But there's usually some characteristic of the old stuff that becomes very difficult in the new technology. And then you need a few more generations of new technology before you are able to do the old idea again. In this case, you used to be able to easily change the sample clock on A/D and D/A convertors, and they would be happy and nothing else in a simple delay system would get screwed up. Nowadays, the convertors give better audio but don't let you do that sample clock trick anymore, and other things in the system that need accurate timing (like midi) get screwed up. So for the echoplex and jamman, this sort of thing is impossible. So now you need to add a fair amount of dsp processing and more sophisticated real-time os techniques to be able to do what once just required a very cheap part. such is progress.... kim ______________________________________________________________________ Kim Flint | Looper's Delight kflint@annihilist.com | http://www.annihilist.com/loop/loop.html http://www.annihilist.com/ | Loopers-Delight-request@annihilist.com
