Slow down MIDI transmisisons
My control surface (A&H Xone:K2) seems to respond badly to being blasted
with note on/off events to turn its LEDs on and off: some of the LEDs
end up in the wrong state. The effect is reproducible using a small
test program using the ALSA API from C, which excludes multi-threading
problems in Starlet and buffer overruns in the ALSA device. The
controller simply doesn't cope well with large numbers of events
arriving in quick succession.
Adding a very small delay seems to completely fix the problem without
causing any noticable flicker.
