Hi

I applied the bank_offset.patch and the revised select command works 
effectively for choosing presets from the first soundfont loaded to  
replace any specific preset from the second soundfont loaded. Thanks! 
This is a very useful feature indeed.

(Just one very minor point: the first soundfont still loads with an ID 
of 0.)

loaded SoundFont has ID 0
