Hi Mike,
you're doing it the right way. That you don't see the name in Logic is a Logic thing. Just copy the parameter name also to the AudioUnitParameterInfo name field and Logic will show it. Seems like Logic don't know anything about CFStrings in this context.

Hi Bill,

thanks, I read and tried that. Doesn't work for me. Can somebody post a
short example?

This is my version:
------------------------------------------------------
In "GetParameterInfo"

sInfo.cfNameString = CFStringCreateWithCString(NULL, sInfo.name,
kCFStringEncodingISOLatin1);
sInfo.unit = kAudioUnitParameterUnit_Generic;
sInfo.minValue = 0.0f;
sInfo.maxValue = 1.0f;
sInfo.defaultValue = 0.0f;
sInfo.flags = kAudioUnitParameterFlag_IsReadable |
kAudioUnitParameterFlag_IsWritable |
kAudioUnitParameterFlag_IsHighResolution |
kAudioUnitParameterFlag_HasCFNameString |
kAudioUnitParameterFlag_ValuesHaveStrings;
------------------------------------------------------

Now, *HOW* does the host try to retrieve the string for the current
value? In "GetProperty"? Example please....

Do I need to do something in "GetPropertyInfo" do the host knows it
makes sense to call GetProperty at the time the value changes? What
*exaclty* (example)?

Regards,
Mike

Have a look in the latest SDK - there's docs and API there to allow
you to translate between parameter values and the strings that should
be used to display them (and to convert back from a display string to
a value as well)

Hi all,

how can I use custom parameter value strings like the VST-method
"getParameterDisplay()"? What I basicly want is that the host calls
my AU and asks for a string to be displayed for the current value
(e.g. during automation).

Thanks in advance for any help you can provide.

Cheers,
Mike
