It’s a **burst generator / trigger delay** that turns one trigger or gate into a fast series of triggers. That means its melodic usefulness comes from how it **drives other modules**: - sequencers - sample & hold - quantizers - envelopes/LPGs - clock dividers/multipliers - switches - logic - trigger-to-gate or trigger-to-envelope utilities So for melody, think of Brst as a module that creates **repeated note events, ratchets, grace notes, strums, arpeggio-like trigger clusters, and delayed re-articulations**. ## What Brst does From the manual: - **TRIG input** starts a burst when it receives a trigger/gate - **PULSES** sets how many triggers are generated - from **1 to 32** - **RATE** sets the time between triggers - about **10 ms to 500 ms** - **PULSES CV** and **RATE CV** let you voltage-control those two parameters - **TRIG toggle**: - **left** = include the initial trigger - **right** = omit the initial trigger - **OUT** emits the burst as **0–5 V triggers** This makes it especially good for: - ratcheting one note into many attacks - creating repeated sampling events - stepping a sequencer multiple times from one master clock - making a melody “flutter” or “bounce” - delayed note echoes in trigger form --- # Best ways to use Brst for melodic music ## 1) Ratcheting a sequenced melody ### Patch - Send your main rhythm trigger or sequencer gate to **Brst TRIG** - Send **Brst OUT** to the envelope or LPG that opens your melodic voice - Keep your pitch sequence going from another sequencer into the oscillator pitch input - Adjust: - **PULSES** for number of ratchets - **RATE** for ratchet speed ### Result Each note in your melody can fire multiple times quickly, creating: - trance-style ratchets - IDM stutters - ornamented melodic phrases - repeated plucks on a single pitch ### Musical use This is the most direct melodic use: - same pitch, multiple articulations - great for plucks, FM bleeps, acid lines, and arpeggio voices ### Tip Use the **TRIG toggle left** to include the first hit immediately, then the extra repeats follow. --- ## 2) Burst-clocking a sequencer for fast melodic runs ### Patch - Main clock or manual trigger into **Brst TRIG** - **Brst OUT** into the **clock input of a sequencer** - Sequencer pitch CV into oscillator 1V/oct - Envelope/VCA triggered either: - by the same **Brst OUT**, or - by a separate gate source ### Result One incoming trigger can advance the sequencer several steps very quickly, producing: - mini arpeggios - melodic fills - fast ascending/descending runs - pseudo-strums if the sequencer has chord-related voltages ### Why this works Brst effectively turns one musical event into **multiple sequencer advances**. ### Tip If you modulate **PULSES CV**, some notes create short runs and some create long runs. That gives phrases more expression. --- ## 3) Quantized sample-and-hold melody generator This is one of the strongest melodic pairings. ### Patch - Noise, random CV, or slow modulation source into **Sample & Hold input** - **Brst OUT** into **Sample & Hold trigger** - Sample & Hold output into **Quantizer** - Quantizer output into oscillator 1V/oct - Use the same **Brst OUT** or a derived gate to trigger your envelope ### Result Each burst creates several new quantized notes in quick succession: - random melodic flourishes - clustered ornamentation - “bouncing ball” melodies - generative lead lines ### Tip - Slow **RATE** = clearly separated melodic notes - Fast **RATE** = clustered trills or grace-note runs - Low **PULSES** = subtle ornamentation - High **PULSES** = long random cascades --- ## 4) Arpeggio-style phrases from sequential switching If you have a switch or sequential switch, Brst gets very musical. ### Patch - Feed several fixed voltages or pitch CVs into a sequential switch - Clock the switch with **Brst OUT** - Switch output into a quantizer or directly to oscillator pitch if tuned - Trigger your envelope from **Brst OUT** ### Result A single trigger produces a rapid sequence of different pitches: - chord strums - arpeggiated bursts - broken chord ornaments - harp-like plucks ### Great source material Put into the switch: - root / third / fifth / octave - notes from a chord - different rows of a sequencer - transposition voltages This turns Brst into a **melodic phrase generator**. --- ## 5) Delayed melodic echoes Because Brst can omit the initial trigger, it can act like a trigger delay with repeats. ### Patch - Send your main melody gate to **Brst TRIG** - Set **TRIG toggle right** to omit the initial hit - Use **OUT** to trigger a second envelope/voice or re-trigger the same voice ### Result You get: - delayed note repeats - ghost notes - call-and-response attacks - melodic shadows ### Especially effective with - two oscillators tuned in intervals - a second voice an octave up/down - filtered echoes from a parallel voice Instead of audio delay, you get a **compositional trigger delay** that can generate new melodic articulations. --- ## 6) Ornament generation for sustained notes ### Patch - Main gate opens a long envelope on a voice - Same gate also goes to **Brst TRIG** - **Brst OUT** triggers: - a second short envelope to FM index, - a wavefolder CV accent, - filter pings, - or a VCA on a parallel voice ### Result The pitch may stay constant, but the burst adds melodic-style embellishment: - mordents - trills - flutter-tongue effects - repeated accenting on the note This is useful when “melodic component” means not only changing pitch, but adding **expressive note structure**. --- ## 7) Using Brst to create trills between two pitches If you have a switch, logic-controlled transposition, or dual pitch source: ### Patch idea - Main pitch CV goes to oscillator - A second interval voltage is available, such as +2 semitones or +7 semitones - Use **Brst OUT** to toggle a switch between the base pitch and interval pitch - Also use a related trigger to articulate the note ### Result One note becomes a fast alternation: - trill - mordent - alternating dyad gesture - baroque-style ornament Brst is excellent for this because the **rate** is controllable and can be CV-modulated. --- ## 8) Humanizing or varying melodic clocks The manual specifically mentions humanizing a clock signal. For melody, that means: ### Patch - Main clock/gate into **Brst TRIG** - Use low **PULSES** and moderate **RATE** - Feed **OUT** to a sequencer clock or auxiliary melodic event ### Result Instead of every melodic step being equally plain, some steps have: - extra ticks - repeated notes - little rushes - phrase-ending fills This is great in generative patches where a melody feels too rigid. --- # Voltage control strategies for melodic use ## PULSES CV Use this to vary how many notes/articulations a phrase produces. Good modulation sources: - slow random CV - sequencer row - envelope - keyboard velocity/mod wheel if interfaced - another rhythmic modulation source ### Musical effect - some notes are single hits - some are double/triple ratchets - some become long flourishes This adds **phrase hierarchy**. ## RATE CV Use this to vary the spacing of repeated notes. Good modulation sources: - random stepped CV - LFO - envelope for accelerating/decelerating burst feel - sequencer accent row ### Musical effect - fast grace notes on some steps - slower echoed notes on others - changing density across a phrase This is one of the easiest ways to make Brst feel alive. --- # Concrete melodic patch recipes ## Patch 1: Simple ratcheted lead **Needs:** pitch sequencer, oscillator, envelope, VCA - Sequencer pitch CV → oscillator 1V/oct - Main gate pattern → Brst TRIG - Brst OUT → envelope trigger - Envelope → VCA CV - Oscillator → VCA → output **Settings** - TRIG toggle left - PULSES: 2–5 - RATE: fast **Sound** A lead line where selected notes repeat rapidly. --- ## Patch 2: Random burst melody **Needs:** noise/random source, sample & hold, quantizer, oscillator, envelope - Random CV/noise → S&H input - Brst OUT → S&H trigger - S&H out → quantizer - Quantizer out → oscillator 1V/oct - Brst TRIG fed from a slow clock or manual gate - Brst OUT → envelope trigger **Sound** Each trigger creates a little cluster of quantized notes. --- ## Patch 3: Chord strum **Needs:** sequential switch or multiple fixed pitch voltages, quantizer optional - Several tuned voltages or chord tones → switch inputs - Brst OUT → switch clock/advance - Switch output → oscillator pitch - Main gate → Brst TRIG - Brst OUT → envelope trigger **Sound** One trigger strums through chord tones like a harp or guitar rake. --- ## Patch 4: Sequencer fill generator **Needs:** step sequencer, oscillator, envelope - Master clock or fill trigger → Brst TRIG - Brst OUT → sequencer clock - Sequencer CV → oscillator pitch - Brst OUT → envelope trigger **Sound** Instead of one note, a single event makes the sequencer run through several notes quickly. Great for: - phrase endings - transitions - fills between bass notes --- ## Patch 5: Delayed octave echo **Needs:** 2 voices or one voice with transposition path - Main melody gate → voice 1 envelope - Same gate → Brst TRIG - TRIG toggle right - Brst OUT → voice 2 envelope - Voice 2 tuned one octave above or fifth above **Sound** Each note gets a delayed answering note above it. --- # Performance ideas ## Manual triggering Brst is very playable when fed from: - a manual gate button - keyboard gate - pressure pad gate - gate sequencer accents You can use it to inject: - trills - fills - grace-note bursts - sudden arpeggios ## Accent-based use Instead of sending every note to Brst, only send: - accented steps - every 4th bar trigger - end-of-sequence trigger - probability-generated gates That keeps the melodic bursts special. ## Modulate only one parameter at a time For musical clarity: - modulate **PULSES** if you want varying phrase length - modulate **RATE** if you want varying urgency - modulate both only if you want chaos --- # Important limitations Brst does **not** itself produce pitch CV. So to make truly melodic material, pair it with at least one of these: - quantizer - sequencer - sample & hold - precision adder/transposer - sequential switch - oscillator/envelope voice Without those, Brst only creates rhythmic trigger structures. But in a Eurorack system, that’s often exactly what turns static pitch material into something musical and expressive. --- # Best musical roles for Brst in a melody-focused rack Brst is especially strong as a: - **ratchet generator** for sequenced notes - **ornament generator** for trills and grace notes - **burst clock** for fast sequencer runs - **random melody trigger source** for S&H + quantizer patches - **strum engine** for chord tone switching - **delayed re-trigger tool** for echoes and call-response phrasing If your system already has pitch sources, Brst adds the **articulation layer** that makes melodies feel less static. --- # Bottom line Brst is best understood as a **melodic event multiplier** rather than a melody source. It takes one trigger and turns it into a cluster of note opportunities. When combined with sequencers, quantizers, switches, or sample-and-hold, it can produce: - ratchets - trills - grace notes - arpeggiated runs - chord strums - delayed melodic echoes - generative note cascades In short: **Brst adds phrasing, ornamentation, and motion to melodic patches**.
