This article will provide a step-by-step tutorial to create a vibrato-rise patch using BEAP. This means that this is not going to be a normal vibrato patch. The rise in pitch will lead to a faster vibrato.


What is vibrato?


Vibrato is a rapid but slight variation in pitch while holding a not for longer duration.It can be produced using an instrument, voice or both.


Here is a step-by-step tutorial on how to create a Vibrato rise patch using BEAP:



STEP 1: Pull out the following modules from BEAP and alter their settings as shown.


There will be a small ‘b’ symbol on the left side of the screen, which you can click to search for the following modules:


  • Oscillator



  • Choose ‘sine’ wave
  • Set CV2 to 10.2 %
  • Offset to 9.47 %


  • Keyboard



No change in settings.


  • ADSR



  • Attacks: 50 ms
  • Decay: 50ms
  • Sustain: 70%
  • Release: 500ms


  • VCA (Voltage Controlled Amplifier)



No change in settings.


  • Stereo



No change in settings.


  • CV LFO (Low Frequency Oscillator)




  • Phase: 0.00
  • Rate: 6.44Hz
  • CV Amount: 100 %


Importance of the ‘CV LFO’


As the name suggests, this a low frequency oscillator with a CV input. This provides the vibrato to the sound by going into the CV2 input of the Oscillator. The 1v/oct output of the keyboard goes into the CV input of the LFO, hence controlling the intensity of vibrato via the pitch change.



STEP 2: Patch all the modules according to the following instructions, referring to the picture below:



  • Put the 1v/oct out of the Keyboard into the CV1 input of the Oscillator.
  • Put the 1v/oct out of the Keyboard into the CV input of the CV LFO.
  • Gate out of the keyboard goes into the ADSR Gate in.
  • Signal out of the CV LFO goes in into the CV2 input of the Oscillator.
  • Oscillator signal out goes into the signal in of VCA.
  • Signal out of ADSR goes into CV in of VCA.
  • Output of VCA goes into left and right input of Stereo.


The patch is ready, as soon as you press the keys on the keyboard the vibrato starts, also higher the pitch the more intense the vibrato becomes.
