Nettle – Free experimental synthesizer by Fellusive

Nettle is a software instrument that explores the unique and relatively under-explored world of scanned synthesis. The timbre of the sounds you create constantly evolve, as the waveform produced is made by tracing (scanning!) the positions of masses that are always in motion. These masses are excited by you pressing a key on your MIDI controller – this simulates the action of a hammer striking the connection of masses. Through the user’s manipulation of the masses, the springs that connect them, and the hammer that excites them, a wide range of dynamic, and almost sentient, sounds are possible.

Features include:
* 32-voice polyphony.
* Fully automatable knobs.
* Filter (low-pass, high-pass) and reverb available for signal processing.
* Four LFOs and ADSRs available for modulation, along with two sources for modulation via your MIDI controller.
* Built-in presets, along with the ability for users to save and modify their own presets.
* A randomize button.
