Introduction: Modular Keyboard Workstation/midi Controller W/ Modular Keybed
from my scratches .. من خربشاتي
midi_controller_work_station_64 ideas blueprints - first steps
unit used in inches
raise the precision to 1/64"
black keys are not sketched .. just consider 1/16" gap at each side of a black key
keybed construction is very modular:
64-keys consists of two main subsets of 32-keys ..
main_subset1: A0 to E3 & main_subset2: F5 to C8
then each set is divided into 3 subsets
main subset1 devides into
subset1: 8-keys A0 to E1 ..
subset2: 12-key (an octave inverted) F1 to E2 ..
subset3: 12-key F2 to E3
main subset2 devides into
subset4: 12-key F5 to E6 ..
subset5: 12-keys F6 to E7 ..
subset6: 8-keys F7 to C8
for 76-keys version add a 12-key subset7 attached to either main_subset1 F3 to E4 for example or attached to main_subset2 F4 to E5
for 88-keys version add an onther 12-key subset8 attached to the other main_subset, for example main_subset1 F3 to E4 if free or attached to main_subset2 F4 to E5
for 76-keys version (inverted) ...
swap the 8-keys subset1 in main_subset1 with 8-keys subset6 in main_subset2 & then invert the keys allocation .. then swap 12-keys subset2 with subset5 & subset3 with subset4 & maybe attach subset7 to the other main_subset
.. then consider each 12-keys subset to be consisted of two subsets: 7-keys F to B & 5-keys C to E ..
swap these two subsets within the same 12-keys subset then reallocate the entire keys of those 7-keys & 5-keys subsets to be inverted
and with respect to the matrix scanner or the under-keys sensor boards
take it as 4x2 matrix for the 8-keys subsets (A0 to C1 & C#1 to E1)&(F7 to G#7 & A7 to C8)
and 4x3 for the 12-keys subsets (F to G# & A to C & C# to E)
and consider the 12-keys as a whole subset and consider to group each main_subset with each other by connections then treat each main_subset with scanner board as one matrix or scan each subset by itself
