LFOH! vs Hilda Synthesizer
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
LFOH!
This app is an advanced LFO tool that enhances classic cycling envelopes with unique shaping and morphing features. It functions as both an audio processor and a MIDI modulator, offering extensive control over modulation signals.
- Morphable and selectable waveforms
- Advanced waveform shaping
- Sample and Hold circuit
- Audio amplitude modulation
- MIDI CC output
- AUv3 extension

LFOH! is an augmented, stunning (as the name suggests!), LFO which enhances the possibilities of the classic cycling envelope by adding control over a set of advanced and unique features. LFOH! is a single oscillator LFO and has a set of continuously morphable and selectable waveforms that represents the core of its modulation signal. Apart from the classic frequency and phase parameters (which make it capable of all of the classic modulation stuff), the waveform can also be shaped by swinging its cycles, bending its curve, squeezing portions of oscillation in the same period of time, scaled and transformed while exceeding its boundaries. An additional Sample and Hold circuit provides quantization for the resulting signal. A tool you already know, with the most advanced features: simple and powerful. LFOH! is both an audio processor and a MIDI modulator: while is capable to send its modulation signal out as MIDI CC (according to the MIDI routing flexibility of the app that hosts it), it can also modulate the amplitude of incoming audio. *** Please note: LFOH! is an Audio Unit extension (AUv3) – it only works in an AUv3 host app like AUM, Drambo, Cubasis, etc... ***
Hilda Synthesizer
This app offers a complex oscillator monosynth with a blend of west-coast and east-coast synthesis techniques. It features a wave folder, lowpass gate, 12-mode filter, and VCA circuit, all meticulously circuit-modelled for authentic analog or digital sound. It functions as a playable synth, MIDI sequencer, and audio effect.
- Complex Oscillator Monosynth
- Wave folder and lowpass gate
- 12-mode filter
- Circuit-modelled analog sound
- Built-in 16-step MIDI Sequencer
- Audio effect for external audio
- AUv3 compatibility

Hilda is a Complex Oscillator Monosynth, inspired by the most interesting aspects of both west-coast and east-coast synthesis techniques. You'll find a wave folder, lowpass gate, and audio-rate modulations, but also a 12-mode filter and traditional VCA circuit. All parts of the instrument are carefully circuit-modelled to sound as analog (or digital, where applicable) as possible. It's like a best-of-all-worlds semi modular synth, but without the patch cables. The unique mix of different synthesis components adds up to a unique sounding electronic instrument, which can be used as a playable synthesizer, a MIDI sequencer and an audio effect for external audio - or any combination of those three. - Full Audio Unit compatibility (AUv3 instrument, audio effect and MIDI processor modes supported) - Universal design (iPhone and iPad; iPad Air 2 or higher recommended) - Built-in analog style 16 Step MIDI Sequencer with custom scales - 12 mode filter, based on the Oberheim Xpander design - Drone mode lets you [partially] bypass the VCA/LPG and just go with the flow - DIY Lo-Fi digital delay circuit emulation - Live pads with effects that can be triggered via the UI (or via exposed AU Parameters) - All synth settings exposed a AU Parameters (for automation and MIDI learning in your host of choice) - MIDI Processor plugin mode disables synth to save CPU - Carefully handcrafted by yours truly, to capture the essence of my love for tinkering and experimenting with sound :-) Find the user manual on ruismaker.com
