ChordGun (tool for inserting chords and scale notes)

[St3v3]

Thank you!

[Harry Diddlebock]

High. Hell oh. Reading the comments in this thread, this ChordGun script seems highly rated or at least very useful.

But how do I download GunChord if I can't install ReaPack on my Windows XP computer?

Is via ReaPack the only way to download ChordGun?

I did download ChordGun.lua from https://github.com/benjohnson2001/Ch...r/ChordGun.lua but it doesn't work.

If possible, can someone please upload a working version of ChordGun to the REAPER stash?

Is ChordGun's filesize too big for the REAPER stash?

[matv]

I guess you'd need the other files in the repository.

The master branch is unpackaged and untested, don't use that

Everything is available in the pkg folder of the release branch, the main action is here https://github.com/benjohnson2001/Ch...t_ChordGun.lua

I managed to get ChordGun working.

I don't know how to download a lua file from that site via my ancient Firefox browser.

So, I just copied the code into notepad and changed the txt file extension to the lua file extension.

I checked to see if YouTube has videos about ChordGun... and yes, there's a few of them that I plan to watch later to find out how to use ChordGun.

Thanks very much PandaBot for helping me find the proper ChordGun to download.

Hi, very eager to try this but having issues as well. I got the pack from ReaPack browser within Reaper. The problem is pressing on the chord buttons does not input anything into the midi editor.
Appreciate help to get this working.

Edit: To clarify, it works in sending chord events to a VSTi when I have record enabled and MIDI input set to virtual input. But I still cannot get it to work for inserting events into midi editor (non-recording mode)

Did you try holding the shift key while clicking the chord name?

unfortunately it is not possible to detect when a key is released, although I came up with a hack that seems to work on my machine (note offs are detected with just a small delay). The problem is that it relies on a number that you have to tweak before it works right, and this number is likely different for each user's machine so decided against implementing it for the general public

I would love to be able to trigger the chords from one octave of my MIDI keyboard, but with note-off being observed.

Is there any workaround to be able to do this? Like a JSFX script that detects the MIDI notes and then alternately triggers the "scale chord n" and "stop all notes" actions?

Thanks anyway for a great tool!

Couldn't get midigun to work,I have scaler which is easier for my brain,just add it to the start of an instrument.

It costs though but not much.

I tried this,no sound at all.

I use Scaler so no biggie.

This tutorial does not explain how to get sound from it and yes I have Air's Mini Grand plugin installed into a midi track and armed and making sound on my midi kb.

Where is Kenny G?

[smasha]

Got it to Work!

Make sure you have all midi channels selected on midi in.

I'm old and a dumbo,God hates us ,we struggle for stuff brainiacs find easy.

[bobobo]

"Insert virtual Instrument on new track" do the trick at once

I never looked into any JSFX stuff so I'm not sure if that's possible, it looks like these guys explored that a little https://forum.cockos.com/showthread.php?p=2182487

Hi, can you tell me where in Reaper i can find the ReaPack browser?

[pandabot]

It's in Extensions->ReaPack->Browse packages

[bobobo]

thank you this cool enhancement to REAPER



i have the same issues like Xenova
https://forum.cockos.com/showpost.ph...6&postcount=53

Ctrl , Ctrl . and those others won't fire the action

i tuned the Chordgun a little to fire decrementScaleTonicNoteAction() with a , solely .. and that works

downgrade to version 1 (i kind a like the non shift thing, but democracy rulez)

the detection of control/command/shift-keys seams to be defective in windows

i see the detectiojn of control in variable gfx_mouse_cap

32 for the Logo-Key (Windows),
8 for shift
Ctrl is 4
Alt is 16

WindowsKey with comma shows preview of desktops
and WindowsKey with dot shows an emoji-selection

--

i see that inputcharacter won't change if Control and Comma are both pressed .. shift will work but changes the inputcharacter from 44 to 59 (normal behaviour)

[STOP]

Thanks Pandabot for your excellent ChordGun.

I replaced the chord Root-5 (C-5 in C) for minMaj7 (label it min+7) chord cos I need that chord in harmonic mineur mode.

Oh interesting, that's not what I would have expected from reading the docs:

gfx.mouse_cap is a bitfield of mouse and keyboard modifier state.
1: left mouse button
2: right mouse button
4: Command key
8: Shift key
16: Option key
32: Control key
64: middle mouse button

You can probably disable these global hotkeys in your Windows configuration and then it should work. So I guess the translation is:

Mac command => Windows ctrl
Mac option => Windows alt
Mac control => Windows logo-key

[bobobo]

I understand the gfx.mouse_cap

Control is Windows Logo Key
Option Windows Alt Key
Command is Windows Control Key

But command/control/alt & comma/point is not recognized by the script

inputcharacter won't change then

But maybe my pc is crap

I wish one of our script heros would check this

[pandabot]

inputCharacter is not supposed to change when modifiers are held down, modifiers only change the state of gfx.mouse_cap. The script checks to see if these flags are set using these functions https://gist.github.com/benjohnson20...d25bbb7bc241a4

The Windows logo-key shortcuts are global and will override this script, that's the real problem. It should work if you disable these

[bobobo]

i 've diable shortcuts
but the script wont recognize , . with those modifier keys

i dont want to spoil my pc (windows an windows-Logo-key isn't that easy to switch off, you have to crawl into the guts for it)

maybe someone with Windows can confirm it or show the way what i do wrong here.

it still keeps being a great script

[bobobo]

i've found maybe similar issues concerning gfx.getchar

https://forum.cockos.com/showthread.php?t=212238

there is a script that shows what key is pressed.

