Default Add keyboard shortcut to an action programmatically

Hi all,

I want to programmatically add keyboard shortcut to certain action,
but it seems that there's no such a function in reaper_plugin_functions.h.

Previously I thought there's a function like this :

bool AddActionShortcut( KbdSectionInfo* section, int cmdID, char* desc, int desclen );

but unfortunately it doesn't exists.
Is there a way to do that ?


Many thanks in advance.

Default decode rpl format

Hi there,

I prototype vst plugins in faust and create a lot of creative presets on the way. I want to combine them in a rpl.

Can so help me decode this base64 string? I only get garbage when decoding these strings for a test plugin with only 1 parameter ("gain=1.0"):
Code:
<REAPER_PRESET_LIBRARY `VSTi: abc`
  <PRESET `Default`
    RZaZMu5e7f4AAAAAAgAAAAEAAAAAAAAAAgAAAAAAAAAEAAAAAQAAAAAAEAAAAIA/AERlZmF1bHQAEAAAAA==  //1.0
  >
I can automatically warp every preset in a vst plugin and import manally but thats annoying. There is also ardour2fxp.py which should do a similar job, but can handle only 1 preset.

Anyone?

TIA,
Urban

Many thanks in advance.
I think it's in Reaper extra API in the header "reaper_plugin.h" and not the "reaper_plugin_funtions.h"

Here's an example from an extension.
Code:
gaccel_register_t editMarkersAccelerator = {
	{FCONTROL | FALT | FVIRTKEY, 'D', 0},
	editMarkersAction,
};
There is also an example from the older Reaper extension sdk in the reaper_ninjamloop example.
Here's the link.
https://www.reaper.fm/sdk/plugin/plugin.php

Hope this helps.
Regards,
Wyatt

Thank you very much WyattRice !

I actually tried registering with gaccel_register_t with certain shortcut setting,
but I couldn't get good results.
It doesn't seem to register shortcut for existing action.
(I confirmed I can register new action and its default shortcut with gaccel_register_t)

But maybe my usage is not good... I'll try further.

Thanks !

There is nothing like the gfx thing in ReaScript available from the C or C++ Reaper API.

The simplest possible extension plugin code, that does nothing, but makes all the C API functions available, is something like :
Code:
#define REAPERAPI_IMPLEMENT
#include "reaper_plugin_functions.h"

extern "C"
{
	REAPER_PLUGIN_DLL_EXPORT int REAPER_PLUGIN_ENTRYPOINT(REAPER_PLUGIN_HINSTANCE hInstance, reaper_plugin_info_t *rec) {
		if (rec != nullptr)
		{
		   if (REAPERAPI_LoadAPI(rec->GetFunc) > 0) return 0;
                   return 1;
		}
		return 0;
	}
}
You of course have to set up a Visual Studio or Xcode project properly to build a dll for Windows or dylib for macOs to make that work.

Thanks. One more thing I stumbled with, I tried to add my own function as action and one as ReaScript-exposed function. I tried anything I could come up with, but Reaper didn't expose that, so obviously, I was using the plugin_register-function wrong.

So, could you please add to your example one hello-world-action and one helloworld-function, that returns the passed parameter-value(string for example) back?


Something like:
Code:
function HelloWorldAction()
   return "Hello World"
end

function HelloWorldApiFunction(string_parameter)

   return string_parameter
end

that are properly registered in Reaper? This would help me a lot with learning that stuff.

Actually making the plugin add working actions and API functions for ReaScript to use is quite involved. You for example have to implement the action handling callback yourself. Adding API functions requires lots of obscure boilerplate code per added function too. But I'll try come up with some examples. (You probably by the way meant the "hello world" action to actually print something on the Reaper console or show a message box instead of returning a string that isn't going to go anywhere...?)

edit : I made a new "minimal" example here that adds some actions (no API functions yet, doing that is so obscure I'll need to study again how that is done...You could look at Julian Sander's extension plugin for inspiration on that, though) :

Thank you.

