Hello,
long time no see.

I added hars for Pitch Bend and Program Change.

please try.

I added a boolean reporter block. It's used from Sensing blocks.

does it work with a launchpad mini mkII?

Hello,

I just open Web MIDI extension for Scratch3
It's Github page,

https://bit.ly/2I6Lvbz

Web MIDI API can only be used by Chrome Browser.

I start to study Scratch3 Extension.
So I can't fix some warning messages.
ArgumentType, I don't understand “id”.
Do you know there is detailed document?

Thank you

Scratch 3 MIDI is here.

Start guide for Scratch 3 MIDI

This is my memo.
I change scratch-vm and scratch-gui to “0.1.0-prerelease.20190711180933”
When I built Scratch 3 MIDI was Apr, 2019.
I found the usage of “menu:” was different.
I needed to correct my extension program.

I added Note On and Note Off command block with a channel, a note number and a velocity.

Great Job !
I have been waiting since January for this !
Eventually want it to work with Roland Go:Keys 61k
which broke when ScratchX was closed.

I have been in touch with hardware engineer for this Roland keyboard.

Alternatively a simpler less expensive is Akai.
Tested on Akai MPK mini play successfully but not sure whether program change is implemented !

Drums still internal after above tested.
Expect Channel 10 is used so will use Midi sniffer to see.

I will keep testing !
Roland Go:Keys 61k as external Midi is working as well as USB Roland UM-ONE to DIN 5 on same system.
I am not sure how to chose Midi Port in Scratch or Chrome.

See my project before modified to your extension.

define   
broadcast [ My thoughts for playing future songs ] and wait

Midi Note On (1) (Midi Chord[C major v] :: operator #ff8000 ) (127) for (0.25) beats ::#008800 // How would I play something like Midi chords for a beat duration ?

Instead of coding chords manually

Midi Note On (1) (60) (127) ::#008800

Midi Note On (1) (64) (127) ::#008800

Midi Note On (1) (67) (127) ::#008800

 Rest for (0.25) beats ::#008800

Midi Note Off  (1) (60) (127) ::#008800

Midi Note Off  (1) (64) (127) ::#008800

Midi Note Off  (1) (67) (127) ::#008800

Note: Roland Go:Keys plays chords and rhythms while sending real time Midi clock

Hello,

Aug. 4, 2019:
Before developing some requests, I added Beat Oscillator.
It's HAT block and it be set tempo, 30 to 240.

BEAT [tempo]::#0FBD8C hat 

Aug. 26, 2019
Ticks reporter and Rest some ticks command are added.
In this case, the resolution is 480 per beat.
Ticks reporter is reset at a measure.(=1920 ticks)

Aug. 31, 2019
The beat hat isn't need to connect to note sequence.
Because Rest command counts beats inside of the command.

Ticks::#0FBD8C reporter
Rest (240) tickes::#0FBD8C

Four quarter notes are described as below.

BEAT [tempo]::#0FBD8C hat 

forever
Note On (1)(60)(127) ::#0FBD8C
Rest (480) tickes::#0FBD8C
Note Off (1)(60)(127) ::#0FBD8C
Note On (1)(62)(127) ::#0FBD8C
Rest (480) tickes::#0FBD8C
Note Off (1)(62)(127) ::#0FBD8C
Note On (1)(64)(127) ::#0FBD8C
Rest (480) tickes::#0FBD8C
Note Off (1)(64)(127) ::#0FBD8C
Note On (1)(65)(127) ::#0FBD8C
Rest (480) tickes::#0FBD8C
Note Off (1)(65)(127) ::#0FBD8C
end

Sep. 2, 2019
NOTE ON command with duration is added.

NOTE ON (1) (60)(127)(480) ::#0FBD8C

Last numeric, 480 is duration.
the resolution is 480 per beat.
You can build 4 notes block as follows.

forever
NOTE ON (1) (60)(127)(470) ::#0FBD8C
Rest (480) tickes::#0FBD8C
NOTE ON (1) (62)(127)(470) ::#0FBD8C
Rest (480) tickes::#0FBD8C
NOTE ON (1) (64)(127)(470) ::#0FBD8C
Rest (480) tickes::#0FBD8C
NOTE ON (1) (65)(127)(470) ::#0FBD8C
Rest (480) tickes::#0FBD8C
end
