Default Instrument tracks greyed out/no sound after reopening session

This has been going on a pretty long while for me, and on three different computers during several different versions of Pro Tools.

Sometimes when I re-open a session, one of the instrument tracks will output no sound, and the clips on that track are all grey. The plug-in is there, and it looks like it should be passing audio, but it's not.

Normally just duplicating the whole track (with inserts) and then deleting the original one fixes the issue. But it's annoying... More than once I've revisited a mix trying to figure out why it doesn't sound as full as it should, only to discover a dead instrument track.

Most VI's I use are Native Instrument plugins (Kontakt, Battery, Massive)…but I think this happens with other VI's as well.

Anyone else experience this? Any known solutions?

If it's GREYED OUT, then your IO or INTERFACE has changed. Check IO first and correct it. Also, check the box that says something like "session take priority...".

Default Re: Instrument tracks greyed out/no sound after reopening session

I don't think so. It happens randomly, and it's always just one instrument track. Most of my sessions have at least 5 or 6 instrument tracks, often more.

Maybe "greyed out" isn't how I should have worded it. The track all looks normal (no italics or anything), but the clips are grey and no audio passes through.

And like I said, merely duplicating the track always fixes the issue.

You do have me wondering whether this started happening after I switched to my current interface, though. I've had my Metric Halo ULN-2d for at least couple of years...and I can't remember if it was happening before then or not. I feel like it was...but I can't be sure.

often it's a midi channel assignment
that's been made inactive.

view "instrument" in your mix window
and check the midi assign;
sometimes just ctl-clic-ing or
reassigning will snap it back to life...

I've had this happen randomnly in PT10.3.8 with EWQLSO. Been lucky with PT11.1.2 although the Play engine libraries if I'm using more than 1 instrument in an instance will sometimes mute one of the instruments inside Play that gets cleared by cycling mutes or solos inside the Play engine.

Elicious, you were right! I had forgotten that the Instrument info was even a visible thing in the Mixer or Edit window. Happened on a session I opened today, and sure enough the output had been changed to the wrong instrument track.

As to why this is happening, that's still a mystery to me. But at least it's a little more elegant solution than duplicating the track and erasing the old one each time.

Thanks for the help. If anyone has any ideas on the cause of this I'd love to hear 'em.

Hello. I know this is an old thread but it is happening to me still.

Same exact problem.

I can re assign the midi instrument to the proper output, but why is this happening?

I can see if you had a project full of VI's it would be a major pain in the @#)$*#@$

Any ideas?

Thank you