And yes, I meant to use MB or something to print the HelloWorld


As far as I could see in SWS or JS-Extension-code, there's tons of stuff to do, that I don't understand as I can't get my head around the pure basics.
The more I can get into that, I'll try to write an introduction for new-coders to come up with at least a basic-plugin and documenting potential missteps and stumbling stones and how to set up XCode/VS to make it work at all.

For more complex stuff, like the action/function-register-management in SWS which is quite abstracted away to make stuff convenient, one needs to have more experience in C++ anyway, I guess.

Default JS: State Variable Morphing Filter

Hello,

it's about JS: State Variable Morphing Filter.

Can you show me a way to change the parameter "Frequency (Scale)"
from 0-100
to frequency (Hz) (like it is in ReaEQ)?

(There is a frequency-display already above the right box.)

I need it badly for lots of pitch-precise automation.

That would be REALLY nice!

I guess I needed some off-time, since I decided to do this. Added a Frequency (Hz) slider. You should still be able to use both Scale and Hz sliders.

Wow, thank you so much! How long did this take you?

[edit] Any idea why automation only works with the effects window open? And why the frequency jumps with a loud pop-noise when starting playback from a point where there is no pitch-change automation?

Honestly, since I wanted to have the both controls working, it took most of the time. perhaps an hour total.

Ha! So much for that solution... The way I got both controls working was to piggyback to the Scale slider. If the slider is not visible, it's not moving, and so isn't the Hz slider either. Just a moment, I'll kill the Scale option.

Managed to fix the dead-when-hidden issue. Automation even works for both Scale and Hz sliders, one at a time of course.

Didn't get it to pop on me.

I have been bothered by the "Scale" slider before, perhaps that's why I wanted to do this now that I (almost) can...

Is there a safe way to read it (by REAPER API or some simple call to VST .dll) if vst effect is an instrument or not?
A lot of PIZ MIDI FX are treated as instruments while they are simply FX preceding main instrument

As far as I've found is TrackFX_GetInstrument() which only detects first instrument in chain and can't be used to check for multiple instrument FXs

If it's specifically about PIZ MIDI FX, you can force them to appear as FX via tweaking pizmidi.ini (so it says there in the comments, but I never tried it myself).

Yeah, I knew somewhere deep inside this was the way but couldn't find the option.
For all the plugins, and not just PIZ, it seems it's there when you rename the plugin in FX browser where you can set it as an instrument or not.


Still, I do sometimes use two synths on the same track so the API solution, if ever developed, might come in handy. I have shortcuts and MIDI learns set to various scripts for disabling only non-instrument FX so would be nice to be able to differentiate between two different instruments on the same track

Post it into the Ultraschall-API-thread as Feature-Request and I'll look into that.

If something is possible, we can ask next question: Why is it not easier possible?

Example: IO drag to new track and you have your audio send. Similarly parameter drag onto another parameter could exactly do this, meaning activating parameter modulation, selecting link, then assigning from > to. 3 steps in one, would it be possible? Of course. If developers want it. It would just add one more simple drag and drop action then using all the functions which are already there, giving them preset values: parameter modulation, link, target. And this would feel almost like bitwig, if not better. Know it only from youtube videos, never tried bitwig.

Nope, not possible with the GUIs of 3rd party plugins. The host application has no idea where the parameter controls/knobs are in the plugin GUI or what they are. (So operations like mouse dragging won't work.) For Reaper's own Rea plugins it would be possible to implement, though.

But there is an option to switch to normal slider view and there it could work.

That’s what feature requests are for, for the devs to learn what the users want. Maybe make one?

I agree, the feature is well hidden. I do see an issue with dragging a slider to another track though, since the point of sliders is to be dragged, for the control itself. And holding additional keys is for precise, group dragging etc, and impossible to remember unless used constantly. But right-clicking a slider might be an option for this, and perhaps other features as well.

Default Gaussian LowPass

Hi

I thought Id have my first try at making a JSFX-plugin. Its gonna be based on a Gaussian Distribution and therefore needs to look a number of samples both ahead in time and back. I dont think its been tried before and it might sound really cool.

