Colossus supersized synth trips back to the future of analogue, symbolising more than a powerful analogue ‘workstation’ and with no fewer than 12 VCOs.
With 12 VCOs and eight VCFs, Colossus musically matches the aforesaid extensive and expensive Synthi 100, yet comes complete with a whole lot more besides. Indeed, its oscillator panel is well specified in its own right. There, the FREQ (frequency) — pitch — range of OSCILLATOR 1 through to OSCILLATOR 12 is extremely wide, and each can also be used as an LFO (Low-Frequency Oscillator); each features four waveforms, plus pulse width, oscillator sync, and sub-oscillator abilities. All are complemented by a SAMPLE AND HOLD generator, RANDOM VOLTAGE GENERATOR, and two pink/white noise generators — namely, NOISE GENERATOR 1 and NOISE GENERATOR 2.
The filter panel features four multi-mode (hi-, band-, and low-pass) 12dB filters — FILTER 1 through to FILTER 4, the circuit for which was originally based on the filter found in the classic dual-oscillator Oberheim SEM (Synthesizer Expander Module®) created by legendary American synth designer Tom Oberheim back in 1974, albeit Analogue Solutions skilfully applied some heavy-duty modifications of its own. On top of that, there are also four low-pass 24dB transistor ladder filters — FILTER 5 through to FILTER 8 — featuring a ‘Moog’ style sound. Saying that, all eight VCFs have serial VCAs (Voltage-Controlled Amplifiers), so there are actually eight VCF/VCA combinations in total! That’s not all as this panel also houses two mechanical spring reverbs — REVERBERATIONS 1 and REVERBERATIONS 2, each featuring a triple spring tank; two RING MODULATORS; two voltage SLEW LIMITERS; and four envelopes — ENVELOPE SHAPER 1 through to ENVELOPE SHAPER 4 — with ATTACK, DECAY, SUSTAIN, and RELEASE controls, alongside hold repeat and gated repeat trig (trigger) MODE functions.
