Patch Parsing v2 (auto sync or request patch from mks)

[markusschloesser]

MKS-80 does not reply to edit buffer request. One editor requests all 64 patches of a bank by
SYSX: F0 41 41 00 20 4D 4B 53 2D 38 30 00 F7 ==> 5.1.2 Request a file (RQF) : 13 bytes
(SYSX: 240 65 65 0 32 77 75 83 45 56 48 0 247 (DECIMAL))
and then parsing the program number and parsing all 64 patches.

The reply from the MKS is 16 DATs

idea:

1. Sent program change (e.g. 12)
2. do RQF
3. filter reply for program number 12
