CD-Tip V : Anthology of Dutch Electronic Tape Music Vol 1 and 2 - Various Artists

These summer weeks i have been too busy to blog regularly, but i did have time to read and listen.
The main topic of this summer's research was Early Dutch Electronic (Tape) Music, you can expect the review of the book "Onder Stroom" (in Dutch) by Jacqueline Oskamp later, but first this quick quadruple CD-Tip.

This 2 x 2CD collection gives another nice overview of the early Dutch Electronic and Tape-pioneers.
It shows the listeners that there were more creative people interested in the spectrum between noise and sound besides the people who worked at the Philips NatLab (more info HERE and Wiki HERE).
A collection of work from throughout the Netherlands from Dutch legends like Dick Raaijmakers, Henk Badings, Ton Bruynèl, Tom Dissevelt and more from the years 1955 to 1966 fills up Volume 1.
Volume 2 has music from the years 1966 to 1977 and contains compositions of lesser known tape-artists that were not included on the first volume.

More Blue LEDs

Okay... I haven't had much time to write and post these last weeks because i'm too busy working this summer, but i'm not completely sitting still.

The new blue LEDs that I ordered arrived, so the next few weeks i will only be replacing some red LEDs by blue ones.
It's not the most exiting modification, but it will make my A-100 system more pretty IMHO.
( Info on replacing LEDs HERE )

I do have time to read during my work, and i'm reading a very interesting (Dutch) book called "Onder Stroom" by Jacqueline Oskamp at the moment.
This book tells the story about the history of electronic music in the Netherlands, so expect a book-review of that in the near future.
( The book is slightly related / overlapping  THIS )

I will be back with some more interesting posts in a few weeks... so please stay tuned!

CV / Gate Cable Length

A few times I've been asked about how patch-cable lengths ( of CV and/or Gate signals ) can affect signal strength.
I found a few interesting posts in the Yahoo Doepfer Usergroup that might make things a bit clear to you.

First of all;
Gate cables even longer than 10 meters usually are no problem.
Although a gate signal might get slightly weaker when you use extremely long cables, the (simple) gate signal will often stay strong enough to trigger your modules.
CV-Cables of this length may have a slight loss depending on the electrical characteristics of the input and the output.
There are ways to measure it,  but it is very difficult to judge whether a not completely clean octave tracking is caused by long cables.
Real loss of signal quality starts with asymmetric audio cables at such a length, and you have always to keep in mind that electromagnetic and electrostatic influences (hum and sizzle) can affect longer cables more than shorter cables.

Doepfer Usergroup Poll: Analog Shift Register

Another new Poll at the  Doepfer A100 Modular System Users Group is up.
This time it is about the idea of realizing a Doepfer Analog Shift Register A-100 module.

A few days ago this was posted:
" ...It has been a while again, so I'll bring it up again. I believe it is time for a Doepfer analogue shift register... Does anyone agree with me?... " (*edited)

To be honest, i had never heard of an Analog (or digital) Shift Register, but a quick search on the web provided some hugely interesting information.
For the basic theory on what a Shift Register does i'd advice you to read the Wikipedia page first.

For the musical use and a brief history on Analog Shift Register modules there is an excellent post at, describing most of the known Shift Register modules.

" Ok, so what is an ASR? An ASR module is a sophisticated S&H. It will, at every clock pulse, sample the CV value of the input and makes it available at the first output. So far, …
