PM Foundations Variable Filter Bank no. 3

video upload by Randy Piscione

"This is demo number 3 of the PM Foundations Variable Filter Bank. This is a two part video, starting with using one module animated by four LFOs (at 0:00), followed by two modules animated by eight LFOs in stereo (at 3:56). The second part really needs headphones."

Max Support for Melbourne Instruments Roto-Control (Setup Guide)

video upload by Cycling '74

"We are excited to announce that Melbourne Instruments’ Roto-Control now integrates natively with Max, giving you a powerful tactile interface for building and performing with your Max patches.

With Max supported directly in PLUGIN Mode, Roto-Control can control custom instruments, audio effects, MIDI processors, and performance tools created in Max. Motorized knobs, touch-and-learn mapping, and haptic feedback make it easy to map parameters, recall states, and interact physically with your patches.

This setup guide walks through how to install the Roto-Control package in the Max Package Manager and connect the hardware so you can start controlling your patches right away.

Iridium Desktop MK2: The Next Sound Dimension

Iridium Desktop MK2 is a new generation of the highly acclaimed Iridium Desktop synthesizer introduced in 2020 by Waldorf Music, and since then used by countless artists and sound designers. After six years the time has come to advance the sonic success story even further.

Based on the legendary multi-engine design of the Quantum & Iridium product line, the MK2 innovates even further, thus fitting perfectly into Waldorf’s forward-looking synthesizer design philosophy.

The MK2 features a new and fresh design, and an improved CPU board with more RAM and flash storage allowing for more sample storage and opening a whole new world of synthesis capabilities.

Per-Note-Parameter-Locks
(ft. Aphex Twin)
Only on the MK2 you can enjoy a very special feature called Per-Note-Parameter-Locks which is the result of a collaboration with legendary Aphex Twin, a long-term Iridium Desktop user.

With this feature, each of the 128 notes can be assigned up to 16 individual parameter variations by simply holding a note and turning knobs. This system allows each note to have a different set of parameters. You can even change the synthesis mode of oscillators for each note or change effect parameters. It feels like adding a whole new dimension to your music. Per-Note-Parameter-Locks are saved with each patch and can be inspected and edited on a dedicated page.

Seeds – The Sixth Synthesis Sense
The added RAM further allows a new sixth synthesis method for each of the three oscillators. Inspired by wavetable synthesis, in which each wavetable represents a timbral journey, Waldorf has found a way to base these timbral journeys not only on static waveforms, but also to dynamically synthesize each waypoint from sub-oscillators we called “Seeds”. These can be controlled and recombined using techniques like ring modulation and frequency modulation, and enriched with noise and other non-pitched material. While we provide, similarly to wavetables, a set of predefined timbral journeys, you can also edit and create your own.

Protein’s “Flavour” Knob
The new knob called “Flavour” adds sonic liveliness using our new concept of micro-variations in timing, timbre, pitch, and a whole set of additional parameters we recently introduced with the Protein synthesizer.

More Memory, Layers & Sound
With the increased memory capacity, you can change the multi-timbral layer count from 2 to 4. In addition to layered and split modes, the new MK2 also features more advanced multi-timbral modes, such as round-robin and random-robin. These additions bring greater timbral richness and variety, letting you build deep and complex sonic landscapes. A dream come true for all sound designers, sonic explorers and cinematic artists!

Iridium & Quantum Update 4.0
A general update of the Iridium and Quantum operating system will be available soon.

Version 4.0 provides some of the new features for all existing Quantum and Iridium models like the Mutator patch randomizer introduced in the Microwave plugin, a new polyphonic arpeggiator, new microtonal features saved in patches and other features.

Stereo Audio Out: 2x TS jacks
Stereo Audio In: 2x TS jacks

RetroSound Studio Tour: Vintage Hardware Sampler from the 80s

"RetroSound Studio Tour: Classic Hardware Sampler from the 1980s

In this episode of RetroSound Studio, I explore legendary vintage hardware samplers that shaped early digital music production. From professional 8-bit and 12-bit studio machines to iconic toy sampling keyboards, these instruments defined the sound of 1980s electronic music, hip-hop, experimental, and synth-based production.

The E-mu Emulator II became one of the most iconic 8-bit samplers ever produced, known for its warm analog filters and unmistakable character. The E-mu Emax brought professional sampling to more studios with its gritty 12-bit sound. The PPG Waveterm, paired with the PPG Wave system, represents one of the earliest digital sampling and wavetable workstations in synthesizer history.

On the experimental side, the Casio SK-1 and Yamaha VSS-200 introduced affordable lo-fi sampling to a generation of musicians, becoming cult classics for their crunchy digital tone and creative limitations.

These vintage samplers shaped genres such as synth-pop, early hip-hop, industrial, experimental electronic music, ambient, and film scoring. Today, they remain highly sought after by producers and collectors researching vintage hardware samplers, 80s sampling technology, Emulator II sound, Emax workflow, PPG Waveterm history, and lo-fi sampling keyboards.

If you are interested in classic digital sampling, early electronic music production, or rare retro studio gear, this RetroSound Studio episode offers an in-depth look at some of the most influential samplers ever built."
