Re: Visually grouping AU parameters in generic view



You guys need to make use of the clump feature to group your audio unit parameters. Use kAudioUnitProperty_ParameterClumpName to specify the clump name, and AUBase::HasClump (outParameterInfo, theClumpID); in GetParameterInfo() to specify which clump a given parameter should be placed in.

If you search the list for "clump" you should find additional information on this topic.

Hope this helps!

Hi,

I'd like very much to know how to do that too for a generic Cocoa view: displaying a group of parameters inside a NSBox (optionally titled) like in Apple's "AUMerger" or several groups inside a multi-box view like in "AUFilter".
Displayed as a little blank separator in the generic Carbon views, this feature could offer a nice layout quickly made in Xcode with no custom GUI.

Warmest regards,

Hello everyone,

Over the past weeks and with many thanks to Michael Hopkins I've been able to implement a lot of nice features in my new Audio Unit.

Right now, I'm wondering if it's possible to visually group parameters like in AUFilter (with captions) or AUMerger (without captions) using the generic view. I know I'm pushing the limits of these generic views, but I'm a bit reluctant to creating and maintaining a custom GUI, because it brings a lot of extra work with it.

I have tried several kAudioUnitParameterFlag values, like _Group (which seemed obvious) and _HasClump, but I can't seem to find documentation on this topic and they don't work automatically. I've tried Google with several parameter names, but I don't get any descriptive results or useful sample code.

Can anyone enlighten me if these kind of tricks are possible and how to accomplish them? Thanks in advance for your replies.

With kind regards,

Frank Schoep
