Making Pinged Kick Drums with Toppobrillo Multifilter 2

video upload by Travis Kennedy

"*HEADPHONES OR HIGH QUALITY SPEAKERS RECOMMENDED*

How to patch a kick drum with the Toppobrillo Multifilter 2:

1. Patch a gate or trigger to the Ping input of the filter. You can monitor any output but I use the Variable mode output.

2. Set the resonance to at least 12 o’clock but no higher than 3 o’clock. More resonance = more sustain

3. Set the frequency below 10 o’clock or to taste.

4. Patch either the low pass, band pass, or high pass outputs to the Mode CV input. Attenuvert to taste. This can add some phase modulation and increases harmonics.

5. Send a decay envelope to the FM input. Attenuate to taste.

6. Ignore the filter inputs and gain knob.

Notes:
Envelope generated from a Toppobrillo Sport Modulator 2 with a linear shape.
I prefer taking the output from the Variable output because of the additional tone shaping available, but you can use any output for this patch. It can also be fun to experiment with using multiple outputs and processing them differently."

"Cluster is our take on the workflow of the versatile Buchla 200 series control-voltage processor- model 257- with some marked improvements and options. Missing is the cool equation, but we kept some arrows and replaced the variables with LEDs :) We've also added a voltage-controlled “polarizer” (4 quadrant multiplier), an extra processing / mixing channel and routing options that make it an extremely flexible and more compact tool for the dense Eurorack environment..

Cluster is a precision 8HP processing toolbox that can sit anywhere in a system. It has 3 independent sections that can be used individually or taken as a whole. Up to 4 signals can be mixed and there is also a complementary sum output. Potentiometers are center-detented for easy tactile centering. Signal path is high bandwidth, low noise and low offset- and is well-suited for both audio and control signals.

Each section can be used independently vis-a-vis independent outputs and a subtractive normalization scheme- This means if you need to grab a crossfader (or just use it as a VCA/ ducker) it’s there, and you’ve still got the polarizer (XY) and another processing channel (Z) mix to work with.


XY (polarizer channel)
The top section is a voltage-controlled “polarizer” or more accurately, a four quadrant multiplier.. It multiplies two signals, “X” and “Y” . The X(Y) output is the product of these two sources. Unpatched, the Y input is normalized to an offset voltage, and thus will act as a standard processing channel when unpatched, giving X*1 when fully CW and X*-1 fully CCW. Patching a source into the Y INPUT defeats this normalization, and the “Y AMT” knob will now scale (multiply) the source patched into Y, giving Y*1 when fully CW and Y*-1 fully CCW. This is useful in that it allows the top section to be easily patched as a standard VCA with a positive going CV. A bicolor LED indicates output amplitude and polarity.

A->B (crossfader channel)
The middle section is a linear crossfader. The knob and A->B CV input sum, and select A to B and anywhere in between.
The ‘REF’ toggle, when engaged, routes a selectable offset to INPUT A’s normalization- This allows you to use the crossfade channel as a voltage "mirror", for instance. LEDs indicate the relative crossfade position.

Z (attenuverter/ offsetter channel)
The bottom section is simply another processing channel with an offset normalled to it’s input, acting as a manual offset control when unpatched. Patching into Z defeats this normalization, and Z AMT knob will now multiply the Z input, giving Z*1 when fully CW and Z*-1 when fully CCW. A bicolor indicates output amplitude and polarity.

SUM OUTPUTS
There are two SUM outputs, “∑” and the complementary “-∑” . The SUMs are a summation of the three processing sections. Patching any of the three sections’ outputs independently removes them from the SUM outputs. This scheme allows for flexibility using the channels independently, for example, using Z as an offset voltage someplace in a patch- as well as prevents loopback issues when patching Cluster back into it's self- if, say, for instance you wanted to use XY as a ring-mod and send it to one of the crossfade inputs to have a VCA'd ring-mod, or vice-versa, you won't be adding XY to the SUM twice."

Toppobrillo Multifilter 2 Eurorack Filter Demo

video upload by Travis Kennedy

"The Multifilter 2 is a redesign of Toppobrillo's state variable filter from the previous decade. This filter design provides a 12db/oct LP and HP plus a 6db/oct BP and Notch filter. New to this version is a dual input with manual crossfading, dedicated Ping input, and a variable mode output with CV control and switchable filter frequency tracking. There is also a jumper on the back panel for soft clipping on the input circuit (which I use throughout this video).

"To those who purchased the limited edition Pink Loquelic Iteritas, thank you. The module sold out swiftly, and net proceeds from the sales went to parrot conservation with Macaw Recovery Network.

This jam features many Eurorack modules, but we thought the standouts were the Pink Loquelic Iteritas oscillator, Virt Iter Legio stereo oscillator, Mimetic Digitalis CV sequencer, and the Librae Legio dynamics processor.

Non VCO VCOs

Published on Jan 14, 2018 Randy Piscione

"Using a pair of function generators as VCOs, there are no standard VCOs in this video. Everything is driven from a Eurokorn sequencer, bass is one side of a Random*Source Smooth/Stepped Generator, 'percussion' is the other side. There are two noodles, from two sides of a Buchla/Toppobrillo Dual Function Generator.

A few filters are called in to add some randomness and the only other modules are utilities, such as VCAs, LFOs, EGs and mixers."

"Excellent, fully functional, Buchla designed Dual Function Generator in Eurorack format w Grayscale Panel. Includes excellent Manual Trigger Modification allowing self triggering. These Dual Function Generator PCBs were created by Toppobrillo using the original Buchla 281 schematic. It's exactly 1/2 of a Buchla 281. This is basically the same circuit used in the Make Noise Maths, and the implementation is pretty close, although the Grayscale Panel footprint is considerably smaller, at 16HP (versus 20HP for Maths). Photo is of actual module, and comes with original blue Buchla 200 knobs."

Vermona PerFourMer Analog Chords

Published on Nov 24, 2015 SGE

"The PerFourMer excels at chords. Using the 4 CV inputs I made chords using a Toppobrillo Quantimator which was driven by a Korg SQ-1. The 4 triangle waves of the PerFourMer are slightly panned to sound nice and wide, then effected by a Roland RE-20 reverb and delay. The Microbrute plays a sequence which is ping-pong delayed by a Disting module (in delay mode) and Doepfer panning module. Drums are custom samples from an Electribe ESX-1 (offscreen)."

The addition of an illuminated pushbutton switch add to the overall module's 'playability'."

"Dual 281 Function Generator w/LED trigger switch mod (Eurorack)

The Dual 281 is an ASR/AR/LFO generator with voltage controlled inputs for Attack and Decay. This essentially half of the original Buchla 281 but designed for Eurorack Format modular synths. Make Noise's Maths was designed to mimic the 281 and Serge's Dual Universal Slope Generator. Several of these were built for a non-paying customer and now just trying to recoup costs on this last one. These were built with grayscale panels using Toppobrillo PCBs and offered to the DIY community. Wima caps used throughout with the exception of the 1.8nF film caps (Kemet). NKK switches long life switches, long life and low ESR caps for power decoupling. Blue LED switches allow for playing the module in real time...The FG can be triggered by finger. Check the vids. These were only mounted in a lab case and burned in for extensive testing."
