      EFFEXX - Vintage Delay Demo - Jörg Schaaf
One of the most popular FX algorithms nowadays is a vintage style tape delay emulation. The modification of the delay time caused a pitch change because you moved the head directly at some devices or/and switched to another motor speed what involved acceleration effects. The EFFEXX sports up to two of these vintage delays simultaneously plus reverb, post EQ and pre overdrive. With other words – you can create really spectacular SFXs with the module. As a sound source I used the RT-311 Swarm Oscillator and the RT-451 Dual Multimode Filter. Furthermore I added three Doepfer modules to this setup – the A-155 Analog Trigger Sequencer, the A-132 Dual VCA and one A-140 envelope generator.

Some Impressions from the 2017 Modular Synth Convention “MODCON” in Vienna. Thanks to Lara and Erwin from Raw Voltage for their invitation to participate. We are looking forward to join the convention again next year!


Tom Wies from Synth Anatomy recorded some video footage during the event and asked me to produce a little ambient backing track for the video. So you hear an improvisation with the swarm oscillator, the RT-451 multimode filter and the RT-1701 Multi Effects processor “EFFEX”. The sequence was triggered by the doepfer eurorack step sequencer. I did an overdub with some notes on the Accelerator.

I uploaded that audio file to soundcloud earlier today but for any reason the soundcloud version was full of glitches. So I uploaded the file to our homebase. You are listening to a dry pad sound from the Spectralis. I faded in three different FXs beginning with a Stereo Flanger, followed by a stereo delay and ending with an additional reverbration FX. At the end of the soundfile I am removing the FXs again and you can listen again to the dry version of the file. All FXs are playing in realtime from a single EFFEXX module.

The RT-311 sports an input stage with overdrive, two selectable main effects plus a Reverb and an EQ. In this audio snippet you are listening to filtered echoes and the reverbration effect of the new RT-1701 “EFFEXX” eurorack module. This combination creates a nice psycho ambient dub atmosphere.

The latest demo of the RT-1701 EFFEXX Multi-FX Module

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.

New firmware version for the Swarm Oscillator – Neue Firmware für den Schwarm Oszillator

Posted on Leave a commentPosted in Downloads, Eurorack Modules, News, Radikal Technologies, RT-311 Swarm Oscillator, Uncategorized

A new firmware has been released for the RT-311 Swarm Oscillator. This updates offers an improved FM quality. You maybe already recognized tickering sounds when tweaking FM parameters. We thought, lin. and exp. FM will benefit from a new Firmware, that refuses these sounds from coming up.

That is the first firmware update for the Swarm Oscillator. The active firmware shows up during Startup. The uppermost LED lights up blue and the next to the right red, if the firmware is already installed. If not, please check my step by step instructions below:

1.) Download the audio file at the following link or use the audio player below:
2.) Connect a cable from any audio player to the Swarm Oscillator’s SPEED Input.
3.) Load the update wave file into an Audio player like VLC Player, Itunes, Media Player etc. or play the file direct with the audio player below. The new version is called “SwarmVCO_V1.2.wav”.
4.) When you hit the play button, you will see a progress instantly in the LED ring. At the beginning of the transmission, the Oscillator enters the UPDATE mode. The entering shows up as a red LED animation. After that the first LED starts to run through all the colors multiple times. Each LED stands for a received Data block. As soon as a block has been received completely, the according LED turns from a purple LED color to white. So you can watch the transfer progress by checking the white LEDs. When all LEDs turned to white and the data has been checked to be OK, all LEDs will turn red for a couple of seconds. It is very important, that your have no power fail during these five seconds. When flashing has been completed successfully, all LEDs will light up green. Now you can reboot your Oscillator by powering down and up.
5.) During the data transfer something can happen. Maybe a power loss or your player jumps to a different track, the cable get diconnected etc. In such a case the LEDs turn red again. You can simply start the transmission again from the section, where the upload was still OK.
6.) The update procedure requires 4 minutes and 20 seconds.

Finished? OK – then let’s try the new FM quality of your Swarm Oscillator!

This player plays the firmware file – that is not an audio demo! Dieser Player spielt die Firmware Daten ab. Es handelt sich nicht um eine Audio Demo!



Für den RT-311 Swarm Oscillator ist eine neue Firmware erschienen. Das Update enthält eine stark verbesserte FM Modulation. Vielleicht hatten Sie es bereits bemerkt. Bei der bisherigen FM Modulation war stets ein rhythmisches Knacksen zu vernehmen, was einem den Spaß an der FM Modulation etwas verhagelt hat. Wir dachten, die meisten Anwender werden sich sicherlich über eine neue Version freuen, die diese Störgeräusche eliminiert.
Dies ist das erste Firmware Update für den RT-311 Swarm Oscillator. Wenn Sie unsicher sind, ob ihr Modul das Update bereits erhalten hat, schalten Sie es einfach ein. Bei aktiver Version 1.2 leuchtet die LED auf 12 Uhr blau und die rechts davon rot. In dem Falle brauchen Sie kein Update durchführen.

Folgendermaßen wird das Update durchgeführt:

1.) Laden Sie das Update unter dem folgenden Link oder verwenden Sie den Wave-Player oben.
2.) Verbinden Sie den Ausgang ihres gewählten Audio Players mit dem SPEED Eingang des RT-311 Swarm Oscillators.
3.) Laden Sie die entpackte Audio Datei in einen Player ihrer Wahl (VLC Player, Media Player, iTunes etc.) und starten Sie die Wiedergabe. Bei dem Player in diesem Artikel müssen Sie lediglich die Play-Taste betätigen.
4.) Wenn Sie die Play-Taste betätigt haben, läuft zunächst eine Leucht-Animation mit roten LEDs ab. Sie zeigen an, dass der Oszillator in den Update Modus versetzt wird. Direkt im Anschluss beginnt die erste LED mit einer Farbanimation. Die übrigen LEDs leuchten rosa. Sobald ein Programmblock geschrieben wurde, wechselt die Farbe der aktuellen LED von rosa nach weiß. Zeitgleich beginnt die Farbanimation der nächsten LED. Die Firmware ist in ihrer Gesamtheit übertragen, sobald alle LEDs weiß leuchten. Nach der Übertragung startet automatisch der Flash Vorgang. Während des Flash Vorgangs leuchten die LEDs rot. Während dieser Zeit darf der Strom nicht unterbrochen werden. Das Gerät muss sonst zum seriellen Flashen in den Service. Das Schreiben der Firmware dauert lediglich 4 Sekunden. Wenn das Flashen beendet ist, leuchten alle LEDs grün. Nun müssen Sie noch einmal rebooten, in dem Sie den Strom aus- und wieder einschalten. Danach ist die neue Firmware im Einsatz.
5.) Wenn etwas schiefläuft, passiert dies in der Regel während der Übertragung der Daten. Jemand startet aus Versehen zusätzlich eine andere Audio Wiedergabe oder zieht das Kabel ab. So etwas ist schnell passiert. Der Swarm quittiert einen solchen Übertragungsfehler mit rot leuchtenden LEDs. Zusätzlich läuft die Animation der aktuellen LED weiter. Wenn Sie einfach die Wiedergabe vor den Bereich des Übertragungsfehlers neu starten, nimmt der Oszillator die Übertragung mit dem aktuellen Block wieder auf.

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.

First Audio Demo of the RT-1701 EFFEXX Multi-FX-PROcessor

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.
A high resolution frontpanel picture of the front panel can be found here.
