LMMS-zyn-fusion test

See the CHANGELOG for current changes

What's this?

This is a test repository for testing LMMS together with the new zyn-fusion, using a new plugin technique. It's not official.

What does work, what doesn't?

What should work:

  • load and save files
  • preview XMZ files from 'My Presets' (left sidebar in LMMS)
  • drag-drop XMZ files from 'My Presets' over songs
  • drag-drop the zyn instrument on tracks from old zyn to convert them
  • drag-drop zyn widgets on automation patterns (you must keep the F1 key pressed, in contrast to LMMS, where it's the control key)
  • exporting songs, e.g. to WAV

What still needs to be done:

  • LMMS can crash if project loading time takes more than 10 seconds
  • make removing connections more easy
  • connect zyn widgets to LMMS controllers (not only automation patterns)
  • reviews for
    • the spa concept in general
    • the LMMS implementation
    • the zyn implementation

Requirements

  • Linux or similar (installer only)
  • C++11 compiler
  • usual zyn-fusion/lmms requirements
    • especially perl's "List::MoreUtils" (On Arch Linux: "perl-list-moreutils")
  • a stable internet connection
  • at least 1.5 GB of disk space

Precautions

  • As with every experimental audio projects, start with low volume to avoid damaging your ears/speakers
  • The saved files can currently not be loaded with LMMS' master and maybe they never will

How to get it running?

There are two ways. In both cases, you should not need any admin privileges. Your system root and your LMMS config will not be touched.

Automized install by making fresh clones

This is suited if you have enough bandwidth and disk space and don't plan to work on the sources.

Starting in this (the README's) directory, do

./build.sh
./lmms

Note: During the download, there is usually no progress displayed. Submodules like LMMS or CALF can take 10 minutes even with a good connection. Please be patient.

If build.sh fails, you can fix it in the script and usually re-run the script. Please make a PR if you have fixed something.

Install by re-using your current git-worktrees

If you have worktrees of e.g. LMMS or zyn and want to re-use them, this repo is purely informative. Don't use the submodules here. Instead, you should check out the following (use git clone -b <branchname>):

Make sure to run git submodule update --init --recursive in all four repos (not in this repo). The --depth option can speed things up if you don't need the submodule histories, but it may fail.

Then, go into this repo (the main repo) and type git submodule status. Go to each of the four repos and check out the corresponding commits.

Compile + Install

Please keep the order as below

  • spa
    • Follow README instructions for a normal install
    • Write down the PKG config file's directory for later. It's found in your install folder, subdirectories lib64/pkgconfig or lib/pkgconfig. The file contains a spa.c file. Example: ~/cprogs/spa/install/lib64/pkgconfig
  • mruby-zest-build
    • Compile like in the README
    • Run make pack
  • zynaddsubfx
    • Do a build like in the README, but prepend PKG_CONFIG_PATH=$PKG_CONFIG_PATH:<spa pkg config directory, see above> to the cmake command and add the following CMake variables:
      • -DZynFusionDir=<path to where fusion is>/package
      • -DGuiModule=zest
    • At that stage, starting zyn (./src/zynaddsfubx from the build dir) should already work and start up zyn-fusion.
    • Write down the path of the newly built spa plugin, which is usually ending on src/Output/libzynaddsubfx_spa.so
  • LMMS
    • Do a build like in the README, but prepend PKG_CONFIG_PATH=$PKG_CONFIG_PATH:<spa pkg config directory, see above> to the cmake command. An install should not be required.
    • To start LMMS, prepend SPA_PATH=<path to where zyn's spa lib is> before the lmms binary.
    • At that stage, LMMS should be startable, and on the plugins menu you should see a zyn plugin with the new zest logo

Reporting issues

  • Issues from LMMS, zyn and fusion can go to the issue tracker of this project, if they are plugin related.
  • Issues considering the spa library itself (e.g. design issues) should go preferably to the spa issue tracker or to the spa mirror's issue tracker.
