Hz shouldn't be the only possible way, but it should be definately possible.
what if you e.g. use a note from a synthesizer as an LFO or something? then
Hz would be appropriate again.
other than that: for notes i'd recommend 4 ways to get every need covered:
a) frequency
b) cent offset + a general base frequency
c) ratio + a general base frequency
d) note number (retuneable to some value of a, b or c)
the tuning standard should accept .scl files (see scala tuning standard:
http://www.huygens-fokker.org/scala/scl_format.html). note that in the scala
tuning standard, there is NO base frequency specified for good reasons. so
the synth must have some method to adjust that (preferably dynamic at
playtime with welldefined semantics for already playing notes).
greetings,
fabb