The idea is pretty clear in my head but Im bad at writing actual code. Im doing this so I can learn. And if you guys would be willing to walk me through this. It'd be very much appreciated. I literally dont know where to start.

So to get up and going. Lets start with averaging a number of samples. Lets say nine: Five back in time + four ahead of time. Wich I guess would have a lowpass effect around 5.3 kHz ( 48 kHz / 9 ) if my math is correct....?!?

How would I do that?

Thanks and best regards /Bo

While I’m not very advanced myself, I’d like to try and help. But I really don’t know how, or where to start.

Hi. Thanks for clarifying that

My experience with code is surface level tinkering with bits of existing code. Mostly HTML, CSS + PHP. Wich means that I can spot the parameters in a code where I need to change it. I can copy + paste bits. I can understand a flow chart for code and what its functions are. But writing code from scratch is beyond me.

I have looked at JSFX-code and changed some parameters in a couple of Reaper plugs to better fit my requirements. But thats it.

================================================== =================

Back to the Gaussian Filter. Ive included two different graphics. Theyre hopefully better illustrations of averaging samples ahead + back in time. The "Gaussian-Filter-2.png" is to show the end goal of the idea. And "First-Filter-2.png" is to show my first goal post for it and check if it actually works as I intended.

This comes from years of working in photoshop with blurring and sharpening images. Wich is essentially the same as reducing or enhancing treble. Some types of blurring are sweeter looking than others. As with sharpening. And I think the math for that can be adjusted + applied to audio as well. Hopefully with interesting results.

An extension of this could be a Laplacian Distribution or Edge Detection Treble/Air Enhancers. Maybe Side Chained Matrix Filters. Wich again. If it works would sound very cool.

Best regards /Bo

PS. BTW. I love the Mrelwood KickbAss DS

Ok, you're already at a good start! The idea is interesting and I have no idea how it would sound. Let's make this happen!

What you need is to store samples for later use, and set a Plugin Delay Compensation value. LOSER's great "Zero Crossing Maximizer" has both.

What the Maximizer does is it writes the current sample value to "buffer[bufpos]". At launch both are at zero, so the memory slot written to is 0+0. Near the end of the code a one is added to "bufpos", so the next sample goes to mem slot 0+1, etc. Once "bufpos" is larger than "bufSize", "bufpos" goes back to zero.

At this point we have as many samples stored as the "bufSize" determines. Now you just average the samples starting from "buffer[0]" to "buffer[bufSize]" and put out the result.

In order for the result not to come out a full "bufSize" too late, the plugin must set the PDC. In the Maximizer the "bufSize" is adjustable, so it is in the "@slider" section.

The basic structure of a JS plugin and all the relevant functions are explained in the reference guide, although it is a difficult read for a beginner:
https://www.reaper.fm/sdk/js/js.php

Let me know if you were able to follow what I wrote and let's find out what kind of assistance you need next.

Thanks, that's nice to hear! You know, I think you are the first to spell the plugin title correctly!

Cool. This is exactly the info + level of support I was looking for
I had a quick look but need to delve deeper into it. Be back as soon as Ive gotten me head - a bit more - around it.

Kiitos /Bo

Hi

A tiny update. I managed to stumble upon LOSERs Jesusonic Tutorials. So now Im working my way through that. Fiddling with the parameters of the delay + marinating in how the code works.

Question 1: Regarding bufpos. Why is it buffering +1 samples til it reaches the specified parameter and then executing. Instead of buffering specified number of samples, and then executing at the right time? Is that just the way DAWs work? One sample at the time?

Question 2: The info in the right column of the Code Editor? Are those all the available functions in JSFX? Or a selection? See attachment

Best regards /Bo

Didn’t know such exists, I better check them out as well!

