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)
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].
