Dual Slew Limiter / Portamento Eurorack Module - BIGZUN GLIDE, 4HP

BIGZUN GLIDE is a compact 4HP dual slew limiter (portamento) for Eurorack, fully assembled and tested. It smooths out voltage jumps: when the input changes abruptly, the output follows smoothly at a constant rate - giving you portamento, gentle envelopes and soft transitions between CV values.

Two independent channels, A and B, each with its own RISE and FALL knobs. With nothing plugged into IN B, channel B receives the signal from IN A - so one CV can get two different glides.

Use cases

- Portamento on sequencer pitch CV

- One CV, two glides - two oscillators drifting apart and meeting again

- Envelope from a gate (RISE = attack, FALL = release)

- Shaping an LFO - square into trapezoid or triangle

- Smoothing random / sample & hold voltages for slow Berlin School style modulation
