Settings.

You can create a settings file at "~/.config/sfzq/settings" (or "$XDG_CONFIG_HOME/sfzq/settings" if that's your jam), which can include these settings:

samples-directory = "path"

Sets a default path where you keep your samples. When the file chooser comes up, it will start in this directory.

num-voices = number

Sets the maximum number of voices that can be sounded at once.

show-voices-used = boolean

Controls whether current number of voices used is displayed in the UI. Set to true or false.

tunings-directory = "path"

Sets a default path where you keep your tunings. When the file chooser comes up to choose a tuning, it will start in this directory.

keyboard-mappings-directory = "path"

Sets a default path where you keep your keyboard mappings. When the file chooser comes up to choose a keyboard mapping, it will start in this directory.

Tunings

Alternate ("microtonal") tunings are supported in the Scala (".scl") file format (thanks to the Surge Tuning Library).

Building

At build time, you will need the headers for CLAP, Cairo, and X11. If your distro's package manager doesn't have a package for the CLAP headers (and you're not using Nix), you can get the headers, and tell the Makefile where to find them by creating a "Makefile.local" file with a line like CFLAGS += -I/path/to/clap/include. Other than that, you should be able to build it just by typing make.

For Programmers

SFZQ is built on three independent components, each of which could be extracted and used in other projects:

SFZPlayer: reads and plays SFZ and SF2 files
CLAPFramework: a simple framework for CLAP plugins
CairoWidgets: a widget library using Cairo to draw
