## Music Check Description
MusicCheck is more than a normal midi controller, with our unique Prisma Composer you can systematically create or modify a melody in a 3-step process:
1. Specify chords allowed in your melody.
2. Choose a rhythmic pattern for your melody.
3. Finally select groups of notes you want to vary.
MusicCheck runs through all possibilities, for example with 10 chords and 6 groups there are a million different possibilities!!!!!!
We use a flexible prism coloured graph representation of all the different possibilities.
You can further configure the possible variations by restricting groups to certain chords.
Save and load Midi projects and extract the different chords with the Prisma-Composer or connect your Midi Keyboard and record new songs.
With a simulated turntable you can control the playback of your songs or play them backwards.
This mobile Midi-studio is able to load SF2 and DLS SoundFonts or you can start right away with some built-in instruments.

## Music Check Reviews in United States

### ****- "Esoteric oddity"
I treat this without any midi expectations. A totally fresh approach to strange harmonic choices. I admit I don’t know what is actually happening, besides the looper. It’s 20$ for some features but there is a mad hatters playground for free. A tutorial would be nice. Hails!
-- Oceans in space, 2024-08-30

### *---- "Terrible app."
It wouldn't let me import midi files or sf2 files. What a ripoff!
-- nobody227272827, 2022-10-22

### **--- "UI"
Cannot figure out what to do bc ui looks very bad
-- Johnathan1993737377474, 2022-06-29

### ****- "i love it but"
i love that this app can play soundfonts, but i don’t really like the velocity thing built in. i would give it a 4.5 if i could.
-- gavinf2012, 2022-01-01

### *---- "$75 dollar IAP?"
is that for real?
