Re: Considering building an ultimate looper...

Mostly right at the end of the taper where it drops off rapidly.  We 
want it to be flexible for doing live or studio work at a professional 
level and you definitely can tell the difference between 7 bit and 
analog on volume control :-).  I've not done design specifically with 
dsp chips and yes it'll be a bit of a learning curve I understand.  I'm 
pretty versed like I say in the realm of getting all the control stuff 
alligned and I've written midi software in C also in the past btw which 
may help in that realm when we get there.  -bob
