No, the Yamaha MFC10 does NOT have a transpose feature. If you wish to transpose “on the fly”, you might look into a MIDI transpose pedal such as from Midi Solutions or try to find an out of production Anatek Pocket Transpose box. If you are using a VL70-m, note that you can transpose individual patches on this synth and easily save them to the Int bank. Info on transposing the VL70-m globally and on a per-patch basis is explained elsewhere in this FAQ. Note that changing the transpose value on the VL70-m DOES NOT alter the MIDI data that passes through it or goes out its MIDI ports. So if you transpose the VL70-m any connected MIDI modules will still be “un-transposed” and will not match its pitch. Note that the older (out of production) Yamaha MFC2 MIDI foot controller DOES feature a transpose function. The (out of production) MFC1 does not. Sometimes used MFC2 pedals are available here.
