### 3/5 — Could be so much better

*2023-04-30*

Love the stock sounds and it gives me something to do when I am bored but don’t want to get hardware out… 

BUT:
- would love an option to copy/paste chunks patterns to save so much time from going in note by note

- no sound control option for the ear piercing GUI sounds

- would be great to be able to customize tones, even a little bit

### 4/5 — It’s really good app but..

*2022-10-25, version 1.2*

Yes it is a really good app but i do kinda have a problem with it when I got it it would make this really weird irritating noise and the start and the end and I don’t really like that so maybe you can fix that please?

### 4/5 — Janky—maybe a little… BUT!

*2022-06-11, version 1.2*

You can modify notes by hovering over the ones you placed to remove them. True, the dragging mechanic is a little frustrating but could be mastered.

### 1/5 — Nope

*2021-07-22, version 1.2*

Dosn’t work on current iOS update

### 5/5 — Yes

*2021-07-20, version 1.2*

THIS WAS VERY GOOD 😳👍

### 3/5 — Good with a bit of janky functionality

*2020-10-31, version 1.2*

I like the app, it works fine with exports, but placing notes on the piano roll is quite a chore because it automatically places a note when you stop dragging the cursor, and it’s a monotonic editor too so if you place a note below or above a spot where one already exists, it replaces that note, so that’s tedious. There’s also no sound preview within the app so I can’t playback the waveforms or the song I’m editing. Otherwise, pretty good mobile alternative to FamiTracker (a PC only chip tuning app).

### 4/5 — Nice app!

*2019-09-20, version 1.2*

I love this and i finally found a free and good app to make music with but can you add sounds to the black key or how do you do it if there already was sound?
