Superbooth 22: Radikal - Meet The Gang

video upload by sonicstate

"Radikal Technologies, weren't showing anything new, but did have the whole gang out to play, the Delta CEP A - which has the most delicious sounding digital filter, the RT-1701 MultiFX Module, the RT1936 - Guitar Processor and the RT-311 Swarm Oscillator

Georg Schaaf, the main man behind these was on hand to play with them and we enjoyed the results. We hope you do too."

Adding the RT-311 Swarm Oscillator to the DELTA CEP A sound engine!

video by Jörg Schaaf

'I describe in detail how the communication between the DELTA CEP and the Swarm Oscillator RT-311get established. After the connection and setup, the RT-311 follows the notes one plays via MIDI with the DELTA CEP A. That means, in paraphonic mode, the RT-311 plays chords instead of multiple oscillators with equal pitch."

DELTA CEP A - Workshop Audio-Demos, no talking.

Jörg Schaaf

"This video covers all the audio demos of the DELTA CEP A workshop introduction video but does not contain any talking. Please check the Delta CEP A workshop video if you would like to know, how the audio demos have been created. All what you hear in this video is made just with the Delta CEP A and it's built in FX section. Only the FM example uses the signal from a RT-311 swarm oscillator as a FM modulator.

The Delta CEP A simply has extremely clear waveforms with overtones up to the Nyquist frequency. For this reason, here is a link to the uncompressed wave file with the audio samples that the encoder did not want to process properly. The unfiltered Swarm oscillator signals were particularly affected. In the analyzer of the Logic Pro X EQ you can very nicely observe how far the overtones in the DELTA CEP A range for rectangular, pulse and sawtooth waveforms."

Radikal Technologies Delta CEP A - Workshop @SchneidersLaden

Published on Apr 2, 2020 SchneidersLaden

"Jörg Schaaf aka Radikal Technologies was in Berlin to present his latest synthesizer designs like the Delta Cep A. He is responsible for some modern classic synth designs made in Germany – like the Spectralis and Accelerator. In the past years he mainly developed eurorack modules like the RT-311 Swarm Oscillator, RT-451 Dual Filter, RT-1701 Effexx or the semi-modular synthesizer Delta Cep A which is also availabe as a desktop version.

His complex designs always bring a lot of functionality to the table and they can sound amazing."

One step at a time...

Jörg Schaaf of Radikal Technologies.

"In this little sequencer example I am using the pitch quantizer of the Delta CEP A and the Swarm oscillator to modify multiple sequences just by changing the scaling of the sequencer control voltages. As I selected the same pentatonic scale for both quantizers, the resulting sequences always match and create endless variations.

I am playing a little bit on the Spectralis hybrid synth from time to time. But it I apologize that this live playing sometimes sound like I am drunken or falling asleep. I can promise that that was not the case. I just forgot to activate the realtime quantize function of my right thumb and pinky ;-)

The sequences are running over the Delta CEP A delay and the Spectralis over a Strymon Timeline.
I am using both RT-311 outputs. One is fed into the external input of the Delta CEP A and the other output is fed through the RT-451 filter into a separate VCA with an independent envelope. The output of the VCA is then fed into the direct FX input of the Delta Cep A."

"Little demo featuring the synced delay feature of the new EFFEXX firmware version...
Audio Path:
RT-311 Swarm Oscillator - RT-451 Filter- A-132 VCA-EFFEXX Multi FX
Control:
LFO-A-155 Stepsequencer-Trigger 1 - Envelopes,
Trigger 2 - EFFEX Delay Sync
EG1 - Filter Cutoff Control
EG2 - VCA Level Control

EFFEXX Settings:
FX-1 = Tempo Delay
FX-2 = Chorus
Shift + Tempo. Max Tempo sets Delay in Sync Mode.
Received Gate signals are only the time base in quarter notes. The tempo of both delays are dependent from that clock but can be set to different note values."

Modular Ambient Chords

Published on May 30, 2017 Jörg Schaaf

Jörg Schaaf is the man behind Radikal Technologies.

