Ruismaker vs Lagrange
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Ruismaker
This app is an analog drumsynth that creates sounds using authentic synthesis algorithms, not samples. It features a creative Euclidean sequencer for pattern programming and integrates seamlessly with AUv3 hosts like Garageband. It offers customizable sound models and MIDI control for flexible music production.
- Analog and FM synthesis sound modeling
- Sample-free sound generation
- Euclidean sequencer
- AUv3 compatibility
- MIDI CC control
- WAV and MIDI export
- Ableton Link sync

What the reviews say: "A must-have drum synth for electronic music lovers on iOS" - Keyboard Mag "All of this comes together in a vision that’s really playable [...] this is another excellent choice for the iPad." - CreateDigitalMusic "Small, compact and easy to use, Ruismaker is both inexpensive and a perfectly credible choice if you are after solid drum synth sounds." - MusicAppBlog -- Ruismaker is a unique drumsynth plugin (i.e. it does not use samples), which is coupled with a creative Euclidean sequencer when run in standalone mode. The plugin is fully AUv3 (Audio Unit) compatible: - Seamless integration with Garageband and other AU hosts - Audio Unit Instrument: making music on iOS doesn't get more convenient - Supports Multi-Output AUv3 in AUM and ApeMatrix! - Each sound is modeled using authentic analog and FM algorithms; - Comes with dozens of unique customizable models - Does not use any samples; all sounds are synthesized in realtime, on the fly - Emulates analog components, introducing subtle, natural fluctuations in the sound - Light on the CPU, so you can run lots of Ruismakers simultaneously - Fully automatable parameters (requires host support) and MIDI CC controllable - Has its own preset manager The standalone sequencer is refreshingly different: - Program patterns using Euclidean algorithms - Powerful random feature and mutation probability settings per channel - Syncs with Ableton Link or MIDI Clock - Exports WAV and MIDI - Compatible with Audiobus 3 (including MIDI IN/OUT mode) - CoreMIDI In and Out - AU MIDI output for the on-screen pads User manual available on Ruismaker.com
