CEM3340 synth tuning question.

[Neville Walker]

I have a Crumar Spirit Monosynth that badly needs its oscillators
calibrated. It has two CEM 3340's and various other CEM VCA and VCF
chips scattered throughout the synth as well. Unfortunately I have been
unable to locate any service docs for this guy at all. So I will have to
resort to some sort of trial and error procedure.

The LFO's also need some sort of adjusment because I get a slight
bleeding of the LFO even when the Mod wheel is turned all the way down.

I have access to a oscilloscope, if necessary, but what I really need is
some guidance as to how to go about tuning the thing.

Some of the trimpots change the pitch of the synth in one octave setting
but not another which is really confusing.

Any suggestions would be much appreciated.

Thanks in advance,
		Nev.
