No... I mean the Roland FC-7 seven switch pedal.

The problem with MIDI pedals is, so little of the arranger's OS is selectable via MIDI. At least with Roland's. For instance, the BK-9 can select over thirty different functions with the simple switches, but MIDI can address a mere ten or so of them. And most of them pertain to the simple selection of style divisions. More complex functions like ABASS/Man. Bass and stuff like that doesn't have any MIDI hooks into it.

This is also why the iPad apps can do little more than duplicate front panel commands... most of the good stuff you want to get at has no MIDI address, but simply resides as OS commands deep down in the menu structure.

Possibly Yamaha's have a far greater list of things you can get at, but it also means jacking around with sys-ex, as I understand that that is used for most things via MIDI. This is all well and good until you need to deal with a variable (say for instance Reverb Hall Size), rather than a switch function, as checksums need calculating, etc..
