SAR VSTs has announced the release of Logana, a free VST instrument and effect plug-in that uses physical modeling to emulate analog hardware. This creates warm non-aliasing waveforms with little CPU use.

Features:

• Three analog style oscillators with four waveforms (Sine, Saw, Pulse, and Triangle).
• Noise generator with variable level and color (tone).
• Modulation matrix and modulation envelope.
• LFO with Sine and triangle waveforms able to modulate pitch or pulse-width on oscillator 1, 2, 3, or all of them.
• Lowpass filter with adjustable slope (12db, 24db, or 36db), cut-off, resonance, and a separate cut-off envelope.
• Amplitude envelope and overdrive distortion.
