DELTA CEP A Workshop Reihe (1) Pilotfilm - Übersicht

Jörg Schaaf

"Trade fairs are cancelled. Workshops are postponed. In times of the pandemic, product videos are a serious alternative. I had a video series on the DELTA CEP A in mind for a long time. The first part provides an overview, while the following parts deal intensively with the individual sections of the synthesizer. My personal highlight in this pilot episode is the use of the stereo tape delay of the FX section as a looping device for a spontaneous 5 minute improvisation. This version of the video is in German. An English version will surely follow if I receive demands for it. Anyway - the audio demos will not change at all in an english language version.

Messen fallen aus. Auf Workshops wird verzichtet. In Zeiten der Pandemie sind Produkt-Videos eine ernstzunehmende Alternative. Eine Video-Reihe zum DELTA CEP A schwebte mir schon lang vor. Der erste Teil dient einer Übersicht, während sich die folgenden Teile intensiv mit den einzelnen Sektionen des Synthesizers auseinandersetzen. Mein persönliches Highlight ist die Nutzung des Stereo-Tape-Delays der FX-Sektion als Looping Device für eine spontane 5 minütige Improvisation. Diese Version des Videos ist in deutscher Sprache gehalten. Eine englische Version wird sicherlich folgen, wenn dieses Format Zuspruch findet."

Arp Fields - ARP 2500 live in concert

Pablo Garreton

"Arp Fields, for ARP 2500 synthesizer.

The composition was performed live with an 8.1 surround system at the Hochschule für Musik und Tanz, Cologne with the support of the Studio for Electronic Music.

All the sounds are generated live with the ARP 2500, the Doepfer modular is used as a mixer and for some LFOs. There is also an Expert Sleepers audio interface to send CV triggers to sync the spatialisation and some LFOs. All the pitches are manually adjusted with the controls of the ARP synthesizer. This modular system has a total of 12 oscillators. The synthesizer has not ever been restored, hence some parts where not working 100%.

All the sounds were spatialized with algorithms and LFOs in live with a custom Max/msp for the 8.1 surround system, controlled with a midi controller.

Impro no. 572 - Arp 2500, EMS Synthi & Doepfer A100

"I found this video from when I was preparing and exploring for my concert with the Arp 2500 at the Studio for electronic music of the HfMT In Cologne. I’m am using ableton and M4L for synchro, custom LFOs and some mixing. After a while I decided I should do a piece only with the Arp 2500 sounds, as you can can see in my feed, I have a video of a live concert with this. Improvising in the studio is relatively easy compared to play in a live concert with this incredible machine, that has never been properly restored. The sound and the energy is still there anyway.

Ratcheteer - Semi-Automatic MIDI Pattern Generator


"The RATCHETEER generates MIDI note patterns easily, working in sync with Ableton Live's transport with options for numerous time divisions and the ability to be performed using external MIDI controllers.

Assign a MIDI Note to ratchet and choose from 5 types of time division to hear the note re-triggered from a steady pace to rapid fire mayhem. Select an output velocity with fixed, random between a range or LFO controls.

Turn the knob or play your keyboard to play the ratcheteer at different speeds. It'll output expressive MIDI notes which can be recorded as clips and stored in your track.

The Ratcheteer is ideal for Trap Hi Hat petterns, but can be used on any drum or synth hit. It can also be used on multiple channels for entire rhythm track making.

Time divisions include triplets, whole notes, dotted notes, all combined and free (unclocked).

Use the MIDI Map function to change the ratchet using MIDI controller movements, from knobs, faders, mod wheels or pitchbend. You can also automate numerous elements to store within your track.

Send ratcheted MIDI notes to VSTs, Drum Racks or external MIDI Hardware using Ableton's extensive MIDI routings. Say goodbye to meticulous MIDI finessing and start performing hi-octane hi-hat patterns!

Please Note: Ableton Live 10 Suite is required to run this device."

