Kronos 88 and RH3 keyboard faulty

Having now had chance to try this for a bit I can confirm that I'm also able to reproduce this behaviour - to a certain extent. I'm not getting anything like the rate of dropped notes shown in the video, however they are there occasionally.
Also this has only occurred when using SGX 1 - I've not been able to get it to happen using any other engine. Has anyone else found this? It sounds like it's just playing the attack portion of the sample and somehow dropping the rest, so maybe a disk streaming issue?

So both SV-1 and some Kronos have this issue? Wow!

i've tried it also. It couldn't be reproduced on my kronos 88 (serial 912). The only time a note was muted was when i didn't play properly (like pressing the key instead of playing it), that makes sense because the hammer action wasn't triggered at that time.

So, the horrible action shown on the video is something that i couldn't reproduce.

Could you tell me what version OS you have? Mine is 1.04.

Thanks

I couldn't duplicate the issue on my K88; SN 410; version 1.04. Good luck. I hope you get a quick and complete resolution. That would annoy the crap out of me.

i also have 1.0.4.

It was annoying when I thought it was my KX88-ruined piano technique. I knew the Kronos wasn't running out of voices, and the problem was too subtle to understand (at first).

My hope is that the worst-case scenario is a bad batch of RH3 keybeds/scanners made it into the Kronos production line, especially since it isn't a problem for everyone. [pure speculation - I hope it's a SW bug]

I'm contacting support again today with a link to my video.

your video explained it perfectly, there's definitly something wrong. I;ve tried lot's of things, the only way i could reproduce it was by pressing very subtle and soft on a key, like pressing with a velocity of 5 on a nonweighted keyboard. that way the sound was kind of cutoff which makes sense because the hamer action can't respond well that way. On my real yamaha piano it would behave the same way.

But your video is a totally different story, that is definitly not what you expect when you play the keys that way.

I'm struggling to see how it's a keybed issue when I can't duplicate it with any other engine than SGX-1. Are you getting the same issue using other engines?
1.0.4 here btw.

That's a good question - I've experienced it on the Rhodes patches. Are they from the SGX-1?

I'm afraid I haven't looked at the problem from the engine standpoint, but I noticed it one time on a percussive clav patch, but only once. The thing with E pianos and clavs are that they have all their inherent attack sounds/mutes going on, and I may have heard some of that and not the same issue.

I'll try this with a different engine when I get home. And my comment about keybeds is pure speculation. I HOPE it's a software bug.

+1 to that. If it were a keybed issue you would see it in other engines.

I spoke to Korg (UK) today and explained the situation, and checked that they'd heard the recording I uploaded on page 1 of this thread. They told me I need to send the 88 back to the dealer, and described it being "definitely not right", and as a "mechanical problem". So I'll be sending it back, and need to decide what to do next.

Just wanted to pick you guys' brains on this - as I'm no expert. My current thinking is very much that I'm not willing to take back that particular board even after repair - to my mind if a brand new £3000 board has one (or more?) intrinsic defects from the get-go I'm not likely to be in for a fun ride with it. However, I have to weigh this up against the potential wait for a new unit, and the chance of that one being problematic too. (Perhaps I could retain my dodgy one till a new unit becomes available, I don't know.) The third option of course is to cut my losses and just claim my refund, which would be a shame but I do need to have 100% confidence in something so expensive. I can't be doing with the potential hassle of waiting ages again for a brand new one and then have that not work too; I don't know the likelihood of that though. Thoughts?

Since only a few reported with this problem, your chances of getting a good one is pretty high. I guess it really depends on how much you like it.

You know what this sounds like to me? It's the sound you get when you tap a key quickly and then immediately afterwards lift the damper. If you lift too soon, you get a full sustain, if you lift too late you get no sustain, but if you lift just right, you get a shortened/muted sustain. It's a feature that emulates one of the key ways an acoustic piano behaves.

Does it ever happen with the damper pedal depressed?

Yes.
