For those in the modular synth world, the extensive CV/Gate outputs provide an enticing bridge between the digital and analog realms. Real-time sequence adjustments, pattern chaining, and innovative features like the “Randomness” parameter make it a dynamic tool in both studio and live performanc...
--sub-langs "en.*,ja" (where "en.*" is a regex pattern that matches "en" followed by 0 or more of any character). You can prefix the language code with a "-" to exclude it from the requested languages, e.g. --sub- langs all,-live_chat. Use --list-subs for a list of ...
