MIDITrail is a MIDI player which provides 3D visualization of MIDI data sets. You can enjoy not only listening but also viewing. MIDITrail supports Standard MIDI File (format 0/1), CoreMIDI, and multiple MIDI ports. MIDITrail is available for Windows, macOS and iOS. Optional feature: You can enjoy the VR(virtual reality) experience using cheap VR glasses for smartphones and the game controller for iPhone. Requirements: iOS 12.0 or later (1) Preparing MIDI files You have to transfer MIDI files to your iOS device from Mac or PC. Connect your iOS device to Mac or PC, and launch iTunes. Then you can transfer MIDI files using 'File Sharing'. Or you can add MIDI files to MIDITrail using Files App of iOS. (2) Preparing Sound module You can use sound module which supports Core MIDI. And you can use internal wavetable synthesizer. There are three ways as shown below: The first way is to connect MIDI interface device and external sound module. (e.g. iRig MIDI, i-MX1, etc.) The second way is to use Synth App which supports 'Virtual MIDI Port' and 'Background Mode'. (e.g. KQ Sampei, bs-16i, Sound Canvas for iOS, etc.) The third way is to use the internal wavetable synthesizer. You have to transfer the wavetable file (DLS/SF2) to your iOS device in advance.
Good but no sound?
So when I play a .midi file the visuals work but there is no sound. Please fix this.
United StatesProblems
Great app! But wherever I import a crazy black midi it says that it’s not a standard file and whenever i get one to play I don’t hear anything
United StatesSound is muted
Sound won’t work but the midi display is cool.
United StatesGood but please fix this problem
The sound is always muted when I try to play a MIDI file. I don’t know when this started happening, but I think it’s making people mad. Other than that, very cool!
United StatesAlmost perfect
this app makes it so i can make black midi videos on ipad but theres one problem the notes be glitchy sometimes and the piano black keys are not right but still good app
United StatesGreat music visualizer
Great app. Would like it to keep playing when other MIDI apps are loaded, in the background if necessary, so that a synth in the foreground can be manipulated during song playback.
United StatesHelp
The audio won’t play
