Yes, I've seen this on the Hercules Mk2 as well. I did some work on the
script for it involving a function to turn on/off all LEDs on init,
purely as an "I've just booted" type thing. With no delay between midi
messages for each LED only some would turn on/off so I ended up sticking
in a 10ms pause between messages:
for (LED in HerculesMk2.leds) {
HerculesMk2.setLed(LED,onOff);
// Seems that if midi messages are sent too quickly, leds don't behave
// as expected. A pause rectifies this.
HerculesMk2.pauseScript(10);
}
HerculesMk2.pauseScript = function(ms) {
startDate = new Date();
currentDate = null;
while(currentDate-startDate < ms) currentDate = new Date();
};
This actually make for quite a nice "wave" of LEDs on/off for init eye
cancy but is obviously not what you want to have to do in other
circumstances.
This was discussed a bit in the "Odd happenings with Hercules MK2"
thread, but think it was left as:

Interesting. I'm on Ubuntu Studio 8.10 (Intrepid).

I've not had time to be actively involved in Mixxx of late so have only
been giving the list a cursory glance every now and again, and anyhow,
I'm fine with JS/XML/MIDI etc. but debigging MIDI issues is out of my
sphere.
Cheers,
Jim.
