Global velocity modulator issue

Christoph Hart

So this looks like a workaround, but it's actually quite OK:

So basically what happens is that I am using the event's gain property to communicate the velocity response of a script processor's table down the line (check how I used the Engine.createAndRegisterTableData() call in order to make a scripted table accesible to the main interface so you can still defer it). Then in each target sound generator, I am fetching the gain value and calculate the respective velocity for it. As long as you never use the original events (which you don't if I understand this use case, you should be fine).

d.healey

@Christoph-Hart Thanks, I'll check out your example

d.healey

Your example works, but I have another caveat :p

The way I'm mapping my samples is like this

I'm separating the guitar strings, rrs, and up/downs using velocity, and separating the dynamics across the playable range. So when I play my artificial notes I need to be able to control the note number and velocity regardless of what the user actually played. But I still need the real velocity to be passed to the gain mod. I thought the global modulator would take the real velocity, since it's before the scripts, and that's what I'd get at the gain target.

I know I could use another mapping system, like one group per string but that's going to end up with a lot of groups when I have lots of articulations and rrs.

d.healey

I've solved half the problem with my recent velocity range of 1 modification. So now each sample is mapped to the correct MIDI note, as shown in the below image. But I still need control over the velocity because I have each velocity layer separated.

I'm not finding any way I can get the velocity gain modulator to respond to the incoming MIDI velocity if I set the artificial note's velocity.

This snippet is a simple strum script. When you press a key a timer will play through each note in an array, each at a fixed velocity of 60. If I enable to velocity modulator in the gain section I just get silence. I need it to be fixed at the velocity of the note that triggered the on note callback, how can I achieve this?

@d-healey I just tried moving your script in the interface proc and it seems to work so you might want to check that.

d.healey

@ustk hmm I will investigate

d.healey

@ustk It doesn't seem to work for me, the only difference is the velocity mod is now fixed at 60. What result do you get?

d.healey

Ok I just tested this in Kontakt and the behaviour is the same - how did I not know this!

The standard solution would be to use the change volume function on each note based on the real velocity. But I'm wondering if I can find a solution using a scripted voice start modulator.

ustk

@d-healey Like this, the velocity is the one you set in the script.
What if you do that:

I'm sure you already know the "how to", so I imagine you have something in mind preventing you from using getVelocity()...

ustk

@d-healey I don't know how to use the scripted modulators, would be cool...

d.healey

@ustk

so I imagine you have something in mind preventing you from using getVelocity()...

Yeah this is the problem. I need to be able to specify the velocity. Have a look at my screenshots above, I have mapped each string, rr, and up/down of the guitar to a different velocity.

The other solution is to use individual groups but then each articulations (assuming 3 dynamics) will need 24 groups, and if I have 10 articulations that's a lot of groups to manage. And I can do it with 1 group per articulation with the velocity method.

I'm going to play around with the script modulator and if that doesn't work I'll just use a addVolumeFade command.

d.healey

I think I've done it :)

I capture the real velocity in a global variable and then I pick it up in a script modulator to apply the gain change.

@d-healey Glad you found a solution mate ;)
So if I understand well this function returns the Gain (0-1 based) because the Voice Start Mod is in the Gain modulation...

function onVoiceStart(voiceIndex)
{
	return g_velocity / 127.0;}

d.healey

Yup - https://docs.hise.audio/hise-modules/modulators/voice-start-modulators/list/scriptvoicestartmodulator.html

ustk

Thought there was nothing in the doc yet... Wrong me...

d.healey

I think it's probably better to use a midiList and record the velocity for each individual note, although this might be overkill

return g_velocity.getValue(Message.getNoteNumber()) / 127.0;

Although this won't work if you're offsetting note positions.
