Multiple instruments, single project or multiple projects?

Christoph Hart

This is important as it will also show up as version of the compiled app / plugin. I'll add a safe check that requires to set this before exporting.

Excellent, that will help newbies like me :p

I've got this preset

<?xml version="1.0" encoding="UTF-8"?>

<Preset Version="1.0.0">
  <Content Processor="Script Processor2">
    <Control type="ScriptSlider" id="knob1" value="0.63"/>
    <Control type="ScriptButton" id="Save Preset" value="1"/>
  </Content>
  <MidiAutomation/>
</Preset>

But it doesn't do anything when I load it. It seems presets will only affect script 1 which is set to frontInterface.

Christoph Hart

Yeah, as I said, it just supports one front interface.

Check out this example:

0_1488794377602_Preset Example.zip

The second Script Processor is no front interface. Instead it uses a global object that contains the value for its knob which will be restored by the main interfaces' onControl callback.

This is a little bit complicated at first, but once you understand how it's connected, its a pretty easy procedure.

d.healey

Aha I get it now, thank you! It seems a little awkward though if you have a lot of scripts (like I do) and want to save the state of most of the controls in the preset. Can users overwrite or delete factory presets after the plugin has been compiled?

Edit: Just reread the blog post about these being read-only :)

d.healey

I'm struggling to find an efficient way to organise my preset handling script. I can see this being more suited to smaller instruments.

So I have my woowind .hip file and I'd like the user to be able to change between all of the different woodwind instruments. There will be at least 10 instruments and each one will have 10 or more samplers that will need to have their sample maps swapped as the preset is selected. Each will also need it's key range setting, modulator settings adjusted, and various behind-the-scenes knobs adjusted on scripts.

To hardcode all of this seems a very large task. I could add code to each script so that its values are stored in the userPresetData globals object (although it would be better if HISE did this anyway I think). But I will still have to write all of the sample maps into code, and if I want to add new sample maps I will have to edit the code again. Is there a more generic and automated way to populate the userPresetData object?

d.healey

What I'm finding is that by using the global user_preset_array idea I'm essentially building my own preset system for the instrument that works independently of the actual HISE preset system which seems a bit backwards to me. The only purpose of the HISE preset system becomes to change a combo box value. Is there no way the preset system could just take a snapshot of all of the controls, loaded sample maps, and the bypass state of samplers/modulators/etc. and then restore it when the preset is selected? This seems far more practical in the long term than having to construct this functionality individually for each instrument.

Christoph Hart

I'll have to disagree with you here. The idea of the preset system is to store snapshots of the main interface so that it recalls the controls. If your library allows to select different instruments that swap out multiple sample maps and adjust modulators and key ranges, then this is something you have to add to a combobox anyway.

On the other hand, adding support for changing modulators behind the scenes or swapping out sample maps for samplers directly opens up a parallel world which is disconnected from the main interface - do you get what I mean?

You might be able to reduce the complexity by generating the sample map IDs dynamically (which requires a consistent naming, but we'll agree that this is good to have anyway). Let's say you have :

a trombone
a trumpet
a flute
a clarinet

and each instrument uses sustain, release, staccato and portato samples.

then you could do something like this:

const var instrumentNames = ["Trombone", "Trumpet", "Flute", "Clarinet"];
const var articulations = ["Sustain", "Release", "Staccato", "Portato"];
const var hasPortato = [true, true, false, true];
const var keyRanges = [[40, 80], [43, 80], [56, 90], [50, 93]];

sustainSampler = Synth.getSampler( articulations[0]);
releaseSampler = Synth.getSampler( articulations[1]);
staccatoSampler = Synth.getSampler(articulations[2]);
portatoSampler = Synth.getSampler( articulations[3]);


inline function loadInstrument(i)
{
    sustainSampler.loadSampleMap(instrumentNames[i] + "_" + articulations[0]);
    releaseSampler.loadSampleMap(instrumentNames[i] + "_" + articulations[1]);
    staccatoSampler.loadSampleMap(instrumentNames[i] + "_" + articulations[2]);
    portatoSampler.loadSampleMap(instrumentNames[i] + "_" + articulations[3]);

    portatoSampler.setBypassed(!hasPortato[i]);
    changeKeyRange(i);
};

inline function changeKeyRange(i)
{
     // set the key colours for the given range in keyRanges[i]
}

In the onControl callback of the combobox you just have to call loadInstrument(value). The amount of needed strings is reduced from 16 to 8 here (and in your actual use case it would be 100 Strings vs. 20). Also, this collects all information into nicely readable arrays at the beginning of your script.

d.healey

Thanks, this makes it look a bit simpler and gives me an idea. I don't like having to hard code the sample map names, but what I'm thinking is if I gave the sample maps the same names as the containers and or samplers that they are to be used in then that would allow the .hip to be used for more instruments without having to keep editing the code. I could just read from the various module names.

d.healey

It seems like the group XF setup isn't saved with the sample map so switching between a sample map with for example 3 xfade groups and one with 1 causes issues

Christoph Hart

Yes this might be true (I didn't check yet, but on the other hand I didn't add support for this explicitely so it's likely to not work). I'll try to add this soon.

d.healey

I've built a little test script that should allow me to save and load the state of all simple envelopes with the user preset. My plan is now to add all the other envelopes and modulators so this is the only script I'll need to use to save all of my preset data in my projects. Before I embark on this though I want to know if you think this is the most efficient way to do it or if there is a better way?

Also is there a way to iterate over all of the controls of a script? Currently I can go through each one as an attribute but I have to know in advance how many controls the script has, it would be nice if there was a way to loop through them without knowing what number the last control is so I could neatly get every control's value into an array.

There is also the exportState and restoreState methods which export the complete state of a Modulator / Effect (including Table values and child processors) into a encoded String that can be used to restore data:

This example has an LFO that is resetted using a previously exported String every time you compile it (You can change anything, even add modulators to its chains and if you recompile it goes back to the original state).

Oh that looks like a better way to do it. Does this work script processors?

Christoph Hart

Yes. It does the same thing as copying a module with Ctrl+C.

d.healey

This is excellent news, I'm glad I checked in with you before I went any further :D

d.healey

The functions only seem to be available for Modulators and Effects, I get a function not found error when attempting export state on a Midi Processor.

const var script = Synth.getMidiProcessor("Script Processor");
script.exportState();

d.healey

I've put together a script using the export and restore state functions that will save all modulators and effects with the preset, the global userPresetData and the panel should be in whichever script is going to have the front interface of course but I've included them all in one script for the purpose of this demo. If we can have these export and restore functions working for scripts too then it will be really easy to use the preset system without having to hard code the saving and loading for each control of each script.

Alright I added the missing functions (along with the functions for restoring synths as a whole).

I also spent another tool that creates such a Base64 String from the currently selected module (Edit -> Create Base64 string).

This solution is not yet 100% clean because it recompiles the scripts which is actually not something you want when restoring presets. I'll have to change it so that the string only contains the content values.

It's commited so feel free to check it out.
