Max<>Paca OSC value ranges

Question

Hi all,

I have been experimenting with OSC udp communication between Max and my Paca.
I manage to get Max floats to the VCS and a response back.

What I would like to know is whether the floats coming back from the Paca are always the fader position scaled between 0. and 1., or is there a way to send floats from the Paca that are not scaled between 0. and 1.?

The solution I can see now is using the "minimum" and "maximum" values from the VCS Widget Description, send by the Paca in response to the "/osc/widget,i" request, to scale the 0.-1. range back to the VCS value in Max. But that would involve quite some initialisation communication.

Many thanks,
David

Hi David,

Yes, the input and output range for OSC values is [0,1].

You can use the VCS min/max/grid settings to scale those values inside Kyma. But what you send and receive is always in the range of [0,1].

To send & receive values outside that range, you can use the new(ish)

/osc/receive_raw, i

where i = 1 sets RAW mode and i = 0 toggles out of the RAW mode.

In RAW mode, you can send and receive arbitrary values, outside the range of [0,1].

Thanks! the "/osc/receive_raw 1" did the trick.

Now I'm struggling with the VCS faders only sending a value on mouse up and the moving SoundToGlobal Parameter OSC fader freezing when I move another fader.

Are there workarounds for those behaviors?

All the best,

David

If you position the cursor over a fader and scroll (without a mouse-down) then the faders are continuously updating.
Also, if you use an external controller (like Kyma Control on the iPad), the fader values update more often.
