Marc,
Thanks for the comments - I think I'll include both yours and Urs
examples as usage scenarios :)

What led to the decision to keep MidiNotes away from MusicEffects? -
I think that Midi Notes are actually a grewat way to manipulate
Effects that extend synthesis. Like Filters with Note-controlled
Cutoff frequency. And there's a common way to circumvent lousy
problems by calling a distinct method of synthesis "Comb Filter"
instead of "Physical Modelling". Hence building a Gate/Delay/Filter
MusicEffect would be great to have in an effect chain...
We want to distinguish between a Music Effect - that essentially
provides for this "run time" mapping of "controllers" to the rendering
process, and the concept of creating notes that are then controlled
(which is the domain of the Music Device unit).
I take your point though - using the MIDI note messages as a way to
manipulate some parameters seems like a legitimate usage - but what we
don't want to see is the use of Music Effects to actually generate
notes per se... Maybe we're being more restrictive than we need to be
here...
I would say "yeah" to that, too. I don't see any reason to make a hard
line restriction like that. I think that all that's necessary is an
explanation in the docs like the one you just gave above.
I for one have made plenty of effects that are are definitely not note
driven, but benefit a lot from MIDI notes. Like, for example, Buffer
Override and Scrubby. With BO, you can optionally use MIDI notes and
pitchbend to adjust the divisor parameter. That parameter will then be
changed to the value that makes the sound stutter at the rate of the
note's pitch. With Scrubby, playback of the audio buffer speeds up and
slows down randomly. You can play MIDI notes and then Scrubby will
constrain the speeds to ones that transpose according to the notes you
play (within one octave). So you see, these are still very much
effects,
and do everything that they do without MIDI notes, but they are much
more
musically usable and fun with MIDI notes. So anyway, just thought I'd
give a couple of examples for you...
Marc
