So you would use a control switch to stop playback or start playback based on a certain scene?
Not stop, bypass. So while you can't hear it, it is still playing in the background. I'm not aware of a way you can attach a modifier to the actual stop function itself, but bypass most certainly.
Band I'm in does mostly U2, and one song we play is Magnificent.
For that song I have scene 1 setup where I capture the first bar with the looper. I then play on top of the repeats for a couple measures.
I then go to scene 2 for the next part while the looper continues with it's part. So looper NOT bypassed in that transition to Scene 2.
From there when I go to scene 3, the looper IS bypassed.
Later in the song I have to go back to Scene 2, however this time the looper IS bypassed because I control the bypass state of the looper with the control switch modifiers.
So to simplify, Scene 1 has the Looper engaged (not bypassed), Scene 3 has the looper bypassed, and Scene 2 leaves the looper bypass in the same state as the scene you are coming from. (hopefully that makes sense)
Using FM9 Edit I do that by selecting the looper, right clicking the bypass button and assigning control switch 1 as the modifier
Then I go to Controllers->CS Per Scene and set the scenes for "CS1"
To get the behavior I described above, in the CS1 Column you would do the following settings
Scene 1 "Off" <-- a little confusing because off in this case means NOT bypassed
Scene 2 "Last" <-- means you are set to whatever the setting was on the scene you are coming from
Scene 3 "On" <-- Again a little confusing because in the case on means "bypassed"
The on and off is a little counterintuative when used as the modifier for whether a block is bypassed or not but makes sense when used with other properties.
I use the looper on two longs we play live and am getting ready to add a 3rd. Love the loop on the fractal. The loop quantize and record threshold features work great!
