Pleased you've found a workaround and can record stuff...
Before getting into suggestions ,I must mention that I don't have real evidence as to what the real cause of this problem is,nor do I offer any guarantee of a "cure".
Willing to share my own experience and opinions etc…..hope they may help.
My suspicion lays around the iMac….usb ports….and the audio settings with the iMac being very fickle at times.
The Kronos itself is not the real culprit per say,but it does need certain consideration as to settings.
Two main ones being the usb input needs to off……otherwise,audio from the iMac will merge with the main outputs,then onto the usb, which in turn will present a loop.
(The usb input can routed elsewhere,but that's another consideration).
The other is to adjust the master slider audio accordingly…..some progs/combies can go too high.
As a quick check,I use Audacity audio recorder,for simplicity reasons,setting up is minimal and is a free app.(downloaded from the web).
It has been known that using an usb2 hub helps….but currently, I can successfully use the usb3 ports,(or an usb3 hub),so it's not conclusive.
Also,some users find it better with the Korg usb midi driver removed.(Note…the Editor will need this installed,though).
The iMac settings are in two places…. System Preferences/Sound and Audio midi Set Up applets…..both are interactive,but will need checking separately.
May be worth setting up an aggregate device (Audio midi Set Up)….the most important parts being to set the Kronos as "re sample this device" and the imac sample rate to be 48kHz.
Also, mute the microphone on the iMac.
If you require further detailed info of my own settings,let me know and I shall provide them…however,due to its long winded writing,perhaps better to send it via pm.
May prove to be boring reading for other members if posted here….??
Have tried using El Cap again,but became a "hit & miss" affair and gave up.
My current osx is Mountain Lion and things work fine…..following the initial set up etc.(Perhaps worth considering using that…??).
Using Audacity for quick checks,then my usual daw…Cubase Elements.
My recorded audio is routed out of the iMac(as per aggregate set up) into a small mixer,as does the Kronos main outs…plus other instruments, then onto the monitors.
Hope this has helped to some dergree.
Do let me know if you need further info…..shall provide answers to the best of my ability etc….
Good Luck.
Best Wishes.
