It is a 6 track multitrack recorder (to SD card) in a pedal. It looks like it can record up to 4 mono or two stereo tracks at once, and 6 recorded tracks (or files loaded from a SD card) can be mixed and output (and maybe these can be 6 stereo tracks...not sure).
I'm interested if I could use this to play a stereo backing track from SD card while simultaneously recording 2 tracks (guitar and vocal). My hope is you can select a backing track via foot buttons (it also has a foot roller control) and start playing/recording by hitting a foot button.
But I might be misunderstanding how it works...
Oh, and its $600, which is pretty expensive...
Looks cool hard to justify the money though
It kind of looks like a "worst of both" scenario – part looper pedal, part standalone recorder.
From studying further there seems to be two limitations that make it less interesting to me:
- It does not seem possible to switch between backing tracks via the footswitches
- It can record two mono tracks simultaneously but seemingly only as a stereo pair, so if you were recording two mono inputs (guitar + vocal) and connected the outputs to PA speakers, it seems one input might only play on the left speaker and one on the right speaker...
