Free Audio Plugins & Softwares for Windows

Krolar SX-2

Krolar SX-2 is a free software synthesizer developed by Kriminal. Available format(s): VST for Windows.

The Krolar SX-2 was inspired by the 1978/9 hardware Roland synth, the SH-2.

Features:

OSC1: sine/saw/pulse.

OSC2: saw/pulse/noise.

SubOsc: square (-1 oct below the settings of OSC1).

Modulator (LFO): sine/square/S&H with rate and delay.

AutoBend: begins below/above (-2/+2 octaves) key pressed and slides to that pitch.

PWM: LFO/MAn/Env – the slider adjusts the pulse width or the amount of LFO/Env modulation (the LFO for PWM is a smooth sine with no delay).

Pitch Mod: controls amount of pitch modulation by the LFO.

Tuning: OSC2 has its own tuning section, Wide and Narrow (+/-1750 cents or +/-200 cents).

The SH-2 was monophonic, Krolar SX-2 has a small red button (top right) that allows you to switch from monophonic (low note priority) to polyphonic (6 voices).

The other features are self explanatory.
