Pitch Trainer

Inspiration

I've always wanted to be able to do improve of the piano, and I think if I had perfect pitch that'd be a whole lot easier to do than just knowing chord progressions, so I thought this would be a good tool to help me toward this goal

What it does

It's mostly a guessing game. The App calls the wolfram API to get a MIDI key, as well as the note and octave the key belongs to. From there, I have a MIDI sampler that was made with AVFoundation, and a lot of googling. You then tap the staff to hear the Note, and guess away.

How I built it

I used mostly Apple's stack, and I used wolfram to get information on each note. I also used a lot of caffeine.

Challenges I ran into

I couldn't think of what to work on until Saturday so time was a challenge, and I was way passed finding a group so working alone was also kind of daunting. Also, parsing JSON with swift was a lot harder than I thought it would be (I should've looked for a framework).

What I learned

Wolfram API calls
Parsing JSON
AVFoundation and using MIDI with Apple
Async with iOS
App Transport Security
Labels need strong outlets if you want to change them.

What's next for pitch-trainer

First I'd like to add support for Sharp/Flat keys. I'd also like to add support for Chords. There is also a lot of cleaning up that needs to be done in the code base, it's a mess.
