Five Must Try Circle² Techniques / Hugh on June 10th

Must Try

1. Vinyl stop FX

Circle²’s Echo effect module can be used to create vinyl stopping style FX. Firstly, load up any basic bass patch then set a continuous arpeggio running (by selecting Hold and pressing a sequence of notes). Next, turn on an LFO and drag it’s modulation circle to the time parameter of an ‘echo’ effect - turning the ‘echo’ mix slider up to full. Hey presto - instant turntable scratching style FX! For further refinement, experiment with the Echo delay time and LFO modulation rate settings.

2. Self oscillating filter

When some analog filters are used with extremely high resonance settings, they begin to self-oscillate, becoming their own sound source… Circle²’s analog modelled filter behaves in the same way, so make sure you know how to harness this technique! Firstly, set up a new patch with no oscillators turned on, then turn on the filter and push the resonance to full. Lastly, assign a randomised sequencer to modulate the filter frequency. Go ahead and layer with oscillators for an out of this world sound.

3. FM synthesis

All Circle² oscillators can also be also be used as modulators… That is - extremely fast LFOs. For FM synthesis (frequency modulation), we turn on 2 sine oscillators, then drag the second oscillator modulation circle to control the coarse tuning of the first. Next we set the coarse tuning of oscillator 2 to -24, and its level to 0. Now experiment with different oscillator shapes and tuning settings.

4. AM synthesis

Circle²’s oscillators can also be used for AM (amplitude modulation) synthesis, where one (or more) is simply used to modulate the output level. We use exactly the same setup as in the previous FM example, however the modulation circle of Oscillator 2 is this time dragged to modulate the Output level. Again, experiment with tuning levels and wave shapes - AM can have some really crazy results!

5. Synthesising drums

Let’s start with synthesising a kick - we simply use a sharp decaying envelope to control the pitch of an analog sine wave oscillator, and the frequency of the noise oscillator. Next we’ll synthesise a shaker loop using filtered white noise. Firstly, we turn on both the noise oscillator and the Arpeggiator (in sync mode at a 1/4 rate). Adjusting the frequency up, we turn on a bandpass filter. Finally, we assign a sequencer to modulate the filter frequency for added rhythm.
