Make Noise 0-Coast - Basic Notes

Since my recent purchase of a 0-Control, I've been falling back in love with the 0-Coast and all things Make-Noise. These are some basic revision 0-Coast notes

The O-Coast can be divided into 7 parts or modules.
If you look at the synth this way, and study the internal wiring it's not as intimidating as it first looks.
The basic modules are:
1. Midi to CV
2. Utilities
3. VCO
4. Sound Processor (waveshaper)
5. Envelope 1 (Slope).. AD
6. Envelope 2 (Contour)... ASD
7. VCA - Mixer / LPG
It's a excellent example of the bare minimum of modules needed to make a "complete instrument".
Personally, I feel it's more West Coast than East. The lack of a dedicated filter
(apart from the LPG) and the extensive use of wave-shaping remind me of a Buchla Easel.


Though the 0-Coast has just one oscillator, the 1st EG (Slope) can be cycled at audio rates, and can be thus used like a Modulation Oscillator.
The recent addition by Makenoise of the 0-Control makes it even more Buchlaish.

 1. Midi to CV
    Plug your midi sequencer/ DAW here
    It will convert Midi / CC data into control voltages & gates
    It also has an arpeggiator & LFO

2. Utilities
     The upper half has a Clock, Clock divider, S&H & Random voltages (Source of Uncertainity)
     The lower half is the CV processor section comprising things like a
     Mixer, Attenuverter, Inverter & Mults

3. VCO
    Basic oscillator with triangle & square waves.
    Both waveforms are internally pre-routed to the waveshaper/sound processor, but the triangle
    is also routed to the Mixer/LPG (you can break this connection with a jack).
    This module also has linear FM control & a 1V/Oct socket.
    The 1V/Oct socket is where you'd most commonly plug the pitch out from
    your Keyboard/sequencer.
    
4. Sound Processor
    This adds harmonics to make the sounds from the oscillator more complex.
    It can be though of as a timbre module that processors sound in two stages
    a. Overtone Stage
        This mixes 3 waveforms - the two oscillator waves & the slope EG.
        It adds sound that is higher in frequency, yet still harmonically-related to
        the Fundamental.
       !! is where the slope is blended into the audio signal path.
    b. Multiply Stage
        This takes the output of the Overtone Stage & multiplies it, .... this creates additional
       overtones & adds harmonics. This is the opposite of what happens in a LPF.
  
5. Envelope 1... AD "slope". 
     It has Attack / Decay stages and can me made to self cycle.
     This EG is routed by default to change the harmonics of the VCO
     It's internally connected to both the overtone & multiplier sections.
     The EG1 output can also be patched to other modules such as the Linear input of the VCO.
     (it would thus act like the Buchla Mod Osc).

6. Envelope 2 --- ASD "contour"
     This EG is routed by default to change the VCA
     It acts like an ADSR even though it only has a Decay pot -- this seems to represent both
     Decay & Release.
     The Gate input is where you'd most commonly plug the gate out of your keyboard/ sequencer.

7. VCA - Mixer / LPG
   This mixes the outputs of the triangle wave Oscillator with the Sound Processor
   (Overtone & Multply)
   The LPG is a combination of a VCA + low pass filter. (Very Buchla)
