For my reese bass sound I used a combination of FM and subtractive synthesis to give a wobbly bass.
The basic steps are below
- OSC 1
- choose a Pulse width wave detune the pitch to -12 (i.e. 12 semitones being an octave lower). To add extra depth to the final sound detune the pitch further by -3 cents (this is found to the right of the Pitch control)
- choose your preferred number of voices (I went for 2) and modify the detune to about 5%. A lower number of voices and detune setting will help the bass to cut through in the final mix.
- OSC 2
- choose Basic shape & detune 2 octaves (-24 semitones) and adjust the pitch by +3 cents to offset the detune of -3 cents in OSC 1
- Use the preset ADSR so the bass reaches full volume immediately before it sustains and decays
Now you have a basic bass start manipulating and shaping the sound and create a ‘wobble’.
- Filter 1
- Filter 1 will be used create a wobble to the bass using a low pass filter (analog 12dB)
- Increase the drive to taste and keytracking to open up the filter more or the lower notes but less on the higher notes by turning the knob anti clockwise.
- LFO 1
- LFO 1 will be used to modulate the filter to give the wobble.
- Choose a triangle LFO and drag LFO 1 onto Filter 1 to control its sweep.
- Remember to set the LFO to Sync mode to Sync with your DAW’s tempo otherwise the wobble will be out of sync with your drums
- Filter 2
- Adjust filter 2 to taste I went for an analog 24DB low pass filter to create a steeper cut-off.
The finishing touches: effects and sound shaping to your taste..
- If desired, add Glide, Octave Scale and legato to get the pitch glide between notes
- Adjust the Spread; mono is probably better.
- Try assigning Random 1 to filter 1 and 2 to add nuances to your sound
- Add distortion and flange as required
- Consider adding macros to control the distortion drive & mix or the flange feedback and Dry Wet sounds
