Musescore 4: Where have all the ...MIDI controls... gone?

• Aug 21, 2022 - 10:19

In the MuseScore 3 mixer, there were a few MIDI and other things one could do for each staff/track - see the read rectangles:

Where have they gone in MuseScore 4?:


  • I'd need at least the MIDI channel urgently ... Thanks!



>>we have not been able to carry over the systems for mapping and prioritising sounds from MS3.
I'm anxiously looking forward too, my speculation would be devs are building new "track/channel" system from scratch, it'd be interesting to see how the new logic would tackle things like 3 individual VST tom drums plus others fitting into one drumset or how violin and viola shares one pizz sound.
peek into codes for uptodate developement
why not use v3? afaik all that on the right like reverb chorus has not been working anyway. am i correct?

>>why not use v3?
Because v3 has huge problems with its long "reset event sequences" (see; v4 seems to be much better:
* If I play BRM music's great score of Sousa's Lambs March with v3 on my computer, the intro is completely garbled, because the MIDI engine seems to play catch-up with the events that overwhelm it (two CPU cores are running at their limit).
* In v4, the same score plays flawlessly on my computer, with the CPUs more or less idling along.
Thus, I wanted to compare MIDI playing in some more detail - but for this, I need some more finegrained control over what goes to which MIDI channel.

Incidentally, the musical playback of the Sousa score is quite a lot worse in v4 than in v3 - I want to give feedback on this also; just not finding enough time right now.

Hello everybody!

Taking advantage of this topic, I would like to know what the synthesizer would look like in MuseScore 4 so that we can change instruments as we currently do. Will it be possible to enjoy all sound fonts that are not native to MuseScore in version 4? All plugins available on the site that work correctly in MuseScore 3, work or would they work normally in version 4?

Thank you friends!

Changing instruments is done fromStaff/Part Properties just as it always has. The Synthesizer window isn't for changing instruments, but instead, for changing soundfonts. In MuseScore 4, it's pretty unlikely anyone will still want to use soundfonts because the new Muse Sounds library will be so much better than any soundfont could ever hope to become - that's what we keep hearing, anyhow, and I'm choosing to believe it! But, if after using MsueSounds you still find find a need for an older soundfont also - perhaps for a less common instrument only available in some specialty soundfont - you'll be able to select soundfonts via the Mixer.

Plugins are still a work in progress. The initial release of MuseScore 4 will only support a limited set of plugins, but that should be addressed soon after.

Hello Marc!

Thank you so much for your wise guidance! Improved sounds are great news, so we no longer have to look for sound sources.
From what I understand, the Muse Sounds feature will only be available after the official release of "MuseScore 4", am I right?

Regarding plugins, I understand that MuseScore 4 would already have the features of many existing plugins. That is, the work of many plugins would be aggregated in the tools to MuseScore 4, is that it?

Big hug friend!

Muse Sounds should be available before the actual release of MuseScore 4 - it should be available in the beta, expected very soon (within the next few weeks). But it won't work with older versions of MsueScore - so, you wouldn't be able to use it with MuseScore 3. It's just a totally different technology from soundfonts.

Regarding plugins, which opens specifically are you interested in? I don't know that there are any new features in MuseScore 4 that would replace things that used to require plugins, except one very big one: "Tempo Changes" will no longer be needed, because "rit" and "accel" will be supported directly.

In reply to by mjbartemusica1

Of these, new retrograde is one of the plugins that will be provided by default and will hopefully work by the time 4.0 releases. Tempostretch shouldn't be needed as much now that rit and accel are supported directly, even though I realize that is more about tempo changes than tempo stretch. The functionality of batch convert is also achievable with a shell script / batch file. For the others, you will probably need to wait for 4.1 or some other future release to be able to use them. Note that at least some of what prunestack doies, is done more easily by Tools / Explode.

In reply to by mjbartemusica1

Actually as far as I can tell batch-convert works in MuseScore 4 as is, even if it isn't fully adjusted (some of the more obscure/newer file formats are missing or too much/wrong).

It does require a score to be open though, unlike MuseScore 3 and 2 (but like in MuseScore 1), seems the requiresScore: false setting is ignored/not working
