Read full description

MelodyBud is an AUv3 MIDI sequencer with great generative sequencing capabilities. Instead of a traditional sequencer, you can randomise your notes, velocity, octave, and gate length of your steps, add ratchets and glide to make it more interesting! One of the most powerful feature of MelodyBud is "parameter-locking". With parameter-locks, you can set a step's randomisation values individually. That lets you create richer melodies. For entering the parameter-locking mode, you can simply tap a step's number on the top of the sequencer. The step and the control knobs turn orange when you enter the parameter-locking mode. If you edit a control when you are in the parameter-lock mode, the sequencer will execute that configuration for that step instead of the global configuration. You can tap the step's number again for exiting the parameter-lock mode. You can work in more than 40 scales, you can even change them while the sequencer is running. With the AUv3 plugin, you can change them with the AU parameters and even modulate/automate them along with other parameters. The standalone version supports Ableton Link which lets you in-sync with other Ableton Link enabled apps. Please note that MelodyBud is a MIDI app. The standalone version has an optional internal synth where you can enable or disable on the settings menu. The AUv3 plugin requires an audio app for output. For the AUv3 functionality, it needs to be hosted within an app such as AUM, Loopy Pro, Cubasis, Logic Pro, Nanostudio, Drambo, or apeMatrix etc.
