Binary package “terminatorx” in ubuntu bionic
realtime audio synthesizer
terminatorX is a realtime audio synthesizer that allows you to
"scratch" on digitally sampled audio data (*.wav, *.au, *.mp3, etc.)
the way hiphop-DJs scratch on vinyl records. It features multiple
turntables, realtime effects (built-in as well as LADSPA plugin
effects), a sequencer and an easy-to-use GTK+ GUI.
