+  SYSEX Midi Functions for the microKORG
+  As per the microKORG midi specification found here: http://i.korg.com/uploads/Support/MK1_633652915168960000.pdf
+
+  How does this work?
+
+  The data handled by the microKORG is in 'sets' with each 'set' composed of 7 Bytes with 8 Bits as such:
+
+  0b0000 0000
+  0b1111 1111
+  0bnnnn nnnn
+  0b6666 6666
+
+  this gets turned into 'sets' of 8 bytes with 7 Bits:
+
+  0b0654 3210 -- this stores the MSB of the following 7 Bytes
+  0b0000 0000
+  0b0111 1111
+  0b0nnn nnnn
+  0b0666 6666
+
+  In addition, the data is stored with an extra 2 Bytes, which gets converted into 3 bytes in the SYSEX format. 
+
+  Handily, they displayed this as:
+  CURRENT PROGRAM DATA (IN CURRENT BUFFER) DUMP FORMAT
+  254bytes    = 7*36+2    -> 8*36+(1+2)   => 291Bytes
+
+  It probably has something to do with dumping multiple programs as well as global settings, but I'm not handling those here.
