TXV
TXV is part of the TX Modular System - open source audio-visual software for modular synthesis and video generation.
TX Modular comes is 2 parts: the main TX Modular system and audio engine are built with SuperCollider.
TXV, the visual engine, is a separate app built with openFrameworks that connects to the TX Modular System.
There are TXV builds for MacOS and Windows. The TXV build for MacOS will only work with Mojave (10.14) or earlier (10.11, 10.12 & 10.13) - but NOT Catalina (10.15) or later.
Building TXV with openFrameworks on Linux or MacOS Catalina (10.15) is currently untested.
