VST 3 Examples

The SDK includes some Plug-ins and Host implementation examples: the Legendaries AGain and ADelay Plug-in ADelay, thanks Paul Kellet the OpenSource mda Plug-ins, a basic Note Expression Synth Plug-in supporting "Note Expression Event" and an example of pitchnames support Plug-in (PitchNames Plug-in) and...:

Note: They use cmake as project generator: How to use cmake for Building VST 3 Plug-ins order to add your own plug-ins check: How to add/create your own VST 3 Plug-ins

ADelay Plug-in

Very simple delay Plug-in:

  • only one parameter (a delay)

Check the folder public.sdk/samples/vst/adelay of the SDK!


AGain Plug-in

The SDK includes a AGain Plug-in which is a very simple VST 3 Plug-in. This Plug-in:

  • is multichannel compatible,
  • supports bypass processing,
  • has an automated gain parameter,
  • has an Event input bus (allowing to use noteOn velocity to control the gain factor),
  • has a VU peak meter,
  • uses the VSTGUI4 library
  • a version of this Plug-in with side-chaining is available (showing a Plug-in using the same controller and different components)

    • Sub-Bass Synthesizer: Several low frequency enhancement methods
    • TalkBox : High resolution vocoder
    • TestTone : Signal generator with pink and white noise, impulses and sweeps
    • Thru-Zero Flanger : Classic tape-flanging simulation
    • Tracker : Pitch tracking oscillator, or pitch tracking EQ
  • Instruments (1 Event input, 1 stereo Audio output):
    • DX10 : Sounds similar to the later Yamaha DX synths including the heavy bass but with a warmer, cleaner tone.
    • EPiano : Simple EPiano
    • JX10 : The Plug-in is designed for high quality (lower aliasing than most soft synths) and low processor usage
    • Piano : Not designed to be the best sounding piano in the world, but boasts extremely low CPU and memory usage.

Based on the OpenSource mda Plug-ins (http://mda.smartelectronix.com/), this set of Plug-ins demonstrates how wrap DSP code in a VST 3 Plug-in.
