Convolution Samples Dropdown?

[Straticah]

Hey there i was wondering if it is possible to store the sample path in presets to recall them with a dropdown menu.
I want to give the user 5 reverbs to choose from. Any snippets that show how or if it works?

thx in advance :)

@Straticah The combo box value will be stored with the preset and in the combo box callback you can load the ir

@d-healey sounds good, is this how it is done? Or is there a more beginner friendly way since this is from 2018

@Straticah Get an array of the audio files, I think it's Engine.getAudioFileList() (check the API) and use the array to populate the drop down. Use the value (-1) of the drop down as the index to the array to load the file into the effect. I think the function is loadFile()

@d-healey rly have no idea but i will read step by step and maybe get somewhere, thanks a lot :)

@Straticah

Step 1: Get array of IRs using that Engine function I mentioned. file system API or Engine.loadAudioFilesIntoPool().

Step 2: Populate drop down from the array (I think I've shown this in a few videos, basically you're using a loop)

Step 3: In the combo box callback, load the IR into the effect. You get the IR from the array you got in step 2 and use the value of the combo box as the index (subtract 1 because combo box values start from 1 and arrays start from 0)

I created a convolution reverb based from impulse of my lexicon pmc60

See picture.

I Swap my IR with sliders with four positions.

Like David healey said I begin with this :

const var : convolution FX
const var : combobox

// Pool audio files
const audioFiles = Engine.loadAudioFilesIntoPool();
Engine.loadAudioFilesIntoPool();

// Reverb effects
const reverbs = [];

for (i = 0; i < 2; i++)
	reverbs.push(Synth.getAudioSampleProcessor("Convolution Reverb" + i));

// cmbImpulse
const cmbImpulse = [];

for (i = 0; i < 2; i++)
{
	cmbImpulse.push(Content.getComponent("cmbImpulse" + i));
	cmbImpulse[i].setControlCallback(oncmbImpulseControl);
}

inline function oncmbImpulseControl(component, value)
{
	local index = cmbImpulse.indexOf(component);
	reverbs[index].setFile("{PROJECT_FOLDER}" + component.getItemText() + ".aif");
}

After
const var : knobs
const var : Filename of IR in audio folder
Callback function for each knobs

// Panel 4  : size & time parameters for plate

const var Knob2 = Content.getComponent("Knob2");
const var Knob9 = Content.getComponent("Knob9");
const var Knob10 = Content.getComponent("Knob10");
const var Knob11 = Content.getComponent("Knob11");

const var reverbmap = ["plate_size1_time1 L",
"plate_size1_time2 L", "plate_size1_time3 L", "plate_size1_time4 L","plate_size2_time1 L",
"plate_size2_time2 L", "plate_size2_time3 L", "plate_size2_time4 L","plate_size3_time1 L",
"plate_size3_time2 L", "plate_size3_time3 L", "plate_size3_time4 L","plate_size4_time1 L",
"plate_size4_time2 L", "plate_size4_time3 L", "plate_size4_time4 L"];



Knob2.setControlCallback(Knob2CB);
inline function Knob2CB(control, value)

{
if (value == 0)
    {
cmbImpulse0.set("items", reverbmap.join("\n"));
cmbImpulse0.setValue(1);

	{

@Sounddiy That's some fun code you have there :)

[Sounddiy]

@d-healey I know

It is a mix of your's, others and peharps mine :)
