Packed Data Format
Data is packed in 8 byte “packets”, with the MS bit stripped from 7 parameter bytes, and
packed into an eighth byte, which is sent at the start of the 8 byte packet.
Example:

This is why it takes 220 MIDI bytes to transmit 192 Program/Sequence data bytes, and 293
bytes to send 256 Waveshape bytes.
