Voice Stealing

Why does it feel like under the new OS there's a lot of voice stealing happening across many COMBI sounds.
Take COMBI A005 Sweepin'Swooshie Pad for example. With KARMA on and simply chords it's choking like crazy. Voice CPU load is hitting 100% at about 66 notes of Poly.

Sharp.

I am pushing it- 8 notes at a time, drums, karma, full on. I even throw on the sustain for laffs, I can just slightly hit 100%, can't detect serious choking.

i have 'idle ' for smooth sound transition for the Combi. Looks like a default setting

Hmmm. I can make it happen even without KARMA running on select COMBI's

The PCG programming on certain PROG sounds is still wrong also. For example, don't play a note yet. First select PROG U-A 064 Clav Register AD and then go the Pref Meter page.

Notice the poly count is at 0. Now play 1 short note. Notice the Poly Meter never goes back to 0, it stays at 1. The more short notes you play, the higher and higher the poly count will clime. You can get to a point where no notes are even heard and the voice stealing is kicking in.

Your right. Combi A005 did the same for me. Very easy to max out the polyphony. I don't usually use these types of sound so I don't know what it did before the update. I have no frame of reference. But I see what you mean when you go into the cpu and voice stealing screen. Very easy to overload.

Hmm, that's a bit worrying. I was just about to install the new OS but now I'm not so sure.....

With U-A 064 I got the Poly Meter up to 140-150 - the meter DOES drop back to zero, but it takes around 12-13 seconds after I stop playing to do so. All of that group of clav patches exhibit the same behaviour.
Strangely, with the combi you mentioned I didn't get it to choke...

They shouldn't do that though. Anything that eats up the poly when no sound is being produced is not right. It's actually caused by a wrong parameters set in each sound. I know what to adjust so I can fix this for my KRONOS and I will replace my PRELOAD.PCG

Hi Sharp,

What is the parameter?

Cheers

No, obviously it's not correct behaviour. What are you doing to fix it?

yea, I'm with you. I think I'm going to hold on upgrading mine for a few days.

It's the Time "Slope" value on the "AMP 2 EG" page. It should be set to 0.

As Sharp notes, this is due to a long slope time in the Amp EG. I just checked version 2.1.2, and it works exactly the same way re polyphony. No change there.

Combi A005 is an expensive one. I just tried it on an original KRONOS with version 2.1.2 as well as a new KRONOS with version 3, and it behaved the same: consistent voice stealing (e.g., hold down notes for about ten seconds, waiting until the note-on stealing dies down) starts when playing 7 notes (RH 4, LH 3), with CPU usage centered in the mid-80's and # of voices popping from 60s to high 70s (this Combi includes KARMA and drums, so number of voices varies).

It also uses a lot of EXi, so overall polyphony will be lower. All seems normal to me so far.

Thanks for looking into this one
