Soup Machine is a work-in-progress project to create a hardware Digital Audio Workstation, similar to the Teenage Engineering OP-1.

As the hardware used, a Maschine (the first version a.k.a. MK1), is hooked into a Raspberry Pi v3, which acts as the computer for the software DAW.

As you can see, its in very early state 😅

Development Setup

1. Install Raspbian Lite on the Raspberry Pi

2. Install the required libraries and software

   sudo apt-get install libusb-1.0-0-dev libhidapi-dev librtmidi-dev
   sudo apt -y install build-essential openssl curl

3. Install the Cabl library from source

   # Get source
   git clone https://github.com/shaduzlabs/cabl.git
   cd cabl
   git checkout -b develop && git pull origin develop
   git submodule update --init --recursive
   mkdir build && cd build
   # Build and install
   cmake ..
   make
   sudo make install

4. Install Nim (make sure you download the latest version)

   # Get Nim sources
   cd ~
   mkdir tmp
   cd tmp
   curl https://nim-lang.org/download/nim-VERSION.tar.xz -O
   tar -xJvf nim-VERSION.tar.xz
   cd nim-VERSION
   
   # Build Nim
   ./build.sh
   
   # Build Nim tooling
   ./bin/nim c koch
   ./koch tools
   ./kock nimble
   
   # Install Nim
   sh ./install.sh $HOME/.nimble
   cp ./bin/* $HOME/.nimble/nim/bin/
   
   # Add to path
   export PATH="${PATH}":$HOME/.nimble/nim/bin:$HOME/.nimble/bin
   
   # Upgrade nimble
   nimble refresh -y
   nimble install -y nimble
   mv $HOME/.nimble/nim/bin/nimble $HOME/.nimble/nim/bin/nimble-orig

5. If you want to do memory checks with Valgrind, make sure you install it from sources, as Raspbian comes with a buggy one:

   sudo apt install autotools-dev automake
   git clone git://sourceware.org/git/valgrind.git
   cd valgrind
   ./autogen.sh
   ./configure
   make
   sudo make install

Common Tasks

• To compile and build, run nimble start
• To perform a memory check, run nimble memcheck
  • Logs will be saved to ./valgrind/log.txt

Road map

• Use Cabl from Nim
• Elm-ish API
  • Controls create events
  • Declarative view
  • Cmd-style actions like sound and lights
• Musical keyboard with pads
• Drum sampler

As an inspiration, use the OP-1 user manual and the OP-1 explainer playlist on YouTube
