padthv1-universal - cross-platform port of padthv1

padthv1 is an old-school 4-oscillator subtractive polyphonic synthesizer with stereo fx, based on the PADsynth algorithm by Paul Nasca, as a special variant of additive synthesis. Written by rncbc (a.k.a. Rui Nuno Capela).

Originally, padthv1 is for Linux only, providing a standalone JACK application, and a LV2 plugin. The latter is also available on Windows, but few DAWs support LV2 there (currently only REAPER, Ardour and MixBus).

This project aims at porting padthv1 to more common platforms and plugin formats, with the great power of DISTRHO Plugin Framework (DPF). I believe more musicians will enjoy this amazing synthesizer.

NOTE: This project superceded my fork of padthv1 with DPF implementation. Any newer features and bugfixes will only be applied here.

Features

• Cross-platform support
  • Windows
  • Linux
  • macOS (to be tested)
• Multi plugin formats
  • VST 2.4
  • VST3
  • LV2
  • CLAP

Requirements

• Qt framework, C++ class library and tools for cross-platform application and UI development, https://qt.io/
• FFTW3, a C library for computing the discrete Fourier transform (DFT) in one or more dimensions, http://www.fftw.org
• DISTRHO Plugin Framework, cross-platform unified audio plugin framework, https://github.com/distrho/dpf

Source code structure

• plugin/: The main implementation. This is the core of the project.
• src/: Official padthv1 repository. Serves as a Git submodule.
• dpf/: DISTRHO Plugin Framework repository. Serves as a Git submodule.

Principle

This project is based on DPF, for its multi-platform support. DPF provides a full solution for audio plugins, from base structures to final plugin binaries. You can build plugins for multi platforms and formats from just one source tree.

This project separates DPF port codes from official padthv1 repository, and uses its own CMake build rules. As padthv1 is in active development, this design helps keeping pace to rncbc's updates easily (by simply a git pull in src/ directory).

How to build

On Linux

0. Install dependencies

Make sure you have the latest Qt 6.x and FFTW3 installed. If not, install it. Refer to the document of your distribution.

# Ubuntu
sudo apt install qt6-base-dev libfftw3 libfftw3-dev

# Arch Linux
sudo pacman -S qt6-base fftw

1. Clone source code

This project has submodules, so make sure you don't omit --recursive:

git clone https://github.com/<to_be_named> padthv1 --recursive

If you forget, run the following command:

git submodule update --init --recursive

2. Configure and build

cd padthv1
cmake -S . -B build
cmake --build build

3. Run plugin

Built plugin resides in padthv1/build/bin. Copy them to you DAW's plugin scan paths.

Notice

• This project does not provide Standalone JACK support. Go to official repo if you need it.
• padthv1 macOS build should supported both Intel and Apple Silicon platform, as long as you have the right Qt 6.x development package installed (e.g. by MacPorts). But I don't own a MacBook. Please help me test the plugin and give me a report.
