We never used this on our CDs that came out cept bte5 aka oblivion interface. We did use it on some really old demo material! It was okay for its day, but the emax killed it hands down. It was affordable. But 12 voices 32khz 12 bit. Has an agressive sound to it that gear today cannot create. Very cool if you like old gear. Interface is ok, but storage is a pain. This was a our main synth when it was grig and i in 1992.
