200e

Hi everybody.

I want to ask you some clarifications on how the 222e interface works in relation to the touch surface: why are there 27 keys and 30 outputs, which are grouped in different types? and what labels like "radio out", "R and S", "location/pressure/impact" exactly mean?

next, I'd like to have some comments on 297's envelope follower: is it suitable to create amplitude-dipendent effects like the 227e's one?
Because in my ideal system (accomodated in a 12WLS cabinet) I would use a 206e instead of 227e as a mixer, but I'd like still to have a env follower.

thanks a lot :)
Francesco

thanks a lot, ezra, very exhaustive

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.

i think i made a couple mistakes there. like not all keys are
pressure-sensitive (the toggle keys are excluded, as in the Thunder.)

and i realized maybe a couple examples are in order:

1) you can take a range of keys and assign arbitrary output voltages to each
one, all of which come out of a single jack (a "keyboard.")

2) among those keys you could have the last one you touched always send its
location out of another jack (each key in the "keyboard" operates the same
"fader.")

3) you could make the pressure of each key, or arbitrary subgroup of keys,
go to a totally different parameter via a different jack (up to 9
independently.)

4) on top of the universal fader assignment, you could have 3 more fader
outputs that are simultaneously operated by 3 subgroups of the main group of
keys, which subgroups need not be mutually exclusive, nor exclusive with the
subgroups of 4).

5) you could have a single key in any of these groups trigger a single
pulse, or toggle it.

6) you could do 1)-5) at the same time.
