"You could say this patch is dedicated to Klaus Schulze. And since this patch has (in my opinion) some elements from music of the early days of Schulzes work, I called it Schulzator" - Matthias Klag.

This is one of many of the excellent new patches released for the Modular II with version 2.01 of Pulsar.

It is named after Klaus Schulze, one time drummer with Tangerine Dream, and reknowned synthesist/electronic musician. Read about him at his web page here.

 

The patch uses a single Oscillator, but uses many other modules to offer many different modulation options. If you look at the Signal Flow diagram for the Schulzator, you’ll see that there is a single sound source, the Uknow Osc and if you follow the line down the middle, there’s a fairly straightforward path from the Oscillator, through the Vocal and MultiMode filters, a VCA and then a through a chain of effects (Delay, Compressor, Phaser).

 

What gives the patch its interest is the huge number of modulation possibilities. You can see from the signal flow that there are 5 different LFO’s and two envelopes which can modulate the sounds in different ways.

Three of these LFO’s can have their amplitudes controlled by the output of the Frequency Divider, which is being fed a signal from the Constant Frequency Module. The Frequency divider means that these LFO’s can all have their Amplitudes set to separate divisions of the same frequency, so it is possible to set the LFO’s oscillating in interesting rhythmic patterns (ie, one LFO at 3x the speed of the other, etc.)

Thus, for example, you can set the Resonance of the MultiMode filter to be modulated by the Pulse LFO at a certain speed and the Frequency of the MultiMode filter to be modulated by the Multi LFO running at an exact division of that speed. You can, of course, switch off the external control of the LFO’s and set the amplitudes at unrelated speeds. The use of the Multi LFO’s means that you can also have two different wave shapes (Square, Saw, etc) modulating the filters at the same speeds.

 

The modulation connections are as follows:

 

PwmA (Pulse Width Modulation) of the Uknow OSC is modulated by the output of Sine LFO (1).

 

PP (Phase of the Pulse Wave) & SP (Phase of the Sawtooth Wave) of the Uknow OSC is modulated by output of Sine LFO (2).

 

Pmod1 (Modulation depth) of pitchModifierB is modified by the output of MW Triangle.

 

VPM1 of Vocal Filter is modulated by the output of Multi LFO B (1). ( The Vocal filter is not in the first release of the manual, but this is probably the Pulse Width modulation input for the filter.)

 

ResM (Depth of the Resonance modulation) of multiModefilter A is modulated by Output of Multi LFO B (1).

 

VPM2 of Vocal Filter is modulated by the output of Multi LFO B (2) (Probably the another Pulse Width modulation input for the filter.)

 

CFm2 (depth of the second cutoff frequency modulation signal ) of multiMode filter A  is modulated by the output of pulseLFO.

 

Lmod (controls the intensity of the modulation of all levels by the modulation signal ) of ADSR Vintage 1 is modulated by the velocity of MVC A.

 

Fm of Vocal Filter (Probably Frequency (or Formant?)) & CFM1 (depth of the first cutoff frequency modulation signal) of Multi Mode filter A modulated by output of ADSR Vintage (2)

 

The envelope ADSR (1) modifies Lin VCA (determines how much the control signal at the modulation input controls the level of the audio signal at the output.)

 

The envelope ADSR (2) modifies CFM1 (depth of the first cutoff frequency modulation signal.) of multi Mode filter A and VPM2 of Vocal Filter (see above). As the Envelope is triggered by the gate this means that the Filter will effectively open (according to the envelope settings) when a note on the keyboard is played.
