jez, you're right, but only if the keyboard cv & buffer are behaving
themselves. otherwise, dustin could get the synth in a right mess &
maybe even wreck the trimmers... I have seen this happen to prodigies
& rogues where the real problem was the keyboard connections...
first thing to do, as part of the warming up process, is make sure
that the tuning errors are not varying in a way that suggests a bigger
problem.
