Fixed voltage sources are not a new idea in modular, but we hope that Turn! Turn! brings a new twist to the concept. Turn! Turn! features two independent fixed voltage sources with a useful range of features.Turn! Turn! grew out of a conversation with Steve Levine – when a producer of such note makes a suggestion you have to listen – and act on it. Steve suggested that it would be useful to have a fixed voltage source under the control of a big knob, and the ability to go from as little as 1V over the entire range of the knob. Hence subtle, incremental changes are possible.The final feature set includes a voltage selection switch as well as a unipolar/bipolar switch. Both normal and inverted outputs are included. The following ranges are available from Turn! Turn! depending on switch positions:• 0V to 1V• 0V to 2.5V• 0V to 5V• -1V to 1V• -2.5V to 2.5V• -5V to 5VDIY-Kit-Type:THT-Kit-1.

The MSK 008 Voltage-Controlled Octave Switch is a multifunction voltage processor. The module has two channels, each containing a whole-volt quantizer that maps its input to the nearest integer number of volts from -2 to +2; a three-position toggle switch that shifts the quantizer boundaries up or down by a volt; and a precision adder (with optional subtraction function).If you simply route a pitch CV through one of the unquantized CV1 inputs, it can be a performance control, allowing easy transposition up or down an octave at the flip of a switch. That might be useful for VCOs without their own built-in octave switches. With no input signal, it generates a selectable offset of -1, 0, or +1 volts; feed that into an attenuated exponential FM input somewhere and you get the same tactile control over any other interval transposition you choose.But the possibilities really open up when you start using more inputs. An LFO into the quantized input gives the effect of flipping the octave switch under CV control, keeping your hands free to wiggle elsewhere. Using the unquantized inputs, which are normalled across the two channels, you can transpose one sequence by another. The CV2 input can add or subtract, selectable during build by a solder jumper on the circuit board; in a default build, CV2 adds on the left channel and subtracts on the right, but do-it-yourselfers can change this selection, or design their own expanders to make it switchable on the fly.Combining the two channels, with or without other utility modules, allows more complex melody-shifting effects. And it doesn't have to be just for oscillator pitch control. Switching fixed-voltage offsets on filter cutoffs also makes for great drops and timbral shifts. (And try putting the result through a slew limiter!) The default sum and difference configuration allows the module to act as a "mid-side" encoder or decoder. With other patching it can be a flip-flop or a wavefolder.The MSK 008 is fast enough to work on audio. The quantizer is built from hardware comparators, without a microcontroller, and it can do simple bit-crushing effects across the whole audio spectrum. Each channel can also be a unity mixer for audio, with two regular inputs plus the output of the bit-crusher.Features:• Two channels and multiple CV functions in a small space• Flash-style comparator quantization - no microcontroller• Through-hole design for easy hand construction and maintenance• Connectors between boards, and panel controls mounted on a board - no flying wires• No compromises on build quality: real aluminum panel, not PCB material, with colour printing; nickel and gold plating on the circuit boards; close-tolerance metal film fixed resistors; multiturn trimmers.• Fully open design - no lock-inDIY-Kit-Type:THT-Kit-1.

nQuencer is a Eurorack module that turns the AtoV 16n faderbank into a step sequencer.Connect a 3.5mm stereo cable to the i2c socket, patch in a clock and get a pitch and gate output.When the nQuencer module receives a trigger at the Clock input it reads the state of the first 16n Faderbank fader and outputs a corresponding voltage at Output 1. At the next clock signal it will read the second fader and so on until it reaches the end and loops back to the start.Push the reset button or send a gate to the input to move back to the start.If a fader is at the very bottom no gate will be generated for that step in modes that output gates. The last fader that isn't at the bottom determines the length of the sequence.NOTE: Building the nQuencer module involves surface mount soldering using 0603 components and is therefore not recommended unless you have experience with similar projects. Aside from soldering tools you will require a multimeter to calibrate and suitable equipment to programthe microcontroller if you didn’t purchase one with your PCB.Features:Sixteen steps• up to 16 step sequence• out 1 outputs pitch and out 2 outputs a gate• reset button and input move back to the startTwo Eights• splits the 16n faderbank into two halves each with upto 8 steps• out 1 outputs pitch for the left half and out 2 for the right• clock advances both sequences or reset in advances sequence 2 (alt reset in)Transpose• splits the 16n faderbank into two halves each with upto 8 steps• values from the right half (up to 1v) are added to the left• out 1 outputs pitch and out 2 outputs a gate• clock advances both sequences or reset in advances sequence 2 (alt reset in)DJ• splits the 16n faderbank into two halves each with upto 8 steps but only one sequence at a time• reset button switches the output to the other sequence or reset in (alt reset in)• out 1 outputs pitch and out 2 outputs a gateOptions• hold the reset button to enter settings mode, use the faders to change settings and press the button to exit• direction up, down, up down, random• probability chance of a note firing• output voltage range max 1v, 2v, 3v, 4v• fader at bottom note off, output 0v, last fader not at bottom controls sequence length on/off• gate length• alternative reset input mode on/offQuantizer• root note• scale - chromatic (semitones), ionian (major), aeolian (natural minor), harmonic minor, dorian, phrygian, lydian, mixolydian, major pentatonic, minor pentatonic, blues, disabled (unquantised)DIY-Kit-Type:SMD-Kit-2.
