Hi Will,

I exported my first Synthesizer with the AU Button and compiled the files in XCODE. Logic accepts the PlugIn but sees it as effect not as instrument. So there is no way to play the synth. Do you know, how to change this from effect to instrument ??

regards

Peter

Hi Peter

Yes, the Make AU (and AU Template generator) only makes effects plug-ins. I am in the process of adding functionality to make synth plug-ins as well. VST is already finished but not released and AU is in development. Basically you have to derive the plug-in from AUInstrumentBase rather than AUEffectBase but you will also need to trap MIDI events. If you want to try working on this on your own, check out

and

Otherwise, I will let you know when a new version is ready (if you want to Beta test, use the Contact form and send me your email address and I will add you to the beta tester list). Making the instrument plugins in VST and AU isn't much more difficult than effects but there are more details to deal with and I have to do a lot of testing before a release of this stuff.
