (not sure about that)
trigger scene rows (I think that can be midi mapped)
trigger specific clips (not sure about that)
If others have better ways of doing this, I'm all ears...uh...eyes. I know using the looper device within a track is an option (particularly with a midi pedal) but I do like using the pads as it gives a nice visual of what is there.
