Full Bucket Music WhispAir

Full Bucket Music WhispAirOne of Full Bucket Music’s entries in this year’s KVR Developer Challenge is WhispAir, a fantastic wavetable synthesizer. Its three oscillators offer many ways to get creative, including sync, FM and AM. WhispAir also features a multi-mode stereo filter and no less than four envelopes and three LFOs for modulation. For extra lush, wide sounds, there’s a chorus effect and a unison mode. While you’re downloading WhispAir, be sure to check out Grain Strain, Full Bucket Music’s other entry.

In addition to two envelopes and an LFO, GR-8 offers an integrated effect section with EQ, distortion, phaser, chorus/flanger, delay and reverb.

Fellusive Nettle

Fellusive NettleThis one’s a personal favorite of mine. Nettle by Fellusive is an innovative software instrument that uses scanned synthesis. It generates sounds by scanning the positions of moving masses, which you can control using your MIDI controller. Imagine a bunch of objects connected by springs, and using a hammer to set them in motion. Nettle lets you adjust various parameters of the model, which are all connected. It rewards the experimentally minded with a wide variety of unique sounds.

Nettle is a VST and AU plug-in for macOS.
