I added a bass track. Used a Fender Jazz bass, Toneport UX2 modeling a power pop bass setting (tune pre-amp - 8 * 10 cab). I had some synchronization issues. I definitely played the notes perfectly to time of the music but Ableton Live seemed to automatically warp the recording which made it out of time a bit. The time shift is not linear. Anyone have ideas on how to fix? I can re-record again when fixed. It sounds like the entire bass line wrote to disk a fraction of a beat to late.
