TB Flowtones Virtual Analog Synthesizer app and AUv3 plug-in Thanks to it's true VA synthesis engine, the use of analog-modelled non-linear filters and extensive modulation options, Flowtones sounds warmer and more analog than digital romplers and wavetable-based synths. TB Flowtones comes as stand-alone app as well as AUv3 plugin. True virtual analog synthesis features: - 4 VCO architecture (two voice layers with two VCOs each) - 4 synthesis engine types, in part modelled after famous analog synthesisers - 36 analog VCO waveforms featuring all classic waveforms and more - All VCO waveforms support pulse width modulation - Full stereo and mono unison modes for each VCO independently - Noise and subharmonic oscillators for each VCO - Unique ring and self-modulation matrix - High-quality, warm, non-linear filters (VCF) with over 30 filter types, including unique multi-resonance filters Modulation features: - Four LFOs with 30 waveforms each - LFOs can modulate other LFOs, including themselves! - Three additional envelope generators, with key velocity modulation - Quick access to modulation strengths through context menus - Hundreds of modulation signal paths available - LFOs can produce noise as waveform to randomly modulate other parameters; for example to simulate slight variations in analog filter parameters as they happen in analog circuits. Pro-grade effects - Studio-quality reverb, delay, and chorus effects - Unique formant filter to add vocal character - Analog and digital distortion / bit crushing effects - Master equaliser and peak limiter for final touch - Non-linear power supply simulation for authentic interaction between notes Step sequencer - Fully integrated, intuitive step sequencer - Can trigger chords and note series / phrases - Can run asynchronously or synchronously to the host - Smart copy/paste of note series to improve workflow - Smart zoom: edit fine details while keeping an overview over the full sequence Presets and intelligent randomizer - Flowtones comes with hundreds of presets to spark your creativity - Intelligent randomizer to explore endless sound synthesis possibilities What you should know: - Licenses acquired for this platform are not compatible with other platforms. - Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4 or later models.

Oscidia is an AUv3 plugin for iOS which can be loaded into your favorite DAW allowing you to use it as a sound source for any MIDI source. Its wide range of features and oscillator types allow it to produce a vast variety of sounds. In particular, the inclusion of WaveTable greatly expands the traditional wave types and brings a wealth of modulation options. Oscidia has 3 oscillators per voice, and each oscillator can be a different wavetable – all working and morphing together to create some incredibly amazing sounds. Oscidia includes SINE, SAW, SQUARE, TRIANGLE, SUPERSAW, SUPERSQUARE, WAVETABLE and ADDITIVE wave types. You can import and export compatible wavetables using drag and drop directly to the WaveTable manager. Wavetables support morphing and warping (phase distortion), all controlled by the Mod Matrix routing. The SINE and TRIANGLE wave types both support several wave folding modes which allow dramatic real-time morphing too. Oscidia also supports 5 filter types which support 12/24dB modes and morphable LP/BP/HP filter modes which can be automated from the Mod Matrix or via the Sequencer. The sequencer itself is very unique and allows up to 3 simultaneous ARPs to play at the same time. Each ARP can directly control the 3 oscillator levels independently per step, as well as the pitch, filter morph, cutoff frequency, probability, gate, note repeat and ties. This allows for some really complex rhythms to be created that are not tied to pitch. Oscidia Features: • 3 Oscillators Per Voice. • Support for Wavetable and Additive synthesis. • WaveTable supports Morph and Warp (Phase Distortion) features. • 4 LFOs Per Voice. • 5 Filter types with 12/24-bit slopes and morphable LP/BP/HP. • 4 ADSR (Attack, Decay, Sustain, Release ) or FEG (Fluid Envelope Generators). • Wave Folding is available for basic waveforms such as SINE and TRIANGLE. • OSC Sync. • XMod & Ring Mod (on osc1 & osc2). • Additive Synthesis for glass, metallic and bell like tones. • Build in Sequencer (with 3 independent ARPs). • Mod Matrix. • MPE Mode. • Internal Effects - reverb, delay, chorus, Haas, and Phaser effects. • Drag and Drop for import and export presets and wavetables. • Build in Help Manual.
