Hello, are there maybe other S1 version 2 users with this problem? When I connect the Kronos 88 platinum to the Macbook Pro, after short time the audio gets distorted. The Macbook is recently updated to SSD with 16 GB RAM because I needed this to do for Keyscape. When the Macbook is connected to the audio interface of the MOXF there is no problem of distortion, also not when it is connected to a Tyros. With the MOXF and Tyros I pushed the Macbook's CPU to the limit with heavy Keyscape/Omnisphere patches but no distortion problem. On internet I found out that I'm not the only one with this (probably) Kronos problem but I didn't find a clear solution. Are there Kronos users in this forum who have this problem also and know if there is a solution? Or a hint?
Addition. When de Kronos in connected to S1 and I am not playing instruments or recording, so when I do nothing, after some time this message appears in S1: "The audio engine has been stopped, because the system became unresponsive due to an overload in the audio engine." So it looks like there is activity between the Kronos and Macbook/S1 even when I don't do something. Thanks, Jaap.

Are you running more than one audio interface at the same time so that the kronos becomes an aggregated device?

Thanks. No, just the Kronos alone.

Could be a The Kronos driver issue.

Can you connect the Kronos to Studio One via Midi IN/OUT instead. Do you have any midi interfaces you could try this with. Or any audio interfaces with Midi IN/OUT on it as well. Could be a USB issue. I have got a friend who runs this setup and I will check with him. He also uses a MacBook too. I will get back to you. He is a musician and has not woken up yet!

Hey Japiedepapie
Since I don't have a Kronos to test with not Macbook.. I can only hasard a guess Could it perhaps be something like in windows where it turn of curtain components for power saving or the sorts? I'm led that way since you mention that it happens when you are not doing anything for a while (Playback/recording) Ch33rs Saga

My friend finally woke up! Anyway he does not use it on USB only over midi occasionally and it is all fine.
I see the latest USB driver is 2 Feb 2017. (Win 10) What OS are you on? Have you got that one loaded up? My friend did say get the latest firmware as well. That is like 24 Feb this year! Just released. It is important to keep your synth firmware totally up to date with the latest drivers. Final Saga also has a point. Go through and switch off all the USB power saving options. Dumb concept for us music producers who need everything working all the time.

He is on osx, probably one of the latest. Using midi only will do no good since the kronos becomes a soundcard and that is coreaudio/coremidi compliant that needs no driver.
I would try and disable the osx system sounds so that they don't get routed to the kronos, as I suspect they do right now. Depending on your setup you may end up with two different sample rates; One for osx and another one for the daw. Normally osx applies SRC to make things work but it may lose sync over time for some odd condition. My kronos is in the studio so I can't check if sample rate must be set on its console or if the control panel can change it.

Well being on a Mac changes things slightly. The firmware download (3.1.2) is still for PC/MAC though and there is a USB driver for MAC (1.2.3 r9) but it is dated Dec 2016. If that is any help. Does that replace the standard coreaudio/coremidi non driver mode. Not sure as I don't own one.

Hi guys, thanks for the input! Followed the advices but no result. I'd like to tell some new things.
1. Kronos midi In/Out to usb Macbook gives no problem. The audio comes out then via the headphone output of the Macbook and not via the Kronos. No distortion. 2. Background activities are minimal, no wifi, no App Nap, no mail, Safari etc., only Studio One. 3. Latest firmware is on the Kronos. 4. Removed the Korg driver, still distortion. Jemusic, you write about switching off all usb power savings. Could you tell how to do that? Bye, Jaap. |

I thought you were on a Windows machine and this can be set but for Mac not sure. I have done some research and from what I have found some Macs put the USB ports to sleep only when the whole computer is asleep. Which I am suspecting yours would not be sleeping. I have also read that even though the computer may be asleep some USB ports on some models are not. What that means in your case is I don't think there is a USB power thing going on creating the distortion.

Hi Jemusic, thanks. Today I added the Mac specs, should have done this right away.. There is much to read but not a clear solution. And also it is not clear where the problem is, in the Kronos (maybe the driver) or the Macbook. Anyway for now I'm happy that Kronos midi In/Out to Macbook usb works ok, that means that I can use the Kronos as a controller for Omnisphere/Keyscape. Today I wrote to my dealer for advice (a terrific dealer) and also to Korg. If there comes a solution I'll write it here.
Bye, Jaap. |
