Single VCO with multiple waveforms
“Arch” 424 is a voltage-controlled oscillator. This VCO’s frequency range is wide, Can be used as VCLFO. It can produce four waveforms simultaneously: square, sawtooth, triangle, PWM and sine wave (sawtooth shape is not perfect yet). The frequency or pitch of the VCO is determined by tuning (Pitch and Fine) knob, and by the voltage present at the CV inputs.
You can control the pulse width of the square wave either by hand, or by voltage control – Pulse Width Modulation or PWM.
If perfect pitch is required better VCO is recommended. For a perfect sawtooth this is not recommended.
Envelope follower 424
Envelope follower with Preamp
The preamplifier has an instrument input as well as standard with gain control, it can be used on its own too.
Envelope follower with range control.
Prototype AD/AR envelope generator
Does it work or attack, not and good, Delay or Releases?
Filter based on K 700
More info later…
Even more printed circuit boards !
New LFO/FILTER/VCA boards.
Brick 424 is a patchable mini semi-modular synth.
VCO – saw and square out. 2 CV in and PW.
2 x LFO – One with CV contro. saw & square.
White Noise out.
One A/R envelope.
Minimaeen is a little analogue bass/effect synth, with very kool sound tweaking abilities.
Built around 2 Philips NE5517. Its oscillator has selectable square and triangle wave output. Diode ladder filter with it’s screaming cutoff and resonance, makes tweaking a joy.
Minimaeen has a low frequency oscillator that can be routed to the voltage controlled oscillator or the filter cutoff.
The envelope can be trigged by pulse or a push-button on the panel controlling the voltage controlled amplifier or/and cutoff frequency. Continue reading Minimaeen 424
