Caustic Song file (optional):
This tutorial looks at how you can use Patterns in Caustic as a way to create variations of a default preset within a single machine. It shows how you can create "Preset Patterns" and work with them independently of "Note Patterns".
It might not seem intuitive at first, but keeping "Preset Patterns" and "Note Patterns" separate can be pretty useful. For example, you could create a melody or a recurring motif with a ModSynth pattern, and set it up to send notes to a SubSynth that has multiple "Preset Patterns" and switch among them during your song. As you insert patterns in SONG MODE, you could have the same ModSynth pattern playing throughout, but pair it with different SubSynth "Preset Patterns" to change the sound that the notes are triggering.
