Received my Boss FS-6 footswitch today along with 10m of VanDamme 2 core multicor to make up a twin jack to jack with Neutrik ends :-)
Hooked it up tonight to test and play with footswitch operation and there's an issue I hadn't anticipated...
My plan was to use footswitch A to mute the FX using the assignment FX Mute set to Momentary... This works flawlessly.
The second part of my plan involved setting up two "scenes" and using footswitch B to alternate between the two. Scene 1 has the M20d ready for gig, ie all channels unmuted (except iPod/Menia) and scene 2 has all gig channels muted with iPod and Media unmuted. The idea: Soundcheck. Set background music to play using iPod/iPad over airplay through apple router. As we're about to start playing, press footswitch to mute iPad and open up the gig/band channels. As we finish the first set, press footswitch again to revert to background music from iPad. Ditto at start of 2nd set: footswitch to flip from iPad to band, then finally flip from band to iPad after finishing. Doing this, I haven't to worry about stopping the background music, it can just play on into a muted channel.
So I set up two scenes... flipped the footswitch and it correctly jumped to alternative scene... but that's it! It stops there. So now I have to go back to M20d and reset the scene on the screen.So, I set up 5 scenes: background -> set1 -> background 2 -> set2 -> background
OK, that works... but if I inadvertently stomp on the switch once too many and need to flip back I'm out of luck. The scenes have run out and we're stuck on the last one.
What would make more sense was if the scenes list automatically reset itself to the beginning on the next stomp if the end scene has been reached... that way, 2 scenes, and it just alternates. Would be nice to think that this relatively simple extra option might make it into next firmware release.
