Geode (abstract)

Geode is a rhythmic engine for polymetric & polyphasic patterns. This is fundamentally a ‘clocked’ mode, whether internally or via Teletype. TIME & INTONE maintain their standard free-running influence.

Notes are a combination of a standard trigger along with a repeat count & subdivision. The former sets the number of envelope events to create, while the latter chooses the rhythmic relation of those repeats to the master timebase. transient / sustain / cycle chooses how the repeats’ amplitude is modified over time. sustain decays to zero-level over the duration of the repeats. cycle adds a rhythmic undulation to the envelope level, controlled via the RUN jack. Experiment!

Once these rhythmic streams are moving, their pattern can be locked to a quantize amount. Using odd-subdivisions with even quantize or vice-versa will enable patterns to break out of the evenly-spaced repeat model.

Tick-tock

The timebase for Geode can be established through two different uses of one command:

JF.TICK clock/bpm

• clock/bpm: 49 to 255 directly sets tempo to 49-255 bpm
• clock/bpm: 1 to 48 define how many ticks equal one measure, sent repeatedly through tap-tempo from Teletype. eg JF.TICK 4 meaning four notes per measure

JF.TICK 0 resets the timebase to the start of the measure.

Look who’s talking, as well!

(These movie title references are almost over.)

Cut from the same cloth as Synthesis, Geode also utilizes JF.VOX and JF.NOTE in its own tongue. Instead of lush grumbles and glassy tones, Geode speaks in streams of rhythmic envelopes on a named channel, dutifully repeating at a rhythm defined by a division of the clock’s measure.

JF.VOX channel division repeats

Create a stream at the specified channel, of defined rhythm and duration.

• channel: select the channel (1-6) to assign this stream, 0 sets all
• division: set the rhythmic division of a measure
• repeats: set the number of repeats in the stream, -1 repeats indefinitely

JF.NOTE division repeats

Dynamic allocation. Assigns the rhythmic stream to the oldest unused channel, or if all channels are busy, the longest running channel.

• division: set the rhythmic division of a measure
• repeats: set the number of repeats in the stream, -1 repeats indefinitely

Flow

Though streams use division to determine their rhythm, events can be queued and delayed using a division of the master timebase. Using a quantization that doesn’t align with JF.VOX / JF.NOTE’s division of rhythmic streams will cause irregular patterns to unfold.

JF.QT division

• division: 1 to 32 sets the subdivision and activates quantization, 0 deactivates

Think of JF.QT as a performative glue rather than a rigid gridlock. It will slightly affect the timing and ‘swing’ of events. This is especially wonderful when executing scripts manually or with a fuzz-timed source.

Example: JUNG LOVE

Featured in the banner video above.

Geode is set to shape/cycle. IDENTITY through 6N are modulating a resonator (Rings), which is processing (and being sequenced in parallel with) a filtered mix of Mangrove’s Square and Formant outs.

Scripts 1-7 are triggered from the keyboard. Script 7 randomly assigns a velocity between 3V and 7V to 6N.

Teletype’s metronome, which is sequencing the v/8, is bit slower than JF.TICK. JF.VOX commands span even and odd divisions, which JF.QT attempts to wrangle.

Honestly, I’m not even sure what’s really going on here. But it’s fun.
