The Minimoog Model D App is a software transmutation of the world’s first portable synthesizer, the Minimoog Model D®. Anyone can jump in and play with over 160 included presets or lay fingers to the controls and begin exploring vast magical realms of creative potential for iPad, iPhone, iPod Touch and Mac. The Minimoog Model D App incorporates a number of inspiring sound creation tools and capabilities not present on its analog antecedent. New functions include the ability to play chords with up to four-note polyphony, an easy-to-use arpeggiator for rhythmic pattern creation, a real time looping recorder with unlimited overdubbing capacity, a tempo-synchronizable stereo ping pong delay module, and the Bender -- a wide-range stereo time modulation effect module. The Minimoog Model D App also supports AUv3 Audio Unit extensions, which allows multiple instances of this powerful instrument to be used simultaneously within compatible iOS apps supporting AUv3. A BRIEF HISTORY Introduced by Moog in 1970, the Minimoog Model D served as the archetype for all electronic keyboards that followed. It gave users the ability to design their own sounds, translating imagination into reality. The Minimoog’s portability, affordability and accessibility made it the go-to instrument for musicians looking to expand beyond the traditional sounds of the time. Bernie Worrell used the Minimoog Model D to establish Parliament Funkadelic’s futuristic funk sound. Kraftwerk employed the Minimoog Model D on the successful concept album Autobahn, sparking an entirely new genre. Gary Numan replaced his live band’s guitars with Minimoog Model Ds, creating the prototype for industrial music. The classic sound of the Minimoog Model D can be heard on Bob Marley’s Catch A Fire, Michael Jackson’s Thriller and Dr. Dre’s The Chronic; Detailed in the mini-doc series “A Brief History Of The Minimoog”.

KV331 Audio is proud to announce the availability of their award winning software synthesizer SynthMaster 2.9 on iOS platform. As being the first app developed using KV331 Audio’s new cross-platform UI framework, SynthMaster 2 runs as a standalone app or AUv3 plugin on iPads with iOS 11 and above. SynthMaster 2 supports native resolutions of various iPad devices. User interfaces are provided for 9.7, 11 and 12.9 inch iPads in 4 different skins (Blue, White, Dark, Proto). Separate interfaces are provided for the AudioUnit plugin as well. SynthMaster 2 comes with 1000 factory presets designed by world class sound designers such as BigTone, Nori Ubukata, NatLife and Yuli Yolo. Thanks to the comprehensive preset browsing features, users can easily filter presets by author name, bank name, instrument type or preset name and find the sounds that they are looking for. There’s also an IAP Shop, which lets users purchase additional sounds: 1. "Desktop Presets Upgrade": This IAP adds all factory presets in SynthMaster 2.9, increasing the total preset count to 2000. 2. "All Expansions Bundle": This IAP adds all current 38 SynthMaster preset expansion banks. Sound Engine: At the heart of SynthMaster 2’s powerful sound engine lies its oscillators, modulators, and filters. Oscillators: The oscillators can operate in 4 different modes to generate sound: 1. In Basic mode, the oscillator plays single cycle waveforms or samples. With the Oscillator Unison turned on, up to 8 voices per oscillator can be played. 2. In Additive mode, 8 Basic oscillators can be stacked up to create richer tones. 3. In Wavetable mode, the oscillator can play wavetables with up to 256 frames. 4. In Vector mode, 4 Basic oscillators are mixed in 2 dimensions. Modulators: Modulators are simply basic oscillators that can be added to other oscillators or modulate other oscillators’ or modulators’ phases. By connecting modulators to other oscillators or modulators, complex FM tones can be synthesized. Importing Wave Files into SynthMaster: While designing sounds, users can easily import wave files into SynthMaster 2. SynthMaster 2 can categorize those files into waveforms, wavetables or multi samples and import them accordingly. Filters: Once the sound is generated by the oscillators it goes through SynthMaster’s filters, which can operate in 6 different categories: Digital, VAnalog, Ladder, Diode Ladder, State Variable and Bite. Custom distortion can be applied before or after the filters as well. Modulation Architecture: SynthMaster 2 features a comprehensive modulation architecture with a wide range of modulation sources: 1. MIDI controls 2. Macros controls 3. 4 ADSR envelopes per layer 4. 4 Multisegmented envelopes per payer 5. 4 LFOs per layer 6. 4 Sequencers per layer 7. 4 Keyscalers per layer There’s real-time visual feedback that lets users see how modulation sources and targets are changing when a note is being played. This is extremely helpful when designing sounds with SynthMaster 2. New modulations can be created easily by dragging and dropping a modulation source onto a knob or slider control. Users can easily see which controls are modulated by a modulation source by clicking on that source. Controls that are being modulated by that source will display modulation amounts. By long pressing a control, the modulation amount can be edited without the need to go through the mod matrix. Arp/Sequencer: SynthMaster features a comprehensive arpeggiator / sequencer with 32 steps. Users can easily create sequences by recording steps one by one. Effects: Each of the 2 layers in SynthMaster has 5 insert effect slots. 13 different types of effects can be instantiated in any of those slots. There are also 2 global effect send busses which can be used to create more complex effect routings.
