Description Bloom is a fractal sequencer capable of generating infinitely evolving melodies with a host of musical features. At its core is a powerful 32 step sequencer with two independent channels and an intuitive interface. What makes the Bloom come alive are its fractal algorithms which can transform existing sequences into powerful melodies, or even generate new patterns altogether.
Installation T o install, locate 16HP of space in your Eurorack case and confirm the positive 12 volts and negative 12 volts sides of the power distribution lines. Plug the connector into the power distribution board of your case, keeping in mind that the red band corresponds to negative 12 volts.
Concept Overview Bloom is a fractal sequencer that uses a user-constructed sequence to recursively gen- erate a tree of related subsequences that can be strung together to create large musical sequences that relate back to the originally programmed sequence. Everytime the trunk is adjusted, or mutated (via the mutation control) the entire tree is regenerated.
Generative Modifications These are the transformations that are applied within the recursive tree generation. T ransposition The previous sequence is transposed up or down by as much as one octave (twelve semi- tones).
Inversion The previous sequence is inverted so that the highest note in the sequence is now the lowest, and vice versa. Reversal The previous sequence is reversed so that the first note in the sequence is now the last, and vice versa. Mutation The previous sequence is mutated so that some of the notes are adjusted up or down as much as an octave, if your sequence takes advantage of different gate states, these can...
When all the way up, the “T runk” Sequence, and 7 related subsequences of the same length will extend the sequence. The LEDs will change color to indicate that the Bloom is in one of the branches instead of the “T runk” sequence.
-5V to +5V CV input added to knob position. CV only changes the currently selected channel. 5. Clock In Clock input to module. When the Rate knob is all the way down, this jack is enabled, and the internal clock will be shut down.
Holding the Channel button for 3 seconds will switch to the global editor The global editor is indicated by a white channel LED. When editing things in the global editor all changes will be made to channels 1 and 2. The following controls work separately for each channel: - Root - Path...
This consists of setting all pattern notes to the default pattern: • 8 Steps • Major Scale • Forward Order • No Div/Mult • No Ratchets • No Slew Unmutate Hold shift and tapping reset This will revert the current pattern to its state when the last manual edit was done, erasing any mutation changes mutation has caused.
The LEDs will indicate the selected pattern by illuminating a group of two LEDs from top to bottom. Pattern The Bloom can store up to 8 patterns in memory. A Pattern can be selected by holding shift, and rotating the encoder. T o LOAD the selected pattern, hold shift and click the pattern encoder.
T o COPY a pattern, hold the corresponding encoder (1-8 from top to bottom) and click the destination encoder (1-8 from top to bottom). Unlike the LOAD and SAVE functions, the COPY functions will work regardless of the cur- rently selected pattern. This is intended to speed up composition and performance. Div/Mult The Division/Multiplication in relation to the Clock rate can be selected by holding shift, and rotating the encoder.
T o exit the Per-Step slew editor, hold shift, and click the Slew encoder. T o adjust all steps’ slew at once, hold shift and rotate the Slew encoder while the sequencer is running. The LEDs will indicate the amount of slew from the top down. Ratchets Ratchets define the number of clocks that the sequence will remain on the selected step.

T o move forward a page, press reset. T o loop the page that is being edited press channel. It is also possible to edit the length of the gate for each step both while running and while in T une Mode. For each step, the gate length can be adjusted by pressing the encoder and rotating it.

For example, if you tuned your oscillator to 100Hz, each turn of the Div/Mult or Slew encoder should increase the frequency to 200Hz, 400Hz, 800Hz, 1600Hz, and so on. If you have a reliable voltage source you can insert 1V (or use the 1V from the Bloom, once its been fine-tuned) into the Root CV .

Pressing Reset again will store the 3V , and turn the T op Middle LED Green. Pressing Reset again will store the values for OUT 1, turning the Bottom Middle LED Green. Pressing Reset again will store the values for OUT 2, and turn the bottom most LED Green. T o exit the mode, and save these settings between power cycles, hold channel for 2 or more seconds, and then tap shift.
