𝐑𝐀𝐕𝐄𝐍 — 100% Analog. Synthesizer Voice [Black Panel]

𝐑𝐀𝐕𝐄𝐍 — 100% Analog. Synthesizer Voice (2021 Rev 1.5)
<< Black panel version >>

This is a single unit from the 2nd batch of 2022 - PCB Rev 1.4; BOM Rev 1.5

𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻:
𝐑𝐀𝐕𝐄𝐍's system-architectural idea was about going back to the basics of subtractive synthesis. We wanted to capture the raw, non-linearity, and honesty of a 100% analog circuit. The main engineering challenge of 𝐑𝐀𝐕𝐄𝐍 was consolidating a highly complex conglomerate of modular, discrete designs into a slim 3U/42HP (Eurorack) form-factor resulting in a uniquely sounding subtractive,
modular, high-performance, musical instrument.

𝐑𝐀𝐕𝐄𝐍 is comprised of:

• Dual, wide-range Voltage Controlled Oscillators (C1-C9), unison trackable with extensive FM/AM/PWM possibilities.
• Dual, wide-range Low-Frequency Oscillator (ca. 0.1Hz - Audio) switchable mode.
• A high-headroom, Voltage Controlled Crossfader (A/B).
• The original TheBateleur (Ⓡ pending) Voltage Controlled Filter.
• Two Voltage Controlled Amplifier circuits - A high-performance THAT2162 BlackmerⓇ VCA and an Optocoupler VCA reminiscent of legendary West-Coast designs as a serial-saturation option.

𝐑𝐀𝐕𝐄𝐍 combines the simplicity of a performance-friendly, semi-modular synthesizer voice with fully modular, infinitely flexible, workflow possibilities by assigning Control Voltage I/O’s at (almost) every point in the signal workflow.
Each modular component can be seen as a standalone, self-sufficient entity.
The normalized VCF can be used as a standalone 24dB LPF or 3rd Oscillator-voice in self-oscillation range, perfectly tracking 1V/Oct by choice.
