"Butterflies, bats, 16mm swarm: Gieskes Klok modulates itself and No Drum and Olivia Artz Modular Uncertainty, which modulates No Drum, while Klok gates No Drum."

This appears to be the first post to feature Olivia Artz Modular. Details on their modules follow via Perfect Circuit and Noisebug.

"Uncertainty from Olivia Artz Modular is a 2hp coin toss module; it is open source, with new, user-swappable firmware being developed. So, it will continue to grow and offer new functionality!

In the standard firmware, the top input accepts gates, triggers, or any signal between -5V and +5V. Based on whether the input is positive or negative, it uses two different types of logic to produce gates at the corresponding eight outputs. If the input is above +1V, then the module does eight differently-weighted "coin tosses"—one for each output. If the outcome of the toss is "heads," a +5V signal is output for as long as the input stays above 1V. If the input signal is -1V or lower, a slightly different coin toss algorithm is used, where the outputs are paired—if the result of the toss is "heads," the upper output of the pair in question sends out a signal, and if it's "tails," the lower outputs sends out a signal.

Alternate firmwares are available for free, and loading them is as easy as plugging in your module via the rear PCB USB connection, dragging on a file, and you're done. The first new official firmware is a VU meter—with the panel LEDs displaying the current voltage level, and each LED getting a dedicated gate output—somewhat like a multi-window comparator! Olivia Artz's Uncertainty module is a great way to add chance operations to your rack without sacrificing space.

Explore the sounds of temporal experimentation with Time Machine from Olivia Artz Modular, an eight-tap stereo granular delay module. Providing nine faders for tactile control of each delay line (plus the dry signal), Time Machine offers a canvas with which to bend and shape delays for a variety of sonic results. With an immediate interface perfect for performance, and precision capable of tuned feedback tones and polyrhythmic delay patterns.

In addition to the generous array of delay lines with dedicated faders, Time Machine is equipped with even more controls for designing delays. The t knob sets a maximum delay time up to 8 seconds. This physical control is exponential, providing ample room to explore short delay times. For astronomically long delays, the t/2v CV input controls maximum delay time up to 2 minutes and 30 seconds, with each 1V of change resulting in a doubling or halving of the delay time. Adding further options for your sound design, a clock input allows you to create rhythmic delays related to the clock tempo, spiraling simple sequences into complex and captivating polyrhythms. Spread control and CV input tilts the spacing of repeats towards or away from the maximum time value (t), providing a way to unquantize delays and shape the timbre of reverb-like effects. Finally, a feedback control and CV input allows more of the processed signal to return to the delay, dialing in everything from slap-back effects to screeching granular feedback drones.

Time Machine excels at creating warm feedback plucks, rhythmic and ratcheting repeats, and infinitely echoic granular goo. Its wide range of sonic possibilities are easily explorable through a straightforward interface that rewards tactile experimentation and play. Comprehensive enough to be your only delay and plenty of character to stand out in a dedicated effects rack, Time Machine from Olivia Artz Modular offers a future worth exploring.

"Teletouch is an expressive performance instrument designed primarily for the Monome Teletype and Norns systems.
Inspired by the long history of touch plate surfaces in synthesis, Teletouch finds ways to add gesture and manual control to modular instruments.

An all in one human interface, the copper touch plates output both note and pressure information, over both I2C (duophonically) and USB MIDI (fully polyphonically), the 8 buttons allow for mode-switching, event triggering and midi note drones, and the 4 knobs and 6 sliders add midi cc output and physical control over teletype variables, making Teletouch a natural centre of control in your system.

While over MIDI, the keypresses and cc messages are fairly pre-defined, teletype can be processing I2C messages in a whole range of ways! Try using the sliders to define values in a 6 step sequence. Use the key pressure value to control the rate of a clock! Use the touch plates to jump between different sets of sequenced patterns! Teletouch turns teletype into an incredibly performable device.

While Teletype and Norns were the primary inspiration for Teletouch, its I2C outputs can be read by any I2C host, such as monome crow, which expands possibilities further to interaction with Cycling 74’s Max MSP, while its behaviour as a class compliant USB device lets all its knobs, buttons, sliders and touch plates work perfectly with any computer or other midi host.

Please note: while Teletouch has gate outs, it is not designed for direct intergration as a cv controller. These gate outs are instead there to be patced directly into Teletype trigger inputs.

Anyone with a Teletype will know that the constant fast polling necessary for an I2C device to trigger note on messages is unviable. Teletouch gets around this by providing physical triggers. When a keypress is detected, Teletouch will physically trigger a Teletype script, which can then immediately read the note value of Teletouch. This way, Teletouch can be extremely responsive, even over I2C."
