Fixed: DSP2 is occupied by resource after changing the Digital Mode |
How to reproduce the problem 1. Insert EQ 601 and Compressor 276 on DSP2 as much as the resource reaches the limit (100%). 2. Switching Digital Mode from ADAT to S/PDIF or vice versa. 3. DSP is occupied by the resource. DSP resource should be released after the Digital Mode has changed. |
Fixed. Please update to TOOLS 2.0 if this problem is occurring on your system. |
| In case that recalling the scene containing a different digital IO mode and channel link (Stereo and Mono), channel link setting in the scene data of dspMixFx AXR is not properly recalled when using AXR4 with Cubase. | How to reproduce the problem 1. Enable a Channel Link option in the dspMixFx AXR setting. 2. First, make a Scene 1 file (All channels are stereo-linked, digital IO sets to AES/EBU mode.) and next, make a Scene 2 file (All channels are mono, digital IO sets to ADAT mode.), and load a Scene 1 file again. 3. Make stereo buses for all AXR channels in the Audio Connections menu in Cubase 4. Load a Scene 2 file to dspMixFx AXR. Mono channels in the Scene 2 file are linked in stereo dspMixFx AXR. |
Workaround: Disable Channel Link option in the dspMixFx AXR |
| Noise | DELL ALIENWARE 15 R4 After a certain time, the audio signal gets unstable and the AXR4T starts to generate noise. The problem is related to a delay between the AXR4T and the computer caused by system-specific DMA data transfer issues. |
A solution or a workaround has not been found so far. |
| DELL Precision 7530 The AXR4T is generating noise even though ASIO buffer size is set to maximum. This system-specific issue is being caused by an unusually high DPC latency. |
A solution or a workaround has not been found so far. | |

Please do one of the following. Workaround: |
| After installing the Yamaha Steinberg Thunderbolt Driver, drivers for other devices installed earlier may not work (or vice versa). |
How to reproduce the problem The driver installed in Step 1 will no longer work and the device will be unusable. If the steps are performed in reverse order, AXR4T will become unusable. This only occurs on Intel-based Macs with macOS 11 installed. |
Workaround: Please update to macOS 12. |
| A warning message appears when an AXR4T connected in a stack is turned on. | How to reproduce the problem 1. Connect the first AXR4T to the Mac and turn it on. 2. Connect a second AXR4T without turning on the device. 3. Start Cubase. 4. Select "Yamaha Steinberg Thunderbolt" in Cubase. 5. Turn on the second AXR4T. The "Audio Hardware Removed" dialog appears momentarily. |
A warning will be displayed, but the AXR4T can be used. Workaround: When stacking, all AXR4Ts must be connected and powered on before starting Cubase. |
| Using FIRMWARE UPDATER with stacked AXR4Ts (Firmware v1.20) may cause the Mac to reboot. | How to reproduce the problem 1. Power off the first AXR4T in the stack and power on the second and third units. 2. Start dspMixFx AXR. 3. Turn on the first AXR4T. 4. FIRMWARE UPDATER starts automatically. 5. Cancel the FIRMWARE UPDATER. 6. Turn off the first AXR4T. 7. The message "AXR is not detected. OK" displayed. 8. Turn on the first AXR4T with the message displayed. The Mac may restart while three AXR4Ts appear in sequence in the FIRMWARE UPDATER. |
Workaround: - When updating the firmware, please do so with only one AXR4T connected. - Do not turn the power of AXR4T on and off while dspMixFx AXR is running. |
| The name of the digital port in the audio application is not properly changed when the digital I/O mode is changed. | How to reproduce the problem 1. Start Cubase. 2. Start dspMixFx AXR and change the digital I/O mode. The name of the digital port in the audio application is not properly changed when the digital I/O mode is changed. This happens only when the digital I/O mode is changed, but the channel count of the digital port is not changed. (Ex. changing ADAT to AES when Fs=48kHz) |
Workaround: |
| Yamaha Steinberg Thunderbolt (High Precision) driver cannot function properly on macOS 11. (32-bit integer playback/recording is not available) | How to reproduce the problem 1. Start Cubase, select the Yamaha Steinberg Thunderbolt (High Precision) driver, and create a project with the desired sampling frequency. 2. Make a recording and play it back. Silence is recorded, and playback sound is also silent. |
Workaround: Please update to macOS 12. If playback/recording in 32-bit integer is not required, select the Yamaha Steinberg Thunderbolt driver or the Steinberg AXR4 2TR driver. |
| Sample rate mismatch between Cubase and AXR4T | How to reproduce the problem 1. Save the project that Cubase runs with an audio interface except AXR4. 2. Before AXR4T connected to Mac, Set a sample rate other than a clock that Cubase project currently uses. 3. Connect AXR4T to Mac and switch an audio driver to Yamaha Steinberg Thunderbolt driver in Cubase. |
Workaround: |
| In case that recalling the scene containing a different digital IO mode and channel link (Stereo and Mono), channel link setting in the scene data of dspMixFx AXR is not properly recalled when using AXR4 with Cubase. | How to reproduce the problem 1. Enable a Channel Link option in the dspMixFx AXR setting. 2. First, make a Scene 1 file (All channels are stereo-linked, digital IO sets to AES/EBU mode.) and next, make a Scene 2 file (All channels are mono, digital IO sets to ADAT mode.), and load a Scene 1 file again. 3. Make stereo buses for all AXR channels in the Audio Connections menu in Cubase 4. Load a Scene 2 file to dspMixFx AXR. Mono channels in the Scene 2 file are linked in stereo dspMixFx AXR. |
Workaround: Disable Channel Link option in the dspMixFx AXR |
