Cubase 13 problems when working whith 2 audio interfaces

I’m experiencing issues in Cubase when switching between two audio interfaces: the iRig for vocals and the Mooer GE300 for guitar. Both are used within the same project. The problems include:

  • Device Recognition: Switching between devices sometimes requires a full system restart or driver reinstallation for Cubase to recognize them. Occasionally, the switch is seamless, but it’s inconsistent.
  • Sample Rate Conflicts: After reinstalling the iRig drivers, it’s only selectable at a 48,000 Hz sample rate, causing pitch alterations in existing projects.
  • System Crashes: Cubase has crashed during sessions, and attempts to open the latest backups result in licensing errors. These errors disappear after a system restart, but the backups remain inaccessible.
  • Device Disconnection Post-Hibernation: After resuming from hibernation, even if the devices are powered on beforehand, Cubase fails to recognize them, necessitating a system restart.

I’m seeking advice on efficiently managing multiple audio interfaces in Cubase without frequent restarts or driver reinstallations. Any insights or solutions would be greatly appreciated.

Cubase works best with a dedicatied ASIO driver but you can’t use more than one ASIO driver at a time.

You could try something like FlexASIO if you want to combine different interfaces but that will usually mean some form of software sample rate conversion taking place – that’s the trade-off for the convenience.

Regarding hibernation, on a DAW computer you should disable hibernation permanently.

When I start my guitar processor, Windows always recognizes it, and I can hear sounds from web browsers and other software. However, when using the Generic Low Latency ASIO driver in Cubase, the processor is not visible, and Cubase doesn’t detect it, it is not in the list:

I have to restart my PC for Cubase to recognize it.
Is there a way to avoid having to restart my PC every time I need to switch to the guitar processor in Cubase?

thanks for the FlexASIO link !

You need to choose the FlexASIO driver in Cubase.

I’ve noticed sample rate issues when switching audio interfaces on and off in Cubase. Both my devices support the same sample rate (48 kHz) and are connected via USB. Does this mean FlexASIO won’t perform any sample rate conversion, given that the signal is already in the correct sample rate and is digital?

Additionally, do I need to keep the iRig drivers installed for FlexASIO to function? And how might using FlexASIO impact latency, especially when playing a MIDI keyboard?

Hi, though I haven’t tried it for myself, my friend told me he successfully combined Focusrite and Behringer audio interfaces simultaneously using asio4all. He activated both on asio4all’s control panel and used all available audio inputs for recording. Maybe it is worth giving it a try

If you read the FlexASIO FAQ , it seems to suggest that no unnecessary sample rate conversion takes place in cases such as yours where both interfaces run at 48kHz, however I don’t think that could be guaranteed.

You may need to play around with the configuration file and check the log to find out what’s really happening in your specific case.

You’re right—it’s all about selecting the correct driver. As seen on my screen, I was using the Generic Low Latency ASIO Driver, which doesn’t pick up devices that are recently turned on.

I’ve tried Cubase’s dedicated ASIO driver, which works better because it adds newly connected devices to the list without restart of PC. However, the issue remains that I need to manually reconnect audio inputs and outputs in the Studio/Audio Connections every time I switch between audio interfaces.

I wonder if there’s a way for Cubase to memorize these audio connections and automatically reassign them when switching interfaces.

Next, I’ll test the FlexASIO driver to see if it offers a better solution.
