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.

Gong Amp takes an exciting experimental amplifier from the beginnings of electronic music to the plugin world of today. Available as AUv3 and Standalone. In 1932, Maurice Martenot was looking for a way to make his groundbreaking proto-synthesizer “Ondes” audible beyond what could be archived with the horns and loudspeakers of the time. He developed a set of “diffuseurs”, of which the “Métallique” was one. Instead of a paper cone or horn, Martenot put a gong behind the amplifier circuitry. This seemingly simple idea resulted in resonances and brilliant overtones that excite audiences to this day. Using a complex mixture of convolution processing, physical modeling, and feedback systems, we created an instrument that is true to the responsiveness of the original and even transcends it in terms of sound design possibilities.

Verdict
The clearest difference is price: Gong Amp at $15.99 against Fundamental2's $34.99. Gong Amp also leads on review sentiment (100% vs 57%) and rating (5.0 vs 4.7). Fundamental2's advantage is update cadence (every 4 weeks vs every 27 months). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
