### 8Tones - the mobile chiptune maker

- Quote

Post by supernovamfgg » Wed Mar 23, 2016 9:19 pm

If any of y'all heard of a chiptune maker I was making last year (url: http://www.famitracker.com/forum/posts.php?id=6950). I have updated the app itself and published the iOS version.
Android Google Play Store: https://play.google.com/store/apps/deta ... ones&hl=en
Android Amazon App Store: http://www.amazon.com/gp/mas/dl/android ... eighttones
iOS App Store: https://appsto.re/us/O0ojbb.i
I am thinking about adding more features. But since it was made with Game Maker Studio it do have a lot of limitations. However I am thinking about export and convert the project itself as ftm and/or nsf but sadly I have no knowledge of how to write an ftm/nsf file.
EDIT 3/24/2016: Here is a PC version if you want to try it out:

Good news is that the PC version now has the capabilities to export your current project as text file that's compatible with Famitracker. While in the editor mode, press [T] on your keyboard to export the current project. And once it's done exporting the text file you can import that to Famitracker (has to be the latest version 0.4.6).
EDIT 3/25/2016: I have updated the Android version (Google Play) where you can export your project as text files as well! Amazon App Store version will be updated very soon!

B-but.. I thought you said you were not going to update it any longer unless it has a lot of downloads and feedback! I'm glad this is updated now! I've been playing around with this mobile tracker last year and I loved it!

Yes I mentioned that. But since I have tons of downloads I decided to resume the support.
I have almost 7000 users installed my app: http://imgur.com/Ps6gRsc
What I am interested is how to write the current project as NSF and/or FTM file since the engine I am using is capable writing a raw text file. If anyone have the knowledge and able to help me learn how to do that, that would be very appreciated.

Is the Windows version still available?
The fastest way would be writing a FamiTracker-compatible text file which could be imported back into FamiTracker. The manual comes with a page describing all text macro commands.

Windows Phone version? Yes but since the major update of Windows 10 universal store I have more hard times uploading it to the store. But I'll figure something out.
And if you're asking for the PC version, I am thinking about making one soon.

By the way, would you mind uploading the looped samples? It seems most of them on octave 3 or above do not loop perfectly, so far example the 25% pulse C-4 contains a C#3, and the 25% pulse C-5 contains a D-4, but I do not know if this is a limitation in whatever sound library you use or just the samples are not seamless.

Here are the samples from the attachment, I have ripped them directly from Famitracker (saved as .wav file and edited using Audacity). I have looped these samples in Audacity and they seems fine. But I do know the fact that Game Maker: Studio isn't that good looping short samples. I am considering making longer samples so they can loop seamlessly.

Yes, the samples are inconsistent; for example, for the C-5 samples,

- snd_C5_125.wav has 168 ÷ 4 = 42 samples per oscillation;
- snd_C5_25.wav has 85 ÷ 2 = 42.5 samples per oscillation;
- snd_C5.wav has 344 ÷ 8 = 43 samples per oscillation;
- snd_C5_t.wav has 338 ÷ 4 = 84.5 samples per oscillation.

This leads to a number of problems:

- Notes in different waveforms and octaves become out of tune to each other;
- Since these samples are ripped from FamiTracker then truncated, any non-integer samples per oscillation count results in an undertone as if the whole wave is a single oscillation;
- Game Maker samples might work better if their lengths are exact milliseconds (easier at 48 kHz sample rate), though I have not verified that.

Using Game Maker's buffers to synthesize sound streams might be a pain more than it is worth, so longer samples should suffice.

Yes that would be rather difficult to accomplish by generating raw wave files. However I have been messing around with my own source and went through carefully on text export from Famitracker, I have managed to make my app to export Famitracker importable (MMC5) text files!
Here is a PC version if you want to try it out:
https://www.dropbox.com/s/jwh5eongnetzl ... t.zip?dl=0
While in the PC editor mode, press [T] to export the current project. And once it's done exporting the text file you can import that to Famitracker (has to be the latest version 0.4.6)
I have tested 4 songs and so far it's working fine. But please let me know if you've encountered any issue(s).
Edit: to be honest, I personally don't know how to create a buffer in Game Maker. Maybe some helps would be really appreciated!

It would be really rad if you made it where you can import the files into 8tones as well so you can flip flop working on the computer and your phone.
