v4.0.0•Updated Jan 3, 2026

A 6-operator FM Synthesizer with effect chain. Fully DX-7 compatible, so you can load any DX-7 sysex files in as sound banks. Full edit controls over all 6 operators, and a serial effects chain of stereo chorus, a light compressor, tape delay, and simple reverb all add up to warm up the chilly FM timbres.

v4.0.1•Updated Jan 3, 2026

An eight source 8-bit retro percussion machine based on DrPetter's sfxr sound generator. C-3 through C-4 trigger the sounds and each can be set with a generated patch of a specific type "coin" or "laser" etc. Or click the ? type to fully randomize that sound unit. Play with repeats, duty cycles, and a phaser to really make some wild sounds.

v4.0.0•Updated Jan 3, 2026

A warm tape saturator with one-knob operation. It uses 4x oversampling for clarity, soft saturation, low frequency resonance at around 80Hz, high frequency loss with saturation, hysteresis simulation and output gain compensation.

v4.0.0•Updated Jan 3, 2026

A vintage effect that adds various types of noise, wobble, saturation, a bit of reverb and tape degradation to your signal chain. Toggle off any specific effect to remove it from the stack.

v4.0.0•Updated Jan 3, 2026

A tempo synchronized gate effect. Choose a gate speed, and modify the envelope to cut up your audio into different sized slices, with soft or smooth edges.

v4.0.0•Updated Jan 3, 2026

Waveform based bell and chime synthesizer. The extreme far ends of the octaves detune similar to Pippo. It also features the chorus and reverb modules from Padawan.

v4.0.0•Updated Jan 3, 2026

A monophonic synth designed to create retro sounding bass lines and shrill leads. Phase adjustable wave mix, the ever popular randomizer, and a nice knob for octave selection.

v4.0.0•Updated Jan 3, 2026

An analog style bass synthesizer that uses several unique techniques to create a thick & rich sound. Oscillator 1 is a blend of a pulse & crushed triangle, while Oscillator 2 uses a custom designed super-saw blended with a crushed sine. The synthesizer also uses a custom designed cascade filter system with a feedback chain for adding analog warmth to the sound. LFO and envelope modulators can target 8 different parameters in both positives and negatives using the modulation matrix.

v4.0.0•Updated Jan 3, 2026

An instrument that closely emulates the sounds of a classic Nintendo Entertainment System. There are only three wave types: square, triangle, and noise. There is also a simple arpeggiator for making classic 8-bit sounding tunes. Entirely DSP, no samples.

v4.0.0•Updated Jan 3, 2026

A tape-like delay module. Designed specifically to emulate the classic tape delays, Maelcum has internal tape noise generation, with variable mix, and either tempo based or manually entered delay time. Rub a dub dub.

v4.0.0•Updated Jan 3, 2026

A unique synth based on an array of self-oscillating delay units controlled via a very simple interface. The resulting sounds vary from toy piano to plucked strings, and even some bell-like tones. It will detune a bit a the high & low ends of the scales due to Karplus-Strong algorithm used.

v4.0.0•Updated Jan 3, 2026

A drawn waveform monosynth conceptually based on mark andrews' step oscillator. Simply draw your waveform using the sliders, create your envelope, and adjust the effects. Both warp and delay effects have handy XY based panels for live tweaking and automation.

v4.0.0•Updated Jan 3, 2026

A filter effect with an internal variable length step sequencer. It allows you to select the type of filter, cutoff and resonance for each step, as well as start, end, and sequencer modes for a wide variety of effects. Breakdown can be hand set to create wah wah, gate, and wobble effects, or use the patch randomizer for some intense audio mangling.

v4.0.0•Updated Jan 3, 2026

A stereo effect that uses the incoming audio to drive its internal synth. The results range from a subtle analog accompaniment, to wet analog sounds, to screeching distortion.Try it on drums, vocals, leads, whatever.

v4.0.00•Updated Jan 3, 2026

A mellotron-like synthesizer based on remastered versions of J.P. Hovercraft's original Mellotron multisamples. Tapeworm includes five voice types, tuning, attack, release, and midi automation.

v4.0.0•Updated Jan 3, 2026

A sample player that utilizes granular pitch shifting and sample slicing to play back a sample in new and unusual ways. The first row of sliders controls the actual playhead position in the sample at that step. The second row controls the coarse pitch, which is multiplied by the pitch variance setting at the top. The bottom row of toggles allows each individual slice to be reversed.

v4.0.0•Updated Jan 3, 2026

A delay effect with an internal variable length step sequencer. It allows you to select from six delay types: 0.1, 1, or 10 second delays with or without interpolation. Each step allows for specific time and feedback adjustments. You can also adjust the start, end, and sequencer modes. Mashup can be hand set to create convoluted delay effects, or used to create very tight decimations.

v4.0.0•Updated Jan 3, 2026

A waveform based mallet synthesizer. It features a nice chorus module, and does a very good job of simulating steel drums, and other Caribbean type percussion.

v4.0.0•Updated Jan 3, 2026

A synthesizer based on the classic Nintendo Entertainment System's PSG audio system. More than 30 waveforms from many memorable sounds and tones have been meticulously deconstructed and tamed. Chiptune made simple.

v4.0.0•Updated Jan 3, 2026

A granular generator for creating percussive sounds. There are 80 source wavelets for each channel. All sources are pitch shiftable. Each channel has a separate granular processor with pitch, size and rate parameters as well as random adjustors. A bitcrush rounds each channel off.

v4.0.0•Updated Jan 3, 2026

A multisample based ambience generator. Using original field recordings by Shawn Hatfield, Field allows you to generate suitable backing ambience for any track.

v4.0.0•Updated Jan 3, 2026

A vst effect best used for live performance. It has an inline sampler that you can grab samples from the current live effect channel. You can then trim the loop, reverse, and process with effects in realtime. The left joystick controls bitrate and pitch, while the right joystick controls delay time and delay feedback.

v4.0.0•Updated Jan 3, 2026

A granular delay effect with detailed synchronization features and lots of randomization thrown in the mix. This can produce anything from a simple digital delay sound, to full on new synthesis from extremely small grains and sync rates.

v4.0.0•Updated Jan 3, 2026

A granular pitch shifter effect with an internal variable length step sequencer. It allows you to modify pitch and grain size for each step, as well as edit start, end, and sequencer modes, and granular envelope type for a wide variety of effects. Sideslip can be hand set to create gentle rythimc pitch corrections, or completely destroy a loop or sample by granular deconstruction.

v4.0.0•Updated Jan 3, 2026

Toad is a drum kit based on the classic Nintendo Entertainment System. Excellent quality percussive bits are here in abundance. ROMPler fun for everyone.
