@d-healey yeah that'd work - I guess I will leave my script envelope experiments for another day .... thanks.

@griffinboy said in Drift.... and how to design it....:

@Lindon

I went over the top and fully modelled VCO drift a while ago including the interactions between voices.

You can collect pitch draft data from synths by holding a seriously long note, and then running the file through praat and creating a csv of pitch values. Then use python scripts to organize and clean it up.
You can then use Matlab or python to analyze the data and figure out how to get a match.

... Or just use the values as a LUT
Real analog oscillators have a kind of vibrato as well as slow drift. And they also have moments where they quite suddenly bend out of tune.

Well thats very clever, but first I'd like to get this simple case working.

@d-healey I want a fixed random value for each note....

on my machine moving the intensity slider as you point out shifts the entire note - set it on 12 and it is always 12 semi-tones away from the played note - not some random value between 0 and 12...

so this is as far as I have got, so Im generating a random number - but Im not even sure it's being applied to the pitch of the note, or how to set the depth.....

@Orvillain well thanks for that - but Im not thinking about polyphonic LFOs _ I dont want an LFO - I want a random pitch offset value for every note played...

@Christoph-Hart - well clearly I have no idea what Im doing here...

@Christoph-Hart ok thanks I will give this a go...

OK so I have a number of synth based voices and - in classic old-style VA synthesis I would like the oscillators to drift slightly in and out of tune.

I've been doing this for a while with a random LFO in the Pitch modulation slot.... but of course this is "monophonic" i.e. every note is drifting by the same amount, and now I'd like to drift each note independently from its peers.

Envelopes are "polyphonic" in nature, so I assume(probably wrongly) I need some sort of envelope in the pitch modulation chain, that varies the played note by some small amount randomly...

A Script Envelope Modulator looks like a possible candidate, but I've never needed to use them and have very little idea where to start... I've fiddled for a morning and Im getting nowhere... any clues on where to start, or another way to achieve this outcome?

..0h forgot to mention: yes clearly I could do this in a std script processor with addPitchFade - but looking to not add more complexity to my HUGE script processor chain...

@gxxdstress so first dont put spaces in your project names - use CamelCase, second its missing xcpretty - so download and install that.

Did you build HISE from the source?

@Christoph-Hart thanks _ I'll give it a go...

@Christoph-Hart tomorrow?

@Orvillain There are several post (quite old now I think) about this "problem" - some may have even been from me. In the end modulating a filter freq this way turned out to be not the best way to do it... add this to your settings - and to your HISE compile:

NUM_HARDCODED_FX_MODS = xxx

and you can add modulation slots to your hard coded FX like this:

I have mine set to 3 so I get 3 modulation slots - that can hold most types of modulators - and they apply to the first 3 params of my hardcoded fx....

@Orvillain use the pma modules?

@Oriah-Beats try studying some of the example snex shaper files...- I know a few have been posted

taking the code youve written for the shaper and applying in a clean project results in a parsing error - so your code isnt right either..

I think probably because you named your scriptNode network snex_shaper - which is the name of a node - so dont do that for a start.

@Oriah-Beats well it fails to compile with these errors:

@Oriah-Beats theres an even better drag-to-resize option that Christoph posted a while back - search the forum.

@Oriah-Beats post a snippet

@Oriah-Beats it seems to think you do....container.oversample2x - maybe thats your problem...

do you have any other scriptnode networks in the project?
