Analog Synth DIY Percussions Controller Preview

YouTube via Redled72
"Heute geht es um ein interessantes und sehr flexibel einsetzbares Modul, den Percussions-Controller.
Mittels Mikrofon können zB. Percussionsklänge erfasst und anschließend verschiedene Steuersignale gewonnen werden. Das Modul liefert folgende Signale:

-positives Kontursignal (AD regelbar)
-negative Kontursignal (AD regelbar),
-verstärktes Audiosignal,
-Hüllkurve (positiv),
-Gatesignal (positiv),
-Trigger (positiv) mit einer Impulslänge von 20ms

Eine LED visualisiert das Gatesignal. Hüllkurve (Attack + Decay) kann per Potis geregelt werden. Verstärkung (Mikrofon) ist regelbar zw. 1 & 1000."

"Today it is an interesting and highly flexible module, percussion controllers.
Mic agent can, for example. Percussion sounds are recorded and then won various control signals. The module provides the following signals:

Contour-positive signal (AD adjustable)
Contour-negative signal (AD adjustable),
-amplified audio signal,
Envelope (positive),
-Gate signal (positive),
Trigger (positive) with a pulse duration of 20ms

An LED visualizes the gate signal. EG (attack + decay) can be controlled by potentiometers. Gain (microphone) is adjustable btwn 1 & 1000th"

Kawai 100f Analog Synthesizer (1980)

YouTube via agnus2112
"Estos son algunos de los sonidos vintage que solamente se pueden conseguir con este gran instrumento de 1980.
El sintetizador se encuentra con su circuito en buen estado pero sus teclas presentan un problema con los osciladores que hacen que las notas se disparen y cueste controlarlo en la mayoria del teclado.
De todas formas es una maquina que suena increible, siendo ideal para generar atmosferas con efectos de ruido blanco, simulando rafagas de viento y mareas, iguales a los que hay en algunos discos de Pink Floyd y otras bandas de Krautrock como Tangerine Dream, CAN, y los primeros Kraftwerk. Ademas posee una alta gama de frecuencias que se combinan y alteran hasta generar un autentico muro de sonido.

"These are some of the vintage sounds that can only be achieved with this great instrument of 1980.
The synthesizer circuit meets her in good condition but its keys have a problem with the oscillators that make the notes soar and cost control in most of the keyboard.
Anyway, it's a machine that sounds amazing and is ideal for generating atmospheres with white noise effects, simulating gusts of wind and tides, the same as those in the disc of Pink Floyd and other Krautrock bands like Tangerine Dream, CAN, and early Kraftwerk. You have a high range of frequencies that are combined and altered to create a real wall of sound."

Octave Cat SRM Analog Synth

via this auction
"S/N for this beauty is B3257.
The mono-/duophonic 'Cat' is a 70s analog synth with an architecture designed very closely after the famous arp odyssey. The term 'SRM' stands for 'series revision model', so it is an improved version with additional interfacing options and ssm-based filter, there is also a 'SRM2' model in existence. The Cat features 2 vco's, one with pulse width modulation, both with a sub oscillator, vco1 and 2 can be adressed separately in the 'duophonic' keyboard mode, like in the Arp Odyssey. This technique uses the internal keyboard voltages, so this will not work with external control voltages. To add to the feature list, the Cat offers a mixable noise signal, a resonant 24db lowpass filter, one adsr-envelope and one ar-envelope with retrig option and furthermore a lfo as well as sample & hold. The lfo is permanently synced to the gate signal, so it automatically restarts when a new note is played - often useful, sometimes limiting.

The strongest point about the Cat is modulation, there is an abundance of modulation possibilities on oscillators and filter - pwm, sync and crossmodulation from vco1>vco2 and vco2>vco1 simultaneously and independently, all with very precise control. VCO1 can be switched out of the audio path, if things get too nasty. The various vco waveforms and suboctave signals are available in parallel, each one having their own slider - this comes in extremely handy with sync and cross mod sounds. The filter can be driven into self oscillation and is controlled by lfo, sample & hold or one of the envelopes and above all offers frequency modulation by vco1. Interfacing is possible via a cv/gate stereo jack, inputs for pedal control of vcf and vca and even an external signal input to the filter are available.

Soundwise, the cat's dominant impression must be 'powerful', things can get very thrashy and harsh, but there are always nuances where strange and beautiful timbres evolve, and there are enough control possibilities given to sensibly pinpoint a certain sound. Generally the sound is positively like 'ancient electronics', it can provide anything from deep bass, to powerful percussive sounds, to complex noisescapes, and it brings in a character all of its own."
