Re: Clock Divider ideas
1999-05-26 by Dave Bradley
As usual, I have to chime in and ask for weird stuff... How about the ability to divide by non binary values - divide by 3, 5, 7 etc. gives you the ability to set up and/or sequence poly rhythms easily. (Ducking) Dave Bradley Principal Software Engineer Engineering Animation, Inc. daveb@...
