LFOH! vs OODA
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... ***
OODA
This music creation tool offers a unique approach to MIDI sequencing with interactive and semi-generative features. Create complex melodies and rhythms by connecting steps with conditional "wormholes" and manipulate sequences in real-time without losing your groove.
- Interactive step sequencing with conditional wormholes
- Real-time sequence manipulation
- Four independent voices for complex patterns
- Configurable grid size (4x4 or 8x8)
- External MIDI device and in-app keyboard recording
- Flexible MIDI connectivity and output options
- Standalone and AUv3 host compatibility

OODA is a fresh take on the classic MIDI step sequencer with interactive and semi-generative enhancements. What makes OODA unique is that you can connect arbitrary steps together using conditional “wormholes” to add structured (or random) variation to your sequences. Another unique feature is that OODA’s underlying model is decoupled from its voices. This allows you to interact with your sequences and create melodic variations in real time without affecting your groove. OODA’s open-ended sequence grid can be easily configured for almost any use case. Anything from simple melodies and bass parts to semi-generative chords and arpeggios, OODA can do it all with a little creativity! Features: - Record sequences up to 64 steps with the in-app keyboard or an external MIDI device - Interact with your sequence on the fly using four “action” buttons - Link together steps using conditional wormholes to create structure and variation - Create complex patterns of melody and rhythm using four independent voices - Change voice speed independent of sequencer speed - Comes with ten factory presets to give you an idea of what OODA is capable of - Explore a deep, yet focused set of parameters - Sequencer Settings - Grid size (4x4 or 8x8) - Sync voices to sequencer rate - Sequencer rate - Sequencer direction - Shift amount (semitones) - Live toggle rests and skips - Wormhole Patcher - Conditionally “reroute” your sequence by connecting arbitrary steps - Per-step wormholes - Destination and normal steps per wormhole - Trig conditions and probability for moving through each wormhole (see below for list) - Voice Settings - Four voices with independent settings - Enable/disable - Rate of play (in beat time from 16 bars to 32nd T) - Includes unique note values based on the Golden Ratio for maximum generative fun! - Length of note (10% to 100%) - Variety of rules for selecting notes from active step (see below for list) - Pitch offset - Unique pattern control for creating rhythms and polymeters, now with step options - Easily add holds, ties, accents (positive and negative), ratchets, and trig conditions - MIDI velocity and channel - Flexible Connectivity - Use in a compatible audio unit host like AUM, or in standalone mode - Control multiple instruments at once with five MIDI outputs - One for all voices together, and one for each voice by itself - Sync to the tempo of other devices using Ableton Link or MIDI clock (standalone) - Send MIDI clock to external synths (standalone, experimental feature) - Connect to Bluetooth MIDI devices - Modulate OODA’s parameters in a compatible AUv3 host (audio unit) - Eight unique MIDI CC outputs derived from OODA’s sequencer model - Sequencer X, Sequencer Y, Sequence Phase, Action OR, and per-voice random - Includes macOS app! IMPORTANT: OODA can be used as a standalone app or as an AUv3 plugin. There are some important differences between the two. The standalone app features a simple, toggleable "Sidekick Synth" so you can quickly experiment with OODA. Of course, you can also send MIDI from the standalone app. Meanwhile, the OODA AUv3 plugin does NOT generate sound. Instead, you use it to send MIDI (note messages) to other apps, plugins, or hardware instruments that do the actual sound generation. AUv3 plugins must be used inside a compatible host.

Verdict
LFOH! and OODA both sit at 4.7 stars, but that hides the real split: 91% of OODA's written reviews are positive against 56% of LFOH!'s. LFOH!'s advantage is price ($1.99 vs $8.99) and iOS requirement (9.3 vs 13.0). On rating, ratings volume, ads and in-app purchases there is nothing between them.
