Re: oberheim echoplex for sale

[Bob Weigel <sounddoctorin@imt.net>]

It was a really well done piece for it's day for sure.  I just acquired 
another K5m for my van actually.  Many of my old songs run sounds off 
that...and they're so different nothing else quite captures the aura...

A huge amount of the work in that project was writing look up tables 
that would adequately convert real times to the rather arbitrary 
'rates'.  I built a sampling card for my PC with a 10 bit adc back then 
on an isa proto card :-).  Cheapskate I am, and used that to sample data 
from which to model whatever they'd done.  The engineers were nowhere to 
be found. :So sad nobody knows who worked on machines like that.  It'd 
be cool to have that info for all the synths on my sounddoctorin.com page.

Anyway, those 'rate' values were not a smooth function...and...they were 
interactive so I had to write multi-dimensional lookup tables actually. 
But we got it so one can enter actual time values when they edit the 
envelopes anyway :-)  Seemed important at the time.  Wrote some cool 
sounds with it.  Sold very few copies.  Ads didn't pay for themselves so 
I bagged it. -bob
