| Introduction |
| Zephod CSynth is a polyphonic
analog modeling 16-track synthesizer made to be used as a buzz generator.
It uses a lot of CPU, but has great features like two LFOs and two envelopes,
so you can modulate things like an oscillator´s phase distortion
or the cutoff frequency (from -100% to +100%) |
| |
| Zephod CSynth has
53 global parameters and 2 track parameters. Because of the
huge amount of the parameters, you will need a high resolution screen (like
1280x1024) to see all the machine´s parameters (buzz doesn´t
has a vertical scroll for machines yet :) |
| |
| You
can also load the GUI, righ clicking the machine in Machine
View and selecting Edit |
| |
| How
does it work |
| Zephod CSynth is based
on substractive synthesis. This kind of synthesis "substracts" harmonics
to a tone. A VCF (Voltage Controlled Filter) is used to do this.
Zephod CSynth can produce 4 types of waveforms |
| |
|
Sine
|
This kind of waveform
only has one harmonic. Its frequency is the same as the note played and
is used to play smooth tones, such as flutes, bass sounds, etc. |
|
Sawtooth
|
This waveform is very
rich in harmonics and the VCF can affect it drastically. This waveform
is the most common for synthetic sounds. |
|
Pulse
|
On this kind of waveform,
the Phase Distotion (PD) can get more dynamic sounds or more character
if its modulated. |
|
Random
|
Generates White Noise.
It´s used with VCF and Envelopes to get percussive sounds or the
classic "wind effect" with a low-pass filter |

|
| Oscillators |
| There are
3 oscillators in Zephod CSynth |
| |
|
Main
(OSC1)
|
Base oscillator |
|
Secondary
(OSC2)
|
It has the same tone
as the first oscillator, but you can detune it thru the parameters (OSC2
tune and OSC2 finetune) to get a richer sound |
|
SubOscillator
|
This oscillator is one
octave detuned with the OSC1. Its used to get fatness to the sound |
| |
| VCF
(Voltage Controlled Filter) |
| The Voltage Controlled
Filter is the part wich gives the analog feel to the sound. It subtracs
harmonics to the output produced in the oscillators. There are three types
of VCF |
| |
|
Low
Pass
|
substract harmonics behind
the cutoff frequency |
|
Hi Pass
|
substract harmonics below
the cutoff frequency |
|
Off
|
Deactivates the VCF |
| |
| Q
Control (Resonance) |
| Q is the cutoff filter´s
banwidth attenuation. This gives a fatter sound. Setting Q to the maximum
value gives autooscillation. |
| |
| Envelopes |
| Zephod CSynth has two
ADSR (attack, decay, sustain and release) envelopes, wich can be
assigned to almost every parameter. |
| Normally it is used with
Volume or VCF |
| |
| LFOs |
| The Low
Frequency Oscillators are used to modulate parameters as the cuttoff
frequency, oscillator´s tone (vibrato), pulse width, etc |
| All the LFO
values (OSC's PW, PITCH, AMPL, VCF Q, VCF CUTOFF, etc) goes from
-100% to 100% (where -100% = negative polarity) |
| |
| Importing
.nti presets |
| Zephod CSynth
can import .nti files (Noisetrekker´ Csynth presets) |
| To
import them, right click the machine in Machine View and selecting
Import *.nti |
| The
import *.nti is available on the GUI too |
