So I want to turn a single Trumpet or Sax into a 3 piece Horn section at the gig. Mostly Stabs and staccato lines if you can picture that. My understanding is that most vocal processors will glitch-out if the pitch is too high. Does anybody have any experience with this situation? Could you recommend a pedal or processor that does a decent job for not too much money ($500 or less). I can already add reverb, delay, and slight detune at the board, but I'm looking for octave and possibly intelligent pitch harmony. Ideally it would easily interface with a mic and be foot-switchable... Thanks in advance, Rock on'
