Damper pedal problem/query
Moderators: Sharp, X-Trade, Pepperpotty, karmathanever
If you have a reverse polarity damper pedal and set the Global mode accordingly, when you pull the damper plug, the notes will sustain indefinitely. That's the way it works if you think about it. I have a Kawai F20 dual pedal which has reverse polarity so I'm aware of this. Another problem is that in reverse polarity, the damper input does not work the same as normal polarity. If you want half damping to work you need a pedal with approximately 1000 ohms resistance. To the best of my knowledge nobody makes such a device. I had to put a 1000 ohm resistance in parallel (I made a little box for this which also acts as a cable splitter for the Kawai). Half damping now works like a charm except for EP-1. There's a bug in that half damping occurs in the wrong place. They are aware of this but have done nothing about it. I live in hopes!

>So I take it you didn't try the test I offered?
What would your test prove? This is an intermittent problem that occurred over 3 different pedals. Your test is not any more conclusive than the multimeter test I did. I understand what your test does.
I understand what you are trying to say about this. I really do.
What you are missing is that what I am asking for is a way to shut the notes off without having to restart the machine. Once this happens there is no fix AFAIK.
I know you think that I don't know anything about how a circuit works etc... that is fine. Please visit diystompboxes.com/forum if you care to.
Wait!!!!! Your idea is great for this.... I will carry around a 1/4" plug and simply short the ground and tip on the gig and open the circuit back and forth. That will end all questions when this happens!!!!
I take back everything I said!

Bryan,
Yes, that may be the easiest fix. I am trying to track down a pedal - no one has a Korg pedal here. Will see if I can find another type. Have to play a concert tomorrow. If it comes down to it, will use my PC3 instead.

CPilot, yes, but even when set to reverse polarity - when the unit turns on, it does not sustain. Therefore there is init code that can manage this part of the sound engine. I was hoping there was a way to reinit the engine so when I pull the pedal, it can act like it just started up.
Just called all around. No Korg type pedal here. Oh well. Time to program the PC3 a bit more.
Thanks,
Aron

sorry if you were offended by my comments. Until I saw the link for your website which I went to, I wasn't sure of your knowledge of basic electronics. Obviously you know what time it is. So that at this point I would say maybe you should have your Kronos in the shop. Obviously there is some defect with it. As far as a panic button mode, Dan At Korg is probably the best source of information being as he wrote the manuals for the Kronos. If anyone would know it would be him.aron wrote:>So I take it you didn't try the test I offered?

I actually do think your idea is great. It will prove once and for all if it's the pedal (which as I said it could be). I am tracking down a Korg pedal now.
I am still bothered by the fact that this could happen to anyone that uses a Yamaha type pedal which they probably shouldn't considering what can happen.
I have no problem with purchasing a Korg pedal if it will fix things. Tracking one down is interesting. Probably will order away. It's not a problem for Thursday. Just had to reprogram a few sounds in the PC3. It's good to go.
Thanks!
p.s. I'm going to carry around a 1/4" shorted plug. If this ever happens I will be able to test this problem immediately.

To shut down hung notes, try switching modes to Program or Sampling or Global ... whatever. That should turn off all sustained notes. I believe the COMPARE button should also do the same thing. You can test these by holding down a chord and seeing if the notes do turn off.[...]I am asking for is a way to shut the notes off without having to restart the machine. Once this happens there is no fix AFAIK.
Yes, sorry I am not making myself clear (not the first time!).
Is there a way to shut off the notes and be able to continue using the keyboard.
Yes, there are ways to shut off the sound (thanks for the compare) but you cannot use the keyboard after that. The notes just sustain and are stuck.
I've been trying to shut off the sound. I'm not sure if there's a way without turning the unit off.

OK you guys. I hope you never have to go through what I went through on 2 gigs. Here is a band aid fix.
Load the following .mid into your Kronos. It will generate all notes off and give you a fighting chance to continue playing. Right now it takes 4 secs to shut off the notes, but it's better than 2 1/2 minutes!!!!!
http://www.aronnelson.com/kronos/alloff.mid
I loaded the MIDI file, upped the tempo (set the tempo to manual), then saved the song. (This decreased the time to a couple of seconds now) At least I don't ever have to turn the machine off now if I ever have a bad pedal or ????
So if you have this extremely unfortunate event happen to you. Pull the pedal, play the sequence and keep playing.
(I guess that's why some keyboards have panic features - very useful for real world problems)
Hey, thanks for all of the help and suggestions. Will get a Korg pedal and hopefully this won't happen again. As I have a way to get out of the problem without having to restart - I consider this matter closed. Thanks!

Thanks Bryan. Yep, anything is possible.
Hey BTW check out LPS 1 - the spray can. A long time ago I did a bunch of tests with deoxit, cramolin etc... on 2 Sequential Pro Ones that I have.
Deoxit/cramolin lasted about 3 months. LPS 1 kept going for about a year or more. Since then I have been using this on pots, jacks, j-wires. It works really well and I have never had any problems using it.
