Dual Delta 1010lt units = 20 in/out
Supports up to 4x internal for 40in/40out
pm sent... I have 2 units only (20in/20out) with Windows 7 x64 drivers. Trades welcome (USB external audio card w/Phantom, digital piano etc)
UPDATE: Original post May 15, 2014 was in reference to a post needing 16+ ins/outs ... I think the modified post no longer applies to trade ko.