"Modular Ambient Chords
I created a patch with the following modules: A-155 sequencer, A-147-2 VCDLFO, A-140 ADSR, RT-311 Swarm Oscillator, RT-451 Dual Multimode Filter and the RT-1701 'EFFEXX' Multi FX processor. I was so surprised by these floating ambient tones that I forgot to check the ISO settings of my DSLR camera. As a result, I received a noisy video footage. It really looked bad. So I decided to replace that footage with some Landschaftspark clips - which are not really much better. Anyway. It's all about that modular patch. So just close your eyes and listen to the modular ambient patch.
What the patch does: I have two audio signal sources. One audio signal is the output of the envelope generator and one signal is a chord from the swarm oscillator. These signals are fed into the inputs of the RT-451 Multimode filter. The outputs of the filter are fed into the EFFEXX Multi FX unit. The envelope signal source is triggered by the LFO. The LFO also triggers the step sequencer. The control voltages of the step sequencer control the cutoff frequency of both filters, the delay tuning of the EFFEXX string filter and the pitch of the swarm oscillator. I am changing the following parameters during the performance:
The reverb level.
The string filter frequency.
The modulation depth and speed of the string filter delay time.
The delay feedback.
The cutoff frequencies of the multimode filter.
The speed of the LFO.
I hope, you enjoy this litte ambient track."

"Radikal Technologies releases radical Eurorack-compatible oscillator module with a DSP-driven difference

MÜNCHEN, GERMANY: having turned heads, opened ears, and blown musical minds with a successful showcase at The 2017 NAMM Show, January 19-22 in Anaheim, California, high-quality synthesizer developer Radikal Technologies is proud to announce availability of its RT-311 SWARM OSCILLATOR — an advanced DSP-driven Eurorack-compatible oscillator module that, as implied by name, goes far beyond the realms of standard oscillator fare, firstly thanks to two oscillators that can both build swarms of (up to eight) oscillator ‘clones’ capable of being pitched in musical intervals, chords, clusters, or fat detunes, dutifully backed by having all parameter settings saveable as interpolatable snapshots, enabling even more radical results — as of March 28...

A dictionary definition of swarm typically reads: a large number of things... or oscillators, in the case of Radikal Technologies’ radical RT-311 SWARM OSCILLATOR, which, when switched to its highest SWARM setting, sees a maximum of 16 oscillator ‘clones’ running simultaneously. Something that stands out from the sound of the (ever-expanding Eurorack modular) crowd — to (partially) paraphrase the early-Eighties British breakthrough hit from synth-pop pioneers The Human League (themselves no strangers to the small-format modular system popularised by fellow German developers Doepfer Musikelektronik) — and surely something to behold? But building swarms of oscillator clones using both (OSCILLATOR 1 and OSCILLATOR 2) banks’ specialised set of TUNE, OCTAVES, DENSITY, SPREAD, and DETUNE controls to create pitched musical intervals, chords, clusters, or fat detunes does not necessarily mean that all 16 of those clones have to sound simultaneously.

Switched into (its default startup) Manual-Mode of operation, the RT-311 SWARM OSCILLATOR can function much like any other Eurorack-compatible all-analogue oscillator out there with OSCILLATOR 1 and OSCILLATOR 2 respectively appearing at the two (OUT 1 and OUT 2) outputs as sound sources for further manipulation elsewhere — using Radikal Technologies’ own RT-451 DUAL MULTIMODE FILTER module, for instance. In this scenario, the sound of the RT-311 SWARM OSCILLATOR module matches exactly what would be expected from the potentiometer-controlled parameter positions on its 32 HP (Horizontal Pitch) sized front panel; putting yet more controls at adventurous users’ fingertips, both banks of oscillators feature WAVE controls for smooth transitions between waveforms and TLM (Timelinearity Modulation), a variation of pulse-width modulation — known from Radikal Technologies’ SPECTRALIS 2 ANALOG SYNTHESIZER/ BEATMATRIX/FILTERBANK desktop hybrid — that can be applied to all waveforms, while exponential FM (Frequency Modulation) and linear FM modulation or PM (Phase Modulation) are also available alongside oscillator synchronisation. Pitch is, of course, controlled by the (calibrated) 1V/OCT input (which can be quantised so that only pitches of a certain tone sequence or scale are output).

Other operational modes make more radical results really shine through, though. Switching Snapshot-Mode into play permits the RT-311 SWARM OSCILLATOR to store up to eight memory setups, each with eight snapshots, saving all oscillator settings and memorising them even after whatever Eurorack small-format modular synth system is playing host to the module has been powered down! Such snapshots are assigned to one of eight positions accessible via the ‘big knob’ dominating the RT-311 SWARM OSCILLATOR’s front panel. Put it into Interpolator-Mode and everything (literally) revolves around the cyclic traversal of those snapshots, smoothly crossfading from one to the next with transitions taken care of via voltage control, an internal LFO (Low Frequency Oscillator), or the big knob itself — either way, the surrounding eight LEDs (Light Emitting Diodes) illuminate accordingly in user-chosen colours, helpfully highlighting which snapshot is playing at any given time.

