Hello,
I have discovered another serious issue in Nuendo 14.0.32 (not tested in 14.0.40) when working with Metric Halo (MHLink audio driver) audio interfaces. All signals routed out of Nuendo and back in (e.g., for re-recording thru internal ASIO-MHlink engine) are being filtered with an approximate 10 kHz low-pass filter! When recording from line or microphone inputs of Metric Halo MHLink/MH console, not only is the signal filtered, but it also occasionally drops out in the recording! These issues do not occur in previous versions of Nuendo. Nuendo 13 works flawlessly with the same Metric Halo interfaces. It seems that, despite the improvements in Nuendo 14, these specific bugs make the N14 software currently unstable and unreliable for normal use. (: My DAW setup: Mac Studio M3 Ultra, macOS Sequoia 15.7.2; Metric Halo ULN-8 interfaces with latest software and drivers; Latest versions of Nuendo 13 and 14
Kind Regards,
Arturas Pugaciauskas Sound producer
P.S. Since these issues appear only with Nuendo 14, I suspect they originate from Steinberg’s side. But I will also forward this information to Metric Halo support.
I have three different interfaces and have experienced no issues rerouting the summed stream back into Nuendo 14.0.32, though we did occasionally experience dropouts in recordings on N12, but not since.
My initial assessment was that this was likely due to older ASIO handling or buffer management, which Steinberg significantly improved in later versions.
The fact that you are not facing any summing glitches suggests your clocking and routing are solid—probably all devices are sharing a reliable master clock or are aggregated cleanly.
However, a consistent ~10 kHz low-pass filtering on return-routed signals (through the internal ASIO-MHLink path), along with intermittent dropouts on direct line or mic captures, strongly suggests that Nuendo 14’s new audio engine or buffer management layer is mishandling either the driver’s sample-rate negotiation or buffer alignment during internal bus loops, or a double conversion (float ↔ integer) through CoreAudio or ASIO Bridge layers—especially when routing back into record-enabled tracks.
Since Nuendo 13 performs flawlessly with the same Metric Halo setup, it’s almost certainly not a hardware or MH Console issue, but rather a change introduced in Nuendo 14’s audio-path optimization. (Steinberg adjusted internal resampling and precision handling for hybrid routing.)
You can try sending a full-bandwidth tone sweep (20 Hz–20 kHz) out via MHLink and re-recording it internally. Then compare the spectrum with the same test in Nuendo 13—you should see a roll-off starting around 9–10 kHz only in 14.0.32.
Steinberg quietly patched several routing and summing issues in the 14.0.40 maintenance update; you should run the same test with that version.
Finally, share screenshots and test results with both support teams.

Hi,
Thank you for your insights. I’m not trying to experiment with version N14.0.40, because after I installed it and find that the Dolby Atmos engine (which I really need) was seriously broken, I went back to version 14.0.32, and after this ASIO–MHlink issue, even to N13. I really hope Steinberg will soon fix this crazy mess caused by version N14 because as a customer I actually have the right to ask for a refund for the upgrade to N14, since I’m forced to work with N13
