The daily Schaaf 10: Breaking the rulez with modular synths

This example shows the most important aspect of working with modular synths – breaking the rulez. In standard synthesizers you have basicly three different groups of modules: sound generators, sound shapers and modulators. In most cases they are connected in a fixed routing configuration. At a modular system, the routing is completely free and noone stops you from using a modulator as a sound source or an oscillator as a modulation source. In this example, I fed a LFO and the Gate output of a step sequencer as the sound source into the RT-451 filter for a rhythmic structure. I recorded two different rhythms with different tempos (breaking the rules II) and I fed the RT-311 swarm oscillator into the RT-451 filter in the third recording. Instead of using a complete voice structure with ADSRs and VCAs I simply controlled the volume of the oscillator with a fader on my mixing desk. All three recording tracks are processed with the new EFFEXX multi effect module RT-1701.

In diesem Beispiel geht es um den wichtigsten Aspekt bei der Arbeit mit Modularsynthesizern: Dem Brechen von Regeln. Bei Synthesizern kann man die einzelnen klangbestimmenden Module in drei Hauptgruppen unterteilen: Klangquellen, Klangveränderer und Modulatoren. Ferner ist sind die Verbindungen zwischen diesen Elementen in der Regel weitgehend festgelegt. Bei einem modularen Synthesizer nimmt der Nutzer die Verbindungen zwischen den Modulen selbst vor und entscheidet unabhängig der eigentlichen Bestimmung darüber, in welcher der eben aufgeführten Gruppe das Modul bei einer Klangeinstellung eingesetzt wird. In dem Beispiel oben gibt es drei aufgenommene Spuren. Als Klangquellen kommt zum einen der Gate-Ausgang eines Step-Sequenzers, zum anderen der Ausgang eines LFOs und als letztes der Swarm Oscillator RT-311 als Klangquellen zum Einsatz. Alle drei Spuren gehen über das RT-451 Multimode Filter in das EFFEXX RT-1701 Effekt Modul.

The daily Schaaf 8: First experiments with the EFFEXX Multi FX engine

This is the first demo I created with the current beta version of the EFFEXX effect module. I am feeding a simple drum groove from the Spectralis into the EFFEXX module and destroy the sound of it. We hope that gives a first impression about the sonic capabilities of the new module. The EFFEXX module runs as a delay, reverb and filter on the drumgroove. You can listen to extreme feedback settings, serial configuration of delay, reverb and filter and a lot of realtime tweaking.

Heute habe ich eine erste Demo mit der gegenwärtigen Betaversion des EFFEXX Multieffekt-Modul produziert. Die Version ist noch recht abgespeckt – aber die neue Engine läuft nun und bis zur Superbooth 2017 wird es noch viele Änderungen und Ergänzungen geben. Ein einfacher Drumgroove wird in dieser Audiodemo mit dem Eurorack Modul zerstört. Man hört Delays mit extremen Feedback-Einstellungen, Hall und das Filter in Lowpass Betrieb.

 

Sound fart of the day 4: Fixed Filterbank vs. Noise and VCO


united-kingdom-flag-iconThe Spectralis 2 is the sound source and the strymon timeline the delay processor. I created a step sequencer pattern that controls the volumes of the fixed filterbank bandpass filters and fed noise and a single oscillator into the filterbank.

germany_textureDer Spectralis 2 dient als Soundquelle und das Strymon timeline Delay als Effektprozessor. Man hört wie sich die Lautstärkemodulation der einzelnen Filterbänder auf Rauschen und einen Oszillator auswirken.

 

Sound fart of the day 3: Big rooms in outer space


united-kingdom-flag-iconThis time I created some big spacey rooms for the Waldorf NW1 Wavetable Oscillator, the RT451 filter and the Doepfer A-155 step sequencer.  With all the different effects it’s more a space fart than a fart sound but who cares when it sounds like that. (I know, there is no sound in outer space at all.)

germany_textureDieses Mal habe ich den Waldorf NW1 Wavetable Oszillator, das Radikal RT-451 Multimode Filter und den Doepfer Eurorack Stepsequenzer A155 verwendet, um eine spacige Atmosphere zu schaffen. Dies gelang ausgerechnet über den Einsatz einiger Effektgeräte. Es ist seltsam, dass einem gerade begrenzte Räume mit Raumreflexionen und endlos langen Hallfahnen ein Empfinden von Weltraum vermitteln, obwohl dort nur eins herrscht – Stille.

