padthv1 (an old-school polyphonic additive synth)

padthv1 is an an old-school 4-oscillator additive polyphonic synthesizer
with stereo fx. It runs either as a standalone JACK application or an
LV2 instrument plugin. padthv1 is based on the PADsynth algorithm by
Paul Nasca, as a special variant of additive synthesis.

Optional dependencies (autodetected):

lv2 - required to build padthv1's LV2 instrument plugins.
liblo - required for OSC (Open Sound Control) support.

This package uses POSIX filesystem capabilities to execute with
elevated privileges (required for realtime audio processing). This
may be considered a security/stability risk. Please read
http://www.slackbuilds.org/caps/ for more information. To disable
capabilities, pass SETCAP=no to the script.
