Regarding mapping more than 12 effects: yes, you can do this, using the labels in the Effects section on the MIDI window. There are a few threads about this on the forum. If you can't find a discussion, or figure it out, let me know (hint: B = bank, P = preset, and B2 = the next bank from the currently selected bank). Regarding saving effects to channels: no, that's not possible yet. You'll have to add some other control to map the A/B/Mid./etc area. I'm thinking of changing the order of that MIDI section so that you'd be able to trigger it with a single command - but it's somethig I haven't tried, or planned for, yet. Either that, or I might add a save/load with channel option to each preset.... Regarding ejecting effects: no, that's not possible yet either - though, you can set up an "empty" effect preset, and trigger that on the deck.
