Frequency Central System X - Snappiest ADSR in Eurorack

Mint

• 4HP ADSR built on Roland System 100M behavior
• Full ADSR panel control: ATTACK / DECAY / SUSTAIN / RELEASE — simple knobs, real envelope work, fast to patch, hard to overthink.
• Fast/slow RANGE switch — one module covers sharp plucks and longer sweeps instead of being locked into one timing feel.
• Normal + inverted outputs — one gate gives two opposite moves at once: open a VCA while pulling a filter down, ducking modulation, or flipping motion without burning another inverter module.
• Gate input fires the envelope directly — sequencer, keyboard, trigger/gate source, logic module, clock divider: plug gate, shape sound, done.
• Red LED shows envelope voltage movement — instant visual feedback, so you see the shape while hearing the patch react.
• Verified compact specs: 4HP, 45mm deep, 7mA +12V, 7mA -12V, 0mA 5V — very low case cost for a full ADSR with dual-polarity output.
• Punch-focused envelope behavior — SchneidersLaden describes it as small but very snappy, with shortest attack settings that avoid obvious clicking. Strong for tight VCA hits, bass gates, filter pings, and dry percussion-style articulation.
• Where basic compact ADSRs usually stop at “one envelope out,” this goes harder: range switch + normal output + inverted output + full ADSR controls in 4HP.
• Patch roles: VCA snap, filter pluck, mono synth voice contour, bass punch, percussion hit, inverse filter ducking, one-gate two-destination movement.
• Small module, big control. It does the boring ADSR job, then adds the smart stuff — timing range and inverted output — that saves patch cables, HP, and extra utility modules.
