Kronos Latency?

I tried to follow Jordan Rudess playing, but I couldn't keep up.
Glad to know I can now blame the Kronos latency.

No perceived latency here either - I often do feel it with many soft synths though so it's not like I'm immune to it.

I sometimes think I can feel a slight latency in CX3, when playing a succession of many notes, for example in a smear.

It's weird. I've not felt it on anything else before. Naturally the audio latency should be constant so I can only assume it would be some kind of control message saturation.

Have you latent guys tried triggering the Kronos from an external keyboard that produces its own sound source? I ask because I have been running (and collecting) Macs since the G3 days....

....in any case one of my semi-retired Mac Pros is a dual 2.3Ghz G5 that is controlled by an old Roland HP series SAS piano. When the sound is turned down on the Roland piano and I trigger Pianoteq4 from it, I feel almost zero latency, but when I turn the volume up on the Roland's internal speakers I can definitely hear the delay between the time that it sounds, and then Pianoteq sounds.

This is not an issue on any of my Intel Macs, not even my first 1.8 Ghz. The 2.4 Ghz iMac and MBP Core duos are tight as a frog's behind. I neither feel nor hear any latency whatsoever.

Try it if you haven't and see what your ears think about the latency some of you think that you feel.

Just for information I am a drummer and I can feel latency from my Edrum when there is one (i.e when connected through midi to a VSTi with more than 8ms).
So for me the Kronos has less latency than that value !

Cheers.

I must say I most definitely DO experience latency on an 'original' Kronos 88 note. But when I tried a Kronos X 88 note in a shop it it did NOT seem to suffer from any noticeable latency... (though evaluating latency in a shop is not easy!)

I vote "imagined difference" unless there is something wrong with your Kronos or your monitoring situation. Also consider that with these millisecond values we're talking, listening distance actually matters. E.g. sitting one meter (like 3ft4 I guess) away from your monitors adds roughly 3ms of latency.

I use an 88 at work and have two 73s. No latency noticed.

BTW, when touring with a choir in college, we performed at an historic church in Philly. The organ had a half second delay. The director and accompanist never told us before the concert. The accompanist played so skillfully, we never knew! Amazing chops!

No it is not imagined unfortunately. I am cursed by being unduly sensitive to latency. I cannot cope with playing through monitors that are 8 foot away from my ears for that very reason. I FEEL it more than hear it, actually...

I read that the original Kronos measures at about 10ms latency. I wonder what the X measures... anyone know?

And as for half a second.... !!!

Pretty sure that even if there is a measurable difference it's negligible, considering they use essentially the same hardware and software. The CPU soeed difference is so small there really is no way for a significant latency drop.

Yes the difference is processor speed is negligible. 1.66ghz vs 1.8ghz if memory serves me correctly. But IF Korg had adjusted any buffer on the X, that COULD make a difference.

I just tried playing the Kronos from a Motif Xf via midi and the Kronos feels very slow under the fingers versus the Motif played locally (not that the Motif is fast under the fingers either!)

You may have read it, but it is not true. See my earlier post.

There is no difference in note-on times between the different models of Kronos.

Quite doubtful, in my opinion, that the Kronos is "very slow" in comparison to...well, anything, actually. Low and consistent latency was one of the primary goals during the early development stages for the OASYS, the predecessor to the Kronos. As noted in my earlier message, the Kronos latency is lower than that of some very, very popular synths.

According to this article in Sound On Sound, the Motif Rack, at least, is far, far worse - and also extremely jittery:

Dan thanks for letting me know that the X is the same as the original Kronos in terms of latency. Unfortunately that is not what I was hoping to hear!

btw. I would not say the Motif is any faster 'locally' (ie. not played over midi) than the Kronos 'locally' - they feel about the same to these fingers in that regard.

Also, just to put things in context, I'm bothered by latency to some extent by most keyboards that are out there! Older boards often fare much better in my perception, strangely enough... Wish I could rewire myself not to feel these miniscule delays!

Thanks for the replies.

So again, "imagined difference", unless there is something weird about your monitoring situation.

So, are you saying that you think there is a difference when playing via MIDI?

When doing so, is there a direct connection via a single cable from the MIDI output of the controller to the MIDI input of the Kronos? Or, is there a MIDI interface involved?

Indeed - especially since some older keyboards were much, much worse.
