MIDI UDF

Ascend4nt · July 27, 2013

czardas, nice to know we're helping you out! I'm just glad that I stumbled across that website, which lays out MIDI encoding really well. Might even be able to decode a MIDI file if that's the format of all messages..

I've also updated the script now to add Panning, Modulation, and per-Channel Volume adjustments. There's sustain pedal and aftertouch stuff added too, but I haven't been able to get them to work with my soundcard. I think it's just a limit of the drivers though.

Here's the script now, with more example stuff. I will need to separate the example stuff out for an 'official' release.

; ====================================================================================================
; <MidiExTest.au3>
;
; Extra Tests of the MIDI UDF (see below for best version)
;  This uses fixed versions of the functions in the original 'MidiTest' script,
;  especially MidiSetInstrument, NoteOn, and NoteOff.  It also adds a few functions
;
; Functions:
;    NoteOn()        ; Turns on a given note on a given channel at a given velocity
;    NoteAfterTouch(); Applies Aftertouch to a given note on a given channel at given pressure
;    NoteOff()        ; Turns off a given note on a given channel
;    PercussionOn()    ; Turns on a Percussion instrument at a given velocity
;    PercussionOff() ; Turns off a Percussion instrument
;    NotesAllOff()    ; Turns off all notes on a given channel (unless sustain is on)
;    MidiAllSoundOff()        ; Turns off all sound on a given channel (even if sustain is on)
;    MidiResetControllers()    ; Resets Controllers (Pedals, PitchBend, Modulation, etc)
;    MidiPitchBend()            ; Pitch-bends all the notes on a given channel
;    MidiChannelAftertouch() ; Sets Channel Pressure (AfterTouch) - different from NoteAfterTouch()
;    MidiSetInstrument()        ; Sets the instrument on a given channel (channel 10 is special though)
;    MidiControlChange()     ; Sends certain Control messages (such as Pan, Modulate, Volume)
;

Yeah, I struggled with this. As I say: the code I wrote recently was written with a view to doing things properly - using channels, even though I wasn't sure exactly how. I've had no time recently, but will resume development of my music projects when I find the opportunity. Here's a very cool link - it's definately worth a look. As far as I know there's a newer version of midi which includes features which may not be working for you; and it's also likely that they will not be supported by many other sound cards (it's a while since I read this, so the details are a bit vague).

Edited July 27, 2013 by czardas

czardas · July 28, 2013

You know, I never could understand the terminology used in midi. How on Earth did the term velocity get into the mix? No matter how hard I try, I can't find a reason to use this word in the context in which it's given. In air, the speed of sound is 340.29 m/s according to Google.

Edit

Now I understand how this turned out. The designers of midi decided that volume is a consequence of the speed your finger moves when it hits a piano key. I'm sorry: this is not only confusing, but also hilarious. Very well done to Ascend4nt for deciphering this. It has been a complete mystery to me until now.

Edited July 28, 2013 by czardas

Ascend4nt · July 28, 2013

czardas.. I never thought about the velocity term, as I've heard it used before in regards to sound. However, looking now I don't see any dictionaries that list it! Well, good investigative work, my friend.

Oh, I figured out that 'sustain' does in fact work, but it just so happened I wasn't realizing that it had to be applied, followed by note-off events, before its effect is noticed. i.e.:

; Sustain - This will continue keeping notes pressed even after 'release'
; (meaning after turning off the notes)
MidiControlChange($hMidiOut, $MIDI_CONTROL_SUSTAIN_PEDAL, $MIDI_MAX_VALUE)
; This normally turns all notes off, however with sustain 'pressed', they will continue playing
NotesAllOff($hMidiOut, 1)
; Disables sustain, and any notes turned off above will stop playing
MidiControlChange($hMidiOut, $MIDI_CONTROL_SUSTAIN_PEDAL, $MIDI_MIN_VALUE)

I think we need to revamp sandin's >Midi keyboard to allow for the use of all these extra controls, as well as percussion instruments, channels, velocity.. hrm, looks like a bit of GUI work which I loathe..

jaberwacky · July 28, 2013

From what I gether on the wiki volume and velocity are slightly different beasts. Wiki says this about velocity: "... a velocity value that indicates how forcefully the note was played ...". So it seems to me that I can have an instrument with a fixed low volume such as a synth that has been turned down to a low volume, then I could strike the keys forcefully all day and yet still achieve a low volume. Discuss.

AZJIO · July 28, 2013

Might even be able to decode a MIDI file if that's the format of all messages.

I too looked for this opportunity.

