PatternBud is a MIDI CC sequencer for sequencing the patterns of your apps. If you are using a lot of Audio/MIDI apps with multiple patterns, then you can use PatternBud and sequence the patterns quickly. You can add multiple tracks to PatternBud. Each track has its own MIDI CC number and MIDI Channel. You can add unlimited steps to your tracks. Each step has a MIDI CC or MIDI Program Change value which you can set by tapping the step. The steps can also have multiple actions as well. You can assign actions to your steps for jumping a random/specific step or jumping a random/specific pattern. You can control all the Bud apps as well as the other apps that support changing their patterns with MIDI CC or AU parameters. PatternBud is a MIDI app and it does not produce any audio. For the AUv3 plugin, you need an AUv3 host app such as AUM, Cubase, apeMatrix, BeatMaker etc.
