Hi!

I would like to play a MIDI file through a USB-MIDI converter and an MP3 through jack.&nbsp; I need them to start at the same time.

Do you know a proper way to do this?

Thanks!

Hi and welcome!

If you require normal audio output (not mp3, which is a digitally encoded format) in conjunction with synchronized MIDI note output, any DAW should be able to do it. The VSTs/VSTis would convert internal MIDI to audio (“through jack”) and you could also have a plain “MIDI track” outputting the associated MIDI notes to any USB MIDI interface.

What will also work in the MIDIbox context is to use a MIDIbox sequencer, output MIDI notes to any MIDI OUT, attach a synthesizer to that port via MIDI, grab its audio from its audio output port and the associated MIDI data from its MIDI THRU port.

Have fun and many greets!
