Unity DSP Graph Modular Synth is an experiment in creating modular synth using Unity's DSP Graph preview package. It uses modified DSP Graph 0.1.0-preview.18 which allows inputs and outputs to remain disconnected so that it's easier to leave nodes without every input/output connected. A lot of things in this project are directly inspired by VCV Rack.

• DSP Microphone Input
  Naive implementation of microphone input in DSPGraph. Uses IAudioKernelUpdate to copy data from microphone AudioClip.
• DSP Synthesizer Code
  Organs-like synth assembled in code with Scope and Spectrum preview on screen.
• DSP Synthesizer Graph
  The same organs-like synth assembled in xNode graph, which allows easy realtime manipulation during playback.
  Hear this synth sound sample:
  

• ADSRNode
  Simple linear ADSR envelope.
• AttenuatorNode
  Multiplies amplitude of input signal by factor.
• MergeNode
  Merges multiple mono inputs into single polyphonic output.
• MidiNode
  Used MidiJack's native library to process incoming midi events and translate them into signal outputs (Gate, Note, Retrigger).
• MixerNode
  Mixes polyphonic input into single mono output.
• MonoToStereo
  Takes two mono inputs and outputs stereo output.
• OscilatorNode
  Oscilates at given frequency using sine, triangle, saw or square wave. Can be modulated by fm input or pitch input from MidiNode. Supports multiple oscilators in polyphony mode.
• ScopeNode
  Used for drawing scope data.
  
• SpectrumNode
  Used for drawing spectrum data.
  
• SplitNode
  Splits single poly input into multiple mono outputs.
• VCANode
  Multiplies two inputs together and outputs result.
