OSC mapping seems raw

Hello.

I'm using the IRCAM ToscA plugin to send OSC from Pro Tools to Kyma. Setup was super easy.

However when I 'learn' a controller on the VCS the value is only ever set between 0-1 (the values that I'm sending). It does not get scaled to the range of the control on the VCS.

The OSC log confirms that I'm only sending values between 0-1.

Is there a setting that I've switched by accident? Do I need to format the message in a certain way to get Kyma to do the scaling?

Thanks, Andreas

I've switched to using OSCar instead of ToscA

This is the messages I'm sending from OSCar:

'/1/param1' gets mapped correctly to the ranges on the VCS no matter what the ranges are.

BUT '/1/param2' does not - that message sets the VCS value "raw" and does not map to the range of the control.

What am I doing wrong?

Are both parameters faders in the VCS? In other words, is either of them a SoundToGlobalControl Value or GeneratedEvent?
I'm just using 'Freq/Time Scaling Vocoder' for 'An Overview.kym' - so no.
Which parameter has the seemingly raw range? Is it !Frequency? (Seems like that is the only non-[0,1] fader in the VCS...)
That's the weird bit:
My first osc message; /1/param1 will map perfectly to any control regardless of its range so I can map it to frequency AND bandwidth at the same time and the two faders will move in tandem but each respecting their range.
No matter what I assign /1/param1 to the range is always considered.

However anything I assign /1/param2 to is set in this 'raw' way. Always between 0-1 regardless of the range and which VCS control it's assigned to.
This is also the case for any other osc message /1/param3...32
Experimenting a bit more I found this:

It doesn't matter what the osc message is called.
If I reset the OSC map using the helper tool then;
the FIRST osc message will always map correctly in the VCS.

Subsequent osc messages will map in this 'raw' way.

Even if the range on the first mapped VCS is 0-1, the same osc message will map correctly onto other ranges. But ONLY the first received osc message will do this. (the rest only sets values between 0-1)

Does that help?

Andreas, have you tried to send from Tosca or OSCar the message in the format

'/vcs/param1/1'

'vcs/param2/1'

so they are immediately recognized by the VCS without need to mapping?
