Notes: A multi-purpose module designed to combine noise and modulation sources, slew, sample-and-hold, envelope following and more. Extremely versatile way to add randomness and controlled movement to patches.

Supplier's Notes:
Flurry collects and connects a number of practical modular synthesis tools, focused on clocks, noises, and randomness to create a module that is rife with opportunities for exploration and experimentation. Equally capable as a synthesis source, modulator, clock, or signal modifier; It is bound to find a way to bring new life and dimensions to your synth patches.

Core Functions:

A clock and random pulse source with adjustable and modulatable rate
Accurate pink and white noise sources
Analogue sample & hold and track & hold circuits with very low droop
Analogue slew with adjustable slew time and edge selection (rising edge, falling edge, or both)
Envelope follower
16 noise synthesis algorithms, each with 2 parameters.

One of Flurry's more interesting aspects is its collection of digital noises, which provide a wealth of interesting noises, suitable for either audio or modulation purposes. Each noise type has its own pair of unique parameters to further dial in the desired characteristics, with the primary parameter under CV control.

Most people consider noise to be "undesirable," and product developers expend great effort to design circuits that minimize noise. So why make a module designed specifically to create noise?

Indeed, unwanted noise is undesirable. But not all noise is unwanted. Synthesizing the sound of wind or waves are a couple of the more obvious uses for a noise generator, but the possibilities go far beyond. The crack of a snare hit; the breathiness of a flute sound; an added sizzle to a resonant pad - all are within the sonic domain of noise.

But noise has many other benefits beyond simply being heard. Noise happens to make a wonderful modulator. When noise is used to modulate a filter's cutoff frequency, or an oscillator's pitch or pulse width, then all sorts of raspy, buzzy, gritty timbres are obtained.

Noise is also a key ingredient in sample & hold circuits - a technique most commonly used to generate stepped, random voltages. The circuit works by sampling an input signal's voltage each time you send it a clock pulse, and holding that voltage until the next clock pulse. So, naturally, Flurry also contains the requisite clocking tools! Two of the most common destinations for the S&H output are a filter's cutoff frequency (creating stepped, clocked timbral changes), and oscillator pitch (which produces random notes at clocked intervals).
Of course, you might not always want your voltages to change so abruptly at each clock pulse. Maybe you'd prefer they wobble about gradually and with more grace? To do that, you need a slew circuit, and once again Flurry has you covered - allowing you to select not just the slew time, but also whether the slew is applied to rising voltages, falling voltages, or both. A flick of the switch, and that Slew circuit becomes an envelope follower, enabling Flurry to generate envelopes from input signals (syncing to drum hits are a common use).

With all these features, plus the ability to create random pulses, clock to external pulses, and perform more esoteric track & hold duties, Flurry is a noise lover's toolbox.

Notes: Noise Random Tools comprises a collection of useful utility blocks that you could use in many of your patches - Clock, Random Pulse, Analog Noise, Sample and Hold, and Slew.

Features:

- Clock and Random pulse source with adjustable rate
- Analog pink and white noise source with very accurate spectrum
- Analog sample / track and hold with very low droop
- Analog slew with adjustable slew rate

Notes: Scales is an 8hp dual-channel note quantizer and step sequencer. Fundamentally, it takes an input voltage, quantizes it to notes in a user-defined scale, and sends that quantized voltage to an output, where you can use it as a melodic pitch source for oscillators or any other module that expects to see discreet note values at its input.

Scales goes far beyond the fundamental, allowing you unprecedented control of the pitches and intervals hiding inside your control voltages; turn LFO's into arpeggiators; random voltages into harmonic counterpoint; and unquantized external CV sequencers into chromatically tuned note sequencers.

Quantization can be locked to an incoming trigger. There are a number of trigger output options as well, ranging from no triggering (good for pitch shifting drones); through triggers that sync with either of the two outputs (or both); to a trigger or gate transmitted in sync with one sent to the module's TRIG input.

Shift:

Scales features two independent outputs, enabling you to create shifted harmonic intervals within your chosen scale using only a single pitch input. Using the SHIFT input you can modulate changes on OUT A and/or OUT B.

You can also use the shift input to switch between scales or to change the root of any existing scale pattern or split Scales into two quantizers - each conforming to a common scale, but fed entirely different voltage sources.

Sequence:

Scales also features a 128-step SH-101 style step sequencer (complete with storage for up to 35 fully programmable patterns) - allowing you to feed OUT B with sequenced notes and rhythm patterns, while OUT A continues to function as a standard pitch quantizer for external voltages. You can even sync the sequencer to quantizer events on OUT A.

Notes: The Shifty is essentially a combination of four sample and hold stages, a sequential gate and sequencer controller. This collection of functions allows for some specific and useful utility application.

One of the primary uses for Shifty is to take a monophonic sequence source and route each new note of the sequence to up to four different synthesizer voices in a specific pattern. In this way you can create pseudo polyphonic sequences since each voice can be triggered to play and sustain while the next voice int the sequence gets triggered. Another term for this is hocketing.

The other main application of the Shifty is to function as an Analog Shift Register. In this mode each new gate input received causes the current set of pitches to be shifted to new output locations as a new one is added and the oldest one is replaced. This can be an interesting way to create chords that are up to four stacked notes when used with a pitch sequence source that has a harmonious series of notes (e.g. a pentatonic scale works really well). Even just using two of the outputs will yield very interesting melodic interplay and is an excellent way to make a simple sequence much more complex and interesting.

In a more basic way the Shifty could be used as a simple Sample/Track and Hold module or as a sequential gate.
