RME DIGI9636: Very Tinny

[jw1]

Hi, I have an OASYS keyboard, SPDIF Out into my RME DIGI9636. Everything is sampling at 48khz. I'm using Vegas software to record. The sound quality is pretty bad ... there is a tinny ring on every note. I hadn't noticed it on the first project I did with this set up, but I was using a lot of combination patches on the OASYS and they may have masked it. Now, though, doing straight piano (or any other straight patches) I can hear it quite clearly.

At first I thought I'd blown a cone in my monitor speakers ... sounded a bit like that ... but it is tinny right at the computer input.

The sound presented at the OASYS headphone jack is exceptionally clean.

Any thoughts on where I should start looking to try to debug this?

Thank you very much,
jw

if you click your little hammer on the lower right bar thingy in windows, who is master?

Also check to see if it says "sync" and not "lock" on the spdif in

What you are describing sounds an awful lot like the RME SPdif trying to resync to your keyboard

Try the keyboard as master and the RME as Autosync

Also, temporarily, make sure vegas is is MME mode, not asio, till you get the clock 100% sure

My first guess based on what you describe is that there is a feedback loop occurring.

In any case, I would checkcarefully the signal path to see whether you are getting a mixture of recording/playback signals occurring.

I think it's a sync problem as well. Try some different master/slave settings.

Hi again, and thank you all for your posts. I did try playing with the sync, but to no avail ... but, sorry, I could not figure out how to keep vegas in mme mode.

In case this might help,
Here are my RME Settings:
MME: Check Input: checked
Monitoring: checked
AEB: ADAT 1 Int.: checked
Buffer Size (latency): 512 (12ms)
SPDIF In: ADAT1
SPDIF Out (nothing checked)
Clock Mode: AutoSync
Pref. Sync Ref: SPDIF In
Sync Check:
Adat 1 In: No Lock
Adat 2 In: No Lock
SPDIF In: 48 kHz
Sync Ref:
Inp. SPDIF In
Freq. 48 kHz
Time Code: -:-:-

And my OASYS Sys preferences:
System Clock: Internal (chosing Word Clock or S/P DIF gives me "CLOCK ERROR").
S/P DIF Sample Rate: 48kHz

Thank you for any additional consideration you might be able to provide.
sincerely,
jw

Any good reason you got the AEB checkbox enabled?

In Sync Check, SOMETHING better say sync

There really wasn't a good reason ... ignorance on my part! Very strange, I cannot get anything under SyncCheck to read "sync" but (many thanks to you and the other posters here that drove me to look much more closely at the connections) I did find my trouble with this tinniness. This is my first experience with connecting up digitally, and I hadn't checked the box I'm monitoring from on the RME ADAT1 Output. It's input was set to Master. Setting it to Slave got rid of the tinniness.

Now, of course, I am curious what I'm missing without having SyncCheck read "sync" on anything ... I can record, seemingly find, into Vegas from this. But, this is probably more RTFM'ing on my part.

Again, thank you so much everyone!

Much appreciation,
