RS370 Polyphonic harmonic generator - Samples

via Bakis on AH:

click here for the samples

"For the above audio demo clips the following has been used: apart from the sound source that is an Analogue Systems RS-Integrator modular (including two RS370's, two RS375's and two RS290's), many Doepfer envelopes, multiples, mixers, vca's, lfo's, plus Metalbox/CGs, sequential switches, Gated Comparators, Burst generator, Pulse Divider/ Logic, VC Divider, Gate Sequencer, Digital Noise, plus Blacet VCO's, Attenuator. Reverb, Delay and Chorus from Sony and Roland Digital Effect processers have been also added sometimes."

MOONMODULAR trigger sequencer M563

"Prototyp test of the M563.

Text from the http://www.Matrixsynth.blogspot.com YUSYNTH says: "This Moon Modular 563 module is apparently the commercial version of a module that was custom-made for Gert Jalass. For Xmas 2006, Gert Jalass sent me a Xmas card showing his sequencer unit including two prototypes of the module that were labelled 963. This is a four voices 8 steps trigger sequencers.
Each switch has three states:
Trigger on, OFF, reset.
The pulse width of the triggers can be adjusted independantly for each row.
The module has a clock of its own, but each row can be independantly driven by an external clock."

The M563 drives two ARP sequencer, one ARP for the VCOs and the second for the VCF of a minimoog."

Amplitude Modulation, AM

"What is amplitude modulation?

In order that a radio signal can carry audio or other information for broadcasting or for two way radio communication, it must be modulated or changed in some way. Although there are a number of ways in which a radio signal may be modulated, one of the easiest, and one of the first methods to be used was to change its amplitude in line with variations of the sound.

The basic concept surrounding what is amplitude modulation, AM, is quite straightforward. The amplitude of the signal is changed in line with the instantaneous intensity of the sound. In this way the radio frequency signal has a representation of the sound wave superimposed in it. In view of the way the basic signal "carries" the sound or modulation, the radio frequency signal is often termed the 'carrier'."

Note the John Bowen Solaris features AM. You can read about that here.

"Good Evening Mr.Echo" Gattobus LIVE Experiment

YouTube via gattobus
"I made this video about a month ago. It was an experiment using an old Ibanez Analog Delay AD100 I found at work in the shop. The song wasn't very good so I didn't upload it at first, but... what the hell... It was fun while playing it, so here it is...
I also added some tutorial comments about the sounds..."

Inside a Roland SH2 Synthesiser

via David:
"We had to replace the pot (slider) for the LFO rate as the speed varied randomly. Unfortunately we couldn’t find an exact match so the LFO now runs fast than it did before!

Now that it’s fixed, we use this synth a fair bit in our band, Destination Moon. Probably the most prominent use is in ‘Just Out Of Reach.’ This features the SH2’s white noise being filtered, with the filter cutoff modulated by the LFO in sample and hold mode. Meanwhile the bass guitar is played through the synth, so it’s filtered in sync with the white noise. Then we added violin and voice over the top, plus some whooshes (more white noise!) from an Alpha Juno.

If you think your readers might be interested in hearing this, they can download the song from
http://www.destinationmoonband.com/Reach.html
There’s no link to the download from the main part of our website, so this would be sort of an exclusive for Matrixsynth readers."

Interviews: Wowa Cwejman by Bryan Erickson.

You can find the interview on VAC.

"I took it upon myself to interview Cwejman because I need a little bit more information about his products. Well, that was one of the reasons. The other reasons were that I felt that there is not enough coverage about these products and their creators. There are a lot of synth companies out there now making new and interesting analog synthesizers that have their own sound and bring something new to the table. Cwejman makes a full synth and Modules for the Eurorack(doepfer) modular systems. I wanted to pick his brain on a few subjects regarding his products. I seriously am fed up with most magazines that cover this gear. I wanted an even more in depth form of covering and asking questions about this gear that true synth-nerds will understand. I cannot thank him enough for answering my questions."
