Qu-Bit Electronix Bloom

Name: Bloom
Brand: Qu-Bit Electronix

Fractal sequencer growing infinitely evolving melodies from one seed

16 HP Eurorack module

Bloom is a Qu-Bit Electronix fractal sequencer with two independent channels, each capable of generating evolving melodic patterns through mutation and branching algorithms. It features scale quantization, clock division/multiplication, ratchets, slew, and extensive CV control for generative music applications.

Features

Fractal sequencer with recursive tree generation from user-programmed trunk sequence
Two independent channels each with up to 32-step trunk sequences
Up to 256 steps of generated fractal sequence per channel (7 branches deep, 128 paths)
Generative modifications: transposition, inversion, reversal, and mutation
Path control determines traversal direction through fractal branch tree
Branches control sets depth of fractal recursion from 0 to 7 additional branches
Mutation control introduces randomness into trunk sequence notes
Per-step slew control with independent amounts per step
Per-step ratchets allow repeating a step for multiple clock pulses
Per-step gate length control with 8 lengths from 6ms trigger to tied
Scale quantization: Chromatic, Major, Minor, Major Pentatonic, Minor Pentatonic, Harmonic Minor, Whole Tone, Unquantized
Playback order: Forward, Backward, Pendulum, Random

Controls & Jacks (36)

Length— Sets the sequence length from 1 to 32 steps
Scale— Selects the musical scale for quantization
Order— Controls playback order: forward, reverse, pendulum
Pattern— Selects between stored sequence patterns
Channel— Switches between the two independent sequencer channels
Reset— Resets sequence to step 1; also serves as manual trigger
Root— Sets root note for the scale quantizer
Div/Mult— Clock divider/multiplier relative to clock input
Path— Controls branching path direction at branch points
Slew— Adds portamento/glide between notes
Branches— Sets probability of sequence branching into alternative paths
Ratchets— Adds retriggering within a step for rhythmic interest
Mutation— Probability of random note mutations on each cycle
Notes— In Shift mode, selects which step to edit
Root CV— CV input for modulating root note selection
Branches CV— CV input for modulating branch probability
Reset In— Trigger input to reset sequence to step 1
Shift— Modifier button for accessing secondary knob functions
Rate— Internal clock rate when no external clock is patched
Clock In— External clock input, overrides internal clock
Out 1— Pitch CV output for channel 1
Out 2— Pitch CV output for channel 2
Gate 1— Gate output for channel 1
Gate 2— Gate output for channel 2
Clock Out— Clock output from internal or processed clock
