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.

Requirements: iOS 8.0

(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'.

(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. Sound Canvas for iOS, bs-16i, 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.

I love this app, but two big problems.

I love this app, but there are two big problems that annoy me.A LOT. Not enough to make me uninstall or anything, but annoying nonetheless.

1.) Multi-track recordings don't work properly and only play one track. Maybe this is because I don't have it synced up to midi, I don't know. Also a lot of times it seems very out of sync I'm multi-track.

2.) If you were to make something stupidly fast, say, 500 BPM hemidemisemiquavers, then there will be a constant pitch that plays, even when the song ends, and even in the main menu. The only way I've found to fix this is to exit the app or play a different song that isn't as fast.

Fix these things and I'll be very happy!
