  1. This is the most powerful synth I have(iPhone version though). This dude, more than any one, deserves your $2,99. I love it even in iPhone, which is so full of synthesis now that I fear it might crack the glass of my screen.

    I could, and will, buy iPad just for this!!!

    This is the new king of iOS synths!

  2. Been messing with the iPad version for an hour or two. Pretty powerfull and the price is great. I’m not sure it will dethrone Animoog or Sunrizer but I think it will occupy the same territory. I’ll add a little more in a few days when I’ve messed with it and tracked with it more.

  3. I have the iPhone version as well as Xenon, which I use all of the time when I’m stuck doing something horribly boring. Great apps, both of them, and at such a good price

  4. I have Sunriser and Animoog. Have been waiting for the iPad version of this for ages!

    The Synth Trinity will be soon complete!

    Guess what I will be buying tonight? 🙂

  5. I love Sunrizer, but after adventuring in the vastness of the Cassini, the Sunrizer has felt restricted. Well, I have a library nearing a hundred own sounds in Sunrizer, and not a one complete Cassini sounds yet.

    I have had a habit of making one sound each night with Sunrizer, and I often end up making 3 or 4, but the Cassini is so crazy, that I consider its sounds as longer projects. Cassini is fast becoming my favorite synth.

  6. Do we really need to have an ipad to create music nowadays ?

    Seriously, is it impossible to create the same sounds with all of the existing VSTs or hardware synths?

    1. No, you don’t need an iPad to create music. However, there are those of us who enjoy being able to create music wherever we are, and the greatly portable iPad facilitates creativity-on-the-go. I enjoy being able to sit outside and create music. You might not.

    2. You don’t need to make music at all.

      I enjoy making music, and for me the direct, and more musical control is more enjoyable, than VSTi.

      I use Analog synths, digital synths, VSTis, iPhone, iPad, acoustic instruments and my own voice. I prefer analog, but right after that comes iPad.

    3. thats like asking a mechanic if one screwdriver isnt allready enough 🙂

      you cant question using more then one tool, and even if you do everything in logic f or example, you would have to take a macbook air 11″ or similar around to have the portability of an ipad, and touch controls ^^

      the ipad is just the perfect note pad, for virtually every creative field available, and with apps costing around 3$/€ there is absolutely nothing compareable out there.

      if you dont like apple, its ok not to buy it, i would not buy a microsoft tablet either, but lucky as i am the company i buy my computers from, made a tablet, so iam buying it 🙂 bought it 🙂

      and i seriously hope, that aft every other company brings out a tablet, so apple looses some market share, and gets back where they came from: serving pro users

      and first thing would be to kill fcpx 🙂

        >and first thing would be to kill fcpx

        Man, I just totally disagree with you! I think you need to update your view of what a “pro” user is. I don’t edit feature length films, but I do make videos regularly for promotion and training, and tools like FCP are unbeatable in both power, price and ease of use. I learned editing on older “pro” systems, so don’t think I’m uninformed here. And let me tell you what… there are far more people with my needs than what you consider “pro”. If you are whining about tools like this it’s because you are no longer special just because you own the only powerful tool in sight, and now anyone can do with speed and ease what you used to do, and you will from now on have to stand on what you can contribute rather than what you own/use.

        And yeah, Cassini is a really great synth! :0

    4. >>> Seriously, is it impossible to create the same sounds with all of the existing VSTs or hardware synths?

      Of course not, but people raised with cell phones often see an actual keyboard as a mere sample trigger rather than something to learn to play fluidly. iPads are very seductive and can easily add to that view. Its far easier to peck at a pad than it is to develop actual muscle memory from woodshedding. I’ve witnessed quite a bit of live music and while I’ve been impressed with a lot of it, its always been the real-time, taking-a-risk players who really astounded me. Being able to sweep through 4 parameters in real-time with one finger on a pad certainly has several cool uses, but I have yet to be as impressed by that as I am by someone who can sit at a piano and pull off a full 5 minute piece. My favorite so far: people who do both within a song, which brings both the iPad and the keyboard work to REALLY killer heights.

  7. And this is the part where I regret buying an android tablet. I’m probably supposed to try and argue that android is better, but the stuff iOS can do blows it away. Congrats!

  8. Another impressive iPad synth.

    Animoog and Sunrizer are my two current favorites, but it looks like Cassini and Magellan may be joining them.

  9. Good sounds. Pretty intuitive. It’s a little wonky with the controls, i.e., I’ll have to get used to how the knobs work, and some patch changes seem to take more than one press (or there is a delay). But it does sound really good, and to my ear it has lots of “personality”.

    For those of us who have lived to see the large arc of hardware synths, this interface is visually evocative of a certain era.

    I recommend going to the developer site and watching those short demo videos. There are a few big AHAAAA!! moments.

  10. After spending a few days with this app I am regreting it. Magellan blows it out of the water both sound wise and in terms of apperance. It is nowhere near the league of Animoog, Sunrizer etc.

    Lots of knobs doesn’t equal good, especiialy when the knob control feels like crap. Save yourself the money and spend it on magellan or sunrizer if you want a synth in this proce range.

  11. I thought this looked pretty cool so I snapped it up but I had bought Magellan only a couple of hours before and Cassini sounds a bit lame after that. Also had a crash within a few minutes of using it, and there seems to be a bug in the arpeggiator – does anyone else get this??:
    1. pick a sound, I am using A01
    2. go to the arp screen, activate arp, press 4 keys and wait
    after a few seconds the sound cuts out. sometimes it comes back, sometimes the pressed keys become stuck on and you need to de-activate the arp to release. I emailed the developers and did a de&re as suggested but am still getting the problem, apparently they can’t reproduce it at their end…

    1. Yep, exactly the same problem here as pantsfdeath. Except that on mine the app completely hung the first time I did it (sound stopped, no buttons work). But subsequent times i’ve had the full range of symptoms that you report. iPad 1, iOS 5.1.1, no other apps running, freshly rebooted, using internal speaker.
