DP 10.1 undo deletes MIDI data?

[SMS]

• open a project in DP 10.1
• select some MIDI notes
• nudge with arrow keys, or quantize, maybe ANY edit
• CMD-Z then will delete the notes instead of just undoing the edit


anyone else seeing this?

[dix]

Not seeing this here. A key command conflict maybe?

[MIDI Life Crisis]

Here's another possibility... perhaps the cmd-z (UNDO) keystroke is repeating, so you are UNDOing the edit, but then you are UNDOing the recording.

Easy to test. Record. Make several edits and start UNDOing them one at a time.

Does the second one still erase everything? Does it go back two steps only?

[SMS]

Not a key conflict...

The data disappearing was recorded a long time ago.....

Once the data disappears nothing gets it back… No amount of undo or redo.... I have to revert to saved to see the data again

No There is some weird stuff going on.

On a new project Undo/Redo seems fine, but on an older project I'm getting the following weirdness (only using the Edit menu to eliminate a key-command issue while I try to figure it out):

I record two performances on a track (Record > Stop > Record again). Choosing Undo from the Edit menu undoes the second performance, but selecting Redo from the menu erases both performances!

Weirder still, using the Undo History can't bring back the performances either. In fact navigating forward and backwards in the Undo History always erases the performances (no branches involved here. It's just straight forward Undo/ReDo). So if you record three different times, moving back three events erases the performances, but moving forward does not restore them.

I tried Loading the old Chunk to a new Project, but the old Chunk continues to have the problem...Chunks in the same project that were created in 10.1 are fine and Undo/Redo as expected.

Whoa.

I am currently working from copies of old projects only. Keeping 9.52 on separate boot drive just in case.

I just tried both of the scenarios on my setup.
5,1 with 10.13.6 DP 10.1.

Opened new project in 10.1 and undo/redo worked fine on MIDI tracks.
Opened old project created in DP 9 and edited MIDI tracks. No problems.
Recorded additional MIDI in both cases with a Record/Stop/Record/Stop/Record/Stop.
All steps were undoable and the undo history worked as expected.

So far, I can't replicate the problem.
Good news/bad news, I don't know.

Yeah, we've heard this story before. Some people see repeatable problems that others can't reproduce. DP 10.1 seems to take it up a notch in this regard. I'm currently in the middle of a back and forth in a tech link with MOTU. I've installed OS 10.14.6 on a virgin drive and DP 10.1 - nothing else. I still see the problem and MOTU can't reproduce it at their end. I can reproduce the problem on three different machines (two different OS). What the heck is that?

I'm thinking of taking a drive to Cambridge with my laptop and say, "Here guys. Have at it."

I can't replicate this.

Well, so far this behavior is only occurring on certain Chunks in one Project for me. I've opened other Projects including pre 10.1 and Projects started in 9.52 and so far the issue is limited to the one Project - It happens to be the Project I need to work on currently, but whatever

I tried flushing the Undo History to no affect. It only happens with MIDI recordings, not audio, which leads me to think it's a Retrospective MIDI anomaly. The only workaround I've found is to duplicate the take I'm recording to a bunch of times and be very conscious of every Undo. If I hit Undo multiple times the MIDI in the duplicated tracks (though not the tracks themselves) starts to disappear permanently.

more testing reveals:

• as reported above (thanks!), only affects chunks created in an earlier version

• a new track created by dragging a problem track into a new sequence will still have the problem

• copying the data in the track to a new track in a new sequence cures the problem


MOTU is aware, and working on a fix

I just noticed that this behavior is only occurs on Locked MIDI tracks. I tested this on a few Chunks in different projects. Whenever the track is Locked Undo>Redo>Undo erases MIDI permanently. When not Locked Undo/Redo behaves normally.

So it looks like I have a pretty simple workaround. I'd be curious if those that are experiencing this can duplicate the workaround, and those that are not experiencing it can make the bug happen by Locking the MIDI track.

Yes. My tracks were locked in the problem sequence. Thanks for discovering (and reporting!) this. Pretty easy fix.

Yes, I can make it happen with tracks locked. You've reported it to MOTU?

I wanted to be sure others were able to make it happen. Reporting now.
