- Thread-topic: AudioUnit plugin access to Logic/GB Key Signature timeline information
I only have and am using the Tiger Xcode SDK currently, I had a look at the
documentation there, but it mentions explicitly that it only supports beat
and tempo as below:
OSStatus AUNodeSequenceDest::DispatchGetBeatAndTempo (
void* inHostUserData,
Float64* outCurrentBeat,
Float64* outCurrentTempo)
Is there any chance that further informaiton has been provided for in
Leopard ?.
If not, could such stuff be added ? It would be extremely helpful to me and
Help in promoting OSX as the best sequencer/plugin platform.
