"Back to the raw power and purity of discrete analog - where Studio Electronics started in 1985!
Boomstar is the ultimate desktop analog synthesizer for those who remember and desire the electronic analog sounds that changed the world. Choose between four models, each corresponding to a classic filter type:
4075: Classic Arp 2600
5089: Classic Moog 24db ladder
SEM: Classic Oberheim 12dB/Oct with sweepable Low-pass through High-pass
303: Classic Roland TB
The Boomstar is a superior analog music machine made in the USA. From it's discrete voltage controlled analog oscillators, to it's hand matched transistors in its filters and amplifiers, no compromises have been made and no corners cut. This is the real deal for those seeking truly fat analog sound at a reasonable price. The snap and punch of hardware envelopes drive the Boomstar's brilliant voltage controlled circuits with unparalleled sonic integrity and versatility. The Boomstars are even semi-modular, with easy to access front mounted CV and Audio inputs and outputs for different routing possibilities and use with other hardware. This is not your average modern analog synthesizer!
The Sound Engine and Controls
All discrete circuity. Hand matched transistors in filter and amplifier.
Oscillator 1:
6 position rotary octave range switch
Two center-off toggle switches select combinations of sine, triangle, saw and square waveforms
Pulse width for square waveform
Sub oscillator with center off toggle switch for half and full level positions
Sync oscillator 2 to oscillator 1 switch
XMod: Oscillator 2 mod depth knob with center off toggle switch to select modulation of oscillator 1 pulse width or oscillator 1 frequency.
Oscillator 2:
6 position rotary range switch
Three position toggle switch to select triangle, saw or square waveform
Fine tune knob
Mod depth knob with center off toggle switch to select modulation by envelope 1 or 2
Keyboard tracking on-off switch.
Mixer:
Oscillator 1 level knob
Oscillator 2 level knob
Ring Modulator level knob
Noise level knob
Feedback knob.
Filter:
Frequency and resonance knobs
Center off toggle switch to select half and full keyboard tracking
Envelope mod depth knob
Additional mod depth knob with center off toggle to select modulation by oscillator 2 or the LFO
Envelope 1:
