You can record 4 tracks at a time if you configure the outputs as “Studio Mode” and then adjust level and pan for each track. Of course each track will be mono, but depending on your samples and processing, that may be perfectly fine.
I’ll typically have:
T1 set to Main 127, Cue 0, Pan L
T5 set to Main 127, Cue 0, Pan R
T2 set to Cue 127, Main 0, Pan L
T6 set to Cue 127, Main 0, Pan R
