have you tried the 'Pick' parameter in the AMPLIFIER module?
Yes, no luck! I have bought an EHX Attack Decay which is the best auto-swell pedal I have tried yet, and I'm using it in the effects loop of the Kemper Stage. It works beautifully both in mono and polyphonic mode. It's a pity, because it's the only outboard effect I reckon I'm going to need! It's a pity on two counts (1) it's extra gear to bring to the gig and extra set-up time connecting it to power, audio, etc (2) the Kemper has an effect that sounds like it ought to operate in a similar way but I have been unable to get to work satisfactorily so far.
