Kronos 88 and RH3 keyboard faulty

outjet · Post by **outjet** » Mon Oct 03, 2011 2:31 pm

Adding my new board to the mix. Just received my Kronos 88 from the dealer 3 days ago, and immediately noticed there was something amiss.

Here's a video with my key drops.

This is for a Kronos 88 - I've added my info to the 'fault analysis' thread also.

Same issue I'm having with my 73 along with several other ones. I'm returning the 73 tomorrow and putting together a post with all the details.
I'll also put the relevant info in the fault analysis thread later today.

Nice video BTW!

ok, today i've experienced this behaviour also on my 88 keys.

I was playing the piano in an Init combi (only piano's) on 1GH. Then it was easy to reproduce. Then i've tried the same on the Kronos German Grand Program, and it was much harder to reproduce only on the C1 and E1 note i could hear the note cutting effect. Not every time, but only when i used the Damper pedal.

Personally i don't think it's a problem of the RH3 keyboard. To me it sounds more like not playing the sample completely from the SSD. It sounds like it's start to trigger that sample and then suddenly stops (out of processing power or disk bandwidth overload?). I can not reproduce this on any of the other EXI models.

so:
It doesn't happen very often, but when i use the damper pedal and lots of notes then on certain notes i will hear this.

Well, you can add me to the list of people having this problem. I've waited since July for my 73 and now this. Very bummed and hope it's just a software glitch.

If it were hardware it would be seen across multiple engines. So things look good for it being software-related. Hope Korg gets on this ASAP.

This happens on several engines on my unit. The MIDI output shows the double-triggering where the second trigger is a super-low velocity value and that triggers the mute sample.

I can play Ivory II from my Kronos and get a similar effect. I can feel the hammer bounce in my fingers. Doubtful that a software fix should be applicable to my unit, but there may be others where it might be helpful.

I had not seen anyone post about it happening on other engines within the kronos. The fact that it happens through Ivory does not mean it can't still be software.
If it is hardware, that would be a big problem.

It can still be software, but Korg didn't jump to that conclusion and want to have my board back for an investigation. The general impression they gave me was that it was the hardware, based on their line of questioning, my video, the MIDI output and how my unit responded on all the other patches from other engines.

Very interesting. Certainly keep me/us up to date on any progress. Of all the issues people have had, I'd say this might be the most serious as it would very much impact performance/recordings.

I will absolutely update this thread as I get more info. Korg USA has been very responsive to my calls and emails - I mentioned this in a previous post.

I second this observation..

The MIDI output shows the double-triggering where the second trigger is a super-low velocity value and that triggers the mute sample.

I would bet on hardware from what little I have read. It's probably "fixable" with a software update. Hopefully Korg can address this.

Just because it doesn't happen with other engines could just mean that the engines handle these low value velocity notes in a different fashion.

I don't know if I would like a bandaid to address this hardware problem via software. Assuming you are implying the software look for this occurance and fix it. I'm just wondering what type of implications that would have? For example what if I did want to quickly play another soft note after the first note?
I'd be very curious how they implement that and worry about causing more issues than they solved!

Very interesting. I wanted to check out the MIDI output but thanks for actually doing it. That sounds right to me too -- from my experience you can almost feel the key bounce when things get screwed up. It seems to be more in how the note is physically played instead of what patch/engine you are on.

To support your theory, here's the MIDI output from the first blocked note mentioned in my earlier
post http://www.korgforums.com/forum/phpBB2/ ... 692#426692
and video http://4g.outjet.com/kronoskeyfail.html

(*Note - I hid the MIDI control output, which also showed the pedal depressing at the top of this measure)

The first two notes of the triad show being held for 000.214 and 000.205, vs the note that held for 000.043, followed up by the 000.187 quiet follow-up.

Yep - the same behavior I saw when I recorded the MIDI out into an external sequencer and looked at the data.

I haven't really dug into the onboard sequencer, but there it all is in your picture, clear as anything.

Obviously, you can easily miss this on a string pad, but I can hear the problem on harpsichord, organ and synth patches that have immediate attack w/no release.
