I was fine with it personally; there are a few buttons where it would have been nice to have the state represented by the LED, eg EQ kill switches, touch-sensor switch, and the various buttons I was eyeing up using for LADSPA, but I didn't feel it was a major problem. For me, the major problem was that I just didn't enjoy staring at a computer screen while mixing, especially with dilated pupils... so when my Xponent went wrong it was a good excuse to ditch the whole setup and go CDJ. > Is there basically no chance of later LED support without legal > changes at m-audio? It might be possible by reverse engineering. There's precedent for writing a GPL driver by that means (forcedeth) without hitting legal difficulties. > Do LEDs follow local button actions (eg.

(Or maybe on all the time, > nice for night time.) Each button's LED lights up briefly when the button is pressed, then fades out again. This happens within the console (ie nothing to do with the USB/software), and is a feature I particularly liked as it makes it obvious when a button press has registered. But to get any of the LEDs to stay on must require some USB message -- it's not clear whether it's MIDI or not; I tried firing a full sweep of MIDI Note and CC messages at it without apparent success. > I take it the progress meters, etc (eg. all output to Xponent) > do not work... Indeed, and that includes the VU meters as well: they are just LEDs, they don't really monitor the volume (alas). > Howsa trackpad? The mousy joystick on the Herc sucked pharts. It's just about usable as a mouse replacement, but really not great by the standards of most laptop trackpads. I would be inclined to stick with using it as a MIDI x-y controller instead, or at least would be once LADSPA is properly integrated :) Ben ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
