Morpheral Machines Introduces The Swarm, A New Approach To Wavetable Synthesis


Morpheral Machines, a new software instrument developer founded by Renoise creator Eduard Müller, has introduced The Swarm, a polyphonic wavetable synthesizer built around a different approach to oscillator behavior.

The Swarm, a wavetable synthesizer that uses up to 24 independently moving oscillators per voice. The new instrument combines flocking behavior, extensive modulation, and evolving wavetable textures.

Rather than using conventional wavetable playback, The Swarm generates each note using a group of virtual ‘birds’, called ‘boids’, with each boid controlling its own wavetable oscillator. The boids move across a two-dimensional grid of single-cycle waveforms, with their individual positions determining the waveforms being played.

The movement of these oscillators is governed by flocking behavior. Each boid responds to its neighbors and the surrounding environment, producing groups that can move together, spread apart, or follow different trajectories across the wavetable grid.

The result is a synthesis engine in which the movement and organization of the oscillators become an integral part of the sound.

The Swarm supports between one and 24 boids per voice, with up to 12 voices of polyphony. An attractor can guide the flock’s movement, while up to nine predators can disrupt its formation. Twelve different attractor types are available, with movement that can operate freely or synchronize to the host tempo.

The synthesizer’s wavetable editor uses a grid ranging from 3 x 3 to 13 x 13 single-cycle waveforms. Users can draw waveforms directly onto the grid, morph between them using six different methods, or import WAV, FLAC, and WT wavetables.

The software can also analyze audio files and recordings, extracting their most distinctive cycles and arranging them across the grid so that similar waveforms are positioned near one another.

The Swarm also uses the behavior of its oscillators as a modulation source. Each voice measures characteristics including flock alignment, separation, distance from the attractor, and position on the grid. These parameters can be routed to other synthesis functions or used to influence the flock’s behavior.

The instrument includes 32 modulation routings per voice, with 17 modulation sources and 28 destinations.

Features:

  • Up to 24 band-limited wavetable oscillators per voice, each with its own optional FM modulator.
  • Polyphonic operation with up to 12 voices, including mono and legato modes.
  • Flocking behavior in which individual oscillators respond to neighboring oscillators and their environment.
  • 12 attractor types for controlling oscillator movement, with free-running and tempo-synchronized operation.
  • Up to nine predators that can disrupt the formation and movement of oscillator flocks.
  • Two-dimensional wavetable grid with between 3 x 3 and 13 x 13 single-cycle waveforms.
  • Waveform editing with direct drawing and six different morphing methods.
  • WAV, FLAC, and WT wavetable import, with the ability to generate waveform grids from audio recordings and samples.
  • 17 modulation sources and 28 modulation destinations, with 32 routings per voice.
  • Flock-based modulation sources including alignment, separation, distance from the attractor, and X/Y position.
  • Sub oscillator and white, pink, and brown noise generators.
  • Five filter models, including state-variable, Sallen-Key, OTA, transistor ladder, and diode ladder designs.
  • Waveshaper with soft and hard clipping, sine and triangle wavefolding, and pitch-locked crushing.
  • Tap-cloud delay with eight independently moving delay taps per voice, capable of producing chorus, echo, and reverb effects.
  • Seeded randomness with four independent seed domains and options for resetting random behavior on the first note, every note, or with the host transport.
  • MPE, CLAP, and VST 3 note expression support, along with MTS-ESP microtuning.
  • Approximately 50 factory presets covering basses, keys, leads, pads, and other sounds.

Morpheral Machines The Swarm is available now for Windows, macOS, and Linux in VST 3 and CLAP formats, with AUv2 support for macOS. The software supports native Apple Silicon processors.

The introductory price is $59 / €59 through November 30, 2026. After the introductory period, the regular price will be $79 / €79.

Free, Open-Source OpenRB-338 Brings ReBirth Back For Modern Computers


OpenRB-338 is a free, open-source reimplementation of Propellerhead’s ReBirth RB-338, bringing its combination of two TB-303 basslines and TR-808 and TR-909 drum machines to modern macOS, Windows, and Linux computers.

Originally released in 1997, Propellerhead ReBirth RB-338 combined software recreations of classic Roland instruments into a streamlined virtual studio.

OpenRB-338, a free and open-source application developed by pingw33n, recreates ReBirth for current desktop operating systems, with an audio engine designed to reproduce the original software’s output.

The project also supports original ReBirth song files and provides tools for working with the format.

