Veikko Sariola 7a9ac3489b Add polyphonism support to bridge.go 2020-10-26 13:06:50 +02:00
Veikko Sariola 1d07b4f192 Change the .asm song format so it's a bit easier to parse, by replacing PORT and GLOBALPORT macros with LOCALPORT and GLOBALPORT. 
The LOCALPORT and GLOBALPORT just get numeric parameters (unit, port) and (voice, unit, port), respectively, which should be now quite intuitive as most of the time the port index is one of the parameters visible in the .asm file. Only a few units have extra ports beyond transformed variables. Overall, this should make the parsing of the .asm files a lot easier.

Veikko Sariola f495b0575a Fix bug in song.go: the note was pulled from the song data incorrectly. 2020-10-26 12:55:14 +02:00
Veikko Sariola debeaa181c Fix bug in song.go: len(s.Patterns) should have been len(s.Tracks). 2020-10-26 12:55:14 +02:00
Veikko Sariola acab824523 Update README.md 2020-10-24 23:36:56 +03:00
Veikko Sariola 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
Veikko Sariola be7a4e21f3 Optimize asm player size, removing one unnecessary instruction. 2020-10-24 22:07:58 +03:00
Veikko Sariola 3bb3e5c88e Fix su_render_samples to return correct values when built in 32-bit. 2020-10-24 17:04:27 +03:00
Veikko Sariola 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.
 2020-10-24 16:15:15 +03:00
Veikko Sariola 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
Veikko Sariola 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.
 2020-10-23 00:04:54 +03:00
Veikko Sariola 163af33c9b Add .cache/ to .gitignore. 2020-10-22 23:31:05 +03:00

Veikko Sariola af75dd38aa Add common build folder names to .gitignore. 2020-10-22 21:19:14 +03:00
Veikko Sariola 95b70018cc Fix all CMake tests passing on MinGW: consider minor (< 1e-6) errors in waveform shape successes. 
Such errors are due to floating point rounding errors.
 2020-10-22 21:19:14 +03:00
Veikko Sariola b9ec015b4a Document MinGW build commands in README.md. 2020-10-22 21:19:14 +03:00
Veikko SariolaandGitHub 06e8365c06 Update README.md 2020-10-21 09:50:19 +03:00
Veikko Sariola 7e3dc19c83 Add inverse gain to compressor. The inverse gain is applied to the signal before any compressor calculations. 2020-05-27 18:54:37 +03:00
Veikko Sariola c5b6e6e28c Move su_load_gmdls into the responsibility of the intro to call, anticipating multicore rendering so it is called once before all the cores are spun up. 2020-05-27 18:54:34 +03:00
Veikko Sariola 200937aa50 Fix single shot samples: only first half of them was getting played. 2020-05-27 16:21:49 +03:00
Veikko Sariola 8956f524c9 Only compile introspection.asm when SU_USE_INTROSPECTION is defined. 2020-05-27 16:04:52 +03:00
Veikko 5e05057240 Fix builds and tests to pass on Linux. 
Builds on both 32-bit and 64-bit executables and all tests (except gm.dls stuff obviously, which was excluded) pass on 64-bit Linux. Cannot test the 32-bit executables, as WSL does not support running 32-bit.
 2020-05-27 10:54:37 +03:00
Veikko Sariola b64723323f Move player.asm back to sointu.asm, as they were getting again pretty intertwined. 2020-05-26 21:36:06 +03:00
Veikko Sariola e049bf2dce Change loadnote to load values from [-1,1], to allow using notes for both positive and negative modulations. 
Also change SPEED to take this change into account.

Veikko Sariola 17c6afceb4 Fix bug that su_env_map was not compiled when using only compressor, and rename it to su_nonlinear_map. 2020-05-25 20:45:36 +03:00
Veikko Sariola 1f92373a63 Limit compressor stack use. 2020-05-25 20:39:10 +03:00
Veikko Sariola 1eb6974d5d Optimize compressor size. 2020-05-25 20:29:34 +03:00
Veikko Sariola 55d9ca0ffc Reverse the voiceno counter: now it starts from MAX_VOICES and decrements until 0. This way, the VM needs not know anything about MAX_VOICES. 2020-05-25 17:23:54 +03:00
Veikko Sariola a193b8b1ef Inline transform_values into the VM, leading to a slightly more efficient register use. 2020-05-25 16:59:15 +03:00

Veikko Sariola da52c10f7f Get rid of transformed values and use the header of the voice for that; saves _CX completely for the opcode. 2020-05-23 21:06:57 +03:00
Veikko Sariola 79b384a0d6 Clean up comments and some defines. 2020-05-23 16:02:29 +03:00

Veikko Sariola 6f06306f0c Re-engineer delay, to use stack for the delay WRK pointer and to support note-syncing transpose. 2020-05-23 15:05:38 +03:00
Veikko Sariola afbff66e36 Use strucs for stack locations, instead of hard-coding them everywhere. 2020-05-23 14:56:06 +03:00
Veikko Sariola 654e5868bc Implement support for 64-bit builds. 
The implentation is through a few macros to handle the fact in 64-bit, all addresses have to be loaded first to register and only offsets are ok. Also, push only supports 64-bit registers in 64-bit, so we have _AX, _BX, _CX etc. defines, which are eax, ebx and ecx on 32bit and rax, rbx and rcx on 64bit.

Veikko Sariola d328431413 Improve README. 2020-05-16 08:54:55 +03:00
Veikko Sariola 78d4cd50e8 Rewrote most of the synth to better support stereo signals and polyphony. VSTi removed as there is no plan to update the VSTi to support the new features. 
The stereo opcode variants have bit 1 of the command stream set. The polyphony is split into two parts: 1) polyphony, meaning that voices reuse the same opcodes; 2) multitrack voices, meaning that a track triggers more than voice. They both can be flexible defined in any combinations: for example voice 1 and 2 can be triggered by track 1 and use instrument 1, and voice 3 by track 2/instrument 2 and voice 4 by track 3/instrument 2. This is achieved through the use of bitmasks: in the aforementioned example, bit 1 of su_voicetrack_bitmask would be set, meaning "the voice after voice #1 will be triggered by the same track". On the other hand, bits 1 and 3 of su_polyphony_bitmask would be set to indicate that "the voices after #1 and #3 will reuse the same instruments".

Veikko Sariola 9546574f13 Add regression test for AUX output. 2020-05-03 11:21:09 +03:00
Veikko Sariola c63dfd74f9 Make transform macro definition slightly more readable. 2020-05-03 11:12:53 +03:00
Veikko Sariola 53a1be9b61 Refactor all values to have a universal support for modulations. 
The modulation is now always added during value transformation.
With this, a lot of *_MOD defines could be removed.
The waveform for some tests changed slightly, because when the
value is saved to memory after modulating it, there is some
rounding errors.
