Per voice pitch scripting

[jukea]

Hi,
I must be missing something obvious in the way the sampler work, but I can't manage to script the pitch. For example, in his case I'm trying to alter the pitch of the sampler voices by a random factor:

The note gets played, but its pitch is never altered. Can it be done ? Am I doing it wrong ?

The scripted modulators work in a different way to normal MIDI processor scripts and require different commands (I don't fully understand them). I think you can use your script from a normal MIDI processor though.

i tried moving function onVoiceStart(voiceIndex) in a script node, but it never get called. However, it does if it's part of a pitch modulator script. In that case, the Synth.setVoicePitchValue(voiceIndex, pitch);
seems to do nothing.

Just return a value from 0 to 1 from the function, the rest will be taken care of - the modulation intensity will be applied to the value and it will be converted to the correct range (in this case 0.5 ... 2.0).

function onVoiceStart(voiceIndex)
{
    return Math.random();
}

Hm, I'm still missing something it seems. I did exactly as follows :

• started HISE
• created a sampler
• dragged a wav on some note
• open the pitch processor
• added the code in voice start
• clicked compile (no errors)

When I click the note on the keyboard at the bottom, the pitch is always the same.

Have you set the intensity to something > 0? A script modulator is just like any other modulator and needs a intensity to work.

Thanks, works perfectly.
