Free update installable on Apple Silicon Mac
If you have already purchased this App on your iOS device, you can install it on your Apple Silicon Mac for free.

Lorentz is not only an analog modeling synthesizer, but also has a resonator that allows you to create metallic and distorted sounds. This makes it easy to create new synthesizer sounds with a resonator.

Unstable and fluctuating oscillators have unisonable sawtooth waves, pulse width modulated square waves, sub square waves and noise. You can mix these waveforms at the same time. The filter has a self-oscillating resonance.

Core subtractive synth

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.

Lorentz is a BEAST

I own a LOT of iPad audio apps and well over 30 iOS synths. Of those, there are only a handful I would use for professional recording, such as Moog Model 15, Animoog, Korg ARP Odessei, Nave, and a few others. I would put Lorentz in that elite group. It can sound like a Jupiter 8 or a CS80 or even a 303. The routing is amazing… the filters are top-notch (a full LPF on just the Delay)… and that resonator just fills the sound with harmonics. Lorentz does dark and gritty very well too. It has all the MIDI options needed as well as Link. Did I mention it has dual envelopes? The other IceWorks synths are great too but this is my dog right here.
