Sentence

Sentence is a creative tool for scheduling musical events with triggers and gates.

Four colored modules (Red, Blue, Yellow and Green) play one after the other. Each one repeats a tempo-synced duration, from a full bar down to a 1/32nd, as many times as you like. Change the repeats and durations and the chain of modules becomes a rhythmic sentence: short phrases, long pauses and odd groupings that loop in time with Reason’s clock.

Under the modules, a 16-step sequencer is driven by those same triggers. It builds gate patterns that can run poly-metric against the triggers that drive them, and those gates decide how likely a trigger is to fire. You set one probability for active steps and another for inactive steps, so the pattern breathes without ever losing its structure.

You can store up to eight patterns, mutate them, reshuffle them and chain them into a song with Parade!, a 12-flag arranger that plays each pattern as many times as you choose before moving on.

Sentence produces no sound of its own. Patch its outputs into step sequencers, envelopes, drum modules, samplers or anything else that responds to a trigger or a gate.

Workflow design by _bES, coding by DOODOV.

Modules

• 4 identical modules (Red, Blue, Yellow, Green) that play in sequence and loop
• Repeats per module: 0 (inactive) to 32
• Durations as a division of one bar: /1, /2, /3, /4, /6, /8, /12, /16, /24, /32
• Each module shows its total length in ms
• Outputs per module: onset trigger (fires once when the module starts) and repeats trigger (fires on every duration)
• Combined outputs: combined module onsets and combined repeat triggers

Module Control

• Global [X] and [.] controls adjust the repeats and durations of all modules at once
• Reorder the modules by dragging their labels
• Readout of the combined length (ms/s) and of the total count in the lowest common duration

Trigger Probability

• Master probability from 0 to 100%, applied to the individual and combined repeats triggers
• Separate balance sliders for on active step and on inactive step

Step Sequencer

• 1 to 16 steps, advanced by the combined repeats triggers (not affected by probability)
• Click a step to toggle it active or inactive; shift the whole pattern left or right with [< >]
• Per-module outputs: active stage trigger and active stage gate
• Global outputs: act. trig, change trigger (fires when a step changes between active and inactive), act. gate, gate inv
• S&H IN: an external CV is sampled on active steps and output on act. gate (first step of each active run) and act. trig (every active step)

Pattern Storage

• 8 pattern slots (A–H), each with its own step sequencer, plus a silent “_” slot that counts time without firing
• wipe, copy to, reorder modules and mutate pattern tools

Parade!

• 12 flags, each assigned a stored pattern and a play count from 0 to 8
• Flags set to 0 and empty flags are skipped; the sequence loops back to the first flag
• flag advance trigger output on each flag change

Global

• Lead: shifts all triggers and gates up to ±120 ticks (1/32nd) against the Reason clock
• Play starts and stops the device, follows the Reason transport and always stops when the transport stops
• Reset restarts the pattern or the Parade! and sends a manual reset trigger
• Mute silences every output while the pattern keeps running
• Send 1 fires a single trigger on every trigger port and overrides Mute
• CV-only device, no audio I/O
