For me, I would like to use the Behringer rotary or fader box to control the hdsp driver directly. It seems that your object would be a nice way to do this without tying up the entire midi box. <br><br>I don't understand how the madi works I guess; when you turn up one level, all 8192 values are sent to the driver? Or is this just on startup.

<br>exceeds 16k-limit on ioctl for madi to get it in one call, so it has to make<br>a lot of sytemcalls if also monitoring them. So the goal was to extend the<br>alsadrivers for memory-mapping of faders and additional power and peakmeters
