This way my clean signal goes through the hardware to the PA with no latency (or at least a fairly un-noticeable latency), then the processed signal/s get overlapped with the minimum latency I can get.<br>
This is the cheapest and more satisfying workaround I found so far, even though it's not reliable in every condition and setup.<br><br>Besides, as already said, when you trigger digital effects with an external hardware you can add more latency; to avoid it, I analyze the un-processed input signal, recognize the notes being played and trigger effects when a note is recognized.<br>
Thus I just deal with the latency created while the un-processed input reach the analysis patch. <br>At the same time I route the un-processed signal to the effects bank.<br>Not rocket science but hope this helps.<br><br>
