Create your own authentic 8-bit songs and sound effects by adding a timeline of notes, or an arrangement of loops. Share your awesome tunes with friends by exporting to an AAC audio file, 6502 ASM6 assembly code, NES Sound Format file, or an NES ROM file!

4 channels are available:
- Square Wave 1
- Square Wave 2
- Triangle Wave
- Noise

Each channel can play one note (or noise event) at a time. Square wave channels have 4 duty cycle parameters. and the noise channel has 32 adjustable noise presets. These parameters, as well as volume, are all adjustable at the channel or individual note level. Several example songs are included if you're just getting started and want to learn more.

- Loop-based or linear song arrangements
- Export to AAC audio file
- Export to 6502 ASM6 code
- Export to NES Sound Format (.nsf) file
- Export to NES ROM (.nes) file
- Multiple windows on iPad
- Dark mode and light mode
- Drag and drop support for notes and loops
- Adjustable tempo
- Adjustable zoom
- Cut, Copy and Paste
- Bulk note edit (transpose and volume)

What’s New

Version 1.12

- Fixed an issue in exported .nes or .nsf files, where audio may stop playing before the end of the song

Wow, really nice

UPDATE: Thanks for the reply! Double-tapping cells is currently how I am entering notes, but it would be much quicker if the note editor just stayed open until I closed it manually (e.g. with an ‘x’ button) or if there were buttons to move to the next/previous note (← / →) within the note editor.

Entering notes is very slow and involves mostly waiting for (standard system framework?) animations to finish. Otherwise a very cozy tracker at this price. Simple and well thought-out, with some very handy macros. Export to various formats is 👌.

UPDATE: I’ll look into what it would take to keep the note editor active, and allowing for moving around between notes while it’s onscreen (possibly including an option to adjust this behavior). The biggest hurdle I can think of is landscape mode for small phones, where the note editor UI is already a little cramped, but it might still be doable.

Thank you for your review! Starting in 1.8, you can also double-tap for certain actions to avoid the built-in delay of the press-and-hold context menus. For example, you can double tap to add notes or loop instances to an empty spot in the timeline, or to navigate into a loop instance on the timeline in the full song view. I will also check if some of the animations can be sped up, particularly when bringing up the note editor view.

Like this but needs improvement

I like this, you can make awesome chiptunes on this app but what it needs is to fix the triangle section, the triangle doesn’t sound right so I was wondering if you could make the triangle sound accurate 😄

Developer Response ,

Thank you for your review! I was wondering if you could send an email to octoberchiptuneios@gmail.com with more information on what you're hearing with the triangle channel.

Feature requests

Great app! Really enjoying it.

Would you consider adding controls for the envelope and sweep on the pulse channels per NES APU specs? The combination could be used to customize the sounds further.

I’ve found the drag / drop to be a little temperamental. Sometimes the app tries to scroll when I want to drag a note.

Would you consider a mode to create/edit a note on long press? Or do it via a gesture? The context menu is ok - just slows the process a bit.

Any suggestions for creating distinct notes? I’ve tried shortening by a 16th or manually decreasing volume over time. If there were an option to release a note just before it’s duration (simulating lift) that would be helpful.

Developer Response ,

Thank you for the suggestions!

I agree not having sweep and envelope control are big omissions. When I was first building the app, these features were a little beyond my own understanding. I’m using some simple equations to generate the different waveforms right now, and I’d need to do some research into how the waves would need to change based on sweep and envelope. It’s not in my plans for the short term, but it is definitely something I want to add, because without it, it’s harder to give a song more personality.

I’m also looking into some ways to make it less work to add notes, but I just want to do it in a way where accidental input doesn’t happen too often. But perhaps I’m placing too much importance on avoiding accidental input, and not enough on just making it easy. There is a an undo feature, and a lock switch on the toolbar, so making note entry as frictionless as possible should probably be a higher priority for me.

I find that using faster tempos helps with having more control over the sound, especially on the noise channel. And on the square channels, the faster tempo allows placing multiple notes after another for switches in duty cycle and volume, which can give the notes a little more character. But I agree it’s not ideal, and having full control over the APU capabilities is the right way to go.

I have some ideas on why drag and drop is finicky and I will be looking into that soon.

Thank you again for your rating and I will keep these suggestions in mind as I work to improve the app.
