How to make a synth bass in Circle2

Illustration: Jay Schaul

In this tutorial series, we walk through building some handy synth presets so you can hit the ground running with circle2 within minutes.

Start with an oscillator

Step 1

02-bass-01-Start with an oscillator

  • Choose “VPS” for the first oscillator.
  • Dial the vertical setting to about 70%.

Note: The vertical parameter controls the frequency component of the sine waves.  Increasing this parameter fills in more harmonics to create a brighter timbre.

Step 2   

  • Choose “Wavetable” for the second oscillator and turn the oscillator on.
  • Pick wavetable “classic triangle” as the second wavetable
  • Bring the crossfade down to 0.3

Tip: At the end of designing the sound, go back and play with different wavetables to try out other sounds.

Step 3

  • Choose “Analog” for the third oscillator and turn the oscillator on.
  • Make sure that the sine wave shape is selected.

Sculpt the Source

Step 4    

  • Head over to the mixer and increase the level of osc 2 to 0.8.

Step 5

02-bass-02-Step 5

  • Click on the “Settings” tab at the bottom of the synth.
  • Under “voicing”, drag the unison number from 1 to 4
  • On the upper left, increase the global detune to 0.05

Note: By increasing the global detune the sound will start “fluttering” as the pitch wavers, giving a thicker sounding patch.

Step 6

02-bass-03-Step 6

  • Head over to the green envelope to the top right of the synth.
  • Adjust the Decay down to 0.195 seconds
  • Adjust the Sustain to 0.9 seconds
  • Adjust the Release to 0.3 seconds

Dial in some effects

Step 7

02-bass-04-Step 7

  • Activate “Mouth Filter” in the middle MIXER/FX column.
  • Bring the Formant filter to 0.35
  • Increase the Out fader to about 90%
  • Take the Mix slider to about 45%

Tip: Try selecting different vowel sounds to create different timbres when moving the formant filter.

Step 8

02-bass-05-Step 8

  • Activate “Echo” from the bottom “Effects” tab.
  • Take the Mix slider down to about 20%
  • Take Out slider up to about 95%

Note: Adding a small amount of Echo will make the bass sound wider and bigger.

Step 9

02-bass-06-Step 9

  • Activate a “Shelving EQ” in the middle MIXER/FX column.
  • Give a slight boost to band 1 at around 63hz
  • Decrease band 2 slight at around 900hz

Modulate the synth

Step 10

02-bass-07-Step 10

  • Activate the second modulator (Purple) and switch it to “Envelope.”
  • Bring the Attack time to 0.006s
  • Bring to Decay to 0.24s
  • Lower the Sustain time to 0.25s
  • Bring the Release to 0.1s

Step 11

02-bass-08-Step 11

  • Bring the cutoff frequency of the middle filter (make sure it is at lowpass mode) to 140hz.
  • Increase the resonance to 1.3.

Step 12

02-bass-09-Step 12

  •  Drag the Purple Modulator (from the envelope) circle onto:
  • The Frequency parameter of the filter
  • The Mouth Filter
  • Osc 3 on the mixer
  • The vertical parameter on Osc 1
  • The x-fade parameter on Osc

Note: By modulating the frequency of the filter/mouth filter the “ow” sound is created. The timing of the modulator envelope (Purple Envelope) will need to be adjusted depending on the BPM you are using.
