Ripplemaker: a West Coast Flavored (Semi-)Modular Synth The freedom and versatility of a modular synth in a stylish mobile package. In typical West Coast fashion the available modules, such as complex oscillator, lowpass gate, FM, mathematical utilities and slope generator, are designed for exploration and experimentation. The virtual patch cables will let you take your sound wherever you want to take it, from morphing basslines to evolving generative drones. A modular playground Even if you’re not familiar with modulars, wavefolders or control voltage you can dive right in, because all modules are prewired; offering a powerful monosynth without using a single cable. Then whip out the virtual cables and start patching. Ripplemaker is designed for fun - big enough to lose yourself into, yet intuitive enough to not get lost. Standalone sequencer goodness Sometimes you want to get away from your DAW and just play. That’s why Ripplemaker, beside being an AU plugin, also comes with a standalone sequencer app that helps you get creative. It has a random pattern generator with scale locks, a realtime probability-based mutation engine and it syncs with your other apps and hardware via Ableton Link or MIDI Clock. Download the user manual on www.ruismaker.com Connectivity beyond cables: obviously in a modular synth it’s all about cables. But Ripplemaker takes connectivity to the another level: - AUv3 (Audio Unit Plugin) Extension for use in iOS DAWs - Universal design (works on iPad 4+, iPhone 5S+, iPod Touch 6G+) - CoreMIDI, Virtual MIDI, Bluetooth MIDI, - Audiobus 3, including AB3 MIDI IN+OUT and State Saving - Ableton Link - MIDI Clock Sync - WAV export, MIDI file export, AU preset export

auGEN X bridges the creative musical world of artists with the exacting scientific world of audio engineers. What started as a precision audio test utility has grown into a fun experimental sound design instrument. On one end use auGEN X to help set up, test, calibrate, and optimize your audio system. On the other use it to create a wide variety of interesting sounds. auGEN X has a full-featured audio oscillator, a high quality noise generator, and an impulse generator. The simple yet powerful user interface is designed for fast, precise, intuitive control over your signals. auGEN X works both as a Stand-Alone App and as an AUv3 Audio Unit Extension responding to MIDI In and BPM Sync from Hosts. I started making this app because as an audio electronics engineer I could not find a single audio generator that does everything that I require AND is an AUv3 Audio Unit. auGEN X has expanded into a musical tool for exploring and learning sound design. Our goal is for auGEN X to be an Essential in your audio toolbox. We hope you enjoy it and we’re excited to hear the cool things that you do with auGEN X!
