23e8bc0c5f Remove bridge.newSynthState & add 1 to RandSeed during Render calls, so now an empty struct corresponds to the Sointu default behavior. 2020-10-28 20:03:21 +02:00

8183c698da Separate Synth and SynthState: SynthState is the part that Render changes.
This should make testing easier, as Synth can be assumed to stay the same
during each call. Synth is also the part that we can parse from .asm/.json file
and a Patch can be compiled into a synth. Synth can be eventually made
quite opaque to the user. The user should not need to worry about opcodes
etc.

64afa9fb48 Change the C-API to roughly match the new Go-API.
The parameter order is now so that all the in/out int parameters are in the end of the signature.

5f4b85b0a4 Change the Go API to have two versions: Render(buffer []float32), which always fill the whole buffer, and RenderTime(buffer []float32,int maxtime), which ends either when the buffer is full, or modulated time is reached. 2020-10-27 17:26:08 +02:00

470ba28592 Change the Render function in bridge.go to return a tuple of: number of samples rendered; bool indicating if rowend was reached; and a possible error.
The callbacks are gone; the row looping is the job of the user which is probably better for everyone.

6c90ba2067 Implement a song struct to hold all the information of a single song (corresponding one .asm file) and Render function for it. 2020-10-24 23:25:23 +03:00

aa133b4606 Change bridge.go so that there is just SetPatch(...) function, instead of having to SetCommands, SetValues etc.
Now the patch definition in bridge_test.go and test_envelope.asm appear quite similar, so it's clear how they are related.

1abc6f22d5 Change the Go bridge API to more idiomatic Go, offering a callback when the row advances. 2020-10-24 14:39:10 +03:00

6e85ff674a Change the sointu.h api to return -1, 0 or n>0 depending if buffer is full and/or row ended.
test_render_samples_api.c was added to test the api. bridge.go was modified to reflect that there is no need to check for row manually; su_render_samples already returns the information if a row has ended.

c9e8000c5f Remove the cmake magic to create bridge.go from bridge.go.in.
The bridge.go now just assumes that the library you want is built in the build/ directory. It's probably a lot better idea than using wherever the latest build was; this way the same build is always used for the library.

7aac3917b7 Implement a bridge to call Sointu from Go language.
The main interface is render_samples function, which renders several samples in one call,
to limit the number of calls from Go to C. This is compiled into a library, which is then
linked and called from bridge.go.
