I don't know if it is just my machine, I did a search and I don't see any known issues with stuck notes in Diva, but I've been experiencing them chronically. It could be my midi controllers but it really seems to be isolated to just Diva (or I'm using Diva way more than any other synth

). Anyhow I'm just trying to narrow down what it could be. Is there a 'all notes off' in Diva that I'm not seeing? I'm using Reaper, with an Oxygen8 and m-audio keystation both going through a Midisport 2x2.

Same here, in Zebra but not yet in Diva or ACE.

Chen I say 'chronically' I should qualify that: it doesn't happen all the time, just often enough to be annoying, and when it is happening it seems to happen in bursts. Anyhow, I don't have a lot of trust in my midi gear, and I haven't heard it while playing back midi in a mix, just trying to figure out what is going on.

You shouldn't put your notes there, other things go in there. I guess each man to his own.

Harhar! I had to read that a couple times before I found it funny

I have a feeling it isn't Diva's bug but because of the way Diva handles voices it shows up in Diva where other plugins don't display this issue. I believe it has something to do with buffering. In Reaper I changed the media buffering size from 1200 to 1600 (I really don't understand the tech but hey) and it seems to have gone away. I don't know if could be considered a bug in either Reaper or Diva but after making the change I don't see any performance change in Reaper except that the issue seems to have disappeared. I played fast and furious and no stuck notes

so yay!

Hmmm... we know of an issue that seems to mainly affect the Windows build of Diva. Which will be fixed with the version we're releasing after Musikmesse.

The bug can sometimes on some systems lead to voices being silenced, and they won't come back unless the instance is completely reloaded.

I don't know of any issue related to buffer size. I can imagine however that fast play (really fast) can fill the buffer for MIDI events up. In that case, smaller buffers empty the buffer more often, thus it doesn't get too full.

In general our stuff doesn't need more cpu if used with as low as 64 samples or 500+ sample buffer sizes. Internally we're slicing the buffer in pieces of 64 samples anyway. Only smaller sizes, e.g. 32 samples can significantly add a performance drain. Not worth half a millisecond of latency less.

That's all admittedly way over my head

but I got the idea of increasing the media buffering size here where someone mentioned increasing it resolved their issue:

http://forum.cockos.com/showthread.php?t=18270

I normally don't have stuck notes, but found out I easily do when using midi effects(arp-sequencer).

Went into prefs, audio-buffering, jammed the media buffer size from 1200ms to 6000, and now it works.

The problem clearly was overlapping notes, so either I play slow or it sucks. Same problem happened in Energy xt.

I'll test more tomorrow but at least initially tonight it seemed to be fully resolved.

Diva is by far my very favorite lead instrument, the Strumpet patch with a tiny bit of tweaking for my personal playing is heavenly

stuck notes get in the way very quickly of the buttery goodness. But if it is the right note it can actually be cool, like a drone

@braj:
I use to have M-Audio Oxygen8 too, and it had stuck notes with Zebra, and some other synths too.
I bought an Axiom and never had another stuck note again, in any synth.
It's the controller.
Make sure your driver is up to date though, and consider getting the Axiom model. Never had any trouble with it, unlike the Oxygen8, which was a terrible controller, and doesn't have aftertouch either, as well as lame action.

Oh wonderful, just what I need! It's gonna be months and months before I can afford a new decent controller. Both my keyboards have launched stuck notes, both are m-audio models with the latest drivers. They are going through the 2x2 midisport though and that whole chain maybe I need to try and debug. M-audio's drivers in my experience are terrible so rechecking that may help resolve it. I went through the midisport to bypass using those O8 drivers. Hopefully the buffer fix and the upcoming Diva update will resolve it though. I do have seemingly 'dead notes' also on occasion, but I'm not sure if that is my hands, which are not exactly under my control and usually in pain, not hitting the keys hard enough. If I do need another controller, I'd like to get one 61 key controller or larger that can do splits and has lost of knobs and sliders. I think back on all the nice keyboards I've had in the past and have to kick myself a little for parting with them, thinking I'd moved on from making music. Anyhow, if you have any economy-priced suggestions I'm up for them. If its not one thing its another... I did have a dream the other night that I got a fancy 'Diva' controller that had plug-in modules just like the ones in the plugin, you could swap them out as you liked and they would automatically remap to the appropriate filter etc in Diva, as if the controller were an actual analog VCO etc.

I was slightly bummed to wake up

Well still getting some stuck notes, but they seem harder to trigger, I increased the buffer in Reaper to 2000 and getting even less stuck notes. It is not a huge problem now. One thing: if I play a six-fingered chord it will un-stick the note, in case that is a clue as to what is getting stuck where.

You could try the Poly2 mode. If you play the same note as a stuck one, it should "unlock" it. I think. Not sure. Might need to try that...

Thanks Urs, it is happily getting really hard to trigger, once it happens again I'll try Poly2, but it happening 'chronically' seems to have abated. I really don't know what that media buffer setting has to do with midi notes, but it seems to have helped, whether it is a placebo or not I dunno, but I'm playing crazy arpeggios till my arms are sore and not seeing problems.

I'll try with my Axiom49 and see. Now it happens with Zebra only and Novation 25SL MKII and in order to stop the note I need to change preset. It seems to be random but I will try to narrow down to the best I can.