, and . (and other with no regular key) shows values as long as Commd / Alt or WindowsKey isn't involved, if they are no value is shown.

the code in handleinput is ok but delivers no result

(can only test in Windows)

Anybody here who can confirm this?

[bobobo]

how about a version that uses
0 - stop all notes from playing
1 - play scale chord 1
2 - play scale chord 2
3 - play scale chord 3
4 - play scale chord 4
5 - play scale chord 5
6 - play scale chord 6
7 - play scale chord 7
q - higher scale note 1
w - higher scale note 2
e - higher scale note 3
r - higher scale note 4
t - higher scale note 5
y - higher scale note 6
u - higher scale note 7
a - scale note 1
s - scale note 2
d - scale note 3
f - scale note 4
g - scale note 5
h - scale note 6
j - scale note 7
z - lower scale note 1
x - lower scale note 2
c - lower scale note 3
v - lower scale note 4
b - lower scale note 5
n - lower scale note 6
m - lower scale note 7
cmd q - decrement scale tonic note
cmd w - increment scale tonic note
cmd e - decrement scale type
cmd r - increment scale type
cmd a - halve grid size
cmd s - double grid size
cmd d - decrement octave
cmd f - increment octave
cmd y - decrement chord type
cmd z - decrement chord type (in german version)
cmd x - increment chord type
cmd c - decrement chord inversion
cmd v -increment chord inversion
cmd g - cursor one step right in grid
right arrow - cursour one step right
left arrow - cursor one step left
F1 - this help

you can download 2 variations
english version directly from here
normal version

german version (z and y are reversed)
german Version

put it into the scripts folder Scripts\ReaTeam Scripts\Various\pandabot_ChordGun

load it in the action list.

Hey very nice! Yeah it should be pretty easy to hack, adding custom scales is a similar process if anyone is curious https://imgur.com/a/V01ovbI

[Eisenspalter]

Nice smart chord helper. I have the problem, that the chords always play forever. I know I can press 0 to stop all midi notes, but that makes no fun. What is the problem in general, and is there a work around?

There's no api access into key releases so there isn't any way to tell if a user releases a key. I was playing with a workaround here but it wasn't a good solution

If you optionally set a note length beforehand and compare the current key with the previous key, and only play a new note if the key or chord is different, that would be a great improvement. And I could work with it well.

[pandabot]

So instead of having everything ring out, the duration of the chord/note should be the same as the grid length?

[Eisenspalter]

Sure, you can use the grid length

[bobobo]

And the actual temposetting.

A grid set to 16 at 220bpm is shorter than 16 at 66bpm

Maybe it`s easier to set a diable length in seconds or parts of seconds in realtime. Note-on with a countdown til note-off

I remember doing that, if you look in the code there's a Timer class that ends up being unused but that's what that was for. I can't remember why I didn't go with it, it was either less satisfying than having it ring out or too small a benefit to justify the added complexity.

Most interesting melody lines require more than one subdivision, so with this change you'd probably have to set the grid to a larger value and then get the shorter values by playing the longer one immediately after it unless you're unnaturally good at switching grid value while playing. And that's assuming you make it monophonic. Even with this change the playable rhythms you'd get for interesting melodies are pretty limited. Since the API doesn't relay key releases we can't really create playable computer keyboards so I end up just using ChordGun as a harmony tool and then add the rhythm manually afterwards.

Maybe if enough people ask Reaper devs for API access into key releases they'll add it! I just worked within the limits, I don't know if anyone has even asked yet

Frist of i think Chordgun is a great addon!

But proably found a bug:
When i inserd two or more chords via shift and clicking on the wished chords i always get fast forward sound of audio i recorded if there is audio in the same bare in an other track.

would be glad for an answer or how to fix this,
Thanks

[pandabot]

Hey that's pretty weird! It seems to be a bug within the "reaper.SetEditCurPos2" function where if you move the cursor forwards in time twice then Reaper thinks it should be playing audio like normal (at the lightning speed of cursor jumps)

I figured it might be the combination of playing the chord and moving the cursor, so thought I could rearrange the order of the functions to try and fix it but it still happens even when I removed the audio-playing part of the code completely. I don't think there's anything I can do, the tool needs to be able to set the edit cursor after inserting a chord so you can be in place to insert the next chord after it.

As a workaround you can solo the track while entering chords. Also feel free to file a bug report, both "reaper.SetEditCurPos" and "reaper.SetEditCurPos2" have this behavior

All the ChordGun functions are available as individual Actions, it might be possible to somehow map midi notes to trigger reaper Actions but I'm not sure

Yes you can assign these individual Actions to keyboard shortcuts, and there are also keyboard shortcuts for when the UI has focus. For chords use the number keys 1-7 and 0 to stop the notes from playing

Ah, that is a cool design then, yes you can map also midi notes to actions, of course, even osc events. Advantage of midi mapping over qwerty keybinding is, it works always, no matter which window is active/focused.

I want it,.. Im sold..

How do I install it?

edit: I figured it out, thx to Jon@Reaperblog...
