Hello all...I found this excerpt from Boss somewhere along the way, hope it is what you need...cooker
Use 16 Compressors at a time on the Boss BR-1600CD.
The BR-1600 has 8 channel compressors for your Tracks. You can assign these compressors (these are the ones that live under the "COMP" button) to either Tracks 1 — 8 or Tracks 9 — 16. But what if you want compressors for all your drum tracks and your vocals? No problem, just "borrow" the 8 compressors that live under the COSM Effects and assign them to tracks. Here's how:
Press MULTI-TRACK.
Press EFFECTS.
Press the F3 Button (LOCATION). Select TR 1-8.
Press ENTER. This assigns the Compressors and EQs normally dedicated to the Inputs to Tracks 1 through 8.
Press EXIT.
Press COMP in the CHANNEL EDIT section.
Press F3 for Track Select. Set the LOCATION value to Tracks 9-16 by pressing F3 again.
You now have 16 Compressors available for mix down.
