Synch Festival 2008

via Bakis of Parallel Worlds

"i will be making a 3-hour analogue modular synthesis workshop (practical use of analogue modulars) based on the Doepfer A100 modular during the 3 days of Synch festival.

details for the workshop below:

Analogue Modular Synthesis

The workshop is focused on the application of the basic methods of synthesis(Subtractive, FM, AM) on analogue modular synthesizers (the Doepfer A-100 analogue modular synthesizer will be used as an example):
Application of analogue VCOs, LFOs, Envelopes, VCAs, Ring modulator, Waveshapers, Sample and Hold for the creation of simple and intricate sonic tones, drums and sound effects in the modular environment.
Connection with cv / gate keyboard controller. Application of analogue step-sequencers and analogue modular synths as real-time sound manipulation tools (interactive link between sound source and analogue modular). Practical application of analogue modulars and MIDI.

Instructor: Bakis Sirros

thanks,
best regards,
Bakis."

"Unsigned home studio recording of electronic trance music. This is 'old skool' trance, or my take on it at least. When I made it about 15 years ago it wasn't 'old skool'.

Made with Atari, Cubase, Yamaha SY35 and DX7, Korg Poly 800 pus another Atari with Replay 16 sampler."

Vintage Session: TB-303; TR-606; TR-707; RZ-1 etc by Queaver

YouTube via kwiwer. via synthzoom.
"short jam session while using some vintage gear like Roland TB-303; TR-606; TR-707; Alpha Juno and Casio RZ-1, except Acidlab Bassline 2 as second acid line and the Korg Electribe SX for the bassdrum and for triggering the Juno while using the Electribe's filter. The audio recording is clipping a bit, because the gain poti was a bit to loud ;)"

Chronology part 6 - on Bontempi Hit organ

YouTube via organfairy. via synthzoom.
"Chronology part 6 by J.M.Jarre. Most of it was played as a MIDI file using "Noteworthy Composer" for Windows. Bass arpeggio was played on Roland JX8P, strings and choir on Yamaha HE-8 organ, the rest was played on the computer's Yamaha XG soundcard - except the solo. The solo is supposed to be played on an accordeon. But since I don't own an accordeon I used the "green monster" instead. The "Bontempi Hit Organ" was made in the 70's and was actually quite common. It is a simplified accordeon with an electric pump instead of a bellow. However, it's not very good as it lacks the nessesary pressure to play fast. But what could I expect from something I got for 5 dkr. (0.8$) at a jumble sale..."

VCO synchronization made visible

YouTube via MusicMiK. Be sure to see the others here.
"Did you ever wonder, what really happens with VCO sync? Here you can see it.
I made this video during development of another VCO, my synchronization master is just a provisoric square oscillator, which produces a very unclean signal. Besides this i don't have the audio equipment in the lab to create a better audio on this :) But the main syncronization effect is visible and hearable.

Schematics might be released soon, after drawing and final check."
