For those who feel bored on those dark winter days.
This application is just the port of the mk_sid_random.pl script (and TL’s patch manager) - if you don’t want to use these comfortable PC based programs, but if you are searching for a standalone solution, then this application could be interesting for you:

===============================================================================
This application generates random patches for the MIDIbox SID
It just requires one core module, a button to “fire” the random patch,
and a “true random generator”, e.g. based on http://willware.net:8080/hw-rng.html
The random generator has to be connected to pin RA0 of the core module (J5:A0)
The button to pin RC3 (J6:SI) - a pull-up resistor is already installed
there.
The MIDI merger is enabled by default, this allows you to connect
the random generator between a keyboard/PC and your MIDIbox SID.
The additional latency is about 300..400 uS
Random constraints can be edited in sid_random.c
===============================================================================
A precompiled binary is already part of this package:
o project.hex (can be loaded into MIOS Studio)
o project.syx (can be loaded into any SysEx upload tool)
Following tools are required to recompile the code:
o SDCC v2.5.0
o gputils
o perl
The details are described under http://www.ucapps.de/mios_c.html
===============================================================================
Required hardware:
o one MBHP_CORE module
o one button connected to pin RC3 of the PIC
Optional hardware:
o random patch will also be generated when any button of a DINX4
module has been pressed
===============================================================================
Configuration steps:
o check the “general application settings” in main.h if changes are
required for your hardware setup (e.g., if no AINX4 multiplexers
are connected to the core)
o the application can be rebuilt with the “make.bat” file
(type “make” in a DOS command shell)
o Hint: unused analog inputs must be tied to ground, otherwise
the core will transmit a lot of random CC events
===============================================================================
Description about the most important files:
- mios_wrapper\mios_wrapper.asm and mios_wrapper\mios_tables.inc:
The MIOS wrapper code and MIOS specific configuration tables
- pic18f452.c: exports PIC18F452 specific SFRs
- main.c: the main program with all MIOS hooks
- sid_random.c: generates the random patch
There are additional .h files for all .c files which contain
general definitions and the declaration of global functions/variables
These .h files must be included into the program parts which
get use of these globals
