as I use it : home main recording setup

I have all track memory set to tr 1
got the machinedrum and or any synth etc running to the gear mixer
then mix out to input C/D
main out OT back into end mixer for fine tuning
Then send its rec out into A/B set rec on TR 1 as input A/B
adjust and record the session within the OT

for longer jams I record outside of the OT say into a H4

there are so many ways to use it, Just start out simple, for me these settings are important
1 main recording (and how much memory for the main recorder)
2 specific tr recorder say tr 2 is input A/B (drums) tr 3 C/D (synths) for looping and stuff
and you could use tr 6 and 7 for direct playback loop tr 2-3 by selecting
flex recorder buffer 2-3 on tr 6 -7

put a trig on the first step of tr 6- 7 to get the audio going and I think your off… adjust as what works best for you
