If I remember correctly you can pre-record tracks on the SD card for keyboards, guitar, sound effects, etc. on the JamMan for accompaniment during live performance as long as the SD card has enough memory. Is there anything out there newer or is the JamMan still the go to for this? My band has tracks isolating keys from several of our CD's and I was thinking of seeing if this would work for live gigs. We're a three piece and we sound big but looking for "bigger".
