In relation to the example that you shared (fantastic), as you commented the configuration was this:
It would sound the same with a Flex, but with PUM you have a permanent monitoring.
T1 = PUM Comp Eq
T2 = NEIGHBOR Filter Chorus
T3 = FLEX, Recording T2, played with pitch - 12
T4 = FLEX, Recording T2, Fx
T5 = FLEX, Recording T2, played with pitch + 12
T6 = FLEX, Recording T2, filters for “drums”
T8 = Master Fx Reverb
In this way, you record the loop in the Pickup and manipulate it from the Flex.
How would you do the same without the Pickup? Is it possible to do it with a Flex, controlling Rec / Play with a foot controller? (hands free)
The problem that I see him doing with Flex without PUM is that you have to arm the REC when you want to start recording (but if I have my hands on the guitar… I can’t re-arm) and then to continue playing on the loop or add more layers you would need 2 Flex, am I wrong?
