MNMPatch - Monome Norns Monomachine Patch Randomizer #elektron #monomenorns

video upload by HANJŌ

"I’ve been deep-diving into Elektron gear for a couple years, and recently that obsession has taken on a new shape through coding on the Monome Norns. I wanted to share something I’ve been working on: a patch randomizer for the Monomachine called MNMPatch.

This is about exploring the untapped corners of the Monomachine’s sound engine. I love the unpredictability that Elektron gear allows, and writing this script became a way to extend that philosophy into my creative process. There’s something magical about letting a machine surprise you.

MNMPatch lives on Norns and lets you selectively randomize pages of parameters (SYNTH, FILTER, AMP, etc.), so you can coax happy accidents or just start from a fresh sonic place. It’s already led me to sounds I wouldn’t have dialed in manually, and will become part of my daily jam ritual."

STEREO ENVELOPE FOLLOWER | ADDAC System - ADDAC220 DUAL ENVELOPE FOLLOWER+

"This is our new Stereo Envelope Follower, an analog/digital hybrid for better dynamic range analysis. The incoming audio signal gain can be set with the [GAIN] control, the signal is then fully rectified and passed through an analog envelope follower with a fixed short attack and decay.

This analog signal is then sent into a 12bit ADC (analog to digital converter) of an MCU (microcontroller unit) from here on the signal is processed digitally. Whenever the ADC detects clipping the [CLIP] led will turn On.

The digitized signal is then passed through a Savitsky-Golay filter for noise reduction smoothing the incoming signal. Next the signal is slewed using the [ATTACK] and [DECAY] controls. The MCU keeps a history of the last sampling points and detects the minimum and maximum values of the signal which reflect the current dynamic range and maps the signal minimum and maximum amplitude to 0V and the maximum voltage detected. Avoiding the discharge of the analog envelope capacitor.

This new mapped signal is then processed via the [RESPONSE CURVE] control balacing the response like one would with a standard AD envelope with LOG/EXP control. The [ENV. GAIN] attenuverter control goes up to x2 amplification and sets the attenuation / amplification factor of the output range, the red led monitors this level. The led uses pwm control for faster response and better visualization of the output signal across the full output range.

Finally the [OFFSET] allows to displace the signal’s voltage up or down.

The [THRESHOLD] control sets the level to compare to the output signal and turns the [GATE] output On when the signal is above the threshold.
The [GATE LED] show the output state.
The [CV OUT] carries the Envelope signal (0 to +10V) while the [INV. CV] Output carries an inversion of the signal (-10V to 0v).
The [AVG. OUT] outputs the average of both Left and Right CVs (0 to +10V) while the [INV. AVG.] outputs the inverted average signal (-10V to 0v).
The [STEREO / DUAL MONO] switch allows to use the left channel controls to operate the right channel for stereo operation or keep them independent in dual mono. In Stereo mode only the Right channel gain will be independent.

Left input is normalled to the Right input."

OXI Instruments Unveils the One MKII at SchneidersLaden

video upload by SchneidersLaden

"On March 27, 2025, we welcomed the creators of OXI Instruments for a packed and inspiring evening. The event featured the unveiling of the OXI One MKII, the next-generation performance sequencer, and showcased the Coral, their powerful modular mini-polysynth.

Guests were treated to an in-depth look at the updated OXI One, which builds on the original’s success with expanded sequencing capabilities, improved workflow features, a larger OLED screen, and even more generative and performance tools. The Coral module also impressed with its compact design, full polyphony, and diverse synthesis engines.

After the presentations, visitors had the opportunity to get hands-on with the gear, speak directly with the developers, and enjoy a relaxed evening of music technology exploration. The event took place in our showroom in Berlin-Neukölln and drew a strong crowd of curious synth enthusiasts."