RT-311 Swarm Oscillator description

DSP based multi oscillator module with parameter snapshot interpolation

The RT-311 offers two main oscillators with sweepable waveforms, oscillator synchronisation, TLM, linear FM and exponential FM. The RT-311 can store up to 8 memory setups with 8 snapshots each, holding all oscillator settings and memorizes them even after powering down your modular synth. One highlight of this module is the opportunity to interpolate between these parameter snaphots. Interpolation can be controlled with an external control voltage or with a built in LFO. The speed of the internal LFO can be controlled with an external control voltage as well. The interpolator has even an external output to interpolate one parameter of an attached module.
Both oscillators can built swarms of oscillator clones. Up to 16 Oscillators are running simultaneously at the highest setting. The detune knob changes the pitch of all oscillator clones between ultra slow oscillator frequency beating effects and multiple frequency drones and chords.
The swarm can be pitched in musical intervals, chords, clusters or fat detunes. The swarm tuning can be stored into the snapshots too. That allows for to built up to 8 different chords with different sound settings one can change while playing in a setup.
Both oscillator swarms have independent outputs. If one sets the exponential FM inputs depth to maximum, the inputs run with Volt per Octave scaling. The oscillator swarms can then be used like two independent Synth voices.
The scale inputs can also get quantized to musical scales. That makes it easy to control the swarm from a step sequencer. Just select the root key with the tune knob and a pentatonic scale and turn the knobs of your sequencer for always matching tonal sequences.

RT-311 demos – an growing list of sound examples

1.) RT-311 Subwoofer test

Does your subwoofer handle the low frequencies of this little snapshot interpolator demo? If not you should shop for something else.

The file can be downloaded here:

2.) Interpolating swarm clouds

The parameters of the RT-311 can be automated by interpolating between different snapshots of sound settings. There is even an interpolator data output for the control of additional modules. In this example the RT-451 Dual Filter module is connected to this output.

You are listening to waveform, pitch and TLM modulation, FM etc. changing continuously over time and you probably have never heard before that all these parameters are changing simultaneously.

The player above plays the mp3 version of the demo. You can download a uncompressed wav-file version here.

3.) More swarm oscillator chords

The oscillator swarm offers some chord presets, that can be used as tuning sets for the swarm. I fed the oscillator into the RT-451 dual multimode filter. The cutoff frequency is under control of an ADSR envelope. Finally I put a little delay onto the demo.

4.) Chord swarm 1

The oscillator swarm offers some chord presets, that can be used as tuning sets for the swarm. I fed the oscillator into the RT-451 dual multimode filter. The cutoff frequency is under control of an ADSR envelope.
Finally I put a little delay onto the demo.
You can listen to three different short clips.

The player above plays the mp3 version of the demo. You can download a uncompressed wav-file version here.

5.) Interpolating sequence.

In this example you are listening to the RT-311 Swarm Oscillator interpolating patch, triggered by a one bar beatstep sequence. The interpolator is controlled by the RT-311 internal LFO. The external cv output of the interpolator controls the RT-451 for additional filter effects. After some dry bars I added some reverb and delay for a more cosmic experience 😉

The player above plays the mp3 version of the demo. You can download a  uncompressed wav-file version here!

6.) Musical scales

In this example I am experimenting with the scale settings of the RT-311 swarm oscillator. The „swarm“ itself is not in use in this example – I am using the oscillators like two single oscillators. The LFO, that controls the pitch input, controls the cutoff frequency of the RT-451 multimode filter in the sawtooth section of this demo (starts at the half of the file). Setting the modulation depth of both filters in opposite direction creates this stereo animation.
At the end I am deactivating the scale quantizer so you can hear, what the oscillator would sound like without the quantizer.
I am using the tape delay setting of the soundcraft mtk mixer and feed the echo signal into the reverb fx of the second fx processor.

You can download the demo as a wav-file here!

7.) Oscillator sync experiments

In this demo you are listening to some live tweaking of an oscillator synchronisation patch. I fed the oscillator into the FXs of my mixing desk to create these sonic landscapes. The wav file can be downloaded here!

8.) RT-311 first demo


I created that demo with an early prototype of the swarm oscillator. I created a lot of different sounds together with our RT-451 filter, envelopes and VCAs from Doepfer etc.
