Here's the PR with the preprocessors. I already closed it but leaving it rather than deleting in case the specifics help anyone.

https://github.com/christophhart/HISE/pull/995

The two preprocessors:

HISE_MIDI_AUTOMATION_IN_USER_PRESETS // load/save CC mappings from preset data? HISE_MIDI_AUTOMATION_IN_PLUGIN_STATE // load/save CC mappings from session data?

Allow you to set up any of four scenarios:

U=1, P=1 (default): "I want CC mappings to be part of the sound, recalled with every preset, and I also want each plugin instance to remember them in the DAW session."

U=0, P=1 (per-instance): "I don't want browsing presets to touch the user's CC mappings, but I do want each instance to remember its own mappings when the DAW session reopens."

U=0, P=0 (global, script-owned): "I don't want presets or DAW sessions storing CC mappings at all, because I want one global mapping file that my script owns and every instance shares."

U=1, P=0 (odd but technically legal): "I want CC mappings treated purely as patch data that loads with each preset, but I don't want sessions keeping their own separate copy that could drift from whatever preset is loaded."

I'm going for the per-instance approach plus manual [Save As Default Map] and [Load Default Map] buttons in my UI.

Feels like the best approach for my synth, and what I would want as a user.

Each heavyweight function (loading presets, samples, etc) gracefully fades out the audio, suspends the processing and then resumes audio processing. This is a core engine behaviour and you can't do anything about it. Changing this will create audio glitches, incontinuities and crashes.

@observantsound Confirmed here on Linux

@Chazrox Amazing! Thank you for your hard work and for sharing it with us!

@ustk take my money! 😆

@ustk Thank you so much,

This it it.

UPDATE: Auto-Detect + Dynamic GUI Sizing

When you download the HISE package, you will not be required to enter the GUI size anymore as it is auto-detected directly in your project. Thanks @David-Healey

Also, the complete HISE package is dynamic and will change dimension based on changing GUI elements (like an expandable keyboard or effect section). Thanks @dannytaurus

For example: Customer didn't pay for their subscription, grace period ends, they are using plugin now with the keyboard extended. The plugin will pause, popup the activation webview, and the webview overlay will still block the entire plugin, not just the original size.

@manued12 said in Looking for HISE help – Simple Sample Mapping + Looping:

Files are already correctly named and prepared

If they are named well all of the steps except the looping can be done in about 30 seconds using the token parser.

So you're basically paying someone to loop your samples - I would suggest looking into auto loopers like LoopAuditioneer first - because anyone taking the gig is going to be doing that ;)

@Sifres @dannytaurus I've started to add this because its already a popular method to use a slider to make peak meters. Coming soon! 👍

@BWSounds In that case try a different xcode version, one up or down from your current one - not sure which I'm using, it's been a while.

Also only use the JUCE6 branch, JUCE8 is currently broken.

@GUJIAN No, but you seems to be trying to use Rhapsodist in the second image and the template in the first image.

Thank you! That all makes sense

@griffinboy

I realized that these plots are a little misleading.

The VCS3 filter is highly nonlinear and "bubbles" and so taking a measurement of frequency response is quite difficult since the filter is moving around on it's own accord all the time...!

Here is a more detailed FFT that shows how the filters do match more closely than the graphics in my paper would suggest.

.

Black is the slow accurate VCS3, Red is my optimized VCS3.
Not oversampled.

When oversampled, I found the proposed model to be perceptually close to the slower accurate model. The resonance and cutoff and gain values differ slightly, but the important aspects of the filter are retained.

Update!

Dual SVG capabilities for buttons such as this.
(shown compiled in HISE)

Both import methods and settings panels are identical but are independent from each other between button states.

And If you didnt already know...
You can also do some pretty nice LED's with the app as well! 👍

They're available now in the preset menu.

@ustk I'm indeed still on the latest stable release...
I read it as 4.10 instead of 4.1 so I was convinced I was on the latest version.
I'll compile from the latest develop branch instead and try again.

So what state is the mod matrix actually in?
Do some things work but others don't?
I'd just like to know what to look out for, if the documentation isn't super up to date.

What are PRs?

@dannytaurus That is a massive, massive bummer. I hadn't seen that. Guess I'm going down a rabbit hole trying to get the graphics portions working again, I 'just' need GLSL shaders working again, it worked fine in an older build of HISE so hopefully not too much to work out.

@lalalandsynth

Ah that makes sense,
yes indeed that was the only thing.

In that case, great work all round.
I'll keep you in mind for some upcoming projects.

@duma Try a different xcode version

@ustk Until July 7th anyway. Then I'll probably only use it for big tasks! 💰
