Kruud

Kruud is a free software synthesizer developed by Xenobioz. Available format(s): VST for Windows.

Kruud is a synthesizer with a drawable low resolution Oscillator. The main Osc has 5 basic waveforms, Pink and white Noise and a drawable user waveform. The waveforms have different modes like Phase Mod, PWM (Square only) and a special morph mode (listed as PWM in the synth) for all but the square wave. The user waveform can mix or morph between two waveforms or do PWM on waveform A.

Features:

1 LFO/SUB OSC.

2 LFOS.

3 ADSRS.

2 Delays of which one can be used to make crude physical modelling.

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.
