Gliss 1U

Bela

24 HP Eurorack capacitive touch-strip controller in Intellijel 1U format. Produces two high-resolution CV outputs from finger position and touch size, with modes for real-time control, gesture recording/playback, CV/audio signal processing, and a 5-note tunable keyboard/sequencer. 23 RGB LEDs provide visual feedback.681

Capabilities 4

CV Generatorcv-generator
Outputs two CV signals from finger position and touch size via Output 1 and Output 2 in Control Mode.681
CV Processorcv-processor
In Signal Mode, processes incoming CV or audio by scaling, offsetting, clipping, and smoothing; outputs processed signal and/or envelope detector.681
Gesture Recordergesture-recorder
Records up to 150 seconds of gesture data and plays back via Loop, Trigger, Clock, Wavetable, or Waveshaper modes.681
Touch Keyboard / Sequencertouch-keyboard
In Notes Mode, the Touch Strip is divided into 5 individually tunable notes playable as an expressive keyboard or step sequencer.681

Parameters 13

NameTypeRangeBehavior
Envelope Decaymenu_settingContinuous setting controlling smoothing applied to the decay of the envelope detector output. Slide towards bottom for less decay, top for more. Returns to red at default value.681
Input Signalmenu_settingSelects whether the input is treated as CV (DC coupled, shown as a moving point) or audio (AC coupled, shown as a level meter).681
Latchingmenu_settingDetermines whether output voltages are held (latched) when touch ends. Unlatched: outputs go to 0V on release. Latched: outputs hold last values. Latch Position: position-mapped outputs hold, touch-size outputs go to 0V.681
LED Brightnessmenu_settingGlobal setting. Continuous slider to adjust LED brightness from minimum (bottom) to maximum (top). Returns to red at default value.681
Module Orientationmenu_settingGlobal setting. After changing the faceplate, drag the red point to re-orient all menus and controls. For 1U version, drag to middle. Automatically reorients all menus and output labels.681
Output Typemenu_settingSelects what the two outputs carry in Signal Mode: processed+inverted, processed+envelope, or envelope+inverted envelope.681
Play Typemenu_settingSelects whether the 5 tunable notes are played as an expressive keyboard (touch-triggered with vibrato and glissando) or as a step sequencer triggered by clock input.681
Playbackmenu_settingSelects the playback mode for recorded gestures in Record Mode. Options: Loop, Trigger, Clock, Wavetable, Waveshaper.681
Quantisationmenu_settingWhen ON, note pitches are stepped to 12-TET semitones during manual tuning (12 semitones per volt). When OFF, any voltage level is achievable.681
Slew Ratemenu_setting0s – 100sSub-menu with four continuous selectors for attack and release slew rates of Output 1 and Output 2 independently. Default is 0 (immediate). Maximum slew time is 100 seconds. First 40% of strip = 0–1s, next 40% = 1–10s, last 20% = 10–100s.681
Touch Input Typemenu_settingSelects the touch input type for Control and Record modes. Options: Single Slider (position + touch size), Dual Slider (two independent position sliders), Dual Touch (two pressure pads), Slider + Touch (80% position slider + pressure pad).681
Touch Sensitivitymenu_settingGlobal setting. Scales touch size measurement by applying gain. Slide point from bottom (no gain) to top (maximum gain). At maximum, any touch immediately sends voltage from 0V to the maximum of the selected voltage range.681
Variable Settingmenu_settingIn Keyboard mode: sets vibrato depth (range of frequency variation when wiggling finger). In Sequencer mode: sets glide amount between steps. Continuous setting.681
