UltraTap is a unique multi-tap effect capable of rhythmic delays, glitchy reverbs, huge pad-like volume swells and extraordinary modulation. It’s the perfect tool for creating drum fills, vocal choruses, swelling guitar chords and other evolving effects — everything from reversed reverbs to a massed church choir singing a Gregorian chant in Notre-Dame Cathedral. Features: - Use up to 64 taps to create simple repeats or morph delays into choruses and reverbs. - Speed up or slow down the rhythmic spacing between taps using the Spread knob. - Use the onboard LFOs and envelopes to chop the sound source into stuttered rhythms. - Use the innovative "Slurm" control to smear taps together or modulate them to create truly unique reverbs. - Control the stereo image of taps to alternate between hard-panned and mono. - Over 150 presets designed to inspire; including artist presets by Chris Carter, Colin Newman, Sasha and many more. - Innovative Ribbon and Hotswitch allow for changing any combination of parameters simultaneously. - Use Mix Lock to scroll through presets while keeping the wet-dry mix constant. - Available as an Audio Units AUv3 plug-in and Standalone App.

Fundamental is a sound synthesis software combining the different roots of electronic music history. Its wave engine is a faithful sonic recreation of a vintage Rohde&Schwartz vacuum tube oscillator ( having been widely used at WDR by Stockhausen ) Thanks to sonicLAB audio engine design, Fundamental leaves behind the limitations of the original device by proposing complex modulation possibilities, stochastic distributions addressing the sonic parameters like frequency , gain, stereo panning etc. in continuum, which has not been applicable until now. The Fundamental software presents you 8 instances of this vintage sine wave generator with all the artifacts and richness of a vintage equipment. That combination is we believe something you should experience. Direct Link for manual : https://www.sonic-lab.com/Fundamental/Fundamental2iOS_manual.pdf Fundamental2 brings following new features to the Fundamental1, basically now you can create organic, endless moving textures. (for iOS standalone and AUv3 ) - Ring Modulator, 7 individual modulator oscillators and one carrier oscillator. - A morphing engine which lets you gradually morph between four instances of Fundamental scenes. Also a stochastic manipulation on the 2D morphing panel is possible. - True real time gradual transition between tuning scales. - Rotary Encoder midi controller mapping for high resolution oscillator frequency and gain control with midi hardware. - One can send midi note-on messages to each Fundamental oscillator on discrete midi channels. - A morse code simulator is available on each GEN (sonicLAB LFO design ) which can create custom morse signals to modulate the relevant GEN outputs. - new envelope type "Ernd". Whether you play live electronics, compose for media or just insterested in early electronic music, Fundamental2 is a strong tool. Some of the main features of Fundamental1: ( iOS standalone and AUv3 ) - unique polymorphing wavetable synthesis without any compromise in data content and precision. - 4 dynamic wavetables being rendered for each voice to represent infinitesimal steps of frequency and gain combinations between 1HZ – 3800Hz of the original vacuum tube oscillator. - 8 simultaneous voices each with custom freq, gain, boost, panning and modulation settings. - Custom or harmonic frequency distribution of voices with variable spread ratio and tuning table. - 4 independent stochastic modulations for each voice (32 in total) addressing all parameters with various continuous, discrete distributions and also standard waveforms. - Full MPE support with various configuration possibilites. - Independent Attack / Release envelopes for each voice with various modes, AR times can be set to degrees of randomness. - Vintage oscillator or pure sine wave mode. Recommended iPAD model : A12 processor or higher. Due to screen size challenges, iPAD Mini models are not recommended.

Verdict
The clearest difference is price: UltraTap Delay at $14.99 against Fundamental2's $34.99. UltraTap Delay also leads on review sentiment (88% vs 57%) and device support (3 vs 1). Fundamental2's advantage is update cadence (every 4 weeks vs every 2 months). On rating, ads, in-app purchases and monetization model there is nothing between them.
