Hi Ross, You were right about the number of faders with the Delta 1010 - I checked in the studio, and I only see HW In 1-8, PCM Out 1-8 and the two S/PDIF faders. Two rows would do, or maybe three if you put the S/PDIF faders in line with channels 1 and 2. Then you could specify how many rows and how many channels you wanted... Has this patch been considered for inclusion in the official ALSA envy24 control source release? Cheers Daniel
