*** Note *** Although mLFO can run as a stand-alone app, the recommended way to use it is as an AUv3 plugin from inside a suitable AU Host app, such as AUM, AudioBus, Cubasis etc. mLFO AUv3 is a set of 16 programmable MIDI LFOs with a extensive set of features: - Multiple parameters per LFO, including variability. - Independent output and MIDI channel per LFO. - Wide rate range, from 1/128 to 130442 beats. - 9 factory and 16 user shapes. - Custom shapes: free and ADSR. - 4 trigger modes, including random retrigger (every incoming note triggers a random LFO). - MIDI Thru. mLFO uses parts of the following copyrighted material, the use of which is hereby acknowledged.

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: mLFO at $5.99 against Fundamental2's $34.99. mLFO also leads on review sentiment (80% vs 57%) and device support (3 vs 1). Fundamental2's advantage is update cadence (every 4 weeks vs every 2 months) and iOS requirement (12 vs 15.6). On rating, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
mLFO costs $5.99 and Fundamental2 $34.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Fundamental2 holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 19 and 6 respectively. Written reviews complicate that: 80% of mLFO's written reviews are positive against 57% of Fundamental2's, so the app with the better star average is not the one people write more warmly about.
mLFO ships an update every 2 months, Fundamental2 every 4 weeks. The most recent releases landed on September 24, 2026 and June 28, 2026 respectively.