Exactly. Reaper reads the value of the next sample in the audio file and gives it to the plugin as values in parameters called ”spl0” (left) and ”spl1” (right). The plugin updated the ”spl0” and ”spl1” values, and reads and executes all code in the @sample section. So that section is executed 48000 times per second, for every new sample. (Or whatever the samplerate is set to.)

Other code sections:
@init - is read only at plugin load, srate change, and depending on settings at playback start/stop.
@slider - is read only when you drag the plugin’s slider with the mouse.
@block - is read at every audio buffer start, so every 64-2048 samples, depending on the audio buffer size.
@gfx - is executed max 30 times per second, depending on how hard the computer is working.
The section before @init is only read once at plugin load. Sliders and some options are set there.

Not exactly, they are all parameters in the plugin code. If you set ”myage = 128;” in the code, it will show up on the right. You can filter the list by typing ”age” at the filtering field below, then the list will only show ”myage”, ”yourage”, ”cages” etc, if you have them set in the code. And who doesn’t, right? ;o)

Default Getting to grips with JSFX

Hi

So I managed to take a millisecond based delay and convert it to note length. However it wont start with the set delay value. It defaults to zero. Im guessing its the @init that needs the right instruction? I tried some different things but to no avail. What should it say?

Also. Are there other ways to get note length values other than from sample rate and bpm?

Thanks /Bo

desc:Mono Tempo Delay
slider1:0.5<0,2,0.125>Length 1/4 note

@init
bufpos=0;

@slider
echolength = srate * (60/tempo) * slider1;

@sample
bufpos[0] = spl0 ;
bufpos = bufpos + 1 ;
bufpos > echolength ? bufpos = 0;
spl0 = spl0 + bufpos[0] ;
spl1 = spl0 ;

The issue with the delay happens because the "tempo" is not yet assigned during @init, and based on my testing not even at the first execution of @slider. So the echolength is calculated for a tempo of "0".

I don't know why tempo is zero during @init. But because of this the first calculation of "echolength" must happen either in the @block or @sample sections.

I'd like to introduce "user functions", as I would solve this with one:

Code:
@init

firstrun = 0;
function getlength()(
  echolength = srate * (60/tempo) * slider1;
);


@slider

getlength();


@block

firstrun == 0 ? (
  getlength();
);

firstrun = 1;

tempo != tempo_old ? getlength();
tempo_old = tempo;


@sample

// Copy from the original code

- In the @init section we assign the function "getlength".
- If the slider is used, we again just call the function.
- In the @block section, if "parameter "firstrun" is zero, we call the function.
After that we assign "firstrun" to be "1", so the @block call is not executed again until the "firstrun" is reset.
- I also added a condition in @block which if the tempo changes, calls the function.

Hi. Pardon the late reply but Im traveling and the internet is real slow

Im not sure what Im doing wrong. Ive had issues with the plugin seemingly not updating. And I get this error message. See attachment

Regarding the tempo timing? Would the beat-parameter useful? As opposed to calculating from BPM and samplerate to milliseconds?

Kiitos /Bo

Ah, that one’s on me, sorry! The error message tells us that there is an invalid character ”)” at row 22 in the @block section. Last row in the @block section has a closing parenthesis that has no opening parenthesis to be closed. I usually put one after the question mark like this: ”? (”
That would fix the error, and the code should (hopefully) execute.

Nothing wrong with how the timing is currently calculated. ”beat_position” is not very helpful for this purpose.

How can I get the empty-part of the TCP, it's position and size? Breeder did it in SWS for the GetMouseContext-function, but I couldn't understand, what he did to make that happen.

My CPP-knowledge is still too bad for that... :/


And another thing, that came into my mind, maybe interesting for SWS:
Currently, there's no possibility for extension-stuff in the VideoProcessor or JSFX.
Could we use gmem to overcome that?
SWS monitors certain things in the background and constantly updates a gmem-state, that can be accessed in JSFX/Videoprocessor or something, where SWS defines gmem-names.
Or maybe sending "commands" to SWS that way to make things happen, that are usually outside the scope of JSFX.

Though I don't know, if gmem is accessible from C/C++ at all...
