Latency is variable and depends on pitch. Roland GI-20
needs two periods of
wave to read the frequency, so the worst latency (low E string on guitar) is
about 25ms. Some people replace the low E string (or even all strings) on
their MIDI equipped guitars by high E string and then let MIDI converter or
synth to transpose them into correct values. It allows the lowest possible
latencies.
Hey thanks just the info I needed! Perfect.