Ascend4nt · July 29, 2013

jaberwocky, Velocity as a concept does make sense when you keep in mind that the midi Out volume and channel volume work independently of the 'velocity', or how 'hard' a key is stricken. With touch-sensitive digital keyboards, the force you use to press a key is translated into velocity over the MIDI interface. This makes sense especially with weighted keys where you don't actually have to depress the key fully..

The official term is attack. Every note has an attack, a decay, a sustain and a release. The link also mentions the term (midi) velocity, but this is not standard music terminology.

Ascend4nt · July 29, 2013

I've updated the script again. I've now incorporated all the constants to use for controller messages, as well as the notes. I've also added more functions - one for channel aftertouch, one for all-sounds-off (overrides sustain etc), and a reset-controllers function.

There's additionally a 'velocity' value for NoteOff messages that I didn't have as part of the functions before. I'm not clear how this affects a 'release-key' event, but it is part of the MIDI message being sent!

These additions should expose most functionality of the MIDI interface, at least individual-message-wise..

I'll get around to splitting up the script from the example eventually. I should probably split the constants out too? Hmm.. I could also include an updated midiudf, which gets rid of the incorrect note-on/off values, and has faster DLLCall's (using a DLL handle),

czardas · July 29, 2013

Thanks again. This represents a great breakthrough for us all, I'm pretty sure.

MIDIEx UDF

Okay, enough time sitting on this. Here's the new MIDIEx UDF package, consisting of three modules:

MIDIFunctions.au3: This was the midiudf that Eynstyne created, except with all the fixes and adjustments made to it over time, plus the new functions that are still listed in a >prior post for MidiExTest.
MIDIConstants.au3: This has all the Constants that were originally part of the midiudf, but without the incorrect NoteOn/Off message constants. It additionally has these new constants:
MIDI Instruments constants
MIDI Note Constants (not NoteOn/Off, but note value)
DRUM (Percussion) Instrument Constants
Channel Constants
Controller Message Constants
MidiExTest - the same basic UDF in the >previous post, but stripped of Constants and functions that are now part of the other two modules

Here's MidiExTest as it is now, with proper includes and all. It's a lame example, but from this much can be done. There's plenty of examples of the midiudf that can easily be ported to this by adjusting the way Note messages are sent.

Is there a way to create a MIDI device wich is show in the device list in windows? I would like to emulate a MIDI foot controller.

Thx

JJC2 · August 19, 2016

I know this thread is old, but I'm working with MIDI right now and am successful at reading normal MIDI in messages.

But, the SYSEX part is not working.

For sysex to work, one has to use use MidiInAddBuffer (with a MidiInPrepareHeader created structure) actual, according to MS you need 2.

I did all that, found an example script on the German AutoItScript.de site.

But no good. Does anyone have a working example for SYSEX receiving?

Any help is appreciated.

I have re-written all buffer and prepare functions to be up to snuff with MS latest specs (both 32-bit & 64-bit) and provided ample buffers.

When I call MidiInReset(), I get MM_MIM_LONGDATA for every buffer, proofing that they ARE INDEED attached to the MidiInPort.

But there is no data in them, even though I know for a fact (MIDIOX shows it) that SYSEX is coming in.

I'm at a loss. Something is not adding up and I cannot figure it out.

James

ps. Code is attached. I must be doing something wrong with MidiInPrepareHeader (although it returns success) Sorry for it being long

Ditto that this is an old thread - but what are the alternatives?! Best to keep it all in one place. Unfortunately it looks like Ascend4nt has not been around the forum since 2014 and eynstyne hasn't checked in since 2013 (so I guess this great project is in the able hands of czardas?

Anyway, I've just started a project and I need a midi controller on my touchscreen laptop. I bought a DrumBuddy drum machine (amazing!) but the UI is not optimal for me (playing keyboards) so since it supports midi, I thought I'd whip up an app with buttons on it to control the device! I got the basic app to work but as I get deeper I need some help. For openers, it seems like I need to send a GM2-ON message which I believe is a Sysex. JJC2 says above that he has had problems with getting sysex to work. Anyone know the status on this? Also, how do I send a string of parameters for GM2-ON or GM1-ON (example: f0 7e 7f 09 01 f7 )?

la_saucisse · June 8, 2019

Hi,

(excuse my poor english, I'm french)

I tried this udf and create a small app that allow :
step 1 : display midi devices, choose one, choose midi out chanel : ok
step 2 : send a note : ok, it works, whatever on local (windows GS) or with an hardware expander.

step 3 : send a sysex... and this is where it gets complicated !
I guess I have to use the _MidiOutLongMsg() func, but 2nd parameter refers to _MidiOutPrepareHeader() func's return, and I can't find any documentation to explain it.
I tried the sysex message "as it" as parameter, but it failed.

any idea, anybody ?
