My goodness what a fantastic sounding synth, the more I delve into making presets the better it gets. This is definitely a “must have” synth ### 5/5 — Great low-cost intro to synthesizers. *2025-07-28* This has been around for so long I almost avoided it for that reason alone but needn’t have worried, it all works. This is compact and so you can layer it up even on a relatively low-powered device. Good for exploring how sounds are created from scratch, for example. And nice presets anyway, still quite a lot of them! (I’d always recommend Apple Silicon though, and as much memory as you can, for iPad-based music, especially if like me you use GarageBand - this baby DAW does do useful automatic downgrading of any VST (Audio Unit) and indeed any, sound source it records, when you come to ‘export’ a final stereo output for example. Yes, that is useful, in that your more complex tracks will play, but the degradation can be 11kHz sampling instead of 44kHz…so you may play an individual track and it sounds lovely, but on GB exporting, it’s all quietly crunched.) ### 5/5 — Classic Analog *2024-02-11* If you’re looking for the more “unique” sound of their other synths this def isn’t for you but if you’re looking for a classic synth sound in Iceworks Format then this is the one. ### 5/5 — Another good one *2019-11-11* Like all of their synths! Great sounding! Get it now! ### 5/5 — Core subtractive synth *2018-11-22* Regular classic synth sounds. Reason for high rating is this is very efficient, low cpu for most things, which is always an issue on iPad versus laptop. ### 5/5 — Great synth *2017-10-16* Vastly underrated synth, grimy grungy baselines to screaming distorted leads are easy achievable and very uniquely sounding. Not to be missed by any iOS synth addict IMHO. ### 5/5 — Cassini and Polysix had a baby! *2017-08-01* I thought this would be just a generic polysynth, but after reading the reviews, I decided to give it a shot. This is a really fun app, and I'm glad it now has AU support! If you like the simplicity of the Polysix, you'll love this. It doesn't sound as smooth or dampy as the polysix, but it still combines what makes the iPolysix fun with the modern and quirky traits of Cassini. ### 5/5 — Great Simple Synth *2017-07-12* With a powerful arpeggiator. Thank you for AUv3! ### 4/5 — Ok.... *2017-05-27* ...unterschätzt... Gut ... man kann viel verändern... ### 5/5 — Bin begeistert vom Lorentz! *2017-05-16* Eine vorbildliche Einseitenoberfläche mit optimaler Ausnutzung der Displayfläche! Erinnert ein wenig an das Konzept vom Roland alpha Juno 1/2 mit zusätzlichen Features wie dem Resonator, dem auch hochstimmbaren Suboszillator (-24/-12/+7/+12/+19 Halbtöne) und einem im Delay verbauten aber für den Gesamtklang nutzbaren zusätzlichen modulierbaren Lowpassfilter. Der Klang steht wesentlich teureren iOS Synths in nichts nach ist dabei eigenständig und generell Geschmackssache. Dabei ganz mein Geschmack, was nicht zu clean klingende Pads und Leadsound angeht! Der Arpeggiator macht Laune! Wünsche: 2. LFO, Tempotap für Liveperformancetauglichkeit mit den Arpeggiator, Modulationsradzuweisung. die maximale Rate des Delaylowpassfilters könnte schneller sein, Audiounit Support. An exemplary onepage interface with optimum utilization of the display surface! The (kind of) Roland alpha Juno concept plus additional features such as the resonator, an uptuneable suboscillator (-24 / -12 / + 7 / + 12 / + 19 halftones) and a delay with additional to modulate lowpass filter. The sound is not too clean, good for pads and lead sounds! The arpeggiator is fun! My Desires: 2th LFO, tempo Tap in the Arpeggiatorwindow for better liveperformance, modulation wheel assignment. The maximum rate of the Delaylow pass filter could be faster, Audiounit Support. ## Frequently asked questions about Lorentz ### What is Lorentz?
