I am having a similar problem.
If you have in your block of FX the following - delay, chorus, dist, and reverb.
With regard to assigning these FX to footswitches(FS). Can you assign the one Effect to multiple FS or can only assign the FX to one FS?
for example can you say.
FS1 dist, FS2 - dist chorus, FS3 Chorus delay, FS 4 Dist Delay Chorus etc etc.
Thanks
