The 0-COAST is a single voice patchable synthesizer. It’s name re ects the fact that it utilizes techniques from both the Moog and Buchla paradigms (aka “East Coast, ” and “West Coast, ” due to their locations), but is loyal to neither and thus implements “no coast synthesis.
For example: As you may have guessed, this is instructing you to patch the Square Wave Output ftom the 0-Coast’s Oscillator Circuit to the External Input of the Balance Circuit. Don’t worry if it sounds daunting, you’ll quickly get the hang of it. Accompanying the written patch instructions, you’ll also nd small, visual representations of the connections.
(white) knobs are used to Attenuate (i.e. “scale”) and/or Invert incoming CV. Jacks: Illuminated Buttons and Activity Windows: Every jack in the 0-Coast is either an input or an output. The 0-Coast utilizes Buttons for certain functions and behaviors and <light> Jacks are patched together with cables. Simply plug one end or <...
0-COAST (Figure 10). The signals inside the 0-COAST are much higher strength than typical instrument or line-level audio signals. We call these signals “Modular Level. ” For example, the OSCILLATOR Triangle OUT is a Modular Level output that has an amplitude of about 10 volts peak-to-peak, which is over 4 times “hotter”...
For MIDI control, use the included MIDI Adapter to plug your MIDI controller or sequencer to the MIDI Input on the 0-COAST (Figure 13). The 0-COAST defaults to receiving MIDI on ALL Channels, so you should be able to strike any key or start a sequence on your MIDI controller and see the MIDI Activity window <...
They can be con gured to react in various ways to MIDI data. For example, the CV OUTput can be assigned to velocity, note number, mod wheel, et al. The 0-Coast also has a fun arpeggiator with two modes, an additional LFO at the MIDI B outputs, and the ability to switch between Legato and ReTrigger playing styles.

MIDI A circuit and the OSCILLATOR circuit allows for playing the Figure 18: PITCH of the 0-COAST from a MIDI controller. To hear this, rst, set 0-COAST to MIDI A CV: Normalizations the “Default Sound” (Figure 8) and then patch your MIDI controller as in Figure 14, and then play some keys or send a sequence from your MIDI controller.
Gate IN and DYNAMICS CV INput Jacks, the CONTOUR Signal OUT is wired to modulate DYNAMICS. In order to hear this, set 0-COAST to the “Default Sound” (Figure 8, Page 8) and play some keys or send a sequence from your MIDI controller. It is possible to re-route this wire by patching to the CONTOUR Gate IN.
(Figure 23). “Gate Low” is 0V (or no signal at all). There are a lot of similarities between these signal types. Keep in mind, the 0-Coast responds to like signals in similar ways. A Gate; however, is longer, anywhere from a few milliseconds to “always on. ” The length of the Gate (in time) is referred to as the Gate’s Width.
Depth of Modulation to its them with related signals, or when inverting respective parameter (more on that later) For them multiple times per cycle (see Make Noise CV Input Attenuators, such as OVERTONE, zero modDemix, “Ring Modulation. ” ) amplitude is at full counterclockwise, resulting in no modulation regardless of the signal input.
Attenuversion An example user for the Attenuverter on the Control Processor’s CH.2 INput is patching a variable depth Vibrato. If you patch a Cycling SLOPE directly to the 1V/Oct input on the Oscillator, you get a vibrato, but with a range of many octaves. Instead, try patching it to the right input of the Control Processor, take either output to 1V/oct, and adjust the Depth using the CH.
Using a unipolar Control Voltage like from SLOPE, it is possible to control the range and direction of modulation, in relation to the 0-Coast’s Panel Control setting, simply by adjusting the position of the associated INput Attenuvertors. For example, using the SLOPE normalization to the MULTIPLY CV INput, this has the e ect of manually rotating the Multiply Panel Control knob over time, starting with the initial Panel Control setting shown below.
Oscillator Set 0-COAST to the “Default Sound” (Figure 8, Page 8). To hear how the OSCILLATOR works, it is helpful to either hold a key down on your controller, or to set the 0-COAST to Drone, as shown in Figure 9.
CW, so that you are only hearing the Overtones. Hold a key on your controller or set the 0-COAST to Drone (refer to Figure 9, Page 8). Slowly turn the OVERTONE Panel Control Clockwise and listen for the change in the timbre of the sound as the single Overtone fades from ODD to...
MULTIPLY CV Attenuator and Panel Controls alters the way the timbre of the 0-COAST is modulated. The CV Attenuvertor is capable of adding and subtracting from the Panel Control with the “OFF” point being at 12 o’ Clock. The SLOPE and...
OSCILLATOR Core and are thus referred to as Overtones. To hear how the BALANCE works, rst, either hold a key down on your controller, or to set the 0-COAST to Default Drone as shown in Figure 9, Page 8.
East Coast instruments and perhaps even Far East Coast instruments :) This combination of West Coast technique and East Coast circuitry is 0-Coast synthesis at its nest, allowing the Low Pass Gate to be used in tandem with an extremely-important East-Coast synthesis circuit: the 4-stage Envelope we call CONTOUR.

DYNAMICS circuit, resulting in amplitude envelopes which greatly de ne the sound of the 0-COAST. This approach takes inspiration from the original Loudness Contour circuit of the MiniMoog, which is perhaps the most well-known and heavily-used example of East Coast Synthesis.

Clockwise in order to be more Exponential increases the rate, causing the 0-COAST to sound Figure 54: more percussive. Setting it to be more LINEAR decreases the rate, causing the 0-COAST to fade in and out of existence. EXPONENTIAL LINEAR...

10V peak to peak, which is more then 3 times the strength of the typical line-level audio signal commonly used in the studio and on stage. The DYNMC OUT should only be used when interfacing the 0-COAST with instruments capable of handling the large voltages produced by this type of output, such as modular synthesizers.
In the next section we will go into the inputs and outputs that are not normaled or hardwired, using patch cables to expand the number of connections between the circuits on the 0-Coast. This will allow for greater depth and complexity of sound.
Looking over the faceplate of the Using Random Out to Modulate OVERTONE: [TAP] PGM_B to change rate. 0-Coast, we will see a number of patch points that are not connected by gold wire to any others. To begin, set up the Default Sound Drone (Figure 9).

(CONT'd) This section contains short descriptions and examples for all the connections that are not part of the gold wire signal ow of the 0-Coast. Connecting cables to these patch points has the potential to expand the capabilities of the 0-Coast, without changing anything about its default operation.

DYNAMICS Out: This output contains the same signal as the Line Out, but at full amplitude for connection to modular synthesizers or back into an input of the 0-Coast for feedback. It is NOT recommended to patch this output to line level...
The "Open Connections" section showed the many places in which it is possible to expand your use of the 0-Coast without changing anything about its Normal operation. In this section we will show patch connections with the potential to override that operation entirely.
Patching into a jack to override a normalization does a lot to open up the signal ow possibilities in the 0-Coast. The concepts already outlined can get you very far, but as you continue patching, some questions will eventually start to arise: What if you...
