Schmidt Eight Voice Polyphonic Software Synthesizer Now Available


Schmidt Synthesizer has introduced Schmidt Vi, a software recreation of its flagship Schmidt Eightvoice analog synthesizer.

Developed in collaboration with UJAM, the virtual instrument uses detailed modeling of the original synthesizer’s analog signal path to bring its sound architecture into a digital music production environment.

Originally introduced at Musikmesse in Frankfurt in 2012, the Schmidt Eight Voice is a large-format polyphonic analog synthesizer featuring an extensive collection of oscillators, filters and dedicated modulation controls. The instrument was manufactured in Germany using through-hole construction, with an emphasis on long-term repairability.

According to Schmidt, rising manufacturing costs and technological developments have made continued production of the hardware increasingly difficult. The company says it will soon discontinue hardware production, making the introduction of Schmidt Vi a continuation of the instrument’s development in software.

The plugin was developed through a collaboration with UJAM. The original instrument’s analog signal path was analyzed and modeled to reproduce its circuit behavior, interactions and sonic characteristics. An early prototype was demonstrated at Superbooth in May 2026.

Features:

  • Four oscillators, each with a distinct sound-generation character.
  • Oscillator 4 capable of generating complex waveforms through multiple ring-modulation processes.
  • Two Moog-style multimode filters.
  • Two Oberheim-style dual filters.
  • Additional 12 dB low-pass filter at the end of the signal chain.
  • Two parallel filter groups with independent signal-processing paths.
  • 16 LFOs and nine envelopes distributed throughout the synthesis architecture.
  • Frequency modulation, ring modulation and multiple pulse-width modulation capabilities.
  • Dedicated modulation controls located within the relevant synthesis sections, without requiring a centralized modulation matrix.
  • Stereo panning modulation with an LFO for moving sounds across the stereo panorama.
  • Randomizer function for generating new sounds.
  • Parameter value displays that show actual knob positions.
  • Expanded pitch-wheel and aftertouch assignments with multiple modulation destinations.
  • MPE support for compatible MIDI controllers.
  • Multiple plugin instances can run simultaneously, replacing the original hardware’s multimode functionality.
  • Owners of the Schmidt hardware synthesizer can control the plugin using the original instrument’s interface.

Schmidt Synthesizer Schmidt Vi is available now as a software instrument for €179, including applicable taxes. The plugin requires an iLok account and iLok License Manager for authorization.

Krakli Updates Its Free Synthesizer Collection With Mac Support


Krakli has expanded its freeware synthesizer collection to macOS and introduced KXTRA, a new hybrid FM instrument with an expandable operator architecture.

Krakli Software has made a selection of its freeware synthesizer plugins available for macOS, expanding access to a collection that has primarily served Windows music producers for many years. The release also introduces KXTRA, a new hybrid FM synthesizer with a configurable operator architecture.

The updated collection includes Arminator 2026, a revised version of Krakli’s CS-80-inspired synthesizer. The new version features an updated interface, additional functions and a randomization feature.

Other instruments in the collection include RMPX, which combines physical modelling, FM and supersaw oscillator sections; SK7, a synthesizer inspired by classic 1970s designs; XAKT, which combines additive waveforms; and K1Ks, a subtractive synthesizer with three oscillators and two filters.

KXTRA is a separate new instrument. Its operator architecture allows users to add operators according to the available processing capacity of their computer. Each modulation chain feeds its own output stage, effectively providing four separate synthesizer sections.

KXTRA also includes a randomization function designed to generate complete patches rather than simply randomizing individual parameter values.

Features:

  • MacOS versions of selected Krakli freeware synthesizers
  • Arminator 2026, a revised CS-80-inspired synthesizer
  • Updated Arminator interface and additional features
  • RMPX hybrid synthesizer combining physical modelling, FM and supersaw oscillator sections
  • SK7 synthesizer inspired by classic 1970s instruments
  • XAKT additive synthesizer with evolving waveform combinations
  • K1Ks synthesizer with three oscillators and two filters
  • KXTRA configurable hybrid FM synthesis architecture
  • Expandable operator count limited by available CPU resources
  • Four separate output stages for modulation chains
  • Patch randomization designed to generate complete sounds
  • 64-bit Windows and macOS plugin versions

The macOS releases make several older Krakli instruments available to producers who previously could not use the Windows-only versions. The collection also illustrates how independent developers can revisit older plugin designs and adapt them to newer plugin formats and operating systems.

KXTRA represents a separate development from the legacy ports. Its expandable operator structure allows users to build more complex FM configurations according to available CPU resources, while its four output stages provide a way to organize different modulation chains as separate sound sources.

The Krakli plugins are available as free downloads, with optional donations to the developer.

Audio Damage Sandbender, A Four-Operator FM Synth With Wavefolding & MPE


Audio Damage’s new Sandbender synthesizer combines four-operator FM synthesis with wave shaping, wavefolding, extensive modulation, and a low-pass gate, offering a different approach to programming and performing FM sounds.

Audio Damage has introduced Sandbender, a four-operator FM synthesizer that combines frequency modulation with wave shaping, wavefolding, filtering, and low-pass gate processing.

]The instrument takes a different approach to conventional FM synthesizers, adding sound-design and performance features alongside its operator-based synthesis engine.

Sandbender includes ten factory FM algorithms and an algorithm designer that allows users to draw their own operator routings. Each operator can function as both a sound source and a modulator, with tuning options that include harmonic ratios, free ratios, and fixed frequencies.

Beyond the conventional FM architecture, each operator has an independent waveshaper, while additional processing includes a wavefolder, sub oscillator, six noise types, and a stereo filter section. The synthesizer also includes a modeled low-pass gate, offering an alternative to conventional VCA-based amplitude control.

Features:

  • Four-operator FM synthesis with ten factory algorithms and a customizable algorithm designer.
  • Independent operator tuning using harmonic ratios, free ratios, or fixed frequencies.
  • Operator controls include Xmod, Regen, Detune, Spread, and a frequency range from 32′ to 2′.
  • Individual operator waveshaping that morphs between triangle, sine, and pulse waveforms.
  • Wavefolder with symmetric, asymmetric, and soft-clipping modes.
  • Sub oscillator with selectable octave divisions and independent waveshaping.
  • Six noise types: White, Pink, Velvet, Digital, Crackle, and Metal, with additional Color and stereo Width controls.
  • Eleven filter types based on state-variable, ladder, diode, and Sallen-Key designs, with low-pass, high-pass, and band-pass configurations.
  • Selectable VCA and modeled low-pass gate operation, with the low-pass gate linking brightness and amplitude response.
  • Two ADSR envelopes per voice, with adjustable attack and fall curves.
