I am building a multichannel plugin and have come across a strange situation - every configuration from 1-1 to 10-10 works in Pro Tools except 4-4. The plugin does not show up on “Quad” tracks in either Mac or PC versions of Pro Tools.
I have my config set up like this:
#define PLUG_CHANNEL_IO "1-1 2-2 3-3 4-4 5-5 6-6 7-7 8-8 9-9 10-10" #define AAX_TYPE_IDS 'IEF1', 'IEF2', 'IEF3', 'IEF4', 'IEF5', 'IEF6', 'IEF7', 'IEF8', 'IEF9', 'IEFA' #define AAX_TYPE_IDS_AUDIOSUITE 'IEA1', 'IEA2', 'IEA3', 'IEA4', 'IEA5', 'IEA6', 'IEA7', 'IEA8', 'IEA9', 'IEAA'
The plugin works in every track channel count except 4-4 (Quad). I have tried with only “4-4” config (no other configs) and that does not work either. Other plugins show up and work in PT quad tracks so I don’t think this is a PT bug. Seems to be something in iPlug.
I’ve looked at the iPlugAAX_Describe files and I don’t see anything out of sorts. Tried setting some debugging points but nothing comes up. When I checked ParseChannelIOStr after loading the plugin it shows 4in/4out is valid among all the other I/Os.
Any ideas why the plugin does not show up on quad tracks and where to look for the cause?
