I finally started using the editor this weekend for my MS-60B, which hadn't been used in a long time since the manual can be a little opaque and trying to edit patches with the little knobs can be frustrating. In virtually no time I was able to reconstruct my old rig's sound going straight into an active cab, and with a little more time was able to get a really good sound going through secondary preamp. So much easier than knobs.
But what really hit me is that I'd never fully understood how the pedal function on the MS-60B worked: at one point while I was editing a combo (ZNR+Hartke clone+EQ), I hit the physical pedal to A/B the bypass sound. That's when I saw on the computer screen that only the EQ, which was currently being edited and was therefore showing on the pedal screen, was turned off--everything else in the chain remained active! I had no idea that if you went directly to one of your patches, stomping on the box only turned off the effect showing on the pedal screen!
Naturally that both helps to ensure I'm using the preset list to cycle between a bypass patch and a programmed patch; but it also opens up the possibility of adding an overdrive or chorus to a favorite everyday patch without having to necessarily create an overdriven version of that patch in a different slot. Just page to the effect in the chain and turn it on or off!
Naturally, these are all things the pedal already did, but @Tonlib just kinda subs in for the manual and makes it a lot more intuitive to understand and use. Thanks Denis!
