OVERVIEW: This patch demonstrates how SCANNER can be used like a traditional waveshaper, creating a complex morphing tone using modulation from the LFO and an audio signal from OSC-1.

SCANNER: Alter the timbre of the waveshaping with the Z control. Emphasize the wavefolding with the X CV and adjust the timbre with the X control. Emphasize the modulation from the LFO with the Y CV; the Y control subtly changes the sound of the modulation.  Turn B scale clockwise to decrease the prominence of the waveshaping.

Unity: Not used.

SEQ-3: Row 1 controls pitch, gate sequence controls note-on. Individual step gates reset the LFO and jump SCANNER.

ADSR: Adjust the controls to change the shape of the amplitude contour of the sound.

LFO: Adjust FREQ to change the groove in the modulation of the timbre of the sound.

Top Scope: Monitor the main output of SCANNER.

MIDI: Not used.

OSC-1: Transpose the sequence with the FREQ control.

Mixer: Not used.

Delay: Experiment with different delay settings to color the sound.

Overview: This patch also showcases audio waveshaping, but with a more nontraditional timbre based on waveforms generated by physical processes. Take note of how a tremolo is applied to one of the scan input signals, creating timbral motion in the output tone.

SCANNER: Alter the overall timbre of the waveshaping effect with the Z control. Turn X CV counterclockwise to emphasize the droning tone. The X control alter the timbre of the drone. Turn Y CV counterclockwise to emphasize the tremolo'd tone. The Y control alters the timbre of the that sound. Adjust the B scale control to set the amount of amplitude modulation from the ADSR.

Unity: Not used.

SEQ-3: Row 1 sets the speed of the LFO per step.

ADSR: Adjust the controls to change the dynamics of the sound. The gate is controlled by the LFO square wave output.

LFO: Adjust FREQ to change the modulation of the timbre and amplitude of the scanner output.

Top Scope: Monitor the LFO and ADSR.

MIDI: Not used.

OSC-1: Set the pitch of the tone with FREQ.

Mixer: Set the levels of the main scanner out (Channel 1) and the filtered logic out (Channel 2).

VCF:  With Channel 2 Up on the mixer, set the brightness of the Scanner's Logic output (delta logic). 

Delay: Not used.

VCAs: The left VCA shapes the amplitude of the Y scan input according to the LFO. The right VCA provides volume control over the output.

Bottom Scope: Monitor the filtered logic output from SCANNER and the main output.

Overview: Here we introduce a new functionality, shaping a simple slow modulation source (the LFO) into a much more complex waveshape, creating complexity in the motion of the patch.

Note: Please excuse the audio dropout glitches in the video; those come from capture not the original patch.

SCANNER: Turn Z clockwise to increase the complexity of the modulation signal. A clockwise turn of X CV emphasizes the smoother modulation shape, Y CV emphasizes the stepped shape. The X and Y controls set the symmetry of the two waveshapers, subtly changing the modulation shape. Set the range of modulation with the A and B manual controls.

Unity: Not used.

SEQ-3:  The (very slow) LFO provides external clock, row 1 controls the shape of the scan surface.

ADSR: The envelope is triggered by the hemisphere logic output. Adjust the controls to change the modulation of the oscillator's pitch.

LFO: The LFO outputs are the scan signals, and the square clocks sequencer. Adjust FREQ to change the rate of modulation in the patch.

Top Scope: Monitor the output of the scanner and the hemisphere logic triggering the ADSR.

MIDI: Not used.

OSC-1: FM CV controls amount of modulation form ADSR, PWM CV controls amount of timbre modulation from scanner. FREQ sets the base pitch.

Mixer: Not used.

VCF: FREQ CV sets amount of filter cutoff modulation from Scanner, FREQ sets amount of VCO tone heard at output, RES emphasizes filter modulation.

Delay: Turn up mix and feedback to emphasize the pitch shifting echo effect.

VCAs: The left VCA can be used as a slider to set amount of delay time modulation. The right VCA is a volume slider for the sound.

Bottom Scope: Not used.

Overview: Another showcase of SCANNER's audio waveshaping abilities, this patch shows how the alternate outputs can be processed and fed back through the A or B inputs.

SCANNER: As is always the case when an audio source is patched into the X or Y inputs, the Z control sets the timbre of the waveshaping. X CV emphasizes the FM waveform waveshaper; Y CV the filtered square waveshaper. Like usual, the X and Y offset controls make subtle changes to the timbre of the respective waveshaping channels. Turn the B scale towards noon to mute the sound of the Delay patched through SCANNER.

Unity: Not used.

SEQ-3: The LFO provides external clock, the gate sequence triggers the ADSR, row 1 controls scanner shape, row 2 controls LFO frequency.

ADSR: The heavily modulated sequencer clock provides the gate. Adjust the controls to shape the amplitude of the sound.

LFO: The output modulates sequencer clock, and the frequency is modulated by the sequencer. Turn down FM 1 CV for a less chaotic sequence. Square is patched into scanner Jump.

Top Scope: Visualize the main and smooth surface outputs of SCANNER.

MIDI: Not used.

OSC-1: Change the pitch of the output with the FREQ knob, add chaotic noise with the FM CV knob.

Mixer: Not used.

VCF: Change the tone of the scanner output with the FREQ and FM CV knobs. Note that the filter is self oscillating to produce an audio tone; reducing RES will kill the sound.

Delay: Change the parameters to change the tone; the Time control has a pitch shifting effect.

VCAs: The right VCA applies the envelope to the amplitude of the sound.

Bottom Scope: Not used.

Overview: One more look at audio waveshaping possibilities, this patch shows how the Steppes basis functions create a bitcrushing effect.

SCANNER: A clockwise turn of Z eases back the bitcrushing on the sound; turning X CV and Y CV clockwise increases the wavefolding sound. The X and Y controls further shape the timbre of the sound. Turning B scale clockwise reduces the bitcrushing effect.

Overview: Finally, this patch shows how SCANNER can create a modulatable stepped sequence.

SCANNER: Use the Z control to adjust the base sequence shape (which is modulated by SEQ-3). Emphasize the slower notes with X CV and the double time notes with Y CV. The X and Y offset controls subtly affect the sequence shapes by changing the symmetry of the scan. The A and B controls can be used to set the scale of the sequence at the output.

Unity: Not used.

Top Scope: Monitor the ADSR gate input and the scanner output.

MIDI: Not used.

OSC-1: Transpose the sound with the FREQ knob.

Mixer: Not used.

VCF: Adjust the timbre of the sound with the FREQ knob, adjust the amount of envelope modulation with FREQ CV.

Delay: The gate out from the sequencer controls the delay time causing a pitch shift and change in timbre. Adjust this effect with the controls.

Bottom Scope: Not used.
