@nielso @_slotek_ Sorry to hear that. #Latency is surely an issue with low frequencies. There will always be a perceptible delay which becomes uncomfortable above 30ms but won't go below that either because of algorithmic latency + ADC latency. Is there less latency on higher strings?
Since it all comes down to algorithms, someday a new one might arrive to solve all our big-buffer problems in the low range ;) That's why I'd go #Cycfi rather than #Roland because of updateability of the actual part that tracks the pitch.
