Sounds like: A lead where notes slide into each other instead of jumping.
A monophonic lead where glide between notes is the entire character — the melodic equivalent of Portamento Slide Bass, played higher and generally with a brighter tone.
Open this patch in the interactive PatchpadPortamento is set on TRIG page 2: PORT turns it on and PTIM sets the glide time. In the track's SETUP menu, PORTAMENTO TYPE decides what glides: TRACK glides from the last note played on the track, and LEGATO ONLY glides only between overlapping notes. GLIDE style is an ordinary continuous slide; GLISSANDO quantizes it to semitones. Everything else is a plain, unaggressive carrier so the glide stays the focus. FDBK acts on operator A in ALGO 1, so LEV (A) is raised to 50 on SYN page 2 to let the feedback colour carrier C; LEV (B) stays 0 and MIX -64 selects the C output only.
Portamento is on TRIG page 1: PORT turns it on and PTIM sets the glide time. In the track's SETUP menu, LEGATO ONLY ON makes the pitch glide only between overlapping notes, and STYLE GLIDE is the ordinary continuous slide (GLISSANDO quantizes it to semitones). Melodic tracks use Digital machines, not Analog. AMP PAGE 2's MODE must be ADSR or SUS on AMP PAGE 1 is ignored.
Glide is in the VOICE section: choose a monophonic Voice Mode (Mono or MonoLG; MonoLG glides only between overlapping legato notes, while Mono always glides between successive notes), turn Glide On, and set Glide Time short-to-medium. On the AMP ENVELOPE menu, MonoTrig Legato stops the envelope re-triggering on overlapping notes, which only works in the Mono or MonoLG modes.
Osc 1 is BasicWaves with Morph at 50 (pure sawtooth): the Morph knob runs from a square (0) through a sawtooth (50) to a double sawtooth an octave up (100), Sym only changes the pulse width below 50, and Sub adds a sine an octave down (0 here). MiniFreak's monophonic Legato/Glide performance mode is exactly what this patch needs -- a real performance-setting requirement, not a synthesis parameter. Set Glide/Portamento time short-medium from the performance settings alongside monophonic Legato. 0-100 scale for the synthesis values above. Values are on MiniFreak's native 0-100 scale.
Front-panel knobs are physically unmarked, described by clock position; the OLED pages use the 0-100 convention.
VOICE page 1 sets POLYPHONY to Mono, and page 2 has GLIDE (Off / Glide / Glissando), GLIDE TIME (0-127), GLIDE CURVE (Exp to Lin to Log) and GLIDE LEGATO. With Glide Legato On only notes played legato slide, so detached notes retrigger cleanly. The filter and envelope values are the synthesis side of the patch.
Melodic-register sibling of Portamento Slide Bass — same performance/sequencer setting requirement (glide + legato) as the primary sound-design element.
