Our Progress on MuseScore 4 - Update 3
In this short post, I will outline our revised timeline for the release of MuseScore 4.
For anyone who has tried our nightly builds of MuseScore 4, it will be obvious that the playback sounds pretty strange (including a fun issue where VST plugins sound a half-step up from the default!). This is due to a large piece of unfinished work concerning the handling of playback data (dynamics, pitch, articulations, etc.). We had initially intended to simply reuse the MS3 system (which simply used MIDI events) but over the last few months have changed our mind.
Our codename for the new system we are building is MusePlaybackEvents. It will be an open event format that ensures the utmost precision when detailing the data required for high-quality and realistic playback, without losing compatibility with MIDI and VST. As I mentioned already, this was not work we had originally planned to do for MuseScore 4 but as we continue to experiment with higher quality samplers, we have come to realise that MusePlaybackEvents is a necessary investment right now. Not only will it open doors to take advantage of the full capabilities of our default (Fluid synth) playback, it will also allow us to build features that will provide exciting opportunities for VSTi's and MIDI 2.0 in the future too. We believe this work adds around 2.5 months to our schedule.
While this work is being undertaken, it has opened up some extra time for our engraving team, who have decided to bring forward some of the engraving changes we had originally planned for MuseScore 4.1 & 4.2. Some of these improvements are very significant and I'll be posting more about them shortly.
With that said, below is our revised timeline for the release of MuseScore 4.
We expect to be entering into our alpha phase once the MusePlaybackEvents work is ready in late December / early January
When we enter into our beta phase, we will have completed backend work on MuseScore.com that will allow members of the community to test uploads to MuseScore.com (this has previously not been possible and was something we felt we needed to address)
We expect to be releasing the external MuseSampler library midway through the beta phase so that the community can begin trying it out. This may very well materialise as a second beta release. It is worth noting that the expected size of the MuseSampler is 10GB.
We expect the release of MuseScore 4 around late March / Early April, 2022
Thanks very much,
