Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog.

Unreleased

Added

  • User can drop preset instruments into os.UserConfigDir()/sointu/presets/ and they appear in the list of presets next time sointu is started. (#125)
  • Ability to loop certain section of the song when playing. The loop can be set by using the toggle button in the song panel, or by hitting Ctrl+L. (#128)
  • Disable units temporarily. The disabled units are shown in gray and are not compiled into the patch and are considered for all purposes non-existent. Hitting Ctrl-D disables/re-enables the selected unit(s). The yaml file has field disabled: true for the unit. (#116)
  • Passing a file name on command line immediately tries loading that file (#122)
  • Massive rewrite of the GUI, in particular allowing better copying, pasting and scrolling of table-based data (order list and note data).
  • Dbgain unit, which allows defining the gain in decibels (-40 dB to +40dB)

Fixed

  • 32-bit su_load_gmdls clobbered ebx, even though __stdcall demands it to be not touched (#130)
  • Spaces are allowed in instrument names (#120)
  • Fixed the dropdown for targeting sends making it impossible to choose certain ops. This was done just by reducing the default height of popup menus so they fit on screen (#121)
  • Warn user about sample rate being other than 44100 Hz, as this lead to weird behaviour. Sointu assumes the samplerate always to be 44100 Hz. (#129)

Changed

  • The scroll wheel behavior for unit integer parameters was flipped: scrolling up now increases the value, while scrolling down decreases the value. It was vice versa. (#112)

v0.3.0

Added

  • Scroll bars to menus, shown when a menu is too long to fit.
  • Save the GUI state periodically to a recovery file and load it on startup of the app, if present. The recovery files are located in the app config directory (e.g. AppData/Roaming/Sointu on Windows).
  • Save the VSTI GUI state to the DAW project file, through GetChunk / SetChunk mechanisms.
  • Instrument presets. The presets are embedded in the executable and there's a button to open a menu to load one of the presets.
  • Frequency modulation target for oscillator, as it was in 4klang
  • Reverb preset settings for a delay unit, with stereo, left and right options

Fixed

  • Crash when running more than one sointu VSTI plugins in parallel
  • The scroll bars move in sync with the cursor.
  • The stereo version of delay in the go virtual machine (executables / plugins not ending with -native) applied the left delay taps on the right channel, and the right delay taps on the left channel.
  • The sointu-vsti-native plugin has different plugin ID and plugin name to not confuse it with the non-native one
  • The VSTI waits for the gioui actually have quit when closing the plugin

Changed

  • BREAKING CHANGE: The meaning of default modulation mode ("auto") has been changed for cross-instrument modulations: it now means "all" voices, instead of first voice (which was redundant, as it was same as defining voice = 0). This means that for cross-instrument modulations, one "all vocies" send gets actually compiled into multiple sends, one for each targeted voice. For intra-instrument modulations, the meaning stays the same, but the label was changed to "self", to highlight that this means the voice modulates only itself and not other voices.

v0.2.0

Added

  • Saving and loading instruments
  • Comment field to instruments
  • Ability to reorder tracks
  • Add menu command to delete all unused data from song file
  • Ability to search a unit by typing its name
  • Ability to run sointu as a vsti plugin, inside vsti host
  • Ability to lock delay relative to beat duration
  • Ability to import 4klang patches (.4kp) and instruments (.4ki)
  • The repository has example instruments, including all patches and instruments from 4klang
  • The compiler templates are embedded in the sointu-compile, so no installation is needed beyond copying sointu-compile to PATH
  • Ability to select multiple units and cut, copy & paste them
  • Mousewheel adjusts unit parameters
  • Tooltips to many buttons
  • Support for gm.dls samples in the go-written virtual machine
  • x86 and C written examples how to play a sointu song on various platforms. On Windows, the examples can optionally be linked with Crinkler to get Crinkler reports.

Fixed

  • Unnamed instruments with multiple voices caused crashes
  • In the native version, exceeding the 64 delaylines caused crashes
  • wat2wasm nowadays uses funcref instead of anyfunc
  • In the WebAssembly core, $WRK was messed after stereo oscillators, making modulations not work
  • The Webassembly implementation of mono version of the "out" unit

Changed

  • The release flag in the voice is now a sustain flag i.e. the logic has been inverted. This was done so that when the synth is initialized with zeros, all voices start with sustain = 0 i.e. in released state.
  • The crush resolution is now in bits instead of linear range; this is a breaking change and changes the meaning of the resolution values. But now there are more usable values in the resolution.

v0.1.0

Added

  • An instrument (set of opcodes & accompanying values) can have any number of voices.
  • A track can trigger any number of voices, releasing the previous when new one is triggered.
  • Pattern length does not have to be a power of 2.
  • Only the necessary opcodes and functions of the synth are compiled in the final executable.
  • Harmonized support for stereo signals: every opcode supports stereo variant.
  • New opcodes: crush, gain, inverse gain, clip, speed (bpm modulation), compressor.
  • Support for sample-based oscillators (samples loaded from gm.dls).
  • Unison oscillators: multiple copies of the oscillator running with different detuning and added up to together.
  • Support for 32 and 64 bit builds.
  • Support different platforms: Windows, Linux and Mac (Intel).
  • Experimental support for compiling songs into WebAssembly.
  • Switch to CMake for builds.
  • Regression tests for every VM instruction, using CTests.
  • Compiling as a static library & an API to call Sointu
  • Running all tests (win/linux/mac/wasm) in the cloud, using Github workflows
  • Tools written in Go-lang:
    • a tracker for composing songs as .yml
    • a command line utility to convert .yml songs to .asm
    • a command line utility to play the songs on command line
