Tonestar 8106

EurorackAnalogMonophonic

Imagine squeezing a complete ARP 2600-inspired synth voice into a tidy 32hp Eurorack panel, with every knob and patch point begging for hands-on tweaking. This module captures that raw, vintage vibe while adding modern modular flexibility, making it a go-to for basslines, leads, and everything in between.

At its heart sits a premium VCO blending ARP, Oberheim, and Moog circuitry for rock-solid tracking across a huge range, outputting saw, triangle, square, and sub waveshapes that mix into a fat composite signal. The standout "Jupiter to Juno" filter pairs a 6dB/oct highpass with a 24dB/oct lowpass recreation of Roland's IR3109, complete with voltage-controlled resonance, drive for harmonic grit, and tap points at 6dB, 12dB, or 18dB slopes—bypass it with the triangle for extra low-end punch. Voltage-controllable LFO and ADSR envelope feed a VCA, all pre-patched for instant sounds yet fully modular via 21 patch points and 27 knobs plus 6 switches; it draws 130mA on +12V and 80mA on -12V, with 35mm depth.

Modular folks love its dense functionality in a compact footprint, praising the versatile filter's musical bite and the VCO's stability, though some note the bold color scheme isn't subtle. It's a premium entry point for analog subtractive synthesis, perfect if you're building a smaller rig craving classic tones with patchable surprises.
