First off I respect Yonac immensely and always support their products. Tonestack and magellan are two of my most used apps. They run brilliantly, sound amazing and are incredibly cpu efficient. Kauldron is definitely going for a very punchy, detuned and saturated sound --which if that's your bit then I think you'll be very pleased indeed. The tone sounds more "aggressive" than magellan. I misjudged this synth at first and didn't realize how deep it was. Really blown away and it offers stuff sonically that I didn't realize as brilliant at first. Now my complaints. Magellan jr had a much larger sonic palate in my opinion. The patches in kauldron (including my own experimenting) sound more niche to me. Also most patches sound as if they're going thru a cab simulator which could be a bad or a good thing depending on what you want. The other thing is magellan had more options in terms of fx and also multiple filters routing etc. But it is a different beast that I have grown to love in a different way. Still hoping for megallan 2 tho!The other complaint is that the new spawn has a basic mode with no PAD, LEADS, BASS options and then a very confusing somewhat unpredictable advanced mode. Not really sure what any of the controls or modes mean even after using tutorials. Autonomy vs variation? Please relabelAll around this this synth can produce some really unique sounds I haven't really heard anywhere else. Keep em coming yonac!

Even at a multiple of the $3.99 into price, Kaudron is a powerhouse of an iOS synth, with a boatload of tone generation, sculpting and performance features. It sounds THICK as a wall made of iron, tons of analog vibe, deep programmability, excellent AU implementation, tons of presets, and did I mention it sounds as thick as a planet made of marzipan, concrete and diamonds, with unlimited musical possibilities? I pretty much buy whatever Yonac releases, but this one has to be the most effortless purchase so far. If you're into iOS music making, don't even hesitate, get it, you will NOT regret it.

Kauldron is a great standalone iOS synth. Unfortunately, it’s effectively useless as a plugin due to a bug that I reported over a year ago. When loaded as an AUv3 (I’ve tried it in BeatMaker 3, GarageBand, NanoStudio 2) with a MIDI keyboard connected over Lightning, Kauldron doesn’t conform to the standard behavior of only receiving MIDI notes when its track is selected. Instead, it receives notes regardless of the current track. So if you record a bass line with Kauldron and then try to record a lead with Zeeon, Model 15, or any other AUv3, your lead also triggers notes on Kauldron. As I said above, I reported this bug over a year ago, and never received a response. It’s disappointing because Kauldron sounds great! I’d love to use it in my iOS production, but I can’t with this workflow-breaking bug.

Though it looks like a simple synth at first glance, it can deliver a good range of sounds. I wouldn’t say it’s my fav synth as it’s hard to judge, but it’s definitely in a group of my faves.Efficient, has a character, easy/pleasant to use, good sound quality, good presets management (can create banks and rearrange slot-based patches). Has AUv3.Another excellent synth from these guys is Magellan 2, both are must-have, imho. Very pleasant to use, feels like hardware.
