Note: I don't have mac so macOS build is not tested. If you find bug, please report it to github.com/ryukau/VSTPlugins.

Info: For Linux, LV2 version is available at github.com/ryukau/LV2Plugins.

EnvelopedSine is yet another additive synthesizer. This one computes 64 sine for each note, which is less than IterativeSinCluster, but has individual controls of attack time, decay time and saturation for each sine wave. EnvelopedSine is better suited for percussive sounds:

  • 64 sine wave per note.
  • AD gain envelope and saturation control for each sine wave.
  • Pitch controls which enables to make non-harmonic sounds.
  • Randomization for gain, pitch, attack/decay time, saturation and phase.
  • Unison mode to make stereo sounds.
  • Phaser with up to 16 of 2nd order Thiran all-pass filter.

looks promising - but afaics not studio one nor any sub-host sees the plugin - though it is scanned... thought i'd let you know...

Hi, thanks for the report.

Just in case, VST 3 plugins must be placed in 'C:\Program Files\Common Files\VST3''. DAW may not recognize VST 3 plugin when it's placed in VST 2 plugin directory.

I tried my plugins on Studio One Win x64. FX works without problem. However, all of my synth have problem.

There seems to be 2 problems.

# 1. Plugin Finding
On Windows 10, Studio One recognizes my plugins. So it's likely Windows 7 is causing some problem. I don't have Windows 7. So only thing I could provide is build instruction from source code.

If the instruction is not clear or you got any error while building, feel free to ask questions.

# 2. Noise on Synth Output
Studio One caused noise on all of my synth plugins. I found that VST 3 SDK example plugin (Note Expression Synth With UI) works without problem. So problem is most likely in my code. I'm not sure I could solve this in near future.

For your infromation, I tested my plugins on VST3PluginTestHost (Steinberg's host), FL, Live, REAPER and Bitwig. Studio One is currently the only DAW which caused this problem.

I fixed noise issue (#2). Latest Windows build including this fix is available here:

For issue #1, installing C++ redistributable might fix it. You can download it from the link below (vc_redist.x64.exe):
