...I am considering purchasing a M20d but have a question:
Q) Is it possible to playback a stereo pair from a usb stick (for example backing tracks) while recording to a drive or SD card?
Q) Is there a window in the M20d which could show contents of a folder containing the various backing tracks where i can select from it at a gig?
Amongst other things I perform solo in pubs etc using backing tracks. I can go through 30 or so in a session...
Ignoring the specifics of M20d technology, Gene...
...My first thought would be that human "multitasking" to the extent of trying to do all of that from any small, single screen during a live performance smacks of an "extreme sport" rather than a musical event.
To my mind, the StageScape concept is devoted to the clear (yet compact) M20d screen presenting the gigging player/s with a clear "real-time picture" of (and instant access for the purpose of modifying) what's happening "live", at any (and every) given moment of performance.
Accordingly, it seems to me that the use of portable media in our M20d is intended to EITHER
- Record our (relatively) "raw" inputs for practice and/or later re-mix, ...OR...
- Replay a relatively small number of selections for sound-check and/or "play along" applications.
So I'd be very surprised to find myself alone in heartily recommending our use of a separate and easily operable player (let's say, for example, via the "Aux In") to provide that "instant" access to backing tracks.
Doing so would not only allow us to potentially devote all of our "track space" to incoming material, but also streamline operation in terms of limiting our ongoing attention to just the performance "elements", (including the timing and selection of backing tracks) having only needed to initiate the M20d's multitrack recording at the start of "our session".
...Are there any plans to produce a larger input version or can existing M20d units be linked?...
I'm not aware of Line 6's intentions in terms of (maybe) considering something like an M40d, but you may find this discussion interesting:
