38911 Bytes
38911 Bytes is a free software synthesizer developed by Odo Synths. Available format(s): VST for Windows.

2RuleFilter
2RuleFilter is a free filter VST plugin developed by 2Rule. Compatible OS(s): Windows, macOS.
2RuleFilter is a self-resonant moog type filter that allows the filter cut-off frequency to be controlled manually, by LFO, or by an envelope follower. It has a interesting feature called “scrambler” that plays filtered signal randomly depending on the selected beat. The “mix” knob mixes wet and dry signals, The “volume” knob is for setting the output volume level. The”Bit Crusher” produces hard sound. Using its scramble feature you can maintain the rhythmic, choppy, buffered and tempo sync output.
{See video at top of page}
Features:
- High Pass, Low Pass, Band Pass filter.
- Modulation of filter cut-off frequency by LFO (tempo-sync), manually or envelope follower (reversable).
- Bit crusher (16-bit to 1 bit).
- Scrambler that divides one measure to different time interval and plays them randomly.
- Mix balance in between dry (input signal) and wet (filtered and bit crushed).
- Sensitivity that allows the filter cut-off frequency be changed from roughly to smoothly. This effect is the same of parameter smoothing.
