How to connect Midiclock to your midi software

MIDIClock can be used to synchronize multiple sequencers/synths.
You can do this using MIDIYoke (get it at www.midiox.com) :
Connect MIDIClock to MIDIYoke Junction 1 output. As MIDIYoke is a multiclient
driver, you can connect multiple sequencers/synths (such as rebirth, AN1x,…)
to MIDIYoke Junction 1 MIDI input.

By editing the clockpresets.ini file, you can achieve even more
advanced remote control of midiclock. Enable HexSpy to monitor the
incoming midi messages. It will help you determine which entries
you need to add to the ini file.

The BPM_PRESETS section contains the tempo settings for all patch selects.
You can add action codes to any of these entries.

Additionally you can add special commands which translate an incoming
midi message (such as midi control messages) into a midiclock action.
This is done in the SPECIAL_COMMANDS section.

The following target action codes can be executed on incoming midi commands :
(only usable by editing the ini file) :
0 = do nothing
1 –> 200 = set this specific BPM value
10000 = perform midi value to tempo transformation (see below)
10001 = start-stop
10002 = pause
10003 = continue
10004 = start
10005 = stop
10006 = decrease tempo
10007 = increase tempo

In case of action 10000 –> midi value to tempo transformation :
for the last byte you can use a specific value or
selectable range transformation from this list of presets :
Preset 0xF0: From 0×00 to 0×7F –> multiplier = 1.58 and offset = 0
Preset 0xF1: From 0×00 to 0×7F –> multiplier = 1 and offset = 0
Preset 0xF2: From 0×00 to 0×7F –> multiplier = 2 and offset = 0
Preset 0xF3: From 0×00 to 0×7F –> multiplier = 3 and offset = 0
Preset 0xF4: From 0×00 to 0×7F –> multiplier = 4 and offset = 0
Preset 0xFA: From 0×00 to 0×3F –> multiplier = 2 and offset = 0
Preset 0xFB: From 0×40 to 0×7F –> multiplier = 2 and offset = 0
Preset 0xFC: From 0×00 to 0×3F –> multiplier = 2 and offset = 50
Preset 0xFD: From 0×40 to 0×7F –> multiplier = -2 and offset = 306
Preset 0xFF: From 0×01 to 0×7F –> multiplier = 2 and offset = 0

An example in the clockpresets.INI file :

[BPM_PRESETS]
# this sets the tempo to 140 when program nr 1 is selected
PROGRAM1=140

# this sends start when program nr 2 is selected
PROGRAM2=10004

# this sends stop when program nr 3 is selected
PROGRAM3=10005

[SPECIAL_COMMANDS]
# this example enables using the modulation wheel to control the tempo
# F0 means the range transform setting accepts full controller range
# it sets tempo to (controller value)*1.58
# which maps the midi range 00-7F on bpm range 1 to 200
INPUT0=B102F0
ACTION0=10000

** use ACTION code 20001 for tap tempo message input
