all keys sense impact velocity as well as continuous pressure; most have
location as well; each can be assigned an arbitrary static output voltage -
in total, far too many input parameters to be independently routed to
outputs.

instead there is a reasonably large space of outputs that can be mapped to
inputs more or less at the user's discretion.

keys can be divided into potentially overlapping "groups" of up to 25 keys.
each group can have a custom routing of parameters (pulse, impact, pressure,
location, and fixed assignable per-key voltages) to output jacks (4 per
group.)

there are 4 groups with 4 outputs each; another 5 groups have only a single
pulse output each, another 5 groups have only a single voltage output each.

there are some interesting options for polyphony and stealing, as partially
implied by the term "radio group."

the "R" and "S" keys are two-dimensional location pads with hardwired X/Y
outputs. there are similar hardwired outputs for the infrared ring
locations.

that's it!

yes, but it does not have a preamp, nor any kind of level control, and so
its behavior is rather more circumscribed.
