Here comes the the crazy twin-sister of Ruismaker, designed for people who want to design their own percussion sounds from scratch. Ruismaker FM's simple, yet flexible synthesis engine lets you create anything from snaredrums, kickdrums and spacy toms to weird and unconventional percussive sounds and effects. Ruismaker FM is a unique drumsynth plugin (i.e. it does not use samples), which is coupled with a creative Euclidean sequencer when run in standalone mode. The plugin is fully AUv3 (Audio Unit) compatible: - Seamless integration with Garageband and other AU hosts - Audio Unit Instrument: making music on iOS doesn't get more convenient - Supports AUv3 Multi-Out in AUM and ApeMatrix - Each sound is modeled using authentic analog and FM algorithms; - Comes with dozens of unique customizable models - Does not use any samples; all sounds are synthesized in realtime, on the fly - Light on the CPU, so you can run lots of Ruismaker FMs simultaneously - Fully automatable parameters (requires host support) and MIDI CC controllable - Has its own preset manager The standalone sequencer is refreshingly different: - Program patterns using Euclidean algorithms - Powerful random feature and mutation probability settings per channel - Syncs with Ableton Link or MIDI Clock - Exports WAV and MIDI - Compatible with Audiobus 3 (including MIDI IN/OUT mode) - CoreMIDI In and Out - AU MIDI output for on-screen pads User manual available on Ruismaker.com

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.
