I suffered badly from stuck note syndrome some time ago and ultimately discovered that the problem wasn't with my MIDI gear or software at all but rather the culpret was a cheap USB hub. Whenever there was qwerty keyboard or mouse action (both USB through that hub), the hub would get overloaded and ...

Actually, I just bought v6... haven't installed it yet. I wanted to finish the job I started before changing ANYTHING. Now that job's done, I have time to futz with the system. I also ordered a FireWire PCI card... figuring it will give me my ports in a more native way, w/o being a firewire-to-firew...

Generally, you want the most signal you can get (but not clipped/distorted) at every stage of your system. So, where to begin? Start at the signal sources. Anything with a VU/Level meter should be showing you near 0db. If they're low, turn 'em up. If they're high, turn 'em down. Do this starting wit...

Please understand before we go any further who I am and what I know... I'm a long-time MIDI musician who is self-taught in all things recording. I'm a professional software engineer by day, so I know a thing or two about a thing or two, but I'm not a MacOS expert by any measure. Indeed, as a computi...

From what I gather, there is no one true cause of such problems... as many people have found fixes many different ways, be they phantom entries in audio/MIDI setup, corrupted configurations, second rate hubs, or software bugs in OS-X or DP. I get the feeling that the OS-X and DP bugs are now gone --...

So I talked to a friend about my troubles and he suggested something so totally obvious I didn't think to try: my USB hub. I removed the hub (a perfectly ordinary powered USB 2.0 hub, GE-branded) from my system and I haven't had a stuck note or a MIDI glitch for hours and hours of use over the cours...

BjornIn, Check the battery in your MTP AV Reset your MTP AV and reconfigure it. Be sure to follow the manual. I've tried reset & reconfigure of the MTP/AV before... didn't help then. As for a battery, I can certainly check that - but I must say that have my doubts: the thing is always on and is ...

So after my last post, I sat back down to play, frustrated by the whole thing anyway, and blamo, the stuck notes stopped, the on-patch-change soundings stopped, and the bank 0 patches were accessible via program-change. So it comes and goes - and these three things seem to be related. That's informa...

Bloody hell, my stuck notes (and random soundings on patch changes) ARE BACK! I noticed something else very interesting.. the patch change does not work for bank 0 of my Kurzweil 2600R... well, rarely it does, but mostly it does not. All the other banks are fine. I even found the midinam XML file wi...

Well, UN crashed horribly before I could print out your "hardcore uninstall" directions, so I tried it from memory :) I also uninstalled and reinstalled my MTP/AV driver, my 828 driver, and re-built my MIDI setup in AudioMidi just to be sure. Looks like it worked! I'm getting MUCH better p...

Ah - I do not have 5.0 - I got what appears to be a full 5.11 installation CD (with key code and all) directly from MOTU as my upgrade from 4.6. Should be fine to install fresh with that, methinks.

Fodo - thanks much for the hardcore details. Half the battle is knowing where to find stuff! I'll give this a try tonight. I'm thinking I'll want to zorch my 828 drivers, too, as the attendant applications seem to be confused. Seriously - thank you (and others!) so much for your continued assistance...

>It seems worth it to trace the problem-- --indeed. >Turn Local to OFF and route all of your MIDI through DP. My kb has been in local off mode for 10 years :) MIDI thru is not connected from my input kb. I do have one of my MTP/AV output buses chained in/thru/in/thru/in/trhu for some single-channel ...

I'm using a MOTU MTP/AV interface and my trusty Yamaha P200 as my performance controller - the exact same hardware that was working absolutely fabulously on my G4 with DP 2 and 3 under OS 9.2. I've not had satisfactory results with OSX yet, wiith DP4.5 through 5.11 on my dual G5. This is what gets m...

So... today I installed DP 5.11 and the latest USB MIDI drivers from MOTU.

Verdict: still get stuck notes!

*expletive*

At this point, I'm really starting to seriously consider switching to another package . . . despite my decade-plus investment in DP.
