Hi all.  I'm looking for urgent assistance with a likely sample rate mismatch issue between my RME HDSPe card and VSL's Synchron player (I'm on W10 v1903 using the v4.29 driver with a Multiface II) 

Short version:
I think there's an issue with the Synchron player upsampling from their native 44.1kHz to a higher sample rate that is unique to the RME card.  Using sample rates of 48kHz and up results in a horrible digital buzzing sound analgous to a very low bit rate sound. It becomes worse the higher the sample rate. Can anyone confirm?

Longer version:
Full details at https://www.vsl.co.at/community/posts/t … post298898, but I recently purchased Synchron Percussion I Drums and the Bass drum has a strange ringing that I can only describe as similar to that high pitched 'digital' sound you get when you lower the bit rate. I thought it was restricted to the Bass drum but it is actually audible in ALL of my Synchron library instruments, it's just more noticeable with low frequencies (with high frequency sounds the ringing sound is masked).

There is a WAV file attached at the above link to illustrate

I then discovered that it looks like it's due to a sample rate issue with the Synchron player working at 48kHz, because working in Cubase at 44.1kHz fixes the problem. However, because I have to work and deliver at 48kHz for film this isn't a solution for me. Increasing the sample rate to 88.2kHz or 96kHz makes the high digital buzzing sound so bad that the original sample being played is unrecognisable.

Same thing happens in the stand-alone Synchron player. If I go into the sample player preferences and set the sample rate to 48kHz or higher (and my RME interface Hammerfall DSP Settings changes the sample rate to reflect the selected sample rate as you'd expect) the digital buzzing sound is present. Switching back to 44.1kHz in the stand-alone application (with my RME interface Settings switching back mirroring the player as normal) and the ringing is gone

I don't have this behaviour in the Vienna Instruments plugin or Kontakt so this is clearly a Synchron player issue. However, I can't find any other users reporting this so I now suspect it is unique to HDSPe users.  Can anyone confirm?

Starting to get desperate now because I bought a few Synchron libraries I need to integrate into my template prior to a job starting shortly (my first job in almost 9 months thanks to effing COVID19 - about time!)

I hope someone can assist!

Thanks - Brett
