Kronecker is a synthesizer with a mechanism to make sounds many times like a rhythm machine each time you press a keyboard.

In addition to synchronizing the trigger speed to the tempo, you can gradually increase the speed or slow it down after pressing the key. This makes it possible to produce synthesizer sounds like bouncing balls and clockwork toys.

Kronecker has four emitters that emit sound particles made from FM tones and noise. At the emitter you can specify at what timing the sound particles will be triggered. You can also add effects such as the pitch and tone of particles gradually changing.

Particles emitted by the emitter can be processed with two resonators, and you can reproduce sounds like particles jumping on strings and pipes.

Kronecker works not only on the iPad but also on the iPhone. It also supports Audio Unit Extensions (AUv3), so you can plug in to AUv3 compatible host. For each screen size, different layouts are designed to be easy to use and intuitive.

Love it!

Very cool synth combining granular and physical modeling in an interesting way. The sounds do have a kind of same-ness that reflects the architecture, but there are many interesting variations that can be coaxed out of it. I see this as a very specialized product — great to see something new and different. The Laplace synth by the same dev is also excellent.

Poor Interface

This is an interesting synth, but I find the controls much too difficult to operate. There are so many, and they are tiny in size - easy to miss or hit another - or have the iPad miss the swipe.

Most sounds appear to be quite similiar - one would def have to dip into the controls to tune a givn patch to be really different - no so easy to do! Tried for a refund - but Apple says "not elegible'!

A lost $8 I guess... :-(

Most powerful iceGear synth besides Cassini?

While it’s not for analog style sounds and leads, this is basically Mersenne on steroids! You can layer four FM pairs, and each operator pair has its own rhythmic beat!
