Let the user choose the outputs pair of its ASIO device

• Mar 27, 2020 - 09:55


For the momoent, it seems impossible to use an ASIO device that have several audio outputs pairs. I have a Allen & Heath ZEDi 10FX, which has 4 outs. I would like MuseScore to let the audio pass through the outputs 3&4 and not 1&2, but I can't find this choice under preferences. So I guess it's not allowed for the moment. But I think it would be a good idea to implement this idea, because a lot of professional audio interfaces have more than 2 outputs.

Thanks for reading,



this is something that I would expect the driver for the device in question to have options for, does it not? If not, that seems like something worth reporting to them, But meanwhile, I would also expect any DAW software to be able to do this, so if you route MuseScore's output to your DAW, you should be able to re-route it from there.

Hello Marc,

Based on all my other audio softwares (notation, DAW, synths, etc.), this is something I would expect directly from MuseScore itself. Indeed, in Reaper, Ableton Live, Guitar Pro, Traktor, Massive, FM8, Usine or Guitar Rig (to name a few), we are able to choose which hardware outputs are associated with software outputs. This is why I posted this feature request. The software utility of the audio interface is rather the place where we set the volume of each input/output, the activation of one or all of them, etc. Some audio interfaces allow some routing options (sometimes a lot, like RME and UAD interfaces) directly set by the software utility but not the function I asked for.

Thanks for your suggestion, I can route the audio of MuseScore via Reaper (for example) but the idea was to only use MuseScore, not a workaround.

I understand that it may not be a priority for the dev department. It would just be more handy :)

Have a nice week,

Take care.

Understood, but I have absolutely no idea if lo level info like that is actually available to MuseScore, which really doesn't deal with hardware directly but rather relies on higher-level libraries to allow cross-platform support (Windows, macOS, and Linux). Makes sense that DAW software would work with the hardware more directly, of course.

Okay Marc, thanks for your reply. It should be possible since several cross-platforms applications (Reaper for example) have the possibility to choose the ASIO outputs. But as you implied, it may be quite complex. I will use APIs other than ASIO in the meantime.
