Cube Synth is a groundbreaking new software instrument giving you the power and flexibility of additive synthesis together with easy editing and morphing capabilities. Macro parameters allow you to control this beast with unequalled ease. Intelligent sound morphing capabilities enables you to easily create complex evolving sound scapes, vocal phrases or stunning rhythms simply by choosing up to four sound sources from a predefined set. Then add one of the predefined envelopes and a unique, complex sound preset containing thousands of parameters is created! If you want to dive deeper into the inner secrets of this synthesis monster you can manipulate each parameter individually to get precise control over the sound. A number of high level parameters such as Brightness and Harmonic spread control hundreds of synthesis parameters in a way modeled after the inner workings of natural instruments. Cube Synth gives you also a new method of getting randomly generated sound patches in a way you never experienced before: roll the dice! Every single try gives you a new unique sound patch, really every try, promised… Synthesis • over 400 sound presets • four morphable sound sources • up to 512 partials per voice • harmonic/inharmonic spectra • arbitrary noise spectra • morphable filter banks • 3 Envelopes with tempo sync • 64 time/level segments per envelope Arpeggiator • Uses programmable sequences with up to 32 steps. • Can trigger single notes and chords. • Unique randomizer generates Arpeggios with 100% usability. • 32 Arpeggios included, unlimited useer arpeggios possible. • For each step you can program tie, accent, transposition and note order Effects • Chorus • Phaser • Overdrive • Ensemble • Echo/Delay • Reverb Global • Audiobus 2 compatible (Input slot) with state saving • Support for Ableton Link. • Inter-app audio compatible (Instrument/Generator) • CoreMIDI / Virtual MIDI • Audio recorder with Metronome. • Upload to SoundCloud and File Export. • Audio pasteboard.

VAPolyMk3 is a multi synthesis polyphonic synthesizer for iPhone, iPad and Mac. Inspired by the last generation of classic analog synthesizers in the late 1980’s such as Oberheim Matrix series synthesizers, It offers Subtractive Synthesis and modular FM Synthesis. It operates as a stand alone or as an AudioUnit Extension (AUv3). Stand Alone supports Ableton Link, MIDI and audio file export. Oscillator Section features 3 Oscillators and 3 Modulation Oscillators. Each Oscillator has envelope and amplifier. Oscillators can be routed for Subtractive Synthesis and FM Synthesis. Signal from Oscillators are routed to mixer, resonant low pass filter, resonant hight pass filter and amplifier. The synthesizer also features two ADSR envelopes per voice, two LFO and analog style sequencer. Built-in Effects include delay, chorus, flanger, reverb, eq and compressor. VAPolyMk3 also includes sequencer which features piano roll editor and parameter automation. Project files can be saved in iCloud Drive, so that the project can be accessed from iPhone, iPad or Mac. Main Features 3 oscillators and 3 modulation oscillators can be routed for Subtractive Synthesis and FM Synthesis. Analog Style CV Sequencer. Maximum 8 voice polyphony. it depends on performance of the device it is running. Built-in effects and sequencer. Support MIDI 2.0. Support Foot Pedal (CC#11, CC#64) and Per Note Control. Support Audio Unit Extension (AUv3) Works on iPhone, iPad and Mac. Support iCloud Drive to share project files between the platforms. Audio Export. Linear PCM format (AIFF, WAV and CAF) and compressed format (AAC) Support Ableton Link, Bluetooth MIDI, MIDI In / Out. Option to turn off anti-aliasing for devices with less CPU power. Include 271 Factory Presets. System Requirements iOS 17.0 or later This app requires a lot of CPU power. Devices with Apple Silicon or equivalent A series chip are recommended. A13 Fusion or above is highly recommended. If sound is distorted when using a device with less CPU power, turn Anti-Aliasing-Option off or reduce number of voices. AudioUnit Extension (AUv3) requires host application which support AudioUnit Extension. AudioUnit Extension is supported by Apple Logic and Apple Garage Band on iOS and macOS. For any other DAW, it depends on the application and some of them don’t support AudioUnit Extension.
