Kauldron is where classic warmth meets Artificial Intelligence. One of our toniest and punchiest synths, Kauldron features a completely new analog modeling technology. The full spectrum of rich synth textures is bolstered by the groundbreaking SPAWN intelligent preset generation system that allows new patches to be created at the touch of a button. Abounding with pure hard-hitting tones, Kauldron requires little to no FX or production gimmicks to sound big. Kauldron is designed with modulation and fine dynamic control in mind. The two fully-featured LFOs and the mod envelope combine with a wide variety of MIDI learnable controls to manipulate multiple parameters. Everything is easily set up in a clearly laid out ‘mod matrix.’ The dual XY-pads can be used for controlling modulation or a wide range of synth parameters. MIDI aftertouch can be routed via the matrix for even greater control over expression and tonality. Kauldron also debuts the next generation of our Artificial Intelligence preset creation system, SPAWN². Completely reimagining the groundbreaking SPAWN algorithms in our hugely popular Magellan, the new SPAWN² gives you unprecedented control over generating presets. In the expert mode, you can accomplish anything from subtle ‘variations on a theme’ to bold new sounds. In the basic mode, where Kauldron does all the thinking, you get preset after usable preset with just a touch. This is not simple randomization: it is the power of A.I. put to benevolent use! Kauldron also includes its AUv3 plugin version so that you can seamlessly run multiple instances in your favorite DAW. Powerful arp with both live & program modes; comprehensive MIDI features with effortless MIDI learn; over 900 presets; recording, sharing, these are just some of the features brewing inside Yonac’s Kauldron.

DM2 is a synthesis-based drum machine with a dedicated graphic editor, for the creation and manipulation of sound . Yeah, blah blah blah… let’s start again. Your lucky stars have all aligned. There are blue skies and smooth sailing ahead. So throw your worries away, and get ready for DM2 to bring endless fun and blissful joy to your face. Your colleagues and friends will be amazed at the new you, wondering how your fingers produce such ravishing beats. Strangers may come up to you in cafés and ask you, “That rhythm sounds like heaven. How do you do that?”. Life can be good, so tap your feet, shake your head and let’s start making some groovy electronic beats with DM2. DM2 has been made by the core team that brought you DM1, one of the consistent best selling drum machines for iPad, awarded with an Apple Design Award in 2012. If DM1 was cool, DM2 is ice cold. Now let’s talk business. DM2 contains 6 pages. Each page does 1 thing. Or perhaps 2. A BIG, BIG STEP SEQUENCER. 16 or 32 step patterns. Or why not 7 or 25 steps? Or even polymetric tracks (poly what? no worries, just a fancy word for complex rhythms, yet super easy to make). And while we are at it, steps can also be singles, duplets, triplets or quadruplets for even sophisticated rhythms. Again it is all about drawing funny objects to make funky beats. THE DRUMS PAGE. Where the sonic magic happens. Six touchable graphs to create sounds. Oscillators, LFOs, filters, noise generators, all the usual suspects in a drawable interface. This may look a tiny bit daunting at first, but the beauty is that whatever you touch, you’re not going to break anything. So give everything a whirl, and get experimental. And if you need some inspiration, DM2 contains plenty of ready-made sounds too. THE PADS PAGE. Maybe you prefer finger-drumming? Sure, go ahead. Press REC and record your rhythms. Of course, there is an automatic quantize function, so that you’ll never miss a beat again. THE MIXER PAGE. Big and beautiful, it will transform your iPad into a professional mixing desk for the price of a magazine. THE FX SECTION. A powerful Effect processor. Just switch everything on and see where it takes you. THE SONG PAGE. Last but not least, put all your hard work in the previous pages together in a shiny song. DM2 is fully MIDI-mappable with more than 130 assignable parameters that can be controlled by an external MIDI controller. Finally, because music makes the people come together and mixes both the bourgeoisie and the rebel, you can export your creations to share with the world. DM2 is packed full of save/import/export abilities. Ahh, the wonder of modern technology! For anyone interested in immersing themselves in some tech specs, please see below. Otherwise, feel free to stop reading now, grab your copy of DM2, and get jamming.

Verdict

The call

The clearest difference is update cadence: DM2 The Drum Machine at every 6 weeks against Kauldron Synthesizer's every 49 months.

On ads, in-app purchases and monetization model there is nothing between them.
