Variables for Automation

Postby SBMastering » Fri Jan 25, 2013 9:55 am

I'm working on a VST idea that is nearly complete. A weird problem has come up.

The user needs to be able to use automation in the DAW for the VST idea to work correctly. The DAW (Samplitude) doesn't show any automatable variables for the plugin.

Does anyone know how you can make a variable in your VST be seen by the DAW, so that it can be automated by the DAW? I have a slider that I want to be able to be automated in the DAW.

I have other VSTs I've made where the variables are listed and automatable by the DAW. I didn't do anything special that I remember to get that to happen. I'm not sure why it's not happening with my newest VST.

The "Auto" input on the (VST) PresetParameter primitive has to be set on true. I guess you have one included at the parameter you want to use inside the VST?
But there were some randomn bugs with some hosts. One can be found here:

EDIT: Ah and i forgot the most important ;). Of course you have to include a Preset Manager in your VST!!

Ohhh....That reminds me to ask for a bugfix...thanks... ;)
So maybe someone who's reading it and owns Cubase can test it?
EDIT: I tested it myself just to find out that the bug still persists... :x

Plus - for automation - all values stored in presets must be in (0-1) range if your create your own modules. Values don't need to be scaled that way if you don't use automation in DAW, just rendering.
Need to take a break? I have something right for you.
Feel free to donate. Thank you for your contribution.
