thank you for your reply. When i understood everythinfüg correct so i only can start and stop a midi file with setlistmaker?
Set List Maker can't play MIDI files, but if you have another app that can play MIDI files and respond to MIDI messages, then you can control that app from Set List Maker using whatever MIDI messages it supports.
Sweet MIDI Player is one app that other people have used for this.
Does i have to start every midi at the beginning of the song or can i define a trigger?
You could send the MIDI message by tapping a button on the screen, pressing a remote foot switch or other controller, or setting up an automation track that sends the MIDI at a specific time after you select the song.
Can i also trigger dmx for light?
Yes, you can control DMX controllers if they support MIDI input.
Basically, Set List Maker can send any MIDI message, so the trick is finding out what messages your target device can respond to so you can enter them into Set List Maker.
