The dreaded stuck and dropped notes problem revisited

[Nibiru]

in searching for a solution to my problem, I found this thread.

http://www.motunation.com/forum/viewtop ... =1&t=47621" onclick="window.open(this.href);return false;"

please forgive me for reviving this, but it's a problem for me and I'm on a MBP 2.6,10.6.8., DP 7.24, running an old MTP/AV USB triggering 3 outboard synths.

I don't think it's exclusively a Lion issue.

I'm working on a song that was made in 02', on which ever version of DP was current then. It's all MIDI, no audio. I'm getting stuck and dropped notes seemingly randomly. I don't have this problem when using my M-Audio Keystation USB controller to play VI's. I almost never have dropped notes or playback issues when triggering VI's, or at least so seldom I can barely remember.

Could it be the MTP/AV? I've tried resetting it, and the batteries are new. I have all the new MIDI drivers as well.

edit: It's not the MTP/AV. Said song works fine on my old G5 PPC running Tiger and DP 7.22.

This is so frustrating, any help is greatly appreciated!

I think it is...

I've never heard of anyone using DP 7.24 / SL having stuck notes problems anymore, including myself.

At least you can forget about DP in your troubleshooting, me thinks.
If it annoys you so much, would you consider going back to SL on a temporary HD in the mean time, so you can actually get some work done?

Have you done all the usual troubleshooting steps?

Well, my experience is extremely specific, but it still remains, FWIW:

Thanks for the reply,

however, I'm not on Lion, and never said that I was. I've done all the usual troubleshooting I would normally do, i.e., trash prefs, resinstall the MIDI drivers, etc. I tried turning off MAS and running only MIDI. No dice either. This one is stumping me hard...

Shooting in the dark, Nibiru:
Did you tried to run Audio MIDI Setup in 32bits?
Option to do so shows in AMS Get Info.

[Nibiru]

thanks for the reply Daniel!

I just checked, yes, its in 32 bit mode.

I haven't used my outboard gear in quite a while, so I'm not sure when this mess started to happen. Why it happens on my MBP running SL and not on my old G5 running Tiger is beyond me.

I've tried going into ClockWorks and muting various parameters but with no luck. Tried different projects that also utilize the same outboard synths, I get the same ill results.

[daniel.sneed]

Shooting in the dark again:
- disable Master in Command window
- try various combinations of DP input filter
- try various combination of DP MIDI preferences
- try another MIDI interface (my Motu Fastlane has various issues with 10.6.8, but all is fine with 10.4.11, and my Tascam us-144 interface is fine with both OS)

[Nibiru]

Thanks again Dan. I'll give it all a shot right now!

Edit: I should make clear that the stuck and dropped notes are happening from recorded MIDI tracks. Not so much on record enabled tracks.

[Nibiru]

Um, I really hope it's not me but...

When I go to the View Filter, select everything except "Normal (display/play)", (which basically makes all MIDI data invisible), I play back the sequence...NO STUCK NOTES. I've tried this now at least 20 times. I turn the "Normal (display/play)" button, like clockwork (pun intended), STUCK NOTES.

...Frodo?

Good god, this is beyond my knowledge and I hate that.

Edit: Scratch all that. Stuck notes. Omg.

It seems to trigger a high "G" note on one synth quite often.

Interesting...

The settings of the VF are All, All Except, and Only. Do you mean that if you check the second or third boxes then your problems disappear, and the moment you check the first one they come back?

If so, what CCs are you using, exactly?

Now, the VF only prevents DP from showing whatever you filter (but it still plays them), so I think it's interesting that the mere fact of showing/hiding them messes/fixes your stuck notes

What happens if you make dedicated tracks with different MIDI channels for CCs only? Not fun, but easy to make and worth the try..

Yes. Although, it did just happen even tho I had "Normal" unchecked. It was pretty stable when I had "Normal" unchecked VS checked. Stranger than strange...stumped.

Nibiru... you are aware of a no politics policy on this board. What is your avatar supposed to mean? It may really be skirting this policy.

Hi James,

I've been posting with this avatar for a while now. In fact, in threads that you were a part of. I didn't realize it was, and certainly wasn't trying, to be politcal. It's a Banksy image that I came across and figured I'd use it, as most musicians I've known to be all for peace. Just tought it'd be ok I guess. I can change it if you'd like me to. No worries at all.

[Nibiru]

As for the my stuck note extravaganza...

I followed Dan's advice and went out and bought a new USB MIDI interface. An M-Audio MidiSport 4x4, just as a temp until I figured out what the deal was.

No more dropped or stuck notes.

THANK YOU DAN!!! I really appreciate your help and insight!

So it must have something to do with the drivers and my older than dirt MTP/AV USB unit.

Anyone any ideas?

[Frodo]

I don't think it's exclusively a Lion issue.

I think it is...

I wish I could agree-- but it's not exclusively Lion. I'm running 10.6.8 with 7.24 and just today had a massive stuck note issue that sent me back to 5.13 and 10.4.11 to finish the project. There are only two MIDI tracks in the project, so it's not a big project at all. The stuck notes happen in the same place, around measure 10. That's where I gave up on it. It's not just this particular project. I "back-save" the projects to run them in 5.13 and all is well, but I'd really like to get 7.24 into full production at long last.

I've never heard of anyone using DP 7.24 / SL having stuck notes problems anymore, including myself.

You, my friend, are blessed!

However, I do plan to rebuild all of my bundles and templates, dump prefs, and even reinstall VIs and DP 7.24 if necessary. I spent the morning updating all of my VIs and am about ready to just wipe the 10.6.8 drive to start entirely from scratch.

I know that the issue is not widespread, but it feels like a bad cold that just won't go away.

I wish it were as simple as getting a new MTPAV, but I did that a couple of years ago thinking it was the culprit. Works fine in Tiger. But in my case would it really be the MTPAV if the notes stick on playback? Does anyone know if the MIDI driver/interface is involved with playback if it's all ITB?

This is going to take quite a bit of mental floss to tweeze through the troubleshooting.
