Changing the Algorithm on the Boss VF-1 Multi Effects Device

The used algorithm of the Boss VF-1 Multi Effects Device cannot be changed! What you must do is selecting an already available patch which uses the desired algorithm.

The algorithms are stored in the factory preset bank "B" beginning with Guitar Multi 1 in PB1 and ending with Delay+Chorus in PB36.

And this of course means that e.g. your tastefully adjusted reverb gets lost!
