  • It’s nice

    By Biznatchio
    For the price. The interface is confusing when compared to others. The sound is good but not up to name brands. If you can do with the interface. It’s a good synth. I just didn’t hear the quality in sonic tone.
  • Best synth

    By Nivekevil
    Still my absolute favorite synth in the iOS realm. Sounds incredible, programming is a breeze, and playing is a joy. My only request would be for an AU update! Perhaps that isn’t feasible given the age of the synth, but if it happened I have no doubt Casini would end up on all my tracks.
  • Great Synth

    By Rato1244
    What a great synth! I had been on the fence about this one for a while now but finally decided to buy. All I can say is it has far exceeded my expectations and I am enjoying it very much. I agree with others that it has a 80’s vibe but I can tell it will work well for all forms of music! For those that like to edit their own patches it is all there and then some. And for the price you won’t be disappointed. One of the most underrated synths in the App Store in my opinion. The best six bucks I have spent in a long time!
  • Decent sound, poor knob response

    By Awesome synth
    I have tried to like this synth, and find it frustrating to work with because parameter controls simply don’t respond the way they should respond. The is some nice sound generation, but that’s not enough for me when I can’t get it to do what it’s supposed to do.
  • I'm so glad this exists, and now it has proper ring modulation!

    By Korg Fan
    This thing costs six dollar, but it is GOD compared to Sunrizer and Magellan. It's like an Alesis Ion, but it is only monotimbral (unfortunately). Three oscillators, 6 LFOs, 9 EGs, 2 filters, and a flexible arpeggiator! Did I forget to mention that it also has two oscillator syncs and ring modulators? There are even unique things such as waeshapers, 8 bit waveforms, and FM is now a waveform. That's right, you have up to six operators of FM synthesis! Not only the specs are insane, but it sounds very modern and unique. It sounds so awesome and plays so awesome that I keep coming back to this app. The funny thing about this app is that it took about three years for someone to notice that the ring modulators were not working properly. The only one that noticed this problem was me. I thought the ring modulators were simply oscillator mixers until I contacted Cassini about the problem, and they figured out what caused it. Now I can use it properly! Also,
  • Audio unit?

    By Strizbiz
    Great since day one, the one thing I'd love to see is this as an audio unit for iOS, iaa and Audiobus are great features but imo audio unit on iOS is the future of audio production on the iPad, I hope to see all developers who embraced Audiobus and inter app audio get on the audio unit train too.
  • One of the best iOS synths out there

    By AvengerPod
    There are so many great iOS synths (such as Sunrizer for supersaw or Magellan for dual-layer patches or Thor for all your Reason patches or Animoog for poly aftertouch...) but I've made dozens (50+) of patches on Cassini because of its reasonably friendly user interface and its winning architecture: it's basically a subtractive synth with three oscillators (which can also be FM pairs), a programmable arpeggiator, and a delay. Layering saw/square/PWM/FM gives all sorts of great sound capabilities, and there are a bunch of LFOs and envelopes. Although you can do the most of this (and more, for example phase distortion and supersaws) with Thor, Cassini sounds great and is easy to use. It's one of my go-to synths on iOS that I keep coming back to. The arpeggiator makes it great to play live as well. My only complaint is having to buy it twice for iPad and iPhone - you'll really want it on both platforms so you can have it in your pocket. Oh, and I wish it accepted polyphonic aftertouch...
  • Needs Midi Learn

    By boldstandard
    This is one of the best sounding synths on the iPad. I love the aesthetic look and feel of the app. The one thing it really, desperately needs is a "Midi Learn" function. There are only 4 knobs that you can assign to be controlled by an external midi device, and they are stuck on fixed CC#s. For a synth with as many pages and parameters as this, *all* of the parameters really need to be assignable to your midi controller so you can have everything laid out in front of you in one place. Other than that I like it a lot.
  • sick!

    By Gs2501
    this app is sick!!! the best so far...and for the price it cannot get any better.
  • Well done!

    By kk100
    It's a versatile synth with lots of power and flexibility. 3 Osc, and multi LFOs, Envelopes etc. Excellent delay effect. My only demurs are small, the patch list always resets to the beginning as opposed to where you left off. The signal path could use some more complexity. Otherwise, very nice sounds and easy to use!
