New workshop Video: Radikal Technologies – Delta CEP A

We recently did a modular workshop at SchneidersLaden in Berlin. Workshops at SchneidersLaden are taking place always on Saturdays. They always start with a little modular improvisation. We are very happy that the staff at SchneidersLaden produced a great video of the entire workshop. So if you missed it you can watch it now. You will learn a lot about the Delta CEP A and in the second chapter about the Radikal Modules as well.

New workshop Video: Radikal Technologies – Delta CEP A

Radikal Technologies Workshop @ SchneidersLaden

Donnerstag, 20.02.2020 19:30

Jörg Schaaf aka Radikal Technologies will be in Berlin to talk about (and show) his latest synthesizer designs like the Delta Cep A. He is responsible for some modern classic synth designs from 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. His complex designs always bring a lot of functionality to the table and they can sound amazing.

See and hear for yourself during the workshop at SchneidersLaden.

Start: 7:30pm @SchneidersLaden

Participation is free / No registration required

Delta CEP A missing presets download

Unfortunately we shipped 6 units to different dealers with the new OS 1.5 but without the preset data. Below you’ll find two soundfiles with the missing preset data. One of them overwrites the USER PRESETS and the other one overwrites the ROM Presets. A big sorry to customers, who received a unit without our soundset.

The installation of the soundsets is quite simple:
1.) Connect the audio player output to the external input in the MIXER section of the DELTA CEP A which is just between the oscillator and the filter section. It is not necessary to setup the ext. signal level as the unit detects the input data independent from the set gain.
2.) Set the DELTA CEP A into PATCH SELECT mode by hitting PATCH if not already done.
3.) Play the complete file to the Delta CEP A. The LEDs left from the big knob will show the progress. It will count the snapshot memories 40 times for 40 presets with green LED lights for USER memories and yellow for ROM presets. If the level is too high the LEDs turn red. In that case just restart from the beginning with less volume.
4.) When the file has been received completely, the unit will show the pink LED lights of the PATCH SELECT mode again.

WARNING: The file with the User presets overwrites all your own user presets. But you can backup them. You’ll find all informations about that in the owners manual.

Delta CEP A Version 1.5 released

We are pleased to announce that our DELTA CEP A and DELTA CEP A Desktop products have received an extensive update. This firmware update is available to all customers and our dealers free of charge. Devices that we have delivered since 09.09.2019 have already been equipped with this new firmware.

The following features are additions by the new version:

  • the [SHIFT]-key can now be locked in, additional parameters can also be reached without holding the [SHIFT]-key.
  • In addition to the previous effects, there is now a reverb that can be used simultaneously with the other effects.
  • The LFO can now be routed to a lot of destinations without patch cords. 
  • The ADSR can now be routed to a lot of destinations without patch cords.
  • Each modulation target has an independent modulation strength setting.
  • The sound programs of the DELTA CEP A can now be switched over via MIDI.
  • The LFO can now be synchronized directly to a square wave signal.
  • The volume and  saturation intensity of the oscillator signal can now be modulated by a control voltage.
