How to prove that, i have buying a licensed??

everyone have any ideas? is there any article for reference?

so exhausted......

I don't know how...so now i am trying....

huen97

I want to create a button , separately for 1-6 EQ...

huen97

@d-healey why this example not working for me , I am trying to use the button to load the presets , but fail.....

huen97

What should I do if I want the combobox to load only a few presets, currently I have created two Samplers, I want this combobox to only load the presets of sampler2

Sorry my bad English
