Game Boy Phrases and RX17 Beats in Synth-Pop | Pi 2025-12-30 by atnr

video upload by atnr

"It is a synth-pop track where RX17 beats are layered with melodic phrases from the Game Boy and phaser-processed electric piano sounds from the OP-1 field.

The Game Boy plays sequences created in LSDj, routed through the ‪@KORG_INC‬ NTS-3 looper.

On the OP-1 field, an electric piano sound is played via the sampler. The sequence is triggered by MIDI sent from Ableton.

The RX17 is also sequenced via MIDI from Ableton, with a light touch of reverb applied using the ‪@strymon‬ blueSky."

Nexus - New Generative Sequencer for Norns // Nymphes // Oto Bim & Boum // Chase Bliss Onward

video upload by Lesjamusic

"Nexus is here. A generative chord-based sequencer for monome Norns that I've been teasing in recent videos.

In this demo, Nexus is driving a Dreadbox Nymphes via MIDI. The signal chain: Nymphes → Oto Bim → Oto Boum → Chase Bliss Onward → Chase Bliss CXM 1978.

Nexus lets you select from a 15-chord diatonic palette while a probabilistic engine triggers notes from within each chord. Two rows on the Grid let you play along in the current scale. There's also bass and sub-bass sequencers that fire root notes on chord changes.

The script outputs MIDI and Crow CV/Gate - so it'll work with pretty much any setup.

Waldorf M 1.11 Update Adds Varysaw VA Oscillator, CS80 Based Oscillator, Extensive FM & More

You can find the update here

Details form the release doc follows:

Disclaimer: This is an unofficial add-on to the M user manual, describing some of extra features added from firmware 1.05 up to firmware 1.11. This add-on also covers some complex aspects of the Multi Mode, which remains somewhat unusual.

Author: Vladi Salnikov aka VladiS.

Algorithms of FW version 1.11:

Varysaw: A VA oscillator ranging from SAW through PULSE to TRI.

Wave (red encoder): Mixes from 0 to 31 from SAW to PULSE; 32 is pure PULSE, and 33 to 63 mixesfrom PULSE to TRI.

Meta parameter: Pulse width for PULSE, adjustable from 5% to 95%.

CSAW: A famous Yamaha CS-80 saw oscillator with mutation towards a parabolic oscillator.

Wave : Controls the amplitude of the “step” component of the saw wave.

Meta parameter: Mixes between this saw wave and the parabolic saw wave.

Waveshpr: A SAW to TRI oscillator fed into a mild waveshaper.

Wave : 0 is pure SAW, 1-62 mixes between SAW and TRI, and 63 is pure TRI.

Meta parameter: Depth of the waveshaper.

TriplSaw: A stack of three SAW oscillators; two are detuned slightly higher and lower than the third.

Wave : Controls the amplitude of the “central” SAW oscillator relative to the two “side” SAWs.

Meta parameter: Detuning factor, from 0 to maximum detune.

S/T Fold: A SIN wave folding oscillator that folds the chosen crossmixed wave between SIN and TRI waves.

Wave : 0 is pure SIN, 1-62 mixes between SIN and TRI, and 63 is pure TRI.

Meta parameter: Folding depth.

FM 2 OP: Classic simple two-operator FM synthesis. OP1 (modulator) generates a sine wave that modulates the phase of OP2 (carrier). Both operators generate sinewaves; the algorithm's output is the carrier signal.

Wave: Maps values from 0 to 63 to harmonics ratios of 1 to 8 in stepped increments.

Meta parameter: Amount of phase modulation applied to the carrier.

Melbourne Instruments Nina | First Patches

video upload by Laboratory 0

"First few patches with the Nina - No external effects."

Melbourne Instruments Nina Round-Robin Experiment #1

video upload by Laboratory 0

"How close can the Nina get to the Vermona Perfourmer? Distributing MIDI notes evenly across three layers on the Nina, each with slight variations in filter and envelope settings. The track, originally made with the Perfourmer (ID: Samuel Yang - Skyward Bound), is now played on the Nina, and I’m amazed by how closely it replicates the original, with its round-robin arps.

Arps coming from Nina, everything else was pre-recorded / taken from the original track."

Yorick LFE firmware Option Pack extra features

video upload by Steve Hunt

"This is an old video I made but never got round to publishing as it was so bad! I've had a few requests about the Option pack, so I'll let this loose now...

This is an add-on firmware upgrade for the Low Frequency Expander for £50. You can see in the Info menu if your LFE has the OP or not.
The Option Pack gives access to additional firmware features:
1. Panel mode that allows the Env/Seq’s knobs to be used to control any device that responds to midi CCs. See Envelope section.
2. An Internal Modulation Matrix lets you set up 3 slots for modulating 29 of the LFE’s internal parameters. 3. A 4th LFO which can be used as a Multiplier for modulating the Amount of the Env/Seq and other LFOs, and can be used as a source to modulate the 29 Destinations in the Internal Modulation Matrix.
4. Fade out time function for LFOs 1 & 2.
5. Polyphonic Aftertouch Destination allowing polyphonic modulation of several synths.
6. Ability to learn modulation Destinations by turning controls on the synth. Briefly hold the appropriate Mult and Dest buttons together to get into listening mode and the Destination is shown as ??????? Now turn a control/button on the synth and the Destination will change to the name of the control you moved."

