I've been researching how to make Pro Presenter midi module work with mydmx but I haven't purchased mydmx yet. From my research, you can purchase Midi Module from Pro Presenter and in each PP slide you can set/send a midi note to your lighting control via Midi network. If you're running MyDMX on a dedicated PC machine, you just need rtpMIDI (free) driver to receive network midi signals.
Because of latency you'll need to run a gigabit switch.
The only confirmation I need is if rptMIDI which a virtual MIDI interface will be recognized by MyDMX Midi Triggering..
