Chapter 9: Signal Controllers | Clocks, CV, TRIG, SEQ, TRACKER, ARPEGGIATOR

⚛ A melody is a pre-programmed or improvised algorithm.

⚛ Additional Information

⚛ The following is a transcript of the narration:

✸ Signal Generators: VCO and LFO

✸ A VCO is a Voltage Controlled Oscillator. 

✸ The oscillator, in it's simplest form, generates periodically repeating waveform of user defined frequency and user selectable shapes.

✸ This gives the audio the sensation of a single note.. 

✸ LFO normally oscillates at frequencies well below the audio range.

Patch 7 Trigger

⚛ The following is a transcript of the narration:

✸ Patch 7 Trigger

✸ Send Trigger output 1 to Gate input of the Envelope to trigger it.

✸ Connect Triangle wave output of VCO 2 to VCA audio input 1.

✸ Output of the Envelope connect to CV input of the VCA.

✸ Send the control voltage and audio signal in.

✸ Adjust the tune of the VCO and parameters of the Envelope, and notice that the continuous tone transformed into a kick.

Patch 8 Sequencer

⚛ The following is a transcript of the narration:

✸ Patch 8 Sequencer

✸ Send Trigger 1 output to the splitter and feed both the Envelope Gate input and Clock-in input of the Sequencer. 

✸ Output of the sequencer send to 1 V / Octave input of the VCO 2.

✸ Triangle wave output connect to VCA audio input 1.

✸ Output of the Envelope send to VCA CV input.

✸ Open Signal and Control Voltage inputs.

✸ Adjust the envelope and sequencer steps until you hear a simple melody.

Patch 9 Arpeggiator

⚛ The following is a transcript of the narration:

✸ Set VCO 1 to LFO mode and connect the output to a splitter. 

✸ Feed Arpeggiator trigger input and Gate input of the Envelope with the LFO.

✸ Output of the Arpeggiator connect to 1 V / Oct Input of the VCO 2.

✸ Send Triangle wave output to VCA Audio input 1.

✸ Open Signal in and Gain.

✸ Output of the Envelope Generator connect to CV input 1.

✸ Open the CV in and close Gain of the VCA.

✸ Choose Chord, Mode on the Arpeggiator and adjust Envelope parameters to make the melody clearer.

✸ Changing rate of the LFO affects playback speed. 

Bonus Patch

⚛ The following is a transcript of the narration:

✸ Bonus Patch

✸ Starting from previous patch, take the triangle wave output and send it to VCF audio input. 

✸ Connect VCF Low Pass Output to VCA Audio input 1.

✸ Second output of the Envelope send to Resonance CV input of the VCF.

✸ Open the Cut Off, Reso CV input and Resonance on the VCF.

✸ Playing with time range of the Envelope and Cut Off of the VCF results in change of timbre and dynamics. 

✸ Feed Cut Off CV input with LFO.

✸ Notice variety of sounds you can generate with that patch.
