Subject: Re: Off-topic - 1v/oct to .98v/oct conversion

From: Cary Roberts <Cary.Roberts@...
Date: 1999-11-03

I don't see why I need gain. A MIDI to CV converter (ala MPU101) can
only spit out 1v/oct. That means the Multimoog which has a response
of .98v/oct would be sharp when played from a 1v/oct source. Right?
If this is correct, what type of resistor network do I need to come
up with that will give me a very tight tolerance? A simple votage
divider probably won't be accurate enough. Any suggestions?