Isotonik Studios JJBURRED - Factorsynth 2

Demo - Factorsynth 2 Isotonik Studios

"Factorsynth is a one-of-its-kind device that uses machine learning to deconstruct any sound into elements. After 2 years of the initial release comes Factorsynth 2, the first major update. Following many user suggestions and requests, version 2 is an even more versatile yet easier to use device, with a simplified workflow and numerous new features. It is now possible to individually pan the components, allowing to do things such as upmixing a mono clip to stereo. Another powerful new feature is the quantized shifting of the components, which allows changing the rhythmic structure of riffs and drum loops. A second, alternative decomposition algorithm is available, as well as a more detailed control of the playback region."

Patch and Tell: Buchla 291 Fun - Modular Synthesizer Demonstration - 258 - Frequency Modulation

The Galaxy Electric

"Thanks for tuning in! Come on a musical voyage with us where we'll send you a new song every day, a cosmic story, and a chance to earn space treasure:

This is a basic demonstration of the 291 vintage buchla filter clone by Roman Filippov. I am using it in conjunction with the 258 dual oscillator clone by Dunnington Audio, UK as well as a Buchla USA 281h/292h combo. The filters are being used in parallel. The Q setting is at top of its range. I have them calibrated for a modest max Q setting. I have a randomly generated pattern emitting from the 218e using a latched arpeggio.

The 291 Dual Voltage Controlled Filter is made up of two bandpass filters with adjustable Q, Center Frequency, and Bandwidth. The Center Frequency and Bandwidth are also voltage controllable.

Vintage ARP Omni 1 Keyboard Synthesizer Overhauled with LED Sliders SN 2483 1698

Synth Chaser

via this auction

"This synthesizer has just been fully serviced by Synthchaser, the United States' top ARP specialist - recapped, new key bushings, new LED sliders, new reliable pushbutton switches, clean, fully functional, calibrated, in tune and sounding great. This keyboard is the sound of Joy Division and is all over The Cars' "Moving In Stereo", and many other late 70's/early 80's albums. It produces the lush Solina/String Ensemble sounds plus has a polyphonic synthesizer section with a voltage controlled filter, LFO, and ADSR, and a dedicated bass synthesizer section.

Has a some scratches on the case, which is common to these synths, see photos. However, the keyboard sounds great and has been completely overhauled inside with hundreds of dollars of new parts and many of hours of labor, including:

Synthchaser Precision LED slider upgrade. All 15 of the old original sliders have been replaced with new, smooth, high precision LED illuminated sliders. The difference in the way these sliders feel and perform compared to the originals is a huge improvement. The LED colors match the color scheme of the panel graphics.

Illuminated slider caps - Slider caps with a translucent plastic stripe that allows the LED illumination to shine through, while giving you something substantial to grip onto. I just started using these caps, and they look and feel awesome!

Synthchaser replacement pushbutton switches - All 10 of the original pushbutton switches (which are notorious for having the mechanical latches break) have been replaced with retrofits. The original switch caps are still installed so they look the same from the outside.

Power supply rebuilt - All tantalum and electrolytic capacitors in the power supply have been replaced, and high quality, high temperature 105 deg C capacitors have been used for the power supply filter capacitors.
All tantalum capacitors replaced - The tantalum capacitors in ARP synths are ticking time bombs. All of the over 100 tantalum capacitors in this synth have been replaced with electrolytics to help provide stable operation for years to come.

Synthchaser 4075 Filter Enhancement Kit Installed - The ARP Omni uses the same 4075 filter submodule found in the Odyssey, Quadra, Avatar, and Pro DGX. This has been recapped, and enhanced to provide superior frequency response.
Keyboard rebuild - New key bushings installed, buss bar & key contacts cleaned, key contacts adjusted, and keys ultrasonically cleaned

Oscilloscope calibration - Fully calibrated to factory spec using oscilloscope and frequency counter."
