Changelog

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

The format is based on Keep a Changelog.

Unreleased

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
