Syndt is a high quality polyphonic synthesizer with a lot of possibilities. The oscillator waveform can be morphed between pure sine to pure square and supports alternation of pulse width. Both the shape and pulse width can be modulated by two independent LFOs. Finetuned low pass and high pass filters combined with a separate filter attack setting (optionally based on velocity) makes possibilities to create some raw and interesting sounds. The additional LFO can be shaped exactly as the oscillator, and optionally controls filters, gain and pitch (using a modulation wheel or just automatcally). This LFO can be synchronized to a AUv3 host. Globally there’s a nice stereo chorus, ping pong stereo delay (that also can sync to a AUv3 hosts bpm) and EQ. Key features: * AUv3, works with AUv3 compatible hosts like GarageBand, Cubasis, Auria, AUM etc. * 70 professionally made presets * XY pad based oscillator and LFO (PWM on the X axis and morphs between sine and square on the Y axis) * Independent mini-LFO (sine only) for each axis of the oscillator XY-pad. * LP / HP filter with resonance * LP Filter can be velocity sensitive * LP Filter has an optional attack time * LFO can affect LP filter, HP filter, gain level and pitch * LFO has an optional attack time * LFO can be syncronized with an AUv3 host (AUv3 mode only!) * Ping pong stereo delay (optionally syncs to host) * Stereo Chorus * Three band EQ * Legato mode with glide speed parameter * Pitch bend range OBS! Syndt oversamples the signal and uses sophisticated DSP features which makes it consume quite some CPU. An iPad AIR 2 or better is recommended if you’re planning to use many voices simultaneously.

But as others have mentioned, it’s difficult to see. I don’t know if it’s the color scheme, but I do think that one fix might be making the control interface the full with of the iPad. It wouldn’t ruin the aesthetic, but it would give a larger amount of space that would make it a little easier to view. Regarding the sound: it is very much a virtual analogue but tends to be more on the polite side. I’m used to using hardware and in some ways this reminds me of a the Novation Nova. Syndt has an elegant sound that tends to be less intense than the more brash American synths. I mean this this in a good way. You can get pretty intense with it, but its sound comes through as a more polite version of analog which if I’m honest, I like very much. I wouldn’t have bought a Nova which were not inexpensive back in the day. I wouldn’t cite the comparison if I didn’t think it was a great sounding synth. I would have liked a few extra patches, as I tend to look for a patch that is somewhat similar to what I like, and then start working from there. Another thought which I first saw on Korg’s Radias were starter patches meant to help designers find a type of sound, and then dial it in to their specific needs. I think that would’ve been a great feature here and in general any synthesizer, I also would’ve liked to have seen a randomize button. There are some really nice designs that incorporate intelligent randomization. Overall, a really great synth. More and moreas I discover. Klevgrand’s designs and inexplicable “feel” which is an intangible as you aren’t moving physical controls. But if you keep making synthesizers like this, I’m going to be buying and making up for lost time. One last compliment : I find your interfaces to be pleasing aesthetically and functionally. Recommended ### 5/5 — Simple and lovely *2023-02-02* Sounds great with minimal tweaking, which is good, because there are not so many options to tweak. Sometimes that’s exactly the kind of synth app one needs. This one rides its simple design and great sounds right into the music. A companion app allows a vector-synthesizer-like combination of presets, which adds a couple of extra ways to complicate the sounds. Being an old entry on the platform, with a number of revision cycles, Syndt performs reliably well. Plus, the price is reasonable. If you’re looking for something like this, you have come to the right place. ### 5/5 — best synth on the market *2021-12-12* amazing developer please update the brus and grand thks ### 1/5 — Not working *2021-11-29* App opens with keyboard and blank screen, when anything is touched, app crashes ### 5/5 — アナログ系の音、上質な音質 *2017-06-05* パラメーターに癖はありますが、アナログの上質な音のシンセ。midi ccなどにかなり対応しており、頑張れば外部から細かいエディットも出来るらしい。グライドが変化する前に音が切れてしまうなど細かい部分はあるが、音は素晴らしい。 ### 4/5 — Much Better Than Their Recent Releases! *2017-05-31* Klevgränd's other releases in their "Kanvas" series of apps have been pretty abysmal. But this release is a welcome departure. A much better sound coupled with a lot more control over that sound sets this one apart from Baervaag and Pads. Both of those are so bad, even the developers couldn't make presets that sound good. ### 5/5 — Marvelus *2017-05-21* MarvelUs sound 🦁 But, some nasty interruptive feedback, now and then....👾, while applying Release..... ### 3/5 — Needs legible labeling *2017-05-20* Syndt sound nce enough, but the labels are in like 1/2 point type. On an iPad Pro, 12.9” model, I need strong reading glasses to see what the controls are. I understand that KG has a minimalist design philosophy, but part of minimalism is utility. Can’t see a thing. Interestingly, I tried to print out their 4-page “manual” and it squeezes and shrinks all four pages onto one piece of paper. What are these people, like 9” tall with enormous eyes? Hope they correct this in a future update. It has potential, but the illegibility makes it a pain to play with. ### 5/5 — really great synth! *2017-05-19* Just got the manual with the cc values, thanks!! Now to connect this to the KRFT beta with midi, moohoohawhaw! **Developer response:** There's a manual available at the product web site.
