A few months ago I bought the DMX and unfortunately I found some bugs in the driver software. Terratec developed a new driver but still not 100% OK.
The DMX works fine with MIDI but harddisk-recording causes clicks and dropouts.
Last week was one of my 'low tolerance'-type weeks and I decided to remove the card.
Now I purchased the Midiman MAudio Audiophile 2496 card

!
This device has 2 analog INs, 2 Analog OUTs, a coax digital IN and coax digital OUT + midi..... Perfect for me and guess what :
Pure sound without noise, clicks and not a single dropout.
The B4 sounds much better too !!
