Ich hab meinen Boomerang Phrase III jetzt schon eine weile nicht mehr benutzt, aber ich bin mir ziemlich sicher, der kann das:
6. “Loop Play Style” There are 4 Play Styles on the Boomerang III. The behavior of each is described in detail in Section 7.
Serial Loops
play one at a time. This is great when you have a loop for the verse of a song, one for chorus, and one for the bridge. Loops are recorded, played or stacked one at a time. If a loop is playing and another is selected, the first plays to its end and stops; the second loop plays immediately leaving no gap. Your loops can be played in any order you wish.
Serial-Sync
This Play Style is similar to Serial except Loop 3 is the “master loop” and can play along with Loops 1, 2 & 4, which are “slave” loops. This allows you to create a short rhythmic loop to play along with the other melodic loops. For example, if Loop 2 and Master Loop 3 are playing together, and Loop 1 is tapped, Loop 2 plays to its end and stops. Loop 1 plays immediately, and Master Loop 3 continues to play throughout. Our recommendation is to record a short master, about 1 or 2 measures.
Sync
This Play Style is similar to Serial-Sync, but all loops can play at once! For example, if Loop 2 and Master Loop 3 are playing together, and Loop 1 is tapped, Loop 1 will play when Master Loop 3 restarts. Now Loops 1, 2 & 3 are synced.
Free
All 4 loops can play simultaneously and they are totally independent. Each loop is recorded, stacked, played & stopped without regard for what the other loops are doing. With 4 long loops playing and drifting freely.
