Scott,

I have not tested yet.... to be honest I almost NEVER use the musicfinder.
For me the best way is using te registrations - feature.

For example :
I created about 40 reg-blocks (block 1 to 39) with 8 presets each (1-8). In our songbook every song has a few figures written to it that represent : Block# + preset#

Lots of parameters can be stored into the regs : song, style, voice, tempo, transpose, harmony, sounds, HDR, pedal, output, intro, variation, scaling, mic-settings and text.... just tick what you want

Perhaps you should change method of working ?
Believe me it's the easiest/fastest way to change songs (three seconds to swap)
