Free Virtual Instruments

sg-modutron mini

sg-modutron mini is a free software synthesizer developed by Synthgeek. Available format(s): VST for Windows.

This is a simple 1-oscillator synth based on “virtual circuit-bending”. The initial idea started out as an attempt at making a bass synth version of the APC synth. It turned out to be impossible to get it to track pitch at all, so more experimentation ensued, and this is the result. It does track pitch, but often sounds will change across the keyboard or possibly even stop making sound at a certain key.

Some of the ideas used here will doubtless be put to use in a larger multi-osc synth, though whether an expanded version of this exact synth will be developed remains to be seen.

sg-lunettik pack 1

sg-lunettik pack 1 is a free software synthesizer developed by Synthgeek. Available format(s): VST for Windows.

This is a series of small noisemaking devices inspired by Lunettas- in a nutshell, Lunettas are simple circuits, often based on CMOS logic chips. To quote mosc from the electro-music forums, “These machines are named after Stanley Lunetta of Sacramento, California… Lunettas are very simple, digital, noisy, quirky, and lots of fun.”

Note that these are not meant as emulations of any specific circuit, they are just inspired by the concept. Like the circuits which inspired them, they don’t necessarily do things “right”, but they generate interesting sounds. If you like noisy, droney, and/or buzzy stuff based on square waves, check ’em out. The first pack includes three simple generators: SR1, OR1, and BC1, which are named after the logic functions used in their design (Shift Register, OR gate, and Binary Counter).

sg-grainbot

sg-grainbot is a free software synthesizer developed by Synthgeek. Available format(s): VST for Windows 64b.

Grainbot is an experimental synth based on granular synthesis and mathematically generated noise. It’s not made for traditional bass/lead/pad type stuff (though it can do that if pressed), but it is capable of a wide range of other sounds: mechanical and engine-type sounds, rhythmic percussion sequences, random bleepery, drones, ambiences, and more. It can also process external audio.

There are two sound sources: the grain generator (which can granulate internal sound sources or an audio input), and “gen 1”, a chaotic math-based sound generator. There is also a ring modulator which uses these two generators as its inputs. You can choose between 5 different input sources for the grain generator: live audio input, a built-in analog-style oscillator, the input amplitude modulated by the oscillator, gen 1, or audio input from a file. The sound generators are processed through a filter with 5 types (lo pass, hi pass, notch, and 2 flavors of band pass) and a selectable number of stages. There is also a stereo delay effect which can sync to host tempo (or not). Various parameters (including the delay effect) can be modulated with 2 step sequencers, 3 LFOs, and a 6-stage envelope. The modulation routing is provided via matrix. Besides the modulators mentioned above, there are also matrix inputs for key tracking and velocity, and a “combiner” which uses various math formulas to combine any two mod sources in various ways.

Originally released for the 2009 KVR Developer Challenge, since updated.

sg-apcx2

sg-apcx2 is a free software synthesizer developed by Synthgeek. Available format(s): VST for Windows.

This is an expanded version of the original APC1 synth from synthgeek, including more filter options, distortion, and modulation via 3 LFOs, 4 step sequencers, and the combiner module from the noisebot synths. Think of it as a groovebox for crazy synth fx. It can also be coerced into lo-fi squelchy bassline territory, though due to it’s nature, tuning can be tricky.

This has been rebuilt to include features developed for the noisebot synths. The sound sources here are two Atari Punk Console-style oscillators.
