LFO Synth Module


  • • Modular

I am building Rack Extensions for Propellerhead Reason, mostly modular synth based, and inspired by VCV rack.

My goal is to provide a number of basic standalone modules as Rack Extensions for Reason that provide all the functionality needed to do basic Modular Synthesis, at no charge (ie., free).

Once I have a comprehensive set of modules I will release them in a self contained larger Rack Extension (or two or more if there are too many) for a small cost.

Product details

The Modrack LFO Rack Extension is a basic Low Frequency Oscillator module.

It features the following:

  • Simultaneous Sine, Triangle, Sawtooth and Square waveforms.
  • Analogue (wavetable based) or Digital signal switch.
  • CV input for Pulse Width
