Thanks for the thumbs up.
We have since moved to having the backing tracks coming from an mp3 player. But, you can definitely use the M50 to construct backing for your guitar playing. The band's mp3 tracks were originally done on a Triton LE.
Here's how it works:
You construct the tracks in Sequence Mode. Assume the M50's stereo outputs will go to a mixing console (separate left & right). With this in mind, you build the tracks and pan most of the mix elements to one channel (doesn't matter which) so that these go through the mains out to the audience. You reserve the other channel for your click track, plus whatever elements of the backing you'd like to have in your monitors. (We use in-ear monitors). Make sure to save the completed sequence to an SD card - this is the only way to play back your track using the M50's audio.
Of course, you have the option of creating mp3 files by recording the M50's audio output to a DAW in your computer-based studio. Then you can use an mp3 player onstage and feed the stereo signal in like manner to the mixing board - and you can use the SD card as a backup in case you need to play the tracks from the M50.
Here's a "live-in-the-studio" example of live playing to a track built with the M50. I'm playing live rhythm guitar. Everything else is from the M50. The track was built in stereo without a click since this was strictly an "at home" recording:
"What Am I Doing Hanging 'Round" (Monkees Cover)
Good luck and let us know how it goes.
