IM TZ Dual VCO demos

video upload by Todd Barton

"This and other great modules are available at https://www.infinitemachinery.com/

Also, there will be a booth at Knobcon next month https://www.knobcon.com/"

"The TZ Dual VCO is two full featured VCOs on in a single 16HP module. Both VCOs output sine, square, saw, triangle and PWM wave forms. Each VCO also has thru-zero and expotential FM input. The type of FM is selectable using a toggle switch. An important feature of TZ Dual VCO is the FM input for each VCO can be control by a VCA input. A potentiometer adjusts the overall maximum of the FM input while the VCA provides an amplitude envelope.

Each VCO has the following inputs:

1V/Oct
PWM CV
FM signal
FM signal VCA
Each VCO has the following wave form outputs:

Sine
Square
Saw
Triangle
PWM
Each VCO has these adjustment knobs:

Coarse
Fine
PWM
FM amount
The upper VCO can be synced with the square wave of the lower VCO. A three position toggle switch is used to select hard sync (up), soft sync (down), or no sync (center).

Current requirements - 130mA +12V, 130mA -12V"

"Just got turned onto these cool modules from Infinite Machinery which is located here in my little town. Really digging them. Enjoy these brief test drives."

The Infinite Machinery Hexa VCA is a 6 channel VCA with DC coupling and a unique normalization function. All in 12 HP

Signal inputs are DC coupled.
CV input response, 0 to +5V

Maximum amplification is unity gain, or 1.

Channels with no CV input will have CV normalized
to the CV of the channel above. This cascading of CV
values is defined in two groups, channels 1 - 3 and 4 - 6.

For example: If CV is patched to channel 1 and no CV
patched into channels 2 & 3 - Channels 2 & 3 will
follow the CV of channel 1.

Patch CV into channel 2 and nothing into channel 3
then channel 3 will follow the CV of channel 2.
The same hold true for channels 4 - 6, with 4 being
the start of the CV cascade.

Module depth - 34mm

Current draw - 40mA +-

SetonixSynth Marsupial Dual / Stereo VCF for Eurorack - Sound demo

video upload by SetonixSynth

"This demo contains four patches with the SetonixSynth Marsupial configured in four different ways: as parallel (stereo) low-pass, parallel band-pass, series (mono) low-pass and series band-pass.

To showcase the sound of the filter, there is minimal external processing. For the stereo patches the sound source is the Infrasonic Audio Warp Core, while for the mono patches the sound source is a simple sawtooth wave from our Rottnest analog VCO. The Marsupial is being modulated by a single Infinite Machinery ADSR, which is also modulating the gain level through a transparent VCA. No external fx or compression are applied."

Modular DIY 06 - Kassutronics VCO 3340

Published on Jul 17, 2019 Molten Music Technology

"Tackling the relatively simple Kassutronics VCO 3340 kit as supplied by Infinite Machinery. This video turned into a bit of a monster because during the process I ran into trouble testing out a new soldering iron, I had to do my first (and unexpected) bit of SMD soldering, and I had some technical issues. But it was all a fabulous learning experience.
