The Moog Model 15 App is the first Moog modular synthesizer and synthesis educational tool created exclusively for iPad, iPhone and iPod touch. Each facet of the Moog Model 15 modular synthesizer has been meticulously recreated in this application to ensure the power and transcendent sound quality of each module remains intact. The character, harmonic complexity and mystique of the Moog Model 15’s modules, from the legendary Moog 921–series oscillators and 904A Low Pass Filter, to the coveted 907 Fixed Filter Bank have been painstakingly preserved. In order to develop the most immersive and expressive modular interface possible, the Model 15 App has been designed utilizing Apple’s new Metal advanced graphics engine. This ensures that all zooming, panning and modular patching throughout the application feels completely natural, something that would have been impossible otherwise. The Model 15 App features both monophonic and 4-voice polyphonic operation is easily commanded via 4 seamlessly integrated controllers. Simple swipes and taps provide instant access to a traditional Moog keyboard, 1150 ribbon controller, 8-step sequencing arpeggiator and the award-winning Animoog keyboard with 22 built-in scales and polyphonic modulation capabilities. Also included are extended features which expand the capabilities of the app beyond the traditional offerings of the hardware Moog Model 15. These include total MIDI integration, assignment for external control, use as a MIDI controller, dedicated Audio Bridge and MIDI Bridge modules, looping recorder module with overdubbing, a master ping-pong delay module and a new extension cabinet that includes additional amplifiers and voltage-controlled reversible attenuators that can be used for effects like ring-modulation. Because the Model 15 App utilizes Apple’s Metal technology, only 64-bit devices are supported. Compatible devices include iPhone 5s or newer, iPod touch 6 or newer, iPad Air or newer, and the iPad Pro. The Model 15 App requires iOS version 12.4 or later to work. Additional Features • Ships with over 160 unique presets • Recreates the sound of a hardware Moog Model 15 modular synthesizer • Easily share presets and recordings with anyone • Tutorial patches to assist all experience levels • Intuitive patching and cable coloring • Support for landscape and portrait modes • Voltage-controlled stereo ping-pong delay • Expressive sequencing arpeggiator • Moog 1150 Ribbon controller • Real-time looping recorder with overdub and immediate sharing • Up to two controllers on-screen (iPad only) • Optional left-handed UI operation Supports • AUv3 Audio Unit Extensions • 3D Touch and Apple Pencil integration for after pressure • Note-per-channel MIDI controllers • Ableton Link • Inter-App Audio and Audiobus • MIDI Bridge and Audio Bridge • 7 and 14-Bit MIDI • MIDI Program Change • Bluetooth LE MIDI controllers • Typing keyboards for shortcuts and musical typing • AudioCopy, AudioPaste and AudioShare

The Guitar Analyzer app is a tool for analyzing and fine-tuning your acoustic or electric guitar: - A highly accurate guitar tuner with a cent scale indicator - An automatic scale tuner for all strings - A sound analyzer with multiple types of visual graphs for both the entire fretboard and individual strings - A sustain meter with sustain measurement by duration and factor - A dual custom sound oscillator for certain tasks where you need to hear the resonant frequency of an object or the beats between two specified frequencies - Conveniently select from over 50 well-known guitar brands to create your own list of guitars to explore and quickly switch between them - Choose from three string tunings (standard 6-string guitar, standard 4-string bass, and custom tuning for up to 12 strings in any key from 127 MIDI keys across the entire octave range) - Adjustable microphone sensitivity, noise threshold, and a choice between 2 types of amplitude analysis (peak and RMS) With this app, you can accurately tune your guitar, adjust the scale, and even choose the best guitar from several. By recording the sound across all frets for each string, you can use the displayed graphs to identify fret defects or nut placement, see unevenness in the sound in different places, see where the problem might be by changing the pitch shift of the frets, find the "dead note" and its position on the fretboard, as well as the resonant frequency of the instrument
