About

sqsl Latch

This app is a conceptual MIDI controller and sequencer for creating drone, textural, and soundscape synthesizer patches. It allows for sending MIDI notes, pitch bend, and CC values with advanced looping and parameter modulation features. Save and recall your setups for later use.

Highlights
  • MIDI note, pitch bend, and CC output
  • 16 groups with assignable MIDI channel and color
  • 8 assignable Continuous Controllers per group
  • Looper for recording and shuffling note phrases
  • Adjustable phrase playback speed and synchronization
  • Parameter modulation via internal randomizer
  • Smooth parameter transitions with LAG control

sqsl Latch is a conceptual MIDI controller and sequencer designed for working with evolving drone, textural or soundscape synthesizer patches. It can send out MIDI notes, pitch bend and CC values. There are 16 groups split into 2 banks (a, b, c, … p). Groups have assignable MIDI channel, color and 8 Continuous Controllers (CC). When user touches one of the pads, note is activated and is held on until new touch (on the same pad) is registered. Left slider controls the velocity of note to be activated. Every group has a looper able to record note state changes - phrases. Order and velocity of recorded notes is automatically shuffled after phrase restarts (can be optionally prevented by activating group’s LOCK button).  Phrase playback speed is adjustable (CLOCK and DIVIDER parameters). Phrase can be synchronised - set to restart automatically with previous group's loop. Synchronisation can be set to happen on every pass, every second, third... up to 16th and can be set to be ignored randomly (probability setting 0-100%). Group parameters can be adjusted using sliders or modulated by internal randomiser with adjustable range (RANGE and RANGE 2 parameters) and speed (per group LAG control - left-most slider). Apart user definable CCs, each group has following MIDI parameters: MOD (mod wheel), BEND (pitch bend), VOL (volume), EXP (expression), PAN (pan), FOOT (foot controller), TOUCH (aftertouch/channel pressure). Group parameters related to phrase playback are: CLOCK (resolution and playback speed), SYNC with divider (loop synchronization), NOTE SKIP (randomly skipping notes events 0-100%), SYNC SKIP (randomly skipping sync events 0-100%), DIVIDE (integer group's CLOCK divider), LOOP (loop or one-shot setting), SHIFT (degree offset with selected scale). LAG can be applied to parameter changes - when new value is selected, change does not happen immediately but value is transitioned smoothly based on LAG time (left-most slider). Setup setting (CC numbers, channels, colors, and MIDI output) are saved and recalled when app is restarted. Loops, CC values, parameters and their modulation states can be written to preset positions for later recall.

About

Weeping Wall

This app creates evolving soundscapes by automatically recording and layering new audio input into independent microloopers. It offers extensive controls for loop size, repitching, and randomization, allowing for unique sonic textures. Designed as a modular tool, it integrates seamlessly with other audio effects for creative sound design.

Highlights
  • Automatic microloopers with input detection
  • Independent loopers with variable size
  • Repitching and reverse controls
  • Jitter control for random variations
  • Beat and transport syncing
  • Live performance mode
  • Modular tool for creative sound design
Features
Read full description

Weeping Wall is a standalone app and AUv3 plug-in. WW is a set of microloopers that automatically record based on input detection. Each new sound will be smoothly introduced and replace older sounds, resulting in a group of sounds that always reflect the most recent input. Each looper behaves independently - their size can vary and they will beat against each other as they phase. Up to 5 loopers are available to record into, with repitching and reverse controls as well. A dedicated “jitter” control allows you to randomly vary the size of each looper on each loop, creating variations that will never be heard again. Weeping Wall can be used as an effect directly on a track, or as a send effect. WW is intended to be a modular tool; it doesn’t include reverb, EQ, saturation, flutter, etc., but it plays extremely well with them. WW is a brand new effect that can be used in any number of creative ways - you can place it fully wet in front of a reverb, place a hint of it behind a saturator, combine it with your favorite pitch modulation - whatever you can dream. WW is fully compatible with automation and modulators such as Ableton CV to broaden the horizons even further. Weeping Wall has the following controls available: Threshold: The volume at which input will start recording into a looper. Looper size: The size of loopers, in seconds, from 0.1s to 3s. Jitter: A control for desynchronizing loops. Loops will be randomly shortened, and each one is free to change size independent of one another. Semitones: Repitch loops, with a range of +/- one octave. Reverse: A latching control to reverse looper playback. Looper number: Up to five loopers are available. Hold time: How long loops will be held before fading away, from seconds to forever. This essentially controls whether WW functions more as a looper or as a delay. Independent dry and wet volumes: Use WW as an effect directly on your track, or as a send effect. Beat syncing: Loopers can be synced to your tempo, from 1 whole measure to 1/64th notes. Macro-looper mode: Loops can grow to up to 60 seconds in length. Transport syncing: Loopers can be paused or destroyed on pause. Live performance mode: Enables a button-based UI designed with live performance in mind. Random skip: Loops can be randomly skipped over with some probability. Crossfade length: Control the length of the crossfade occurring at the start/end of each loop to keep sharper transients or smooth them off. Fade time: Control how long loops take to fade in/out. Filters: The wet channel can be high or low pass filtered for dialing in your sound.
