Implementing music

[MS-DOS]

Hi everybody, I program a game with cc65, the music composer writes his music on famitracker. So I tried famitone to implement the music but a lot of effects are not compatible with famitone, so text2data does not want to create my .s file.

So how could I implement it without famitone?
(I did not find information by searching on google, even in assembler.)

Thank you for your answers.

If you want full support of Famitracker, maybe just use famitracker's NSF driver directly instead of using famitone?

[MS-DOS]

Oh yes, I did not know that famitracker had done a driver. Thank you very much.

What you have to watch out for is that famitracker's driver uses a lot more resources (more cpu time, etc). That may be fine for a small game, but may not be appropriate for a bigger project.

Two big drawbacks of using the FamiTracker driver straight up are ROM size and lack of sound effects.

Which effects are used, and how many instruments are used? I may be able to recommend a way to shoehorn the effects into FamiTone2 or another driver that supports other effects.

Indeed famitracker driver requires a lot of resources, the musics need 7 instruments, for the effects there are Axx, 4xx and Cxx for now.

I hope you don't mean 7 simultaneous voices. Though, you seem familiar with Famitracker, so maybe you mean 7 "Famitracker instruments", which is fine.

When someone talks about a MIDI file with 7 instruments, they mean simultaneous play, that is why I'm confused.

Here's my advice for each of the effects you mentioned.

Pently:

• 45y (vibrato at rate 5, depth y) is supported for musically sensible values of y.
• A0x (volume decrease) can be baked into an instrument's volume envelope, especially its decay phase.
• C00 (stop playback) is supported.

FamiTone2, GGSound:

• 4xy (vibrato at rate x, depth y) can be baked into an instrument's pitch envelope.
• A0x (volume decrease) can be baked into an instrument's volume envelope.
• C00 (stop playback) should be supported; if not, use D00 (pattern break) and loop on a silent pattern.

Ah thank you very much for this post, it will help me well.

If you really want to use the famitracker driver and have SFX support, you can use it with Shiru's SFX part of famitone.

Works fine for me.
