@David-Healey I've fixed it - just incase anyone ever sees similar weirdness in future -

Open Terminal and:

xcode-select -p

That should return similar to:

/Applications/Xcode.app/Contents/Developer

If not, sort it with this:

sudo xcode-select --switch /Applications/Xcode.app sudo xcodebuild -runFirstLaunch

Then reset dev tools:

sudo xcode-select --reset sudo xcodebuild -license accept

Delete derived data and module cache:

rm -rf ~/Library/Developer/Xcode/DerivedData rm -rf ~/Library/Developer/Xcode/ModuleCache.noindex

Double check clang if you've got clang errors:

clang --version xcrun clang --version

If either of those hang, reinstall clang.

Reinstall commandlinetools:

sudo rm -rf /Library/Developer/CommandLineTools xcode-select --install

Delete Xcode caches (bit severe but I think this is what sorted mine out):

rm -rf ~/Library/Caches/com.apple.dt.Xcode rm -rf ~/Library/Preferences/com.apple.dt.Xcode.plist

Then reboot, open HISE and try your compile again - mine went straight through, no errors!

@David-Healey Thank you so much

@dannytaurus Thank you so much, I went for the easy method.

@PabloCaparros

Sounds like a plan!
If time is on your side then start with Hise.
Especially if you're new to making audio software, it'll be more satisfying to start with Hise (which has a gui and built in tools) and because of the great forum - use it if you get stuck!

Good luck 🫡

@mysticsh

If you could describe exactly the situation / problem,
I can give some advice!

I don't fully understand what you're after!

@Lindon Yep - totally get what you're saying!

I don't want the user to see the combobox it's just to have presets stored correctly

@Christoph-Hart said in Sampler: Preload Size question:

You probably might want to put that in a non-preset setting file somewhere.

exactly what im doing....

with the complication that the Preload size is actually being set in another executable, the "player", so now when the Full instrument Expansion gets loaded I say this in the init:

for(i = 0; i < NUM_SAMPLERS; i++) { if((instrumentMetadata.instrumentSettings.PreloadBuffer * 1024) != TheSamplers[i].getAttribute(TheSamplers[i].PreloadSize)) { TheSamplers[i].setAttribute(TheSamplers[i].PreloadSize, instrumentMetadata.instrumentSettings.PreloadBuffer * 1024); } }

only question is -- do I need to wait for everything to load before checking this?

@David-Healey Ah very nice, thank you! I will give that a try!

@David-Healey thanks yeah spent another go round in the source to uncover this too.. thank you.

@Christoph-Hart said in Filter gain modulation not working correctly:

If you then want a modulation to go from -6db to +6dB, you just leave the knob position at 0dB and add a bipolar modulator with +6dB intensity.

Little bump and also, would this work for nonsymmetric ranges? I ran into one today where I'd like to go from -12db to +3db.

Also there is still this bug with artefacts and voices overwriting each other:

@pelle I think you can use ilok cloud, I'm not sure a physical one is required, I could be wrong though.

It's free to sign aax plugins but you will need a signing certificate for each OS.

If interested, I have made some workshops that cover the signing process (they don't cover setting up the SDK). https://audiodevschool.com/course-bundle/packaging-workshop-bundle/

@Christoph-Hart said in Best practice for Real-Time Metering: How to pass dynamic peak values from RNBO to HISE UI?:

ah here you hit a real limitation - multiple modulation outputs are not supported for RNBO at the moment.

According to your screenshot the second one is just a peak hold - if you replicate this in scriptnode you should be able to get by with a single output.

Ah, ok, yes that´s a good idea, thanx

@duma It will appear near the top of the list - not in alphabetical order.

These are custom fonts I've loaded (below Source Code Pro)

@David-Healey Well, then it gets way more tedious to adjust the position of each element. But fair, that's probably the easiest solution. Thanks :)

@boim98208 @Christoph-Hart Do Flex AHDSR Envelopes require connecting to a floating tile? The issue I have of Flex AHDSR not triggering the samplers was also an issue when I did a compiled build

@David-Healey also don't forget the buddy of HISE_MACROS_ARE_PLUGIN_PARAMETERS:

HISE_NUM_MACROS. Help text in the upcoming docs:

HISE_MACROS_ARE_PLUGIN_PARAMETERS

Publishes every macro control as a dedicated plugin parameter in front of the scripted automation slots.

Default Hot Reload Auto Config 0 yes no

When enabled, the exported plugin advertises one plugin parameter per active macro slot before any custom automation slot or scripted plugin parameter, which lets the host automate macros directly instead of routing through a UI component. The plugin parameter index reported to the host changes because the macro slots occupy the first positions, and macro state no longer restores from user presets when the preset system is running in exclusive mode (which matches how plugin parameters are normally managed by the DAW rather than by the preset). Combine this with a reduced macro count to keep the parameter list compact.

Read at runtime from the Extra Definitions, so no HISE rebuild is required. Pair it with HISE_NUM_MACROS so the number of exposed plugin parameters matches the macros you actually use.

See also: $API.MacroHandler$ -- macro slots exposed as plugin parameters are the ones managed through this scripting object, $MODULES.MacroModulationSource$ -- every macro slot is mirrored as a front-of-list plugin parameter when this is on, $PP.HISE_NUM_MACROS$ -- determines how many macro plugin parameters the host sees

HISE_NUM_MACROS

Number of active macro control slots that the project exposes on the master chain.

Default Hot Reload Auto Config 8 yes no

Sets how many macro slots are visible to scripts, to the macro handler, to the Macro Modulation Source synthesiser and to the macro plugin-parameter publishing path. The default of 8 matches the original HISE layout and the UI panels that show a fixed eight-knob strip; values between 1 and the project-wide ceiling let you trim a compact product or scale up to a modular rig with many assignment targets. The value is read at runtime, so changing it in the Extra Definitions and reopening the project is enough to see the new slot count without a HISE rebuild.

Must not exceed the project-wide macro ceiling of 64, otherwise compilation fails with a hard error.

See also: $API.MacroHandler$ -- slot count seen by every scripting call that enumerates macros, $API.Engine.setFrontendMacros$ -- setFrontendMacros expects a name list sized to this value, $MODULES.MacroModulationSource$ -- chain count of the macro modulation source synthesiser matches this value, $MODULES.MacroModulator$ -- macro modulator slot index is validated against this value, $PP.HISE_NUM_MAX_MACROS$ -- hard upper ceiling that this value must not exceed, $PP.HISE_MACROS_ARE_PLUGIN_PARAMETERS$ -- determines how many plugin parameters are published when macros become plugin parameters
