SECRETS OF THE DUAL DEFECT PROCESSOR MODEL 289


UPPER SECTION 

1 - multitriangle-core oscillator
left in - AM
right in - FM
control pot 1 - Pitch
control pot 2 - Wavemorphing
control pot 3 - Wavefolding
left out - main signal
right out - sub osc signal (1 octave below)
thus the regeneration pots give us internal AM and FM respectively (this is true for most of our osc models, just notice for the future)
also there's general advise to keep timebase at max (also true for all oscillators of ours)
balances should be apparently at their maximums too.



2 - classic fm oscillator
left in - AM to Carrier
right in - FM to Modulator
control pot 1 - Carrier Pitch
control pot 2 - Modulator Bias (about +/- 1 octave)
control pot 3 - FM Index
left out - FM'ed Signal
right out - Carrier Signal
left regeneration adds AM from main signal to Carrier, right one does FM from unFM'ed Carrier to Modulator


3 - Karminus-Weak Percussive Generator
left in - FM to Memory Position
right in - External Trigger or Burst Signal (from Burst Assistant program)
control pot 1 - Memory size
control pot 2 - LP Filter
control pot 3 - OSC Frequency
left out - OSC output (for Regeneration)
right out - Signal
one should use the right output only, since the left one is just auxiliary output for FM (left Regeneration pot)
better keep right Balance at min
Timebase pot does a lot!
notice! this is the second order system so it needs some external exciter (simple buchla trigger does the job, but feel free to experiment)
right Regeneration increasing will cause continuous excitation


4 - bit crusher/sonic decimator
left in - to Bit Crusher
right in - to Decimator
control pot 1 - Bit Count
control pot 2 - Sample Rate
control pot 3 - Simple Exponential Filter (to both channels)
left out - Bit Crushed signal
right out - Decimated signal
this is simple stuff
tweak Timebase


5 - filtor
left in - Signal
right in - Signal
control pot 1 - Cutoff
control pot 2 - LP Digital Resonance
control pot 3 - HP Digital Resonance
left out - LP Signal
right out - HP Signal
Regeneration pots bring analogue resonance to the signal path
Timebase is essential


6 - plate reverb
simple stereo algorithm with size, density and high frequencies roll-off separately adjustable
the main suggestion is to keep Timebase in the middle or even less - the sound becomes very dense and beautiful


7 - yu-verb
left in - Signal
control pot 1 - Size
control pot 2 - Decay
control pot 3 - HF Roll-Off
different stereo reflection model, the input is mono, produces really lush sound
set Timebase pot closer to the left extreme


8 - phase-ring
left in - Signal
control pot 1 - Swirl Rate
control pot 2 - Intensity
control pot 3 - Ring Feeding Amplitude
left out - Main Signal
right out - Swirl LFO
this is a phaser with trick - there's a soft ring-mod somewhere in the internal signal path
left Regeneration increasing will result in an analogue resonance of the all-pass-filter set
internal LFO goes also to the right output

________________________________________________________
LOWER SECTION

1 - ring modulator
left in - Carrier
right in - Modulator
control pot 1 - Ring < NoFX > Inv.Ring
control pot 2 - Internal OSC Freq
control pot 3 - Simple Exponential Filter (both channels)
left out - Carrier*Modulator
right out - OSC*Modulator
pot 1 is sort of central detent, to the left it adds modulator to carrier, to the right subtracts it
you have the ability to get externally modulated signal on the the left output and the one multiplied by internal osc on the right output, simultaneously


2 - frequency shifter
left in - Signal
right in - FM to Internal OSC
control pot 1 - Internal OSC Frequency
control pot 2 - Downshifted signal Level
control pot 3 - Upshifted signal Level
left out - Down Shift
right out - Up Shift


3 - harmonizer
left in - Signal to Down-shifter
right in - Signal to Up-shifter
control pot 1 - Down Shift
control pot 2 - Up Shift
control pot 3 - Simple Exponential Filter (both channels)
left out - Down-shifted
right out - Up-shifted
it's possible to construct the chord in this program


4 - frequency2CV converter/synthesizer (saw core)
left in - to Converter/Synthesizer
right in - to Delay Memory
control pot 1 - Amplifier for Left In
control pot 2 - Self-Modulation (AM+Delay Buffer)
control pot 3 - WaveFolder
left out - Synth
right out - CV
this is sort of converter/resynthesizer based on saw-core frequency controllable oscillator with wavefolding capability
one might use both inputs simultaneously


5 - 2-tap proportional delay
left in - to Division 1
right in - to Division 2
control pot 1 - Memory Divisor position
control pot 2 - Simple Exponential Filter for Division 1
control pot 13 - Simple Exponential Filter for Division 2
left out - Division 1
right out - Division 2


6 - smart looper 2
left in - Signal
right in - Signal to Overdubbing
control pot 1 - Sensitivity Trigger Threshold (right extreme allows overdubbing from right in)
control pot 2 - Buffer Modulator 1
control pot 3 - Buffer Modulator 2
left out - Buffer 1 content
right out - Buffer 2 content
both Regeneration controls at min


7 - trapezoid vca
left in - Signal
right in - External Trigger
control pot 1 - Attack Time
control pot 2 - On Time
control pot 3 - Decay Time
left out - Signal
right out - Trapezoid CV
Timebase helps to extend segments time


8 - psychorus
left in - Signal
right in -
pot1 - LFO Frequency
pot2 - Drifting
pot3 - Global Modulation
left out - Signal 1
right out - Signal 2
Timebase extends range of the LFO and audio frequency
