Any ideas guys? I'm not even sure the mailing list works...

Cheers!

Hi folks,

I have a really weird issue here. I implemented an AU, using MusicDeviceBase. If the AU has 1 input bus and 1 output bus, it works everywhere. If it has 2 inputs (main and sidechain input), it works too, but not in Digital Performer - it seems working fine, but DP just interprets the output as silence. So it must be some AU buffering problem. I do this in the overriden Render method:

- PullInput for all inputs and retrieve the buffers via GetBufferList
- get output buffers via GetBufferList for the single output
- then just render all the stuff from input to output...

The output buffers are definitely not silent, but DP shows nothing...

Any ideas?

Thanks in advance!
Vojtech
