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.

K7D is a powerful and affordable, vintage tape delay effect plugin for iOS. K7D recreates the hardware echo machines of the past using Imaginando’s signature style of obsessive analog emulation, but with an enhanced level of control from a sleek, modern interface. Using this approach allows a whole new world of creative possibilities, while still retaining a warm, full-bodied analog sound, bursting with character and personality. To give K7D it’s distinctive analog flavour, we studied and analysed the tiny details of what makes classic hardware delays great, and painstakingly recreated every subtle nuance for a fantastically authentic sound. Available as a standalone app and audio unit plugin, you can use it digital audio stations for iOS such as Garage Band, AUM, Cubasis, Auria, Audiobus, etc. Features - 1ms to 1 sec. dual playhead analog modeled delay with noise, tape distortion and mechanical vibration models - Modeled microphone input with pre-amp saturation - Normal and Ping Pong modes - Optimized gain staging and saturation algorithms for very musical results - Delay time spread between heads and stereo width control - High pass and Low pass filter on feedback path - Powerful LFO bipolar time modulation with multiple waveforms (sine, triangular, saw, square, sample and hold and filtered sample and hold) and possibility of inverted LFO phase on second play head (for added stereo imaging) - Delay time syncable with BPM - Possibility of delay time modulation via incoming midi notes - Oscilloscope visualisation of audio waveform and LFO waveform - Built-in patch manager - Audiounit compatible

Verdict

The call

The clearest difference is update cadence: K7D at every 3 months against Tap Delay's every 29 months. K7D also leads on rating (4.6 vs 4.2) and ratings volume (79 vs 13). Tap Delay's advantage is price ($1.99 vs $3.99) and iOS requirement (9.0 vs 17.0). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.
