Hi!
The dynamic 3D has the same Midi features as MS PRO does have. Audio recording is at 16 bit, 44,1 kHz, PRO at 18 bit, 48kHz. Dynamic 3D has no digital I/O.
Disadvantages? Hmmm.... I didnīt find out any (except the -3dB truoble of the digital board of the PRO version).
Compatibility? Well, should work with all sequencers which can accept WIN 95/98 soundcards.
I work with Home-Studio 1 and Home- Studio PRO (2 PCīs) and the sequencers from Emagic (Logic), Yamaha (XG-Works),
Steinberg (VST) and Voyetra (Digital Orch. PRO) without any trouble.
Ciao
