Audio production requires deep integration with your operating system’s audio architecture (like ASIO drivers). Portable software is forced to run in an isolated environment or "sandbox."

The primary sources for cracked portable software are unmoderated torrent sites and file hosting services. Security firms routinely scan these files. Results? Keyloggers, remote access trojans (RATs), and hidden cryptominers. That "Cubase 5 Portable.exe" file might be using your GPU to mine Monero while you try to lay down a drum track.
