Korg PS 3200 - 10. Modulation Generator - 2 (MG-2)

Unlike the MG1, MG2 isn't internally patched.
So to use it , cables are needed.

It has just one waveform (triangle) , and one output jack.
Frequency ranges from 0.3Hz, to 10Hz.
Range : 5V PP
You can use it for PWM of the SGs or modulating the filters.
It could be the sampling frequency of the S/H.

Kits - Drums - Deluge

To change the volume of each individual row
eg to increase just the volume of your bass drum:
1. Press Audition
2. Press the volume button in your effects section
3. Turn the top gold knob.

note: make sure the effect entire button is not lit. Otherwise you will effect the entire
drum volume when you turn the gold knob. 

Korg PS 3200 - 8. Sample & Hold (S/H)

The S/H converts a input voltage into a stepped output voltage.
Every time it is triggered, it samples a new input voltage and spits out the old voltage.
This module is made up of a switch, a pot & 4 jacks.

The switch is used to sync the sample rate with the input signal.
If the input signal is cyclic, this switch will sync the sample rate with the input signal.
This will result in the stepped output repeating itself in regular intervals.
To get clocked random outputs, feed in noise (which is of course non-cyclic) .
To get un-clocked random outputs, feed in noise & turn Sync to off.

The Clock Frequency pot is a manual frequency adjustment device.

The Clock out is the signal from the S/H clock generator.
This is a S-trigger.

The S/H out converts input voltage signal to a stepped output voltage.

The two lower jacks allow you to input external trigger & sampling voltages.
The trigger needs to be a S-trigger (5v ?)
The Sample voltage can range between -5V & +5V.

 Above, is an example of a random note generator.

Korg PS 3200 - 3. Dynamic Low -Pass Filters (DLPF)

The Cutoff (Fc) & Peak are pretty standard.
The Peak emphasises resonance at the cut-off point.

The KBD filter balance:
This adjusts the Fc of each of the keys independent LP filters over a rising or falling slope corresponding to the scale of the keyboard.

Expand:
This adjusts the degree to which the EM  (envelope modifier) envelope signal affects the Fc.
The EM section is on the right of the filter. ... a standard ADSR.

MG1 or S/H modulation intensity
Like the one to the right which effects the SGs, this adjusts the depth of modulation from
MG1 & the S/h.

Korg Ps 3200 - 5. Equalizer (EQ)

The EQ has no voltage control.
It's made up of 7 octave bands.
They are used to control the tone colour of the whole sound... not each key.

The bands are 125, 250, 500, 1K, 2K,4K, 8K Hz.

Access Virus - Basic Intro

 

It looks complicated at first glance.

All those knobs.

The basic editing principle is however simple. 

Each section — oscillators, modulators, effects, filters and the centre control — has its own separate Edit button. 

This reminds me of the A6, Andromedia.

 

The sections from left to right are:

ARP

Matrix

Effects

Oscillators

Central control

Mixer

Filters

Envelopes - Filter

Envelopes - Amp 

It's a very versatile device.

Not just a synth.

It's a sound card & an effects processor.

TI stands for total integration. 

You can control it with the hardware knobs, or you can control it with a 

software plugin.

 You can run 16 voices, each with its own MIDI track , each with its own

separate effects. 

For example can play a bass track, a pad, a string line, etc at the same time.

 

Oscillators

There are 3 oscillators.

These are your primary sound sources: OSC1,2,3

You pick them with the "select" button.

Press this button repeatedly to move the focus of these knobs to the desired oscillator.

The Virus TI offers different oscillator types which you can combine

 to create complex sounds.

The top row of 4 knobs in the oscillator section are all assigned by the OSC1/2/3 SELECT button.

 

Press EDIT once to access parameters relevant to the selected oscillator.

You can now use the VALUE 1/2/3 knobs beneath the display to adjust the displayed parameters, and the PARAMETER buttons to navigate the pages within the menu

Korg PS 3200 - 4. Envelope Modifier (EM)

The PS3200 has lots of envelopes.
This can be very confusing at first.

The most obvious one to explore is the EM. This is directly to the right of the filter.
It's a combination of VCA & EG (envelope generator).
The VCA varies the volume of the sound coming from the filter.
It is voltage controlled by the ADSR .envelope.
The envelope is triggered whenever a key is pressed.
(on the keyboard).

There are also some external jacks.
So external controllers (like a PS-3040) ... for the attack.
or a RS-3040 for the release.
I think you can also use a S-type foot switch ???

tHESE  external S-triggers (for the release) start high (+5V & short to ground).
Moog & Yamaha also use such triggers.... worth experimenting.
The attack is interesting ... a -5V to +5V signal.
The overall VCA is controlled by a 0V to +5V signal.

Above these jacks is a modulation balance knob.
It appears that just like the SG & filter,   the MG-1 & S/H  can modulate this VCA.

A secondary function of the EM:
The EM  (envelope modifier) envelope signal also effects the Fc of the filter
This is an impt concept to grasp.
Because the ADSR envelope is tied to both the VCA and the filter, an EXPAND effect is produced.
The Expand knob is part of the filter section.
