A few questions relating to synthesis

Christoph Hart

Hi Trivalve,

yeah, the HISE Player never made it past the prototyping stage, mostly because of lack of interest compared to the other distributing options in HISE. That might change in the future, but I'll take it off the website with the next redesign.

About your questions:

The harmonic filter is a polyphonic filterbank with multiple peak EQs that are automatically set to the root note and it's harmonics. You can use up to 16 filters, define 2 "harmonic spectrums" (which are just gain values) and crossfade between them. It's a rather CPU intensive module, because it's a lot of number crunching, but if you keep the amount of bands to the minimum of your requirements, it can yield some interesting effects.

Where do you get that impression? You can't actually hear phase correlation between harmonics

@christoph-hart After some research and asking around, it seems especially important for, say, instruments like strings - I've been told modulating the phase of the harmonics is one way to achieve the correct sound. But I have no way to control the phase in HISE (yet).

@trivalve @d-healey a bit off topic but I remember you David to do a test with a lot of sine wave generators for partials. The question is: is it possible to do partials via scripting? Like:

Sine_generator1{
gain:1;
adsr:0,30,0,2;
Lowpass-freq: 30;
lowpas-adsr: 7,80,28,2
Etc};

Sine_generator2{
gain:1;
adsr:0,30,0,2;
Lowpass-freq: 30;
lowpas-adsr: 7,80,28,2
Etc};

Sorry this is the way I found to explain it.

d.healey

@hisefilo You're better off using CSound (or Cabbage) which has oscillator banks designed for this kind of thing.

hisefilo

@d-healey the thing is Csound and Cabbage lacks for an awesome UI creator like Hise's. And both require to embed Csound source in order to deliver a functional plug-in

Christoph Hart

If you're talking about phase modulation, you can slightly modulate the pitch which is the same thing.

I was refering to a static phase correlation between harmonics, which can't be heard by humans.

@christoph-hart Oh, I should've thought of pitch modulation. Duh. By the way, was the wavetable synth ever updated? I remember you were working on a tool to help turn crescendo samples and such into wavetables. I find myself needing access to such things the more research I do. On a side note, is it possible to perform pitch bends interpolating between all the pitches represented by a wavetable?
@hisefilo I think the hnode thing that Christoph was working on might be what you're looking for, but it's not out yet. I'm also highly interested in that for my purposes (imitating acoustic instruments via synthesis).

hisefilo

@trivalve Yes, that's right! I'm also playing with synthesis for imitating real instruments, this is my attempt for a Wurlitzer ~~(sorry cant find the way to embed snippets properly)~~ figured out. 4 spaces before code :)

@hisefilo 4 spaces? I tried it didn't work for me

@jay Christophs also worked. I think I googled and found the 4 spaces sintax for code blocks somewhere

hisefilo

@Jay
To produce a code block in Markdown, simply indent every line of the block by at least 4 spaces or 1 tab. For example, given this input:

This is a normal paragraph:

This is a code block.

Markdown will generate:

<p>This is a normal paragraph:</p>

<pre><code>This is a code block.

@trivalve Did you get something working on additive synthesis within Hise? I'm in the same path with some good results. Main issue for me is to control 25 partial's envelopes depending on velocity an key number. Any advice? I'll be happy to share with you what I've learned

NotHereAnymore

@hisefilo Not yet, mostly still experimenting and doing research. That's also a problem I've been thinking about.

hisefilo

@trivalve Oh. well, maybe this inspires you to start trying. 12 partials EP not the best but getting there https://soundcloud.com/user-830166644/additive-test
