dspMixFx Remote Bridge not compatible with macOS 15

Steinberg Hardware UR-C Series

I believe that Steinberg is false advertising the UR-C Audio Interface line of products by irresponsibly NOT supporting the current macOS 15 Sequoia for use with iOS versions of DspMixFx (an integral software part of the interface)

Clearly states that NEW FEATURES
*### Dedicated streaming mix *
dspMixFx now features a dedicated streaming mix with an exclusive effect slot. This slot features effects that can be assigned for streaming purposes only, such as gate, compressor, and ducker. The main output of the streaming mix also features its own multi-band compressor. This mix output is an additional output mix for UR22C, UR24C and UR44C. On the UR816C it can be selected instead of Mix 4.

ALL OF THE ABOVE FEATURES were introduced with UR-C version 3.0 that was introduced in 2024 yet the iOS dspMixFx Remote Bridge HAS NOT BEEN UPDATED since 2022 basically rendering it inoperable for macOS version 15.

Anyone that purchases this interface in 2025 and uses the latest macOS version WILL NOT be able to use the remote bridge which means that dspMixFx for iOS does not work.

Please Fix and/or advise the public in order to avoid user dissatisfaction.

Hello,

I am losing patience. I purchased a UR‑C series interface expecting full functionality of the dspMixFx UR‑C app on my iOS device while using macOS Sequoia (15.6.1).

The problem is not only with the dspMixFx Remote Bridge, which has not been updated since 2022, but also with the dspMixFx UR‑C app itself, which does not work properly. On my system, it is completely inoperable and cannot be used to control the DSP features, making the device unusable as intended.

Please update the Remote Bridge and the app, or at least clearly inform users of this limitation to avoid further frustration and misunderstanding.

Thank you for your prompt response.

Same MacOS, all working for me. dspMixFx UR-C and Remote Bridge.
