I find 65 AudioParameter is not initialized on the first automation recording in Ableton Live.
on 2nd automation recording, it works good.
It works good with 64 parameters.
Ableton Live displays all parameters for up to 64 parameters, but if more than 65, the parameters are displayed dynamically. (Probably displayed parameters will be initialized in Ableton Live)
on prepareToPlay(), I call setValueNotifyingHost(), but it doesn’t work good.
This may be a bug in Ableton Live, but how do you explicitly send initial parameter values?
