Dear gang,

Here's the reply I got from Mr. Doepfer RE what the features will be
(so far) on the sensor keyboard. Realize that this is still in the
planning stage, so we really need to let them know that we want this
one to be built!

Here is the current state (so far only in our heads, we only designed
the touch
electronics so far) of our sensor keyboard discussions (so far only
one
rotary
control per key are planned):
about 2-3 octaves (i.e. about 25-37 keys)
first LED for each key (to show the state of the key on/off)
gate output socket for each key (outputs the LED state as a gate
signal)
second LED for sequencer step display
control (rotary potentiometer) for each key
CV output for each key (position of control knob defines voltage, a
kind of
25-fold CV source)
general features/outputs:
CV out 1 (quantized output that corresponds to the key like a
standard
keyboard,
1/12V resolution per tone)
CV out 2 (this outputs the control voltage of the active key that is
adjustes
with the potentiometer controls)
CV out 3 (after touch voltage, derived from the pressure sensor below
the
keyboard)
Gate out
MIDI out (by the way the MIDI out would not increase the price very
much so that
we will add this in any case)
In "keyboard mode" the outputs are used as described above. CV1 is
the
normal CV
output. CV2 can be used to create arbitrary scales of completely
random
CV
voltages assigned to the keys.
In "analog sequencer mode" CV2 and Gate work like the output of a
analog
sequencer. The keys can be used in this mode for different settings:
e.g. to
turn on/off single steps - or - to define the first/last step of the
sequence -
or- to define which steps of the sequence are played (only those
steps
are
active where the keys are touched, the remaining steps may be skipped
or played
with a pause).
In "digital sequencer mode" a sequence can be recorded into the
memory
by
playing the keys. In play mode both CV1 and CV2 can be used
(remember:
CV1 is
the "normal", CV2 the "free scale").
For the sequencer sync to (hardware) clock or MIDI clock is possible.
Unfortunately most of these features would be possible only
monophonic.
This is
why I would tend to a monophonic keyboard. But in the normal
"keyboard
mode" 4
voice polyphonic should be no problem.
