iphone/ipad app that plays midi file (piano accompaniment)

I read from this forum a while back about getting midi file for the piano accompaniment for practice. The good thing about it is that you can adjust the tempo which is not doable with mp3 version. Kids tend to play fast and having a slow accompaniment would naturally slow them down. So now I got the midi files. The next step is to find an app that makes decent sound, imports midi file and adjust tempo. It seems easy but I haven’t been able to find one. The apps out there are all so expensive—at least 12 dollars, plus a bunch of in-app purchases, some of them are 100 dollars! I don’t want to just buy them one by one to try out. So I thought I’d post to ask for opinions.

I don’t need any fancy functionality, just:

  1. imports midi file;
  2. play midi file;
  3. adjust tempo;
  4. decent sound quality

Is there such a thing?

Well, sort of. GarageBand can be made to do this, with considerable effort:

I really like the website www.promusicapps.com. It has a lot of music apps all under one roof. There is a section specifically about apps for MIDI and some are rather inexpensive. I also agree with Robert’s suggestion, though it does take a little more effort. I suppose once you get the hang of it, you will probably be able to do it with your eyes closed.

It sounds like you already have the Midi Accompaniment CD Roms which allow you to download the files onto your computer and use the program included on the CD rom to change tempo?? I don’t think it can transfer to your phone though. Because it needs the program to slow the tempo. You could make a recording on your phone of the computer playing the piece but I can imagine the sound quality would be pretty bad.

The Midi Accompaniment had helped my students enormously. However, I’m having a horrible time getting Macs to adjust the tempo (which is the big benefit of the accompaniment files).
Anyone with Mac experience??

There is a free app called “Tempo Slow”. You can slow down any track you have on your iPad/iPod/iPhone through the app. (Or tracks you have on Dropbox, or over wifi) You can also save the slower tempo and email it to a student for practice.
You can also tag part of a track as a practice spot. Works great for things like Vivaldi Concerto spots to have a small part for slower practice.
