All of the strips send CV in a stepped fashion, no matter which factory preset is loaded.
Of course this behaviour makes sense when using arches as a musical keyboard, but in order to use CV for parameter control, it needs to send smooth changes in voltage as you move your finger up and down the strip.
Is this going to be implemented?
The LS-1 behaves in the same way, but feels like its resolution is higher, i.e. smaller steps, and thus more acceptable when controlling e.g. filter cutoff frequency.
