a glaring omission i for got to include to the post below is
portamento with a voltage control input.

plus have a look the 221 photo in the buchla folder in the files
section. above the keys, there are a row of smaller touch squares. it
would good to have a pot then three these squares on the left side
then two longer squares of the same height modeled after the 217
touch plates in the middle to react to position much like a ribbon
controller and then three more little squares and a pot. why the 3
squares and a pot the left 3squares and pot could be used for
pitchbend. the pot controls the time for the pitchbend to reach its
final voltage from 0ms to 10sec.now if you use a pull style pot, you
could then adjust the level output voltage from 0 volts to 5 or 10
volts. when you touch the left square it ramps downwards to the
voltage and time set by the pot and maintains that voltage until you
let go of the square touch plate. if you wish to glide back up to 0
volts from the top you hold the right square down and touch the
middle square of the 3 until you reach o volts. same goes for the
square to the right of the middle square, except it ramps upwards to
voltages set by the pot. kind of like the Arp Oddessey pitchbend pads
but with added control by the pot. you could two pots if a 2-way push
pull pot is not good in case of durability.

it would be great if this were available polyphonically to each voice.
sorry, it has to be available to the polyphnic outputs.

now you mirror the same on the other side of two long position square
touch plates. the right side could used to bend the filter cut-off or
any other voltage control input. this one is not attached to the
keyboards cv/gate outputs you can use independently to any input.

don't mention it, this is the straight-up bomb. boy, i would pay an
extra 200euros to have this feature implemented. this feature added
the unit would cause quite a stir. it would be more like i have to
have this unit than maybe i'll think about it. why because it does
not exist anywhere in the modular world. please mr.doepfer take good
notice at what these features would offer to the control of the
A100. let's go guys and girls bring on those ideas and features.
