00:00:04,560 --> 00:00:09,511
Hi there, my name is Martin Keary and I'm
delighted to announce the release of MuseScore 4,

2
00:00:09,511 --> 00:00:14,449
a gigantic overhaul that touches on...
well, everything! Let me show you.

3
00:00:14,449 --> 00:00:18,350
First, it has a completely new look.
The light and dark themes have both

4
00:00:18,350 --> 00:00:21,264
been revamped and they have customisable
accent colours too.

5
00:00:21,264 --> 00:00:25,730
And for those with visual impairment, you can turn on
a customisable high-contrast mode.

6
00:00:25,730 --> 00:00:29,491
Along with the visual changes, we've spent a
lot of time improving the experience to help

7
00:00:29,491 --> 00:00:34,000
you find things more easily and notate
faster. For example, the top bar now contains tuplets

8
00:00:34,000 --> 00:00:38,670
and articulations and has many more options
that you can show or hide by clicking here.

9
00:00:38,670 --> 00:00:43,000
We've completely redesigned the Inspector,
which we've renamed 'Properties' and have

10
00:00:43,000 --> 00:00:46,000
added all kinds of little features and
improvements so that it's much more

11
00:00:46,000 --> 00:00:51,370
useful than before. It's also much smarter.
No matter how many things you select on you score,

12
00:00:51,370 --> 00:00:55,481
it will always be able to display relevant
options so you can change them quickly.

13
00:00:55,481 --> 00:01:00,621
We've also simplified the system for opening and
customising part scores. Select 'Parts' up here,

14
00:01:00,621 --> 00:01:05,000
choose the part you want and - using this
new instruments panel - you can show any

15
00:01:05,000 --> 00:01:06,857
accompanying instruments you'd like to see,

16
00:01:06,857 --> 00:01:11,000
rearrange them and alter their settings
too. And by the way you can also use this instruments

17
00:01:11,000 --> 00:01:17,520
panel to add staves or create linked staves,
which is really useful for guitar tablature.

18
00:01:17,520 --> 00:01:22,670
Now, here's a hallelujah moment for you:
MuseScore finally support the playback of tempo lines,

19
00:01:22,670 --> 00:01:25,483
like accelerando and ritardando.

20
00:01:25,483 --> 00:01:28,204
We've also improved the link with MuseScore.com,

21
00:01:28,204 --> 00:01:31,331
which makes it easier for you to save
your work to the cloud privately.

22
00:01:31,331 --> 00:01:35,093
You can then choose to publish your work on
MuseScore.com once your score is complete

23
00:01:35,093 --> 00:01:36,932
But we're only getting started.

24
00:01:36,932 --> 00:01:41,000
Next is the gigantic overhaul we've made to
our engraving. Sheet music in MuseScore has

25
00:01:41,000 --> 00:01:46,600
been transformed so that it's now highly professional
by default. One aspect of this is our new system

26
00:01:46,600 --> 00:01:50,676
for horizontal spacing. To give just one
example of how much this improves things:

27
00:01:50,676 --> 00:01:54,800
consider this notation from MuseScore
3 which now looks like this.

28
00:01:54,800 --> 00:01:59,578
We've also rewritten our systems for beaming, slurs,
ties and cross-staff notation.

29
00:01:59,578 --> 00:02:04,582
Apart from that the positioning of hundreds of 
different symbols are much better than before.

30
00:02:04,582 --> 00:02:09,000
Dynamics are positioned more accurately by default, You
can customize notation to have straight or

31
00:02:09,000 --> 00:02:13,094
traditional flags. We've added new notation
fonts, like Maestro and Broadway - and

32
00:02:13,094 --> 00:02:17,878
we've significantly improved and expanded
our own flagship notation font, Leland.

33
00:02:17,878 --> 00:02:21,627
But we're still not done because I've not
yet mentioned the biggest change of all,

34
00:02:21,627 --> 00:02:26,490
which is that MuseScore has an entirely new audio
engine and playback system. This has enabled us

35
00:02:26,490 --> 00:02:32,000
to support VST instruments and effects, which can
be assigned via our new mixer, like this. An even

36
00:02:32,000 --> 00:02:37,000
more exciting consequence of our audio engine can
be found by opening our new Muse Hub application,

37
00:02:37,000 --> 00:02:41,000
where you'll see something called Muse Sounds,
which is an orchestral plugin we've spent two

38
00:02:41,000 --> 00:02:46,000
years developing. Once Muse Sounds is installed,
playback will no longer sound like this:

39
00:02:58,329 --> 00:03:00,000
It will sound like this:

40
00:03:17,430 --> 00:03:22,004
It requires no customisation or
complex mapping to set up and it's free.

41
00:03:22,004 --> 00:03:26,200
MuseScore 4 is the result of a dedicated
collaboration between my team and the open

42
00:03:26,200 --> 00:03:30,000
source community, who provided us
with endless help on design and

43
00:03:30,000 --> 00:03:34,363
implementation as well as translations,
documentation and support for users.

44
00:03:34,363 --> 00:03:38,334
For those who want to get up and running as fast
as possible, we've released multiple tutorials,

45
00:03:38,334 --> 00:03:42,408
which can be accessed from within MuseScore 4
itself or by searching this channel.

46
00:03:42,408 --> 00:03:46,255
with MuseScore 4, we've now got the
sophisticated technical foundation we

47
00:03:46,255 --> 00:03:51,142
need to build new features with much greater
speed in future. There are a lot of big things coming

48
00:03:51,142 --> 00:03:55,425
soon and if you're interested in finding out
about them, please subscribe to this channel.

49
00:03:55,425 --> 00:03:58,000
Thanks a lot and take care!
