Re-Arrangeable Loops
The Unity6 has 6 individual mono loops that are routed in series. Each loop can be re-arranged on a per bank basis, meaning you can one loop order in bank 1 and a totally different loop order in banks 2, 3, 4, etc.
Each loop can be programmed to turn on/off individually or any combination of loops can be on/off at any given time.
Loops 4 thru 6 share the same TRS Send and Return jacks for loops 1 thru 3. Loop 1 jacks can also access loop 4, loop 2 jacks can also access loop 5, and loop 3 jacks can also access loop 6. To access loops 4 thru 6, first turn them on inside the Global Settings, then you need use two TRS to dual mono patch cables (one for the Send jack and another for the Return jack). The Send jack goes to the inputs of each pedal, the Tip goes to the pedal in loop 1 and the Ring goes to the pedal in loop 4 (same for loops 2/5 & 3/6). The Return jack goes to the outputs of each pedal, the Tip goes to the pedal in loop 1 and the Ring goes to the pedal in loop 4 (same for loops 2/5 & 3/6).
A good resource for custom made/length TRS to dual mono patch cables, is contacting our friends at Creation Music Company or Goodwood Audio.
