You can have two separate stacks, for realtime and non-realtime effects,
and view the non-realtime effects as an explicit undo stack. It could
also include things like copy and paste commands, manual sample point
tweaks etc. I've been thinking about writing a sampler like this (and
got started on it, but other things got in the way).
