sqsl Lottery ‪٤+‬

sqsl Lottery is a "sequential weighted probability matrix MIDI note sequencer".

there are 5 parameters used to generate notes: KEY (semitone), OCT (octave), VEL (velocity), TIME (including mutes) and CH (MIDI channel). For every parameter there is a matrix where columns represent value and “buttons” in column represent possible destination values. Current value is indicated by colored-highlighted column background. Value that will follow (after current value) will be selected from activated destinations/buttons in the current colum.

For example: for KEY/semitone parameter (C, C#, D, D#…), there are 12 + 1 columns, each containing 12 buttons. The first column defines “what will happen after C note is played”. If button E and F is activated in the first column, after C note, sequence will progress to note E or F. Each button/key has its probability “strength” = likeness that it will be the selected destination. Probability strength is indicated by brightness and is set by tapping on button. The actual strength value is decided randomly when tapped and can be continuously changed by PHASE touch strip. PHASE affects all probabilities in the current matrix so PHASE changes result in new probability routes.

In case there are no destination selected in the current column (all buttons have probability 0), sequence will advance to OFF-labelled column on the left (and no note will be played). If there is only one button activated (set to have probability higher that 0), it will be the chosen destination regardless of its value. Dot is drawn in the middle of the button if its probability value is higher than 0 (to differentiate 0 from low value).

There are 5 voices, each can produce one note at a time. Voices share probability settings of KEY, OCT, VEL, TIME and CH parameters. Voices have separate direct control for clock density, clock division, swing, gate length, octave offset, MIDI channel offset and semitone transposition.

Main parameters (key, octave, velocity, time, channel) can be “remapped” - for example by default, first column of key matrix represents C value but it can be mapped to any other semitone. This allows changing the resulting note patterns without necessity to rearrange the probability matrix.

There is global clock rate control that affects the main tempo and each voice has its clock division, clock density, swing and gate length settings. There are 8 pages each with 96 slots for storing current state (presets).

Notes:
- sqsl Lottery is a standalone app sending out only MIDI notes.
- sqsl Lottery it does not produce sounds/audio on its own.
