IterativeSinCluster is an additive synthesizer. This synth computes 512 sine waves for each note to make tone cluster. I somehow thought "iterative sin" is a valid term. Correct term is "recursive sine".

CubicPadSynth is a wavetable synthesizer which uses PADsynth algorithm to generate oscillator tables. Cubic interpolation is used to get smooth sound even at inaudible low frequency range. LFO waveform can be directly drawn.

LightPadSynth is a lightweight version of CubicPadSynth. For efficiency, interpolation is changed to linear. Also pitch modulation is omitted. Instead, a delay is added for each voice.

WaveCymbal is an attempt to make a cymbal synthesizer with banded wave-guide model. The result is more like dragging bunch of empty cans or thin metal plate on asphalt rather than cymbal.

CollidingCombSynth is an experimental synthesizer which sounds like bowed string. Equipped with 24 Karplus-Strong string models which collide to each other. Tuning of pitch is possible, but difficult. So mostly suitable for sound effects.

TrapezoidSynth is a monophonic synthesizer equipped with 2 trapezoid oscillator. Trapezoid oscillator is based on PTR (Polynomial Transition Regions) and it has a drawback that increasing noise at high frequency. Therefore 8 times oversampled. 2 pitch shifters are added to make some chord.

FDNCymbal is a cymbal sound synthesizer. It can also be used as an effect. Unlike the name, most of metallic texture comes from Schroeder allpass section rather than FDN (feedback delay network). FDN section makes nice impact sound when `FDN.Time` is short. Tremolo is added to simulate wobbling of cymbal.

SyncSawSynth is a 32 voice polyphonic synthesizer using up to 10th order PTR sawtooth oscillator. Just a basic synthesizer but very easy to make a noise similar to low battery sound of some toys.

EnvelopedSine is an additive synthesizer that computes 64 sine waves for each note. Difference to IterativeSinCluster is that this synth has AD envelope and saturator for each oscillator. EnvelopedSine is better suited for percussive sounds.

Based on the Oberheim OB-X. It attempts to recreate its sound and behaviours, but as the original was very limited in some important ways a number of things were added or altered to the original design. The OB-Xd was designed to sound as good and as rich as the original. It implements micro random detuning which is a big part of that sound.

Digits is a phase distortion synthesizer inspired by Casio's CZ series but takes that form of synthesis to the limit. Create warm pads, glitchy sounds, dirty basses, filthy sweeps, screaming leads, and anything in-between.
