Shift + Option + Record Enable not working with MIDI and Audio Track selected, why???

[enzomolinari]

Hi,

Here is my problem:
When I select one or more Midi Tracks and one or more Audio Tracks at the same time and hold shift + option an then press the record enable button on on of the Tracks only all the Audio tracks or all the Midi Tracks are record enabled. So it works with multiple Audio Tracks only or multiple Midi Tracks only but not when I try to arm MIDI and Audio Tracks simultaneously. Why not?

I know that you can select record-enable as a mix attribute within a mix group when using Pro Tools HD9. I have PT9, not HD. So could someone try if it is possible to arm MIDI and Audio Tracks together, when using a mix group with the mix attribute "record enable" instead of selecting them all and holding shift + option while clicking the record enable button.

Thanks
