Is there a MIDI plugin that plays + holds a MIDI note?

[reapercurious]

need a midi plugin (jsfx or otherwise) that simulates a midi keypress being played even when the transport is stopped. to use in combination with reasynth to generate a tone without needing to write midi notes, create loops, and pressing play.

know of one?

[DarkStar]

Ctrl+click the Virtual MIDI Keyboard

[reapercurious]

you know how if there is a white noise generator plugin on a track, it plays constantly? i want a plugin that will act like a held key on a midi controller regardless what you do in the project, whether its playing or stopped, as long as the audio device is on.

the virtual midi keyboard stops working if you open the FX window on the synth's track.

thank you for your reply Darkstar!

How about just putting the noise generator plugin on a track and automating the track mute.

How do you intend to control the on/off of the generator, with a midi keyboard?

thanks for your reply,

here it is in a nutshell... simple plugin that "holds a finger" on a "virtual" key that sends that midi note (at a variable velocity) to a VSTi synth or an outboard MIDI controlled synthesizer, Eurorack, etc.

Purpose: creating drones in order to do sound sculpting, making pad presets on a synthesizer, doing sound art, etc.

It should function independently of the play/stop controls of the transport.

So there needs to be a midi channel in reaper that is free from association with the transport first.

"reapercurious :So there needs to be a midi channel in reaper that is free from association with the transport first"

No... that´s not the prob.
you only need one track that is REAPERs CC#123 Spam free.

for example use
Plug Chain:
JS:
1.// MB MIDI Event Filter2
and filter out CC#123

than
example:
JS:
2. MIDI Note Hold

3. "Your Synth"

and now you can simply trigger your endless note with Record/monitoring on and
"DarkStar: Ctrl+click the Virtual MIDI Keyboard "
or without Ctrl

and you have your endless playing sound for editing or whatever during Play and Stop mode and from Play to Stop or Pause mode......
It stops (only) autom. if you press start the next time or from Pause to Play..

--
Of course only without any flush FX on stop on...

on the old hardware, we used to just use tape to hold down the keys across the octaves. in the piano roll editor, just draw in some breves or whole notes and drag their endings out longer.

Can you edit the JS: MIDI Note Hold to hold more than one note at the time so you can use it to play a chord? Or is there some other VST that lets you do that?

[TonE]

Who wants to buy a nice small keyboard which can do this: k-board, activating its "Togl" button (greed led), there you have your continuous notes. As many as you like, each note can be added and removed, create any chord drones you want. Perfect for sound design for example.

Another related technique if you want to improve/adjust/finetune your fx settings. Hold notes, as above, then add an fx which can do "random hand movements" on one or multiple parameters, so you can hear a range of possible sounds. While this happening in the background you can finetune your fx settings. (How much or little, where to set their limits, min and max per parameter).

I found a plugin that does this, it's called Midi Latch and can be found here: http://www.midikarval.net/_mgxroot/page_10763.html

Unlike the JS plugin it can hold several notes.

That's cool! This is an old thread but "taping down keys" is still a thing these days

I've been looking for a plugin like that for a long time, I've found a couple of other ones too but there was always some problem so they didn't work properly.

Midi Latch can also be combined with a plugin called Midi Drawbars on the same site which lets you play one or more octaves and chords just holding one note. The developer just upgraded both plugins to both 32- and 64 bit as well.

This should work in a JSFX:

desc:MIDIGenerator

slider1:note=60<0,127,1>note
slider2:vel=80<0,127,1>vel

@init
playing = 0

@slider
playing = 0

@block
playing == 0 ? (
  midisend(0, 0xB0, 123); //Send all sounds off
  midisend(1, 0x90, note, vel); //Send note on
  playing = 1;
)

[souk21]

And for MIDI latching this should work:

desc:MIDILatch

slider1:octave_m2=0<0,1,0.1>Octave -2
slider2:octave_m1=0<0,1,0.1>Octave -1
slider3:octave_p1=0<0,1,0.1>Octave +1
slider4:octave_p2=0<0,1,0.1>Octave +2

@init
notes = 0;
memset(notes, 0, 127);

@block
function switch_note(note, vel) (
  notes[note] == 0 ? (
    midisend(offset, msg1, note, vel);
    notes[note] = 1;
  ) : (
    midisend(offset, 0x80, note, msg3);
    notes[note] = 0;
  );
);
function send_octave(note, vel, pitch_offset, slider_value) (
  slider_value > 0 ? (
    switch_note(note+pitch_offset, vel * slider_value);
  );  
);
while(midirecv(offset, msg1, msg2, msg3)) (
  msg1 & 0x90 == 0x90 ? (
    switch_note(msg2, msg3);
    send_octave(msg2, msg3, -24, octave_m2);
    send_octave(msg2, msg3, -12, octave_m1);
    send_octave(msg2, msg3, +12, octave_p1);
    send_octave(msg2, msg3, +24, octave_p2);
  );
);

  );
);

Wow, I just saw these, will try ASAP! Thank you.

I'm working on a plugin right now and on the first test it incorrectly held all the notes and ignored note off messages besides. That makes me somewhat of an expert on this type of tech!

Switch_note's structure looks like an excellent basis for something I'm doing and direly need to refactor; I was close to doing it that way but somehow wasn't seeing the obvious. Thanks!
