I wrote something along the lines of the following (I've added the AU type
constants):
At the moment I have all AUs listed in a single tree by category:
Instruments > Manufacturer (kAudioUnitType_MusicDevice)
Instrument/Effects > Manufacturer (kAudioUnitType_MusicEffect)
Effects > Manufacturer (kAudioUnitType_Effect)
Generators > Manufacturer ( kAudioUnitType_Generator)
Panners > Manufacturer ( kAudioUnitType_Panner )
A lot of the confusion seems to stem from this:
Instrument/Effects > Manufacturer (kAudioUnitType_MusicEffect)
I take kAudioUnitType_MusicEffect to be ambigous about being an Instrument
with audio input, or an Effect with MIDI input, but Sophia Poirier wrote off
list:
Actually it is not supposed to ever mean "instrument which takes audio
input", just "effect that takes MIDI input". I remember asking once about
it long time back on the CoreAudio email list and being told this by Apple
folks. So my thoughts are that something like "MIDI-controlled effect"
might be a less confusing label, in my opinion.
Can anyone else confirm this please? Is anyone using
kAudioUnitType_MusicEffect for "instrument which takes audio input".
Otherwise I will just put kAudioUnitType_MusicEffect plugins in my Effects
category and delete the "Instrument/Effects" category from my UI entirely.
Thanks!
Unlike some hosts, all AUs are available in the same list (ie context
doesn't provide implicit filtering to only instruments/only effects, etc).
Some of my users are finding this classification confusing. I suspect this
is largely because the whole Instruments, Instrument/Effects, Effects
classification is artificially based on i/o topology rather than
functional
role -- so you can end up with variants of the same AU in different
categories (e.g. what the user expects to be an instrument is in
Instrument/Effects for example).
I'm considering removing the top level categories entirely and listing all
AUs only by manufacturer, or flipping the hierarchy thus:
Manufacturer > Instruments
Manufacturer > Instrument / Effects
Manufacturer > Effects
Manufacturer > Generators
Manufacturer > Panners
Is there a recommended Apple way of representing the AU list?
Thanks
Ross.
