DIY level: medium. The VCO-1 DIY kit can be built by medium experienced DIYers in about 2-4h. After finishing it, the 1V/oct tracking has to be adjusted, what might need some experience.

The Time Wizard got a bag full of arcane time-warping tricks. All his magical feats are based on 6 dividers with selectable division factors and 4 switches providing 81 routing variations. This module's occult powers have been harnessed to easily clock and reset other sequencers with odd time signatures, provide weird clock division/multiplication ratios, and create complex poly-rhythms.

• Sextuple clock divider divided in two sections A and B
• Dedicated potentiometer acting on the division factor for each divider
• Clock multiplying and weird div / mult ratio abilities for the first section, first section incoming clock can be multiplied by 3 or 4, allowing to get easily triplets from a 16th clock or mult / div association as x4 / 7
• Independant clocking or divider association abilities for the second section, so B5 and B6 can get their clock in internaly from B4. For example, associating B4 = /7 and B5 = /16 provide a hit at each clock begining of 4 bars with a 7/4 time signature
• Auto-reset available for the first section or the whole module, the autoreset is provided by B6
• Additional logic functions for divider A2 : A2 output can provide the following functions : A2 AND B5 or A2 OR A3
• Jumper on the back for Trigger or Gate selection for B5 and B6
• User replaceable firmware chip
• 8hp / 22mm deep
• Power consumption: 20mA @ +12V

Math & Rythm! Two outputs and five different rhythmic flavors multiply by a load of “algo-rhythmic” processing to result in a practically infinite number of polyrhythms. That’s the fundamental formula that produces the Knight's Gallop principle : a dual trigger generator providing sequences according to tables and modes.

• Dual Output Trigger Generator
• Variable length sequences (up to 16 steps)
• Length and Pulse amount potentiometers and CV inputs
• Shift + & shift - buttons allowing to shift the sequence forward and backward
• Main (MN) mode providing a lot of utlity modes for the second output : reset, no shift, invert and reverse
• Compute (CP) mode calculating associated sequences for the second output delivering very musical polyrythm
• Random (RD) mode adding randomness on the sequence feeding the second output, 4 amounts of randomness determined by the sub mode
• Dual (DL) mode allowing to set the two outputs seperatly
• Record (RC) mode turning the Knight's Gallop into a “play your sequence on the buttons and record it” module
• Five different kind of tables for five different rythmic flavours : Classic Euclidean (CE), Revised Euclidean (RE), Erdos Deep (ED), Divide Integer (DI) & Divided sequences (DS)
• User replaceable firmware chip
• 8hp / 25mm deep
• Power consumption: 22mA @ +12V

Basicaly, the Bishop's Miscellany is a dual stepped CV/Gate Recorder. It records two CV’s and two Gates on steps a bit like an analog shift register but with a lot more. First, plug in your CV/Gate keyboard, your MIDI interface, your ribbon, your joystick or your favorite CV/Gate controller and record a sequence. If you are too lazy to play something, you can even use the internal random generator to feed the inputs. Then, play the sequence and mangle it, it's that easy!

• Dual Stepped CV / Gate Recorder
• Variable length sequences (up to 32 steps)
• Shift parameter scanning differents segments in your original sequence.
• AB switch allowing to record two different 32 steps sequences.
• Random value generator very handly to create random loops or to play sequences randomly
• Cut funtion hacking the gate out 1 for more dynamic phrases
• CV inputs for Length and Shift functions • Gate inputs for all the switch functions (Record, AB, Cut and Random)
• 12hp / 22mm deep
• Power consumption: 25mA @ +12V

Mal-2 is a random signal generator mainly intended as CV modulation source. It has 2 modes of operation to provide you with smooth random goodness. Imagine Eris herself lends you a third hand to keep your patches interesting. 1) In the first mode the CHANGE knob morphs from a cubic interpolated (sine like shaped) random signal to a random walk function that could make a wallstreet broker delirious with joy. 2) In the second mode the CHANGE knob sets the self similarity. On the minimum setting the signal is completely random. On the maximum setting the random sequence is locked to a repeating, identical 8 step sequence. In between the sequence seamlessly morphs to new shapes over time. This gives you a random CV where you can shape the bounds in which the chaos unfolds and goes far beyond a slew limited white noise.

Specs:

•     6 HP
•     12 bit CV output
•     through hole components DIY kit
•     Random gate output
•     CV inputs with attenuverter for both knobs
•     super slow cycles times up to lower audio range
•     +12V 60mA | -12V 5mA

The 2M is a dual three channel mixer in 6 HP with volume controls over all the inputs as well as the final output. As its design has been specially focused on audio applications, the input potentiometers are audio-taper type while the output ones are linear. Low distortion / high quality audio operational amplifiers have been selected in order to achieve clean audio mixing, but is also DC-coupled, so it can perform CV signal mixing as well. Great for a small system, allowing for submixes or even stereo mixing.

The Zlob Modular Attenumixer is a skiff friendly three channel passive attenuator with a sum. Each channel is normalled to the sum (VI) so it can be used as a 2 channel mixer and 1 channel attenuator, or a 3 channel mixer, or as 3 separate attenuators. Normalization to the sum is broken by inserting a jack into the outs of channels I-III. The Attenumixer works well with both CV and audio, although the potentiometers have a linear response. Since this module is passive there will be some amount of signal loss with the sum out. No power consumption, it's passive.
