Weird Sustain Pedal Bug

xtatty · Post by **xtatty** » Mon Apr 16, 2012 6:19 pm

Does it ever happen to you where you are playing a lead sound and a note automatically sustains itself even though you weren't touching the sustain pedal?

Once it occurs, it stops only by changing the patch 2 times or switching to a different sound and switch back.
Probably because the Smooth Sound Transition Tech keeps the previous patch sounding.
And it continues doing that with several other patches. The only way to stop it completely is by rebooting.

I tried calibrating the sustain pedal but nothing.
I have 2 sustain pedals, 1 for home and 1 in my gig bug.
My home pedal is the 'Music Store VFP 1/25' and the other is the 'Korg DSH1'. But it happens with both pedals.

I' ve been having it since i bought Kronos with OS v1.0.4.
It continued with the v1.5 update and with v1.5.2 (after the keybed service).
I haven't experienced it yet since the last update (v1.6).
Does anybody else have the some problem even after the update?

(There is a similar post in Karma Lab)

Did you try changing the damper polarity (page 778 Param Guide)?

Yes! It has nothing to do with the polarity.
I use my pedals for quite a long time with Triton Extreme, M3 and now Kronos.
I know how to set them up.

The pedal functions well most of the times.
When the bug occurs it is not sustaining all of the notes (keys) that i press.
It just gets stuck with one note (key) and keeps it sounding for ever, even tough i play other notes (keys) after that!
And it doesn't matter if i press the pedal or not after it stucks.
It is strange because sometimes it gets stuck in lead (monophonic) patches, and although one note is sounding, i can play another one without muting it!

Also sometimes this can occur even if i don't use the sustain pedal at all with the specific patch.

Yes, precisely as you describe it but used to happen on 1.5 too!, using the nanopad2 have seen this happen a lot (and i don't have a sustain pedal on the K, its still hooked to the M3).
Bought recently the Karo EXs54 and after installed there is a 'Global' file in there and loading it helps suppressing the event but donno why or where it lies cause i don't have enough knowledge about the K yet

I use a pair of Korg DSH1 damper pedals, both with the Extreme and the Kronos, with no problems. But because usually I don't kick the sustain pedal with this kind of patches, I may have not noticed the issue...
Can you mention the patches with the problem? Are these factory patches? Are they from AL-1 or other EXi, or from HD-1?

Have you forced the pedal input jack in any way? Although the opposite should happen (sounds cutting off even with the pedal pressed), I'm not sure if bad soldering of the jack on the board could cause this, probably not. Seems a software thing.

It happens even without a pedal!!!! (was just editing my message when you crossposted)

I had this problem once, but only with a user multisample in ram. Rebooted and probelm went away. Hasn't happened since. It's odd with a keyboard. Like a regular computer, when things are weird for no apparent reason sometimes a reboot really is called for with the Kronos!

It occurs even with Orchestral Combis! It doesn't have to be a lead patch necessarily.
I don't recall which where the patches because i thought that the problem was irrelevant with them.
I thought it was a general problem because ones it begins it gets stuck with many patches.
Next time i will write them down and inform the members of the forum.

I have a sustain pedal plugged most of the times. But sometimes it happens when i'm not pressing it.
The truth is that it never happened the times that i hadn't plugged the sustain pedal.

The sustain thing happened to me.
It was almost like SST behavior.

Had to shut it off to make it stop.

Pretty sure it was pre OS 1.5

It hasn't happened again.

Had it on my Triton Extreme, was a broken solder contact on the sustain pedal input.

I've had this issue twice before, where a sound refused to cesase sustaining. Even changing programs didn't help, and a reboot was necessary.

This was back on 1.0.7 software though, it hasn't happened since.

Maybe you're right, but if it is a hardware problem, why is it going away after reboot?

And furthermore why isn't the problem permanent? It pops up ones in a while!
If it was a hardware issue, the sustain pedal whouldn't work at all.

If it's an intermittent short in the cable, then it will work exactly as you describe, popping up once in a while. Very slight changes in the relative positions of the pedal, cable, and keyboard may affect whether or not it happens. Last year, I had exactly this issue with a sustain pedal.

I have experienced this every so often, it's not a regular occurrence..
Now, three damper pedals later it still pops up when I least expect it.

This has happened on my Kronos once and 2-3 times on my Motif. i figured it had something to do with the key rather than the sustain pedal.
