Foundation 2 is a compact two-voice modular synthesizer. It is assembled comprising twelve modules, but any of them can easily be replaced with any other module in the Eurorack format.

The synthesizer includes:

• MIDI2 - a duo interface for converting MIDI commands to control voltages (CV).
• Two modules "Oscillator" – allow you to receive a saw, a sine, a triangle and a meander with PWM (pulse width modulation).
• LFO2 - two low frequency generators. Each has individual outputs for the sawtooth and square signal. Pulse width modulation is available for the upper LFO.
• MOD - ring modulation with three modes of operation and separate level control for each input.
• M3 is a passive splitter and two 2-channel unregulated mixers.
• Mixer is a four-channel mixer (3 channels can be used as independent attenuators).
• Filter - multimode voltage controlled filter. It has individual outputs for low (LP), high (HP), band (BP) and notch filters.
• Two modules "ADSR" - envelope generators with the adjustment of attack, decay, sustain and release.
• Dual VCA - two classic voltage-controlled amplifiers. Each has an independent CV input with an attenuator.
• Outs - provides audio output from the modular system. It has two independent channels, which allows it to be used in both stereo and dual mono mode. A preamp for headphones with an independent level control is also provided.

It’s the predecessor of Foundation 3.1.
