Flucoma x Bela

---

Warning: built and tested with experimental Bela image v0.5.0alpha2, unlikely to work on older builds.

Bela setup for building

This method assumes building on Bela and cross-compiling via distcc (locally via arm-linux-gnueabihf apparently also works, but I couldn't get it to yet).

• Bela hardware: https://bela.io
• Flucoma requires CMake >3.11 which (as of writing) is available on Bela via this image: https://github.com/BelaPlatform/bela-image-builder/releases/tag/v0.5.0alpha2
• Bela will need Internet access: https://learn.bela.io/using-bela/bela-techniques/connecting-to-wifi/
• distcc setup on Bela: https://gist.github.com/jarmitage/2a5dffbcfdd5532371f097e9bb80e4b0
  • Make sure to see comment thread for how to use distcc at the same time as sharing network over USB
• When doing cmake you may observe the process getting stuck in a loop at the -- Getting container node sizes step. This should end if you wait long enough. Not sure what the problem is.

SuperCollider

---

Install

• Download from Releases page
• Copy to Bela:

scp -r /path/to/FluidCorpusManipulation root@bela.local:/usr/share/SuperCollider/Extensions/FluidCorpusManipulation

Usage

• Bela SuperCollider reference: https://learn.bela.io/using-bela/languages/supercollider/
• See examples in /scd

Build

ssh root@bela.local
git clone https://github.com/supercollider/supercollider
git clone https://github.com/flucoma/flucoma-sc
cd flucoma-sc && mkdir -p build && cd build
cmake -DSC_PATH=../../supercollider-src -DCMAKE_CXX_COMPILER=distcc-clang++ -DCMAKE_C_COMPILER=distcc-clang -DCMAKE_CXX_FLAGS='-mfpu=neon -mfloat-abi=hard' -DCMAKE_C_FLAGS='-mfpu=neon -mfloat-abi=hard' -DDOCS=OFF ..
make install
cp -r ../install/FluidCorpusManipulation /usr/share/SuperCollider/Extensions/FluidCorpusManipulation

Pure Data

---

Install

• Download from Releases page
• Unzip to find the externals
• Create a pd-externals folder if you haven't already, see https://learn.bela.io/using-bela/languages/pure-data/#abstractions
• Copy the Flucoma externals to Bela (not the entire outer folder itself):
  • Via the Bela IDE: open the pd-externals "project" and drag-and-drop the contents of the folder onto the browser window.
  • Via scp: scp -r /path/to/FluidCorpusManipulation/* root@bela.local:Bela/projects/pd-externals/.

Usage

• Every patch must include [declare -lib fluid_libmanipulation]
• Bela Pure Data reference: https://learn.bela.io/using-bela/languages/pure-data/
• See examples in /pd (TBC)

Build

git clone https://github.com/pure-data/pure-data
git clone https://github.com/flucoma/flucoma-pd
cd flucoma-pd && mkdir -p build && cd build
cmake -DPD_PATH=../../pure-data -DCMAKE_CXX_COMPILER=distcc-clang++ -DCMAKE_C_COMPILER=distcc-clang -DCMAKE_CXX_FLAGS='-mfpu=neon -mfloat-abi=hard' -DCMAKE_C_FLAGS='-mfpu=neon -mfloat-abi=hard' -DDOCS=OFF ..
make install
cp -r ../install/FluidCorpusManipulation/* /Bela/projects/pd-externals/

C++

---

Install

• Download from Releases page
• Copy to Bela:

scp -r /FluidCorpusManipulation root@bela.local:/usr/share/

Usage

• Bela C++ reference: https://learn.bela.io/using-bela/languages/c-plus-plus/
• See examples in /cpp (TBC)

Build

If you need to save space on Bela, download eigen and HISSTools_Library dependencies as zip instead of git cloning, and copy these to Bela (scp -r eigen root@bela.local:eigen etc) and add to the cmake command below -DEIGEN_PATH=../../eigen -DHISS_PATH=../../HISSTools_library.

git clone https://github.com/flucoma/flucoma-core
cd flucoma-core && mkdir -p build && cd build
cmake -DCMAKE_CXX_COMPILER=distcc-clang++ -DCMAKE_C_COMPILER=distcc-clang -DCMAKE_CXX_FLAGS='-mfpu=neon -mfloat-abi=hard' -DCMAKE_C_FLAGS='-mfpu=neon -mfloat-abi=hard' -DDOCS=OFF ..
make install
# add to path within Bela project?
