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.