Features:

  • OpenRB-338 recreates the original ReBirth configuration, including two TB-303-style bass synthesizers, a TR-808 drum machine, and a TR-909 drum machine.
  • The audio engine was rebuilt based on ReBirth 2.01 to provide bit-accurate rendering. The project documentation describes byte-for-byte comparisons against the original software’s exported loops, tested against a collection of more than 1,200 songs.
  • The interface brings the complete virtual studio onto the screen, including the four instruments, mixer, delay, distortion, PCF filter, compressor, pattern and song modes, shuffle, loop, and recording functions.
  • A scalable vector-graphics interface keeps the control panel sharp at different window sizes and display resolutions.
  • OpenRB-338 can open ReBirth 2.x song files in RBS versions 4.0 through 4.2, as well as ReBirth 1.x songs. It can also save RBS 4.2 files that can be opened by the original ReBirth software.
  • The application supports ReBirth modification files, allowing users to load alternative drum samples and associated mod sounds. The standard drum kit is included, so the original installation media is not required for that kit.
  • Audio loops can be exported in WAV, FLAC, and Ogg Vorbis formats.
  • The project also includes a command-line application called orb. It can render songs to audio files, play songs without the graphical interface, inspect song information, and unpack, repackage, or re-encrypt modification files.
  • OpenRB-338 is distributed for macOS on Apple Silicon and Intel processors, Windows on x64 and ARM64 systems, and Linux on x86_64 and ARM64 systems.
  • The source code is published under the GNU General Public License version 3.0. The developer states that OpenRB-338 is an independent project and is not affiliated with or endorsed by Propellerhead Software or Reason Studios.

*Note: The software is a standalone application. The project’s documentation currently lists MIDI input, MIDI synchronization, VST, AU, and ReWire support as unimplemented. It also notes that some original pattern-editing functions and undo are not yet available.

OpenRB-338 is available now as a free, open-source download.

MicroMonsta 2 Firmware 3.0 Adds Polyphonic Aftertouch & Expanded Chord Tools


AudioThingies has released firmware 3.0 for the MicroMonsta 2, a bi-timbral digital synthesizer, introducing a substantial collection of performance, sequencing and sound-design improvements.

The update adds polyphonic aftertouch support, allowing individual notes to respond independently to pressure when used with a compatible controller. Presets configured for aftertouch will respond to either channel or polyphonic aftertouch without requiring additional configuration.

The synthesizer’s internal keyboard, scaler and chorder have also been redesigned. The updated system offers 21 scales and 63 chord types, including different three- and four-note voicings. Users can assign different chord types to individual notes within a scale, with keyboard, scaler and chorder settings now saved independently with each preset.

Firmware 3.0 also expands the MicroMonsta 2’s modulation capabilities. A second 16-step modulation sequence synchronized to the arpeggiator has been added, along with two additional modulation matrix slots and new destinations for effects, envelopes, oscillators and arpeggiator parameters.

Other changes include revised filter resonance behavior, an updated soft-clipping algorithm, expanded oscillator tuning and a new Scale mode designed to prevent parameter values from jumping when turning the synthesizer’s encoders.

Features:

  • Polyphonic aftertouch support allows individual notes to respond independently to pressure from compatible MIDI controllers.
  • Presets configured for aftertouch respond to either channel or polyphonic aftertouch without requiring additional configuration.
  • Redesigned internal keyboard, scaler and chorder are now available in all operating modes, including MPE mode.
  • The updated scaler offers 21 musical scales and 63 chord types, including 27 three-note and 36 four-note voicings.
  • Chord selections include open triads, suspended chords, sixth-ninths, extended shells, rootless ninths, thirteenths, fourth and fifth stacks, and clusters.
  • Different chord types can be assigned to individual notes within a selected scale, allowing each note to trigger a different voicing.
  • The internal scaler and chorder can also be played using incoming MIDI notes.
  • Keyboard, scaler and chorder configurations can now be saved individually with each preset rather than being shared globally.
  • A second 16-step modulation sequence has been added, synchronized to the synthesizer’s arpeggiator.
  • Each modulation sequence step can generate low, mid, high or random values, with unipolar or bipolar output available.
  • The new modulation sequence can affect an entire program or individual generated notes.
  • The modulation matrix has been expanded from 10 to 12 slots.
  • New modulation destinations include delay time, feedback and level, reverb level, envelope sustain, oscillator shape and arpeggiator gate time.
  • Arpeggiator gate-time modulation can create overlapping notes for legato slides.
  • A new Scale mode for the synthesizer’s encoders prevents parameter values from jumping when a control is turned. Jump mode remains available as an alternative.
  • Filter resonance behavior has been revised, with consistent self-oscillation levels across the frequency range and additional low-pass filter self-oscillation behavior.
  • Two filter response modes, MM2 and VNT, replace the previous Soft, Mild, Hard and Mean resonance modes.
  • The soft-clipping algorithm has been updated to provide a more analog-style response.
  • Coarse tuning ranges for all three oscillators have been expanded from -24 to +12 semitones to -24 to +24 semitones.

MicroMonsta 2 firmware 3.0 is available as a free update for existing owners.
