I have been experimenting with using the Kronos as a USB audio interface. I currently have a Windows 8 laptop with ASIO4All installed and use Cubase or Ableton live as a VST Host. This works great and VST instruments play back with acceptable latency.

However, when I try to use this in conjuction with Kronos internal instrument sounds (in combi or sequencer mode), the USB audio cuts out intermittently. The problem is more pronounced as I add more internal instruments. I have a feeling that the Kronos processor may be struggling to process USB audio and the internal instrument sounds at the same time.

It is not a problem with my computer (i7, 16GB RAM, SSD) because it never goes above 12% CPU loading at any time.

Does anyone have any ideas or solutions? I would really like for this setup to work because the main outputs of the Kronos are very high quality - noticeably better quality than most standalone audio interfaces.

Do I understand correctly that the issue only occurs when you use VST instruments in conjunction with Kronos internal instruments?

You meantion that playback of VST instruments works fine.
What happens if you use the Kronos internal instruments only?

Do you have a midi loop perhaps?

No problem using internal instruments. The issue only occurs when vst instruments are played at the same time.

Maybe JackAudio can help with any virtual connections needed to elimate any lag between both sources.

USB audio is handled by a separate sub-system (as is required when a system which would normally be a USB host functions as a USB device). It requires nothing whatsoever from the Kronos CPU. There is something else going on here, almost certainly on the Windows side of the equation; my guess would be your computer reacting to additional MIDI messages from the Kronos.
