# MonoSlicer

A monophonic sample slicer and sampler instrument built with [JUCE](https://juce.com/) and CMake.

Load an audio file, slice it into regions (automatically via onset detection or manually), and trigger individual slices via MIDI.

## Features

- **Slice & trigger** -- Load WAV, AIFF, FLAC, or OGG files and play slices chromatically via MIDI (starting at C3)
- **Auto-slice** -- Onset-based detection with adjustable sensitivity
- **Manual slice control** -- Click to add, right-click to remove, drag to reposition slice markers
- **Per-voice envelopes** -- Amplitude and filter ADSR envelopes with configurable depth
- **Filter** -- 5-mode biquad filter (LP12, LP24, HP, Bandpass, Notch) with cutoff, resonance, and envelope depth
- **Tone shaping** -- Bass and treble controls
- **Pitch shift** -- Key transpose from -12 to +12 semitones
- **Time stretch** -- Resample to a target beat count at a given BPM
- **Undo/redo** for slice operations
- **Zoomable waveform display** with piano key sidebar and time ruler
- **Full DAW state recall** -- All parameters and slices are saved with your session
- **UI scaling** from 50% to 200%

## Building

Requires CMake 3.22+ and a C++17 compiler.

```sh
make fetch      # Clone JUCE 8.0.9
make configure  # CMake configure
make build      # Build (Release)
```

### Installing

```sh
make install
```

Copies AU and VST3 to the system plugin directories and triggers an Audio Unit rescan.

### Clean

```sh
make clean
```

## Plugin Formats

- Audio Unit (AU)
- VST3
- Standalone

## Usage

1. Load an audio file via the **Load** button, drag-and-drop, or the **<** / **>** buttons to browse the current folder
2. Click **Auto Slice** or manually click on the waveform to place slice markers
3. Play slices via MIDI -- note C3 triggers slice 0, C#3 triggers slice 1, and so on
4. Shape the sound with the amp/filter envelopes, filter, and tone controls
