@boim98208 I think it can be done with the event programming. So that when you note on, you ignore that note, and create instead your own artificial note event but you add some fine tune pitch to the note message.

@Jeetender

Right but the math works the same way.
All you need to do is find the right hise functions in the API for the math calls.

@dannytaurus

Haha, we aren't there yet.
AI is a fool when it comes to Analog Modelling.

But maybe someday.

@Jeetender

This is pseudo code.
It's something like this

// Equal-power wet/dry crossfade (pseudocode)

// knob range
value = 0 to 127

// normalize
t = value / 127.0


// equal-power law
// sin/cos keep total power constant
wet_lin = sin(t * PI * 0.5)
dry_lin = cos(t * PI * 0.5)


// linear → dB
// dB = 20 * log10(gain)
// log10(x) = ln(x) / ln(10)

wet_db = 20 * ln(wet_lin) / ln(10)
dry_db = 20 * ln(dry_lin) / ln(10)


// clamp near zero (avoid -inf)
if (wet_lin < 0.00001) wet_db = -100
if (dry_lin < 0.00001) dry_db = -100


// apply
WET.Gain = wet_db
DRY.Gain = dry_db



/*
Behaviour:

t=0
dry=1.0  (0 dB)
wet=0.0  (-inf)

t=0.5
dry≈0.707 (-3 dB)
wet≈0.707 (-3 dB)

Summed signal power stays constant across the crossfade,
so the centre position does not sound quieter.

This is the kind of question that AI can help you understand.
Ask chat gpt about it until you get why it works!

@Jeetender

Wet / Dry balance is done using a sin / cosine curve usually.
You don't need to do any RMS calculations for an equal power curve.

@DanH
Not supported.
I'm assuming at this point it must be troublesome to add scroll wheel detection, because it's been requested over the years multiple times.

@Alatar said in Audio Engine Sample Rate?:

Is HISE using an internal sample rate, which is different from the host sample rate?

Hise plugins run at the DAW sample rate.

The Hise app itself runs at the sample rate you choose in the settings.

Resampling may occur somewhere else on your PC, but Hise is trying to match whatever it's told.

@Alatar

The sample rate conversion is immediate. It happens during runtime.
The rate at which the sample is played back (in other words the pitch) takes project vs file sample rate into consideration.

The sampler plays back the file at the right speed for whatever sample rate the Daw reports to the plugin.

After all, a sampler that plays back sounds at a different pitch is a resampler by definition. So all the work can be done at the lowest level in the sampler, outputting the samples at the correct sample rate (speed) to begin with.

@dannytaurus

yeah this is what shows when there is an error, it stops at this point and prompts the user to close the window, without the Completed message.
What's odd is that there is no error message above.

There definitely is some kind of error here. Its refusing to compile.

@griffinboy

Solved, it was me being silly. I checked and it was only certain projects that had the issue.
After investigation I found what I had done wrong:

#include <Windows.h>

^ I had used this line in my c++ nodes,
And it happens that Windows.h has methods with the same naming as some of the Hise files, creating a conflict.

The include was actually in a dsp file that I wasn't even using, which is how I missed it.
But when Hise goes to compile as VST it runs every c++ dsp file, and so the error flagged.

Latest Hise Build, Juce 6.
I am unable to export to VST3 on Windows.

Is this a bug, or something I've not set up correctly on my end?

@HISEnberg

Indeed!
I've also got someone after this. But judging from the lack of movement on this, my guess is that it's troublesome to implement

I do custom dsp for Hise.
Analog modelling, circuit similation, synthesis engines. Adapted from latest research.
The scientific side is my specialty.

@dannytaurus

Looks fine! Especially for something like an LFO selection.

See how tiny the Ableton dropdown selection boxes and multiple choice buttons are in the background?

@Lindon

Ah!
How bizzare.
Yes now I remember, Asio doesn't like multiple different apps trying to leach audio. I remember now, I switched ages ago to a different driver because of this. It pained me to do so.

@Lindon

The OBS beta capture does work with Hise on my machine.
I'm on Windows. I'm sure it works differently for each OS.

It's very picky about capturing audio from exact window names, unless you set up the following option. So if you're getting silence it could be because of this. But I assume you've already tried fiddling with all the available options by this point, so that's probably not useful advice.

Does the regular system wide capture not work?

@Phelan-Kane
@Lindon

I use virtual cable on windows for any custom routing.

And I alternate between using OBS system wide audio capture, and the experimental app audio capture feature, depending on my needs at the exact moment

If you want to record high quality audio without alias / resampling issues please record to mkv in flac format. Default OBS has audio artefacts that are audible.

@Phelan-Kane
I've yet to use the matrix modulator with any filters, I think this is an issue for @Christoph-Hart to have a glance over!

That being said, any dsp I've posted on the forum is long overdue an update, most of those posts were incomplete dsp, given out as a starting point, with the intention that it would be modified. Robustness is one of the things that was not fully fleshed out.
Although, if even the default hise filters are failing, I doubt it's an issue to do with that, since all the default Hise filters are simple designs chosen to be modulation safe.
