I have no idea why I don't get the SPDIF out of my Kronos working with my Scarlett 18i6 audio interface optical in.

The Kronos digital out is connected via Toslink optical cable to the optical input of the Scarlett. The Kronos sync is set to internal clock. The Scarlett Mix control is set to 48 Khz and SPDIF connection, but still fails to sync and receive audio from the Kronos.

I simply run out of ideas what might be the problem. I emailed Focusrite with the same question. Anybody got a possible clue?

AFAIK the Scarlett uses RCA SPDIF and optical for ADAT (on the 18i60 model).

ADAT is always optical. SPDIF can be either RCA or Optical. the two optical formats are not inter-compatible though.

Thanks, XTrade!

I thought both digital ins had SPDIF, but in fact the optical in has ADAT format. Looks like I need a digital converter, or wait for the Kronos plugin end of November to use USB.

I know it means adding another box, but there's plenty of SPDIF to RCA/RCA to SPDIF converters out there. I'm using an M-Audio CO2 converter (admittedly with my Fantom, but also works fine with the Kronos). Amazon sells similar converters, but much cheaper if money's tight.

I have a couple of those cheap unbranded optical to coax SPDIF converters Kronik mentioned and they are indeed cheap to buy ($20 kind of price) and on the few occasions I've needed to use them they've worked just fine. I keep a couple in the studio cupboard "just in case".

Thanks for the hint, Dan, and to you others.

As far as I see, I only get a directX connection with the present Kronos USB driver in Win7. Or do I overlook something?

I ran into another problem I should mention, because you could/should perhaps pass it to the development team:

- I had installed the Kronos USB driver and was using the USB connection just for midi (Kronos to Win7/64 notebook).
- Then I installed an update for my DAW, Sonar X1 Producer.
- Recording audio suddenly introduced crackles I hadn't had before. I thought it was the Sonar update and went nuts bug hunting, driver, latency and buffer size checking, uninstalling and reinstalling
- after all efforts failed I tried to remember all changes after my system still worked (not too many on a dedicated music notebook) and the Korg USB driver install came to mind
- I unplugged the Kronos USB connection and everything went back to normal. I'm using the Edirol UM-1 (basic midi to USB) cable now to connect Kronos midi via the normal midi in/outs. But I hope that the driver will be updated to Asio and/or WDM and will work ok with the coming plugin software.

In one word: the present USB midi driver seemed to introduce audio crackles into my DAWs audio recording. I have no idea about the kind of interaction which caused this, but my suspicion is, that besides the midi driver, the audio stream might have been active in some weird way.

For the moment, a cheap ADAT/SPDIF converter will do. I already ordered one.

No Asio driver???

That sounds really strange. I know Asio4all, but it only does a good guess on timing and is no full replacement for Asio drivers. It is mainly used for cheap onboard cards.

DirectX is no satisfying alternative as well. If no Asio drivers are provided - which would kick the Kronos connection out of what is considered the professional standard for all serious Windows systems sound cards - WDM drivers would be the very least which is needed.

I don't want to grumble, but I'm seriously concerned now.
Are you absolutely sure?

I too find this more than a little shocking.
ASIO is essential for professional recording in a Windows environment.

There is this awful tendancy for a few companies to drop developing their own driver, pointing users towards ASIO4ALL instead for their USB-Audio products. Behringer is a good example.

ASIO is not a suitable alternative for a professional recording environment.

I guess you could argue that a professional recording environment may have the facilities to connect SPDIF or may just prefer to use analog anyway... But that is just defering the work to another manufacturer's product - imagine if all the companies did this!

Re Sonar:

Sonar X1 - Edit - Preference - Playback & Recording :
Driver Mode: The default is WDM/KS. Korg recommends that you select MME instead.
