One Knob To Rule Them All

"Diego Stocco The Conduit Shaping the Soundtrack LCO 3

I like to experiment with small electronic instruments, like the optical theremin. The pitch of this circuit responds to the intensity of external light, which makes it hard to play specific notes.
I wanted to find a better way to control not just the pitch but also the trigger of the sound in order to create rhythmic patterns. I used che chassis of an old device to host the circuit, connected a dimmer to control the intensity of a light bulb and a push-button switch to break the circuit, so I could control the note on/off. To fatten up the sound I connected it to a spring reverb, an hi-fi amp and two old speakers, recorded with a stereo microphone. The instrument needs to be be played in semi obscurity."

Update: some video via Diego:

"The LCO is an instrument I assembled when I was creating the score for "The Conduit". I used it as a starting point to create a variety of bass sounds, ambiences and strange noises.

In this particular session I was also post-processing the sound of the LCO with modulated chains of comb-filtered delays and reverbs.

P.S. Careful with the volume, the sound gets pretty intense in the second half of the video."

"Short demo of the sound of the SCI Pro-One mono synth monster.
The only FX was Sonar 8's built in VST Lexicon reverb which is put across the whole finished track.
Seven mono tracks in all recorded in real time. I used the Pro-One's sequencer for the riff.
Thanks for listening.
The track is called 'Ambi-One'"

"hand made (from a diy kit?) moog filter clone from latvia.

cutoff pot crackling a bit. adsr functionality not quite correct.

when gate->adsr is switched off the gate input can be used as cv->cutoff amount.

waveform is dry sawtooth signal direct out from roland SH-7"

Yamaha CSY-1 ( SY-1 ) Analog Synth / Organ GX1 Filter

via this auction

"In 1974 Yamaha released their first ever synth, the SY-1 which was also available in the rare form of the CSY-1 which we have here, a funky 2 manual organ with the SY-1 built-in and playable from either the upper keyboard or the 13 note bass pedals.

The sound is amazing, organic, unique and very expressive too thanks to Yamaha's excellent pressure sensitive keyboard (aftertouch) which can be assigned to various parameters. The presets are pants as you'd expect but get tweaking and it really comes to life. It's something a bit different. The sound is in my opinion very similar to the mighty Yamaha GX-1's monosynth section and I have been told that they even share the same filter circuitry, if not more. (The GX-1 was made in 1975). If you can't find a GX-1 for sale or just don't have £100,000 or so to pay for one but simply must have that bubbly warm early Yamaha sound then here's your solution.

From the CSY-1 operation manual, "Do not be alarmed if sound rattling (sympathetic vibration) occurs. All materials have critical resonance frequencies at which they vibrate. Since the CSY-1 produces continuous tones, it is only normal that some will cause windows, shelves etc. to rattle."

The CSY-1 has it's own amplification/speakers built in and even has a real built in Leslie type 2 speed rotary speaker, the synth sounds great through this and the spring reverb is very sweet too.

Have a listen to Royksopp, see if you can spot it, it's one of their favourite synths. You can get an idea of the sounds on Youtube. Search for Yamaha SY1 / SY2, there are a few demos, also search for a Youtube video called Synth Barocco, the soundtrack is exclusively CSY-1. You can also download the whole CSY-1 manual if you go to the Yamaha online manual library."
