Lorentz is not only a live-oriented analog modeling synthesizer, but also has a resonator that makes metallic and aggressive sounds. This makes it easy to create a new synthesizer sound with a resonator added to the sound like an analog synthesizer.

The oscillator has a sawtooth wave, a pulse width modulatable rectangular wave, a sub rectangular wave and noise. You can mix these waveforms at the same time. The filter has extreme resonance and overdrive that violently distorts the sound.

Since all the parameters including the effect are contained on one screen, it is recommended for live performance.

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.

Another good one

Like all of their synths! Great sounding! Get it now!

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.
