Modcan Quad LFO Eurorack Module

via this auction
"The Quad LFO is a versatile and powerful source of modulation waveforms that will extend the modular LFO well beyond simple vibrato.
The Quad LFO has 16 wave types to choose from including various random waves and morphing wave sets which are actually 32 waves with smooth morph transition with the potential for thousands of different shapes. Each of the regular waves employs some form of real-time waveform transformation. For example the Sine wave can smoothly transform into a triangle wave, The stair case wave can change the number of steps on the fly, the Random wave has built in slew for smoothing, The pulse wave has variable width (PWM) etc. Please take a look at the animated gifs to see all the possible wave transforms possible.
Each of the 4 LFOs can function independently with separate control over frequency , amplitude, waveform selection, waveform transform, and CV routing. Each LFO becomes "live" for editing when selected using the 4 way rotary switch. All knob and switch settings are saved in EEPROM for later power up.
There are over 200 possible switch combinations per LFO providing a huge degree of flexibility when using all 4 LFOs. Each LFO has an accompanying GATE and CV input. The Gate is used for RESET and sync functions while the CV input can be routed to any or all of the frequency , amplitude, waveform selection and waveform transform functions for modulation of parameters.
While each LFO can operate independently there are also modes which extend the module in ways that make it truly unique.
QUADRATURE MODE converts the Quad LFO to a single LFO but with quadrature outputs spaced 90 degrees apart. This feature in itself is not radically new but the ability to have quadrature waveforms OTHER than sine shape is. Here we have all the waves available in quadrature including random and morphing waves for advanced quad panning or barberpole type effects.
PHASE LOCK mode in another unique feature of the Quad LFO which synchronizes the phase of all 4 LFOs waveforms but allows the frequency to be a division of the master LFO 1. This is a great way to generate complex drum sequence rhythms using the PATTERN wave.
ROTATE MODE functions like an electronic switch with a gate/clock applied at GATE1 the 4 LFO outputs rotate 1 step to the right wrapping 4 to 1 with each new pulse. Each LFO is independent in its settings only the outputs change order. Great for creating unusual or unpredictable modulation shapes.
The GATE section has a number of unique features for an LFO.
RESET mode does what it says. When a gate pulse is received at the gate input jack the LFO waveform resets to zero like a hard sync function on a VCO.
RSTST or Reset Start mode performs similarly to RESET mode with the added bonus of allowing the user to set the waveform start position using the Reset Knob or CV.
HOLD mode freezes the LFO when the gate input is high.
SYNC/TAP mode uses the gate pulse period to set the frequency of the LFO. This is a great feature for synchronizing the LFO to sequencers etc as an auxiliary event generator and for creating unique CV patterns. The TAP button can also be used instead of the gate jack to manually set the LFO frequency. In sync mode the frequency can also be set to division of the input gate/clock from 1-16 including odd number divisions like 3,5, etc.
Features
4 Independent LFOs
Low and high frequency ranges. Low range is .003Hz-51Hz
High range is 16HZ-1.6kHz and can be used for audio
Real-time CV control of Frequency, Amplitude, Wave Morph and wave selection
Output choice of 0 to +5V, +/-5V and inverted version of both
16 bit 48kHz sample rate means super smooth waves with no quantization stepping
Memory storage of all settings between power cycles
100s of button combinations for massive flexibility
Unique waveforms like cosine random and stair case waves
Smooth wave morphing in TABs 1-3
All waves employ some form of transformation wave shaping
Uses a paltry 40mA of current on the +12 rail and 10mA on the -12V rail
18HP wide shallow depth approx 1"

Modcan Dual Freq Shifter Eurorack Module
Note: Auction links are affiliate links for which the site may be compensated.
via this auction
"The Dual Freq Shifter is an all digital interpretation of the classic Bode design with numerous significant benefits over its analogue predecessor, primarily the dual configuration.
There are probably only a handful of vintage Bode FSs in the hands of users that are ever within factory specs at any given time due to complicated and costly calibration procedure. With the Dual Frequency Shifter calibration will never be an issue and will remain an accurate and precise instrument regardless of ambient temperature or age.
Frequency shifting is primarily a mathematical function and nothing does maths better than a DSP capable microprocessor. No analogue circuit comes close for feed-thru error free multiplication, high image rejection and VCO stability.
Another important consideration is that it would be both cost and space prohibitive to implement a matched set of dual FS in analogue with similar features and performance especially in 12HP.
The real fun begins when the two independent FS sections are patched in series or as independent stereo processors. This allows for some seriously altered stereo effects with near 3D results.
Features
2 independent Frequency Shifter channels in one package
CV control of feedback for each channel
CV control of Shift for each channel
Clip indicators
+/-5kHz Exponential Shift range
+/-5kHz Linear Shift range
Thru-Zero operation
High Quality Codec
16bit Audio
Zero calibration maintenance
20Hz-20khz response"
