FM Filter 2 allows you to apply Yutani's non-linear filters to external audio sources.

Key Features:

• Filters: 26 multi-mode filters (well-behaved to gnarly analog modelled).
• Control: Filters and gates can be controlled via Audio (peak or RMS) or MIDI.
• Modulation: Three LFOs, modwheel, and MIDI velocity support.
• Effects: Stereo widening and a distortion module.

A small synthesis-based drum machine featuring 12 drum sounds with variants.

Key features include:

• Remappable MIDI notes.
• Ability to link note velocity to drum kit parameters.
• Retro pixel aesthetic.

A utility for arpeggiating incoming MIDI data. It allows users to play chords and have them arpeggiated out.

Key features include:

• Velocity, Modwheel, and Control Change (CC) automation.
• Note probabilities and automatic randomization.
• Support for playing over multiple octaves and swing settings.
• Ability to set speed dynamically and synchronize patterns to the host (free or MIDI).
• Pattern/block copy-pasting.
• Supports docking into TCP/MCP.

A tool for building complex chains of delays and reverbs using a node-based system. Each node represents a delay where:

• X axis: Controls delay time.
• Y axis: Controls volume.
• Radius: Controls feedback amount.
• Arc: Indicates the frequency range allowed to pass each feedback round.
• Knob: Controls node panning.

Nodes can be routed to each other to create complex feedback loops. Routing sends are applied after filters but before feedback gain. The arc on a routing arrow indicates the volume of the send.

Key features include:

• Tempo synchronization (3/4, 4/4, or 5/4 rhythm).
• Filters, distortion, saturation, modulation, and more on every tap.
• Granular resynthesis and pitch shifting.
• FFT Reverb node (indicated in red) for lush sounds.
• Tuned mode for Karplus-style string synthesis.

Note: Mute all unused nodes to significantly lower CPU usage.

Bric-a-brac adds textures to existing sounds (e.g., adding noise to beats or organic creaks to synths).

Key Features:

• 4 Sample Slots: Can be triggered or looped.
• Envelope Control: Per sample, choose between envelope follower, thresholded, or triggered envelopes.
• Modulation: One LFO modulator and a lowpass/highpass filter per sample (modulated by envelope and/or LFO).
• Timing: Variable pre-delay per sample.

An FM modulated filter useful for making monophonic bass sounds thicker. It operates in two main modes:

1. MIDI Mode: Designed to be placed behind a bass synth. It follows MIDI notes (adjusting cutoff per note) and performs FM modulation based on the incoming MIDI pitch. The envelope is triggered by MIDI.
2. Audio Mode: Used for more destructive processing. It can modulate the cutoff frequency using its own signal (self-modulation) or take a modulation signal from inputs 3/4 (stereo 3/4 or mono 3+4).

Key features include:

• 2 linear and 4 non-linear filter types.
• Mode morphing between LP, BP, HP, and BR.
• Basic decay envelope and LFO modulation.
• Audio rate cutoff modulation.

A shimmer reverb plugin featuring 5 different algorithms for large reverb spaces.

Key features include:

• 4 time-domain algorithms and 1 STFT-based algorithm.
• Shimmer (via pitch shifting), saturation, and ice effects.
• Preset EQ curves.
• UI featuring fluid dynamics.

Partials is a modal resonator effect with 5-note polyphony, suitable for string-like or marimba-like sounds.

Control Modes:

• Non-MIDI Mode: Uses internal resonators to transform audio input. Use the UI keyboard to set up to 5 fundamental pitches.
• MIDI Mode: (Toggle in bottom right) Sets fundamental resonator frequencies to played MIDI notes. Max polyphony is 5.

Key Features:

• Models: 10 physical models plus custom partial models (drawn by user).
• Processing: Choice between Frequency domain mode (efficient) and Time domain mode (allows feedback but may be unstable).
• Sampling: Drag impulse samples onto the four pads in 'sampling mode' (set play-mode knob to the right).
• Other: Stereo spinning/vibrato, filter envelopes, and presets.

A machine for combining two sounds into ambient soundscapes using STFT (Short-Time Fourier Transform). It emphasizes frequencies common to both signals while attenuating differences, behaving similarly to a harmonic reverb.

Key features include:

• Shimmer: Copies energy to twice the frequency (iterative octave doubling).
• Aether: Similar to shimmer but for fifths.
• Scorch: Input saturation.
• Ruin: Output saturation.
• Diffusion: Spectral blur.
• Ice: Chops small bandwidth bits from energy at random and copies them to higher frequencies for a 'cold' sound.

Dusk Verb is a multi-effect plugin designed to enhance atmospheric arpeggios.

Key Features:

• 3 Reverberation algorithms.
• 6 Granular resampler modes.
• 4 Frequency shifter / pitch shifter modes.
• 3 Audio shimmer modes.
• X/Y controls for automation.

A lo-fi effect combining a lowpass-gate (modelled after a famous unit) and a random detuning module.

Key features include:

• Pitch instability.
• Adaptive saturation.
• Modelled noise processed through a compander.
