< You mentioned Wendy (?) Carlos in a previous msg. Was this a slip or wa < this the wife of the well-known synthesiser-master Walter Carlos who di < the sound-track for "Clock-Work Orange " ? Riddle, she is his own sister and self. < Somewhat more back on topic , Megan let slip that you designed an inter < for the "Mark 11". Would it a major undertaking to build an A-D converte No that was the PDP-11. I wouldn't know a mark-11 from a brick. < take the VCO off an analogue synth and convert it to MIDI or to sample o < record it ? And my ST is over 10 years old !! : ^ )) Seems the hard way was as most PCs with sound record can do that. The problem of doing straight A/d is the host computer has to be fast enough to support 22,000 or greater samples a second and enough memory to store it all. Midi is not fast enough to sample/reproduce straight a/d or d/a sound wich is why all midi devices that are reproducers are self contained. Allison