To make room for an RT-311 SWARM OSCILLATOR in any Eurorack small-format modular system means making more sound colours available to the sophisticated synthesist... Radikal by name, radical by nature, now a swarm of oscillators need not take up too much valuable rack space, so why not add one (or more) modules to your setup today to start putting Radikal Technologies’ latest DSP-driven design through its unique-sounding paces?

Now shipping, the RT-311 SWARM OSCILLATOR is available for purchase from Radikal Technologies stockists at an MSRP of €598.00 EUR (in Europe) and $659.00 USD (in the US).

Dog in the woods

Published on Feb 6, 2017 Jörg Schaaf

"I shot this video with the little campark 4K UHD extreme camera (ACT73R) with 60 frames/second 1080p. The footage has been edited in Final cut Pro. In most cases I added some coloring with the sepia filter plugin. Sounds are mainly from the Radikal Technologies Accelerator, RT-311 swarm oscillator, RT-451 multimode filter and the strymon timeline. The track has been published last year in summer for the first time and had a different name in the beginning. It was called "homage to the strymon timeline delay". In this video I did some doggy overdubs and added some complex pad work at the very end. BTW.: For the close to ground and tree detail footage I used a simple selfie stick ;-)"

New Radikal Technologies EFFEXX RT1701 Multi FX Processor Eurorack Module

EFFEXX RT1701 Multi FX Processor Demo 1

Published on Jan 6, 2017

"That is the first demo of our new Multi FX Processor for the Eurorack Modularsynth world - the EFFEXX RT1701"

New details via Radikal Technologies:

"Radikal Technologies showcases the brand new RT-1701 EFFEXX Multi FX-Module for the eurorack world. This new FX unit combines multiple FX processors with Radikal's powerful snapshot animation feature. Create the most astonishing FX morphing sounds and control them with external control voltages from envelope generators, step sequencers or LFOs. For the first time, we are also presenting the Release version of the Swarm Oscillator RT-311 that recently hit the US market. We are at in Hall C, boothnumber 4803.

The RT-1701 features a gain stage with saturation, a very flexible EQ/Filter section and 2 selectable DSP effects for the modern electronic musician. The following effects are available: Reverb, Delay, Chorus, Phaser, Flanger, Tremolo, Vibrato, Filter. Effect combinations and settings can be memorized in up to 8 snapshots for every program. The snapshot blender allows for creating smooth transitions between the different snapshots. The blender can be controlled by an internal LFO or with external control voltages. By blending from one snapshot to the next, the module produces a mix between the two FX snapshots."

RT-311 Swarm Oscillator: Short Demo Video 1

Published on Sep 17, 2016 Jörg Schaaf

"OK - I have to admit that I had some saturation from time to time at the VCA but beside that, you get a first impression, what you can do with snapshot recalls. After tweaking the knobs a little bit I show the remote control via the data output. So, I am controlling the Cutoff frequency of the RT-451 filter. Then I recall some oscillator snapshots. Beside interpolating between these snapshots they can also be used to recall fixed settings. In this example I synchronised the internal LFO of the swarm oscillator and recall the snapshots with that LFO as presets. Every eight steps it increases the snapshot number by one.

Afterwards I play a cluster, tune the beast up with that cluster, change it to a chord and tine it down again. That video represents only a few of the swarm oscillators features. Our first shipments will be done by the end of october 2016."

dawn of the swarm interpolator

Published on Sep 1, 2016 Jörg Schaaf

"The RT-311 Swarm Oscillator has a parameter snapshot interpolator, that creates continuous and smooth blends between different snaphots. The Spread pot controls the number of snapshots that get interpolated and the Speed controls the interpolation speed. This is the first demo of it. In the next video you will have the chance listening to the interpolation for the first time. The track in the background is a demo, I created around 10 years ago with the Spectralis and a chorus and phaser fx."

Radikal Technologies RT-311 Scale Experiments

"I am using the following modules for this example:
RT-311 Swarm Oscillator
RT-451 Dual Multimode Filter
A-147 VCLFO
The soundcraft signature MTK22 mixing desk internal FXs tape delay and room reverb.

The pitch input of the oscillator has a scale quantizer. The Scale Quantizer allows for converting a continuous control voltage into a music scale"
