Voice Allocator / Note Hocketing / Analog Shift Register
Patching is all about creativity. You could simply mult your sequence across your rack or let Shifty spread the notes across time, holding, swapping and routing them. Queue up notes or CV for distribution to up to four modules and dive into the world of hocketing, shift registers and pseudo polyphony.
Shifty is a combination of four sample and hold stages, a sequential gate, and a sequencer controller. This collection of functions allows for some inspiring and useful utility applications, such as clock dividing, or control up to four voices with intricately evolving melodies or chord changes.
Voice Allocation Mode alternately routes incoming CV and gates to up to four voices
Shift Register Mode stores four incoming CV values and sends it to voices sequentially
Choice of four different voice order directions
Pitch outputs are driven by a precision quad DAC to avoid voltage droop
GATE input can be toggled between track or sample and hold
Manual GATE button for sampling/tracking and advancing the sequence
Manual RESET button and jack
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 in the sequence is triggered. Another term for this is hocketing.
The other main application of 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, a clock divider, or as a sequential gate.
TM is a probabilistic random sequence generator based on the research of Alan Turing. His Turing machine was a mathematical model of computation that could, in theory, create any output based on a set of instructions and input variables. In a similar way, the TM chooses random values for steps in a sequence based on the user’s probability settings.
Only available in black. Please send us a message if you’d like to have the module with silver faceplate.
Great space effective unity mixer for audio and cv. Trimpot on the back for gain staging.
Module A-138u is a simple, low-cost mixer with two units. Each unit is equipped with three inputs and one output. The upper unit has for each input a trimming potentiometer available that allows to adjust the amplification in the range 0…+1 for each input (factory setting is 1 for all inputs). The inputs of the lower unit all have the same amplification +1.
The output of the upper unit is normalled to the first input of the lower unit. That way the module can be used also as a mixer with five inputs: for this the inputs 1, 2 and 3 of the upper unit ad the inputs 2 and 3 of the lower unit are used. The sum output for all five signals is then the output of the lower unit. As soon as a plug is inserted into input 1 of the lower unit the module becomes a dual 3-in-1 mixer again.
Inputs and Outputs are DC-coupled, i.e. audio and control signals can be mixed.
Mixer for audio signals, e.g. three VCOs preceding a VCF, when the amplifications are adjusted slightly different no signal extinction occurs during the beat of the VCOs
Mixer for control voltages (e.g. LFOs, envelope generators, random voltages)
