To compile SpectMorph, use the usual

./configure
make
make install

Configure should automatically determine via pkg-config whether the lv2 development headers are available. When the LV2 plugin doesn't get built, install them.

The VST Plugin is available for Linux, macOS and 64-bit Windows, and should work in many different hosts, such as Bitwig, Renoise, Cubase and others. For Linux hosts that support LV2, using the SpectMorph LV2 plugin is the preferred way of integration.

The VST Plugin has four properties that can be automated by the host, called Control #1 ... Control #4. To use these, for instance for linear morphing, the Control Input can be set to "Control Signal #1" (or #2) in the UI. After that the host can change the morphing from left source to right source and back.

SpectMorph provides a LV2 Plugin, which can be used together with Linux DAWs that support LV2, such as Ardour, Qtractor and others.

The smjack program is a fully functional JACK Client using SpectMorph. You need to connect midi input and audio output (for instance with using QJackCtl).

The control inputs (Control Signal #1 ... Control Signal #4) are mapped to the midi CC controls (General Purpose Controller 1..4).

If you are a packager, packages should install the standard instrument set to a system-wide location. The instrument location is prefix dependant. If SpectMorph is installed in

/usr

then the instruments should go to

/usr/share/spectmorph/instruments

If you are building from the original source tarball, this should work automatically, the instruments are bundled and will be installed during

$ make install

If you're building from git, you are responsible for obtaining a copy of the standard instrument tarball. Extract the SpectMorph release source tarball. The location will be something like

spectmorph-0.4.1/data/spectmorph-instruments-0.4.1.tar.xz

You can either ensure that these instruments live in ($XDG_DATA_HOME/spectmorph):

~/.local/share/spectmorph/instruments/standard

or copy the instrment tarball to the data directory of your git checkout. In this case SpectMorph will automatically install the instruments to the system-wide location (like the original release tarball does).

Note that if incompatible changes happen to the file format, the git version will no longer work with the released instruments set. In that case, feel free to ask for a tarball for your git version.
