Anyone else have general issues with GarageBand?

Also have a look at this thread:

processBlock not being called for generative plugin

I can’t seem to find the forum post anymore (the post had an odd title), but the conclusion is that Logic will stop calling processBlock after a while. This is just a limitation of Logic that you will have to live with.

Basically, Logic (& GarageBand) will not call your processBlock function if the transport is not playing. Only exception is if your plug-in is a synth and Logic detects midi coming in.
