Drag and Drop Simplicity

The quickest way to play MIDI files – simply drag and drop a file, multiple files, a folder or folders containing MIDI files on to MIDIPlayer X.

MIDIPlayer X will remember your last MIDI destination, and can automatically start playback immediately – eliminating extra clicks or keystrokes.

MIDIPlayer X will display information about the file, including title, tempo, time signature, song position, as well as MIDI channel status and System Exclusive data.

MIDI Made Easy
MIDIPlayer X works with virtually all commercial MIDI hardware and software. It will locate all available MIDI outputs, both hardware and virtual, so you can select your desired sound source.

Easily switch playback between an external keyboard or sound module, or to other software instruments and apps inside your Mac.

MIDIPlayer X includes its own software synth using Apple’s CoreAudio technology. So even if you have no other MIDI hardware or software available on your Mac, you’ll always have a 16-part multitimbral, General MIDI-compatible synth available.
Move Freely Through Your Files & Songs

Move through multiple files quickly with a handy key command, or use Auto Play and Advance to do it for you.

Turn on Loop to seamlessly loop your drum or chord patterns.

Rewind and fast forward freely throughout your song – step one measure at time, or jump to any location with a simple click or drag. MIDIPlayer X will chase events to make sure your synth stays in sync with your song.

The counter displays precise song position in either bar : beat or min : sec format.

Customize and Save New MIDI Files

Mute or solo individual channels within your MIDI file with a single click – ideal for learning an individual part within your song, or when you want to mute the melody so you can play or sing it instead.

Rechannelize to move MIDI data to a different MIDI channel.

Change the tempo – the song’s entire tempo map moves up or down with your desired setting.

Once customized, save your song as a new MIDI file. Channel mutes, rechannelized data, and tempo settings will be retained next time you load your new file into MIDIPlayer X.
