Triple Cheese is a unique freeware synthesizer that employs comb filters for sound generation instead of traditional oscillators or wavetables. It features three comb filter modules arranged in series, each offering eight different modes, allowing for a wide range of sound design possibilities. The synthesizer supports polyphonic (up to 16 voices), duophonic, monophonic, and legato modes, with adjustable portamento time. It includes two ADSR envelopes with customizable sustain stages, two host-sync-able LFOs (one regular and one "vibrator" with delay and amplitude modulation), and a VCA with amplitude modulation and pan controls. Triple Cheese also offers five built-in effects, including chorus, flanger, phaser, delay, and reverb. Modulation sources encompass wheels, velocity, pressure, breath, key follow, and random inputs. The user interface is scalable from 70% to 200% and skinnable, providing flexibility in appearance.

Created in 2005 and still going strong. Podolski is a free, straightforward, CPU-efficient virtual analog synthesizer. One oscillator, one filter, one envelope, and an arpeggiator/sequencer. Simple, but with a few tricks up its sleeve. Create high-quality sounds with ease. Podolski is a simple, CPU-efficient virtual analog synthesizer. Basically a cut-down version of FilterscapeVA with just one oscillator, one filter, one envelope, and two LFOs, it also features a Zebra-style arpeggiator/sequencer plus chorus and delay effects. Podolski's specialties are the click parameter (which emphasizes the filter attack) and its ability to seamlessly morph between three waveforms (WaveWarp). Oscillator with variable symmetry (sawtooth to triangle, PWM) and glide. Combination arpeggiator/16-step sequencer with extra modulation source. ADSR or HDSR, linear or exponential. Sustain has fall/rise control.
