Different Instruments Introduces Free Physical Modeling Synthesizer, PartialString, For macOS, Windows + Linux


Different Instruments has introduced PartialString, a physical modeling synthesizer that generates sound by numerically solving the one-dimensional wave equation in real time.

Rather than relying on sampled sounds or traditional virtual analog oscillators, the instrument represents a vibrating string as a series of displacement points and computes the propagation of energy across the string. A virtual pickup measures the string displacement to generate the audio output.

The instrument supports up to 10 voices of polyphony, with the available voice count adapting dynamically according to CPU performance and the simulated string lengths.

Features:

  • Finite-difference time-domain (FDTD) physical modeling synthesis engine
  • Real-time numerical solution of the one-dimensional wave equation
  • Models the vibration of a plucked string as a displacement grid in memory
  • Virtual pickup generates audio by measuring string displacement
  • Supports up to 10-voice polyphony
  • Dynamic voice allocation adjusts polyphony based on available processing power and simulated string length
  • Adjustable excitation position along the string
  • Adjustable excitation shape
  • Velocity-sensitive excitation
  • Pickup position is continuously adjustable
  • Pickup position can be modulated by an LFO
  • Pickup LFO operates up to audio rates for AM-like sidebands
  • Adjustable string decay
  • Dampers can be enabled or disabled
  • Piano-style damper behavior can be enabled so damping occurs when notes are released
  • Long undamped decay supports sustained pad-like sounds
  • Available for macOS, Windows, and Linux

PartialString is available now as a free download, with an optional pay-what-you-want contribution. The instrument is available in Audio Unit and VST3 formats for macOS, VST3 for Windows, and VST3 for Linux.

Voyage Voyage, Free Shimmer Reverb For Linux, Mac & Windows


Voyage Voyage is a free shimmer reverb, created as part of the KVR Developer Challenge 2026.

Its pitch-shifted tails run through a BBD-style delay emulation with dedicated time control, blending ethereal, rising harmonics with the grain and instability of analog bucket-brigade circuits.

But Voyage Voyage doesn’t stop at reverb, though. Push the decay up and it transforms into a true instrument — a parametric, evolving drone and texture generator.

Two controls take you deeper. The Chaos knob introduces modulation, diffusion and resonators, bending your tails into unpredictable, organic territory. The Exciter knob generates signals that re-trigger the reverb’s delay lines, keeping the sound alive indefinitely — no input required.

Summary:

  • classic decay, tone, mix, input, output, low cut and high cut controls, as expected in a reverb plug-in.
  • Shimmer amount & pitch control, with an additional delay time control featuring the BBD chip emulation.
  • innovative Exciter & Chaos parameters, useful when Voyage Voyage is in self-oscillation / resonator mode.
  • additional features such as resizing capabilities, integrated help, extra accessibility functionalities, mix lock control etc.

Free MPC Sample Project Converter Expands Workflows With MPC One, MPC Live, MPC X/XL


Padbangers has released a free application MPC Sample Project Converter, that’s designed to let you change MPC Sample projects to the bigger MPC Format.

Here’s what they have to say about it:

“For the big standalone MPCs — MPC One, MPC Live and MPC X/XL.

When they import an MPC Sample project, everything ends up crammed into a single track — hard to read and hard to edit. This app splits it into clean tracks and turns your chops and “16 Levels” tuning melodies into real, playable programs: chops become a chop program, tuning melodies become keygroups — plus an in-app preview and an optional template for your own mixer setup. Now also supports converting to MPC 2.”

MPC Sample Project Converter is available now as a free download for Linux, macOS and Windows.
