The GSi Krill Synthesizer was born from a design originally conceived to work as a mono synthesizer on an embedded processor (RP2040), then it was modified to be polyphonic for a more powerful processor (ARM H7) and finally we thought it would be perfect as a AUv3 for iPad, for those quick and dirty synth sounds you sometimes need without getting lost in endless parameter navigation and menu diving. So here it is, just one screen, one knob - one function, what you see is what you get. Two oscillators, one LFO, one low pass filter, two envelopes, stereo chorus, ping-pong delay, 64 presets. Have fun! ## Key features - Virtual analog polyphonic synthesizer - Single-screen interface - Two oscillators - One LFO - Low-pass filter - Stereo chorus and ping-pong delay - 64 presets ## Recent user reviews (6 of 6) All indexed reviews: https://appshunter.io/ios/app/krill-synthesizer/id6443337049/reviews.md ### 5/5 — Warm analog bass *2025-09-22* This synth is my favourite for warm analog bass, though It has only 2 oscillators. So I usually layer it for a richer sound. It is easy on the cpu so a few instances are no problem. ### 5/5 — Killing is Krill’s Business and the business is good! *2024-09-15* Krill, can not be described or be reviewed! It’s impossible! GSI have outdone themselves, truly one amazingly unparalleled work! If there’s ten synths are being played, it’d take around for you to recognise the sound of Krill in .05 seconds, depending o your sonic appreciating ability. I’d like to convey my deepest and most sincere form of respect for your contribution! There’s actually not any video of krill in YouTube. Strange world. There are two relatively new monsters have arrived in the IOS platform, GSI and Audiothing! Man these two are literally unstoppable and unparalleled force of Creativity and Integrity! It made me so sad that before mine there’s only one review! It’s absolutely alright! Not everyone is able to appreciate the true form of art and aesthetics, otherwise we would all become Mozart! Sometimes it’s better to be recognised by the gods rather than of the ant. We love you GSI! ### 5/5 — Oh my god! What have they done!

Sounds really beautiful at times and really naz’tay at times… other than it being a little 🤔 crude and clunky I really like it!!! I don’t like the preset system tho 🤷‍♂️ ### 5/5 — Top sounding, simple to use synth. *2022-11-21* Nice sounding synth, with a warm analogue filter and feel to it. Although it’s look is a bit simple and unfashionable, I find myself returning to it often, because of it’s ‘sound’, which in my opinion is richer and warmer than most of the other complex and fashionable Auv3 synths out there. Deserves a lot more credit. Ability to sync the LFO and Delay would be a bonus, but for the price, it’s sound is worth every penny. ### 5/5 — On fire 🔥 *2022-09-19* This dev just came out of the woodwork and is dropping some lovely apps ! Great 👍 work! Looking forward to the space echo and any new apps you drop! ## Frequently asked questions about Krill Synthesizer ### What devices does Krill Synthesizer support?
