Upon starting such a macro a predefined MIDI command is being sent. For the available commands see https://en.wikipedia.org/wiki/MIDI_Machine_Control however it depends from the device/software which commands are supported.

The GoToStart macro is an example how to alter this to a particular timestamp:

• the message F0 7F 7F 06 44 06 01 00 00 00 00 00 F7 comprises of
  • F0 F7 ⇒ Universal Real Time SysEx
  • 7F ⇒ device ID. 7F is all devices
  • 06 ⇒ MIDI machine control command
  • 44 ⇒ GoTo
  • 06 ⇒ length (6 bytes to follow)
  • 01 ⇒ target (usually 01)
  • 00 00 00 00 00 ⇒ hours minutes seconds frames subframes (hexadecimal!)
  • F7 ⇒ end of Universal Real Time SysEx message

This way you can easily create your own macros to jump to a particular time: simply replace the 00 00 00 00 00 with the timestamp you want to jump to.

Various timestamps are used in the file mmc_settimecode.xml

1. make this macro available
2. for general information about using MIDI to control other devices see MMC - MIDI Machine Control
3. depending from your setup you might need to use virtual MIDI patchcords like LoopMIDI or rtpMidi, see Software List
4. sending out MIDI e.g. over USB or network is supported from Titan v13 on
