Back in the “old days”, producers and engineers created delay and echo effects using tape machines. Tap Delay combines the warm sound of vintage tape echo machines with a modern, step sequencer-like tapped delay engine which continues the tradition of the tape echo machines into the 21st century. The Tape simulation includes all relevant aspects for the recreation of a faithful analog tape sound: • Compression and Saturation • Tape hiss • Tape head bias • Wow and Flutter (Tape speed instability) • Smooth speed / delay time changes Three feedback filters with hipass/lowpass and bandpass characteristic simplify the creation of authentic dub echo effects. The built-in Limiter allows for endless feedback sounds. Use live input from any source - Microphone, Guitar, Audiobus and Inter App Audio - or take a song from your iTunes library for processing. Features: • Multi-tap delay machine • 24 taps for rhythmic delay effects • Tape simulation ( Saturation, Noise, Flutter ) • Alias free tape saturation through oversampling. • MIDI controllable including Tempo sync • Delay loop equalizer for dub effect. • Glitch free simulation of variable tape speeds. • Spatial echo rotation effect. • Audiobus 3 compatible with state saving • IAA compatible ( Auria, Cubasis, Garageband ). • AudioUnit AUv3 with parameter automation. • Ableton Link. • Integrated iTunes player.

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.

Verdict
The clearest difference is price: Tap Delay at $1.99 against TB Flowtones's $9.99. Tap Delay also leads on iOS requirement (9.0 vs 13.0). TB Flowtones's advantage is rating (4.7 vs 4.2) and update cadence (every 3 months vs every 29 months). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.
