...patches and firmware, sure and makes sense. However, from the manual: The M13 will send and receive MIDI CC and Program Change messages on any MIDI Channel from 1 thru 16 or Omni...
If it's going to send MIDI messages, as the manual states, I think it's reasonable to expect that with today's technology, it would be rather instant. Additionally, from what I can tell, aside from your response (which I do appreciate by the way), Line 6 has been rather quiet on the subject - no updates for the M13 since Jan 2011, etc. I suspect the M Series is nearing end of life and since there hasn't been an update for over 6 1/2 years I'm not expecting resolution for this issue. For that reason I think it's in my best interest as a consumer to look at competing products - which is a shame as I really, really like the M13, the sounds, the simplicity, etc., but the latency is a real pain to deal with in a live situation.
Thank you for your response.
