I am having trouble creating a pluggo plugin which registers as a mono-to-quad RTAS plugin in Pro Tools HD 7.1. It will only appear as a Quad-to-Quad plugin, and channels 2, 3, and 4 are discarded at the input end. My MAX/MSP patch is roughly this:

...hopefully that looks right on your screen. It is essentially a 1-in, 4-out plugin using [plugin~ 1] and [plugout~ 1 2 3 4] but PTHD 7.1 sees it only as 4-in 4-out.

It passes signal but is somewhat useless as I need it to process mono audio tracks in PT and give a quad output and PT will not implement it into a mono track as it is not aknowleging that my plugin takes 1 channel input.

1. Why is my 1-in, 4-out plugin showing up as 4-in 4-out in PTHD 7.1

2. If I am doing something wrong, what might I be doing wrong?

3. Could this be a bug/unimplemented feature?

So in summary:

2. If I am doing something wrong, what might I be doing wrong?
3. Could this be a bug/unimplemented feature?

My version of Max/MSP is 4.6.2. 
My version of Pluggo Runtime is 3.6


Digidesign's RTAS plug-in architecture does not support a different 

number of inputs and outputs - they must be the same.

TDM plugs can do what you want, but Pluggo does not support the TDM

RTAS does indeed support different in/out channel numbers. For example, one can instantiate a mono->stereo version of RTAS D-verb on a mono track and it will automatically convert the track's output to stereo.

I have successfully made a 1-in 2-out (mono->stereo) RTAS pluggo plugin in Max/MSP and it registers fine in PTHD 7.1, however a 1-in 4-out pluggo plugin will not register as (mono->quad). It registers as (quad->quad) only.

Thanks for the info, you've saved me a lot of trouble.

You can still make a 4-in 4-out plug and use bussing or multitrack audio files.
