To improve sound quality, use an external Sound Module or for example the App Roland "Sound Canvas". All instruments of the "Sound Canvas" (SC-8820) are selectable. You can map all 128 GM instruments to other SC-8820 instruments.

Features of the "MIDI file player/recorder":
- MIDI files must be in the shared iTunes folder
- Plays MIDI files
- Records MIDI files
- 10 play lists (add, remove and move items)
- Auto next and random playing (MIDI file list and play lists)
- Loop function (wait time is adaptable by long pressing on loop button)
- MIDI Bluetooth LE supported (e.g. Yamaha MD-BT01)
- All instruments of the Roland "Sound Canvas" (drum set included) can be mapped to the General MIDI instruments.
- Plays and records at the same time e.g. for muting channels in a MIDI file
- Can be used as virtual instrument for your MIDI master keyboard, MIDI accordion etc.
- Plays and records additional instruments at the same time (needs MIDI interface like "iRig MIDI" and a MIDI instrument)
- You can change instruments, volume, reverb, chorus and panorama for each channel
- Transpose MIDI file (-5 to +6 half tones)
- Local sound ON/OFF
- Show system exclusive messages (SYSEX) ON/OFF
- Filter SYSEX messages ON/OFF
- Notify text field for informations
- Easy file selection and possibility to find or rename MIDI files
- Send MIDI file by Mail
- Automatic file import (e.g. from internet), when you chose "open in MIDI player"
- Customer "SoundFont" can be placed in the shared iTunes folder. The name must be "GM_instruments.sf2" and it must support the general MIDI sound set including drums. Large "SoundFont" files may not work. Use very small "SoundFonts", when you have an older iPhone or iPad. For this devices you can try e.g. the "bennetng_AnotherGS_v2-1.sf2"
- Integrated Help
- Background playing
- 32 chord types are detected and displayed
- The chords can be detected on all channels or only on a specific one

Known problems:
- No sound: Is the silent switch set to OFF or volume too low?
- MIDI files using nearly all 16 channels and a lot of resources may not sound correctly. Try to mute some channels/instruments. This happens only, when using "Local sound" and some instruments (e.g. strings, synth pad, effects).
- The sound quality is lower for older iPhones and iPads due to the smaller SoundFont size. If some MIDI files do not sound correctly, please use a small SoundFont like the "Scc1t2.sf2". On some devices (older iPhones or iPads) the "Bagpipe" sounds wrong in my ears.

A really useful app for choir members. The ability to mute some parts, transpose, and alter the pace of the music is great.

Fantastic * * * * *

That said, not found any better apps for the function (and I've tried 6 now, free and paid), so great work, many thanks!

This app is worth every penny. Just what I was looking for without any snags.

I like this app VERY MUCH. Ideal for learning choir parts, which is how I am using it at the moment. Customer Service is ABSOLUTELY EXCELLENT. Great Value.

Great App! * * * * *
von Ungeheur - Version - 1.1.1 - Feb 17, 2014
This is one of the most useful apps I have run across. Far more useful than a simple player. It's ready then to be used as my "accompaniment" when I play along with my trombone. Thanks for a really useful app!

Plays MIDIs Perfectly * * * * *
by ClarkJacob4 - Version 1.0.1 - Sep 6, 2013
Plays MIDIs perfectly, and it's a very good price. File manager has import feature from my other apps which is excellent as well.

No sound on iPhone 7 under latest release of iOS.

This app, which I’ve used since the iPad 2, has recently stopped working for me on my iPhone 7. It’s still an amazing app which still works on my iPad Air 2 and it has been my go to app to listen to the Original Doom OST since Doom Classic died along with 32 bit app support. Please fix this glaring bug.

Thanks for the feedback. Please contact me by mail (
Possible solutions for the "no sound" problem:
- Set the "silent switch" of the iPhone/iPad to "OFF".
- Set the volume with the side switches to a higher value, when the App is open.
- Set the "Local sound" software switch in the App to "ON", close the App completely and restart it.
- Close all App's completely and switch the iPhone/iPad completely "Off" (not only with the "OFF" button) and switch it "On" again.
Note: Not all steps may be necessary!

Blank spots. Cannot save.

Even with the March 2017 update, it still randomly stops making any sound--it will play a song beautifully, I will load another song from another app, and then neither the new song nor the old one maje any noise when I play them. The only solution I have found is to delete and reinstall the app.

When I download and play certain files from the internet, sometimes notes which I know should be there and that I can hear in other apps simply do not play.

When I copy a new file to the app using itunes with extension .midi, nothing happens. This isn't as bad as I thought since it recognizes files with extension .mid as MIDI files but is a liitle annoying.

It lets you edit the MIDI settings (instruments and volume for individual channels) but there is no usable way to save your work. The app designer seems to think I should record the whole edited song and then save that, but for a long song I do not have the time. Also my settings keep randomly reverting to the original settings so I have to make the same changes over and over again.

The sound on this is great, it sounds better than any other midi app I have tried. But it needs to actually play the notes that are there and there needs to be a way to get files onto the thing!

Thanks for your comments.
Please contact me by mail ( if you are interested on help. There are too much things, that I can't reproduce on my devices.
Please send me a MIDI file, which causes problems.
You are absolutely right, that it would be nice to save the edited song without recording it. When I knew how to do it, it would be integreated since a long time.

Developer very responsive and app works well with iCloud

We tried many programs to play midi files accessed from the cloud to a Yamaha Disklavier Mark IV with a bluetooth attachment to the MIDI in/out. This was the first one we could get to work. We had one problem...the volume was being set at 127, too high for our piano. We contacted the developer and in less than 24 hours he had created a new version where the default volume was set to 100, the max acceptable to the Disklavier. We appreciated the prompt response from the developer and feel this is an excellent solution for playing MIDI files.

Thanks very much for your kind words.