Whimsical Raps ATRIUM: sound engine exploration (no talking)

video upload by Pete Midi

"Clearly beyond a normal analog synth but I like the extravagant concept and the unique design of Whimsical Raps ATRIUM. Still a few things are missing that hopefully will be implemented in a future firmware update. But, in principle, the ATRIUM has the features that make it a perfect drone and lead synthesizer for me. In this video I just checked the basic possibilities of the sound engine in combination with the user interface elements. I will try out the sequencer options at a later date …

Ambient jam | NDLR, Artemis, Deckard's Dream, Peak, Prophet Rev2, Polymoon, Slöer

video upload by Jay Hosking

"Please support my work on Patreon: / jayhosking
A song performed live on the table with four great polysynths.

It felt like the right time of year to get a bunch of nice synths on the table and just explore. To that end, I connected the Dreadbox Artemis (bass), Sequential Prophet Rev2 (square arp motif), Novation Peak (pad), and Black Corporation Deckard's Dream (melodic motif) to the Conductive Labs NDLR and just had fun. The Artemis and Peak have pretty great built-in effects, but the Deckard's and Rev2 needed some help, so I added the Meris Polymoon to the Rev2 and the Walrus Slöer to the Deckard's.

This was my first time using the new hardware iteration of the NDLR — to be transparent, Conductive Labs sent it over for free — but it was a real step up in terms of the quality of the encoders. And it had been a couple of years since I had played with the Peak, but Novation had offered to send it over to explore, so I said yes to that as well. I previously had a Peak and had missed its effects (especially reverb) and filter.

Once the NDLR is connected and routed to the right MIDI channels, the musical exploration process is extremely fast. I will admit that I usually produce a certain kind of result with the NDLR, and I don't always want that kind of song. But as a palate cleanser, as a way to tap into very fast inspiration, I love putting it on the table and just getting musical results.

Overall, a nice way to end a good year. Thanks for listening.

Performed and recorded live, with EQ, compression, and limiting on the master.

Introducing ADDAC System Servo Controller

video upload by ADDAC System

"At ADDAC we always admired the geniality of Neil Young’s Whizzer, way ahead of its time, a great example of how great ingenuity and engineering can come together to make something great.

Inspired by its motor controlled method we created a standalone solution featuring 8 Servo outputs to control any knob on any amplifier, guitar pedal, rack gear, etc. Bottom line any hardware that has a knob that needs to be controlled/sequenced/automated externally.

The idea behind it was to create a device that would open the possibility to control any knob, any physical knob, be it from a musical device or any other tech appliance that “needs” to be controlled, for musical, artistic or automation purposes.

Our solution comes with a Servo Connector that screws into any compatible physical potentiometer, a coupler connects the motor shaft to the target knob which will turn as the Servo turns.
We use servo motors which can be digitally controlled and move to a precise angle. The motors are controlled by a microcontroller that receives MIDI signals or the internal Expression Pedals and converts these signals to the 270 degree Servo motor range.
Each expression pedal input features 2 knobs: MINimum and MAXimum. These are used to set the range of action of the expression pedal, allowing to dial the range to any sweet spot desired. Raising the MINimum knob above the MAXimum knob inverts the Servo range.

It features MIDI over USB-C, Bluetooth MIDI, and a 3.5mm MIDI IN jack. MIDI can come from any of the 3 sources at the same time as long as they don’t overlap the servos channels being controlled."

Rhodes Chroma Synthesizer, Restored & Upgraded

Note: links to listings are affiliate links for which the site may be compensated.

via this Reverb listing

Video in the listing previously posted here.

"This Rhodes Chromas is in perfect working order, sounds absolutely great, and has been thoroughly updated & reconditioned:

• CC+ Kit Installed – The original CPU board has been removed and replaced with the fabulous CC+ kit. The Chroma CC+ Kit (CPU Plus) significantly upgrades the original Rhodes Chroma synthesizer by adding essential modern features like integrated MIDI, much more program storage (200 programs in 4 banks) instead of the original's limited space, better control over parameters, and expanded MIDI functionality. It essentially modernizes the vintage keyboard, making it fully controllable via MIDI and allowing for complex patch management. It also replaces the original battery-backed memory with non-volatile RAM, eliminating the need to replace the batteries, and removing the danger of battery acid damage.

• MIDI Adapter Included – The Chroma can now send and receive MIDI. With its wooden, velocity-sensitive keyboard, it becomes a fantastic MIDI controller.

• New Power Supply Installed – The original power supply included a large, heavy transformer, and generated a lot of heat. The new switching power supply, designed in Italy specifically for the Chroma, is energy-efficient, reliable, and regulated, ensuring that the Chroma will be stable and noise-free.

• Serviced – All voice cards have had new capacitors installed. All faulty 4000-series logic chips have been replaced, along with several faulty op-amps. Faulty traces and connectors have been replaced.


All voices pass auto-tune test and play perfectly. We’ve burned in the Chroma for 8+ hours and it works perfectly and stays in tune. All keys have been removed and cleaned, and the action feels great. All key contacts have been cleaned and work correctly, with good velocity response.

Cosmetically, the Chroma has some scratches and marks from its 40+ years of use, but overall it’s quite presentable as you can see in the photos.

The Chroma includes the original flight case – however, the foam has gone bad, and has been removed. The flight case would need to be re-foamed to be used to transport the instrument.

The Chroma is available for pickup in Las Vegas, Nevada. We can also personally deliver the Chroma to the Los Angeles, Phoenix, or St. George areas for $150.

The attached video demonstrates the Chroma playing three of the factory preset sounds.

I also have a video showing all 8 voice cards (16 oscillators, 16 filters, 16 VCAs) passing auto-tune without any errors that I can send upon request."
