Типа наслаждайтесь и креативте их сами. Крутишь - крутишь эту хренову тучу ручек и настроек, только тратишь драгоценное время, а звук только всё хуже и хуже от тех немногих стандартных пресетов, за редким исключением. Короче как я понял - как раз этот набор стандартных пресетов, с горем пополам, который смог сделать разработчик, и есть тот максимум приемлемых для звукозаписи звуков, который можно добиться от этого синта. Разочарован покупкой. И сделайте уже наконец больше нормально отсортированных пресетов. А уж потом мы их чуток подкрутим, если надо и если время на это будет. ### 5/5 — Ugh so dirty! *2024-03-07* First of all this synth looks awesome, love the red colour scheme. Tasty 2-OP FM, great resonator (iceworks speciality) with positive feedback that is stringlike and negative feedback that i would describe as bell or metal like and a screaming lowpass filter. Oh yeah and distortion!!! how nasty! 🤟 Red Shrike is chockfull of character and very inspiring, I made: spaced out pads, bold basses, otherwordly keys and some very corrosive acid patches with Red Shrike, it's really fun! ### 5/5 — Angry Bird Synth *2024-01-28* Spoiler alert: This synth is AWESOME If you enjoy creating your own patches, *nothing* beats the Iceworks synths. Period. End of story. I could easily end this review there, but I won’t. This bird (a shrike is indeed a bird) can make some of the angriest sounds imaginable (making red the perfect color for it ) but also can chirp out some really spacy sounds as well. This is unlike any subtractive synth on IOS, in that it mixes a traditional analog filter with a fairly substantial FM section and the (in)famous Iceworks resonator. You can make some pretty cool bass sounds, some atmospheric synth patches that would make the late Richard Wright shed tears of joy, or squelch out some pleasantly harsh sounds that would make the folks in 80s Detroit beg for OCP to take over (if you get the reference, you with the No-Prize) In short, you NEED this synth … ### 5/5 — KILLER SCREAM! *2022-12-06* It‘s just an amazing piece of synth tech! I love it‘s resonance, fast switching, soundscaping by turning just a knob and BANG! Sometimes it feels like a living creature 😅 Just a BEAST, no doubt: 5/5 🌟 100% RECOMMENDED just as everything from IceGear 🔥 ### 1/5 — Developer non-responsive *2020-04-30* Having an issue but no response from developer. **Developer response:** I apologize for the inconvenience. I didn't receive your message. Could you please resend the email? support@icegear.net ### 5/5 — Might be my favorite Iceworks *2019-11-11* But they’re all good! Get them all now! ### 5/5 — Awesome Lead Synth *2019-07-05* While Lorentz makes great analog sounds, Redshrike makes some really neat leads, basses, and even distorted pads thanks to the fm and versatile filter! ### 5/5 — now with microtuning: So. Much. Awesome. *2018-07-11* I don't know if I should say this out loud, because iceWorks is a one-dev show, but what a responsive and hard-working show they are! I asked for custom tuning.. and within a couple of months, here it is! Redshrike is my favorite of all the iceGear/Works synths: like the others, it takes an approach that is relatively unique in iOS synths--physical modeling of resonant bodies--and takes it right up to its screamiest, dirtiest, scariest limits. Resonant modeling is under-explored as it is, and iceWorks is filling in a very large gap and doing it very well. Redshrike has a vast range: from sweet, quiet, percussive bell-like sounds to enough monstrous infinite sustain feedback saturation and crunch to make men faint, women cry, and the rest of us jump up and down in sheer joy. The early versions had some glitchy AU problems, but as far as I can tell those are all worked out now. I'm running iOS 9.3 on an iPad Mini 2, and Redshrike is reliable and just as loud as I need it to be. It runs great in AUM, as a standalone, and in Audiobus. And now we can play with just intonation, meantone scales, Pythagorian scales--any twelve-tone scale we want. Me, I'm never turning this thing off. ### 5/5 — Deep and distinct *2018-06-16* I’m just diving into this, but it’s a winner — it has its own character, distinct from either analog or FM synths. The resonator is unusual and I’m still trying to wrap my head around what it does. So many interesting bits like the pitched, digital and glitch noise styles; the deep filtering options in the delay; and the most customizable arpeggiator I’ve ever used. This is a steal at $8. ### 5/5 — Another winner from IceGear *2018-05-18* Redshrike is my favorite IceGear synth and I think the most complete synth they have made. You can manage to create a massive array of sounds with Redshrike from ethereal pads to deep percussive bass. As usual their dynamic arpeggiator is included and it’s auv3 and IAA support is also included. Must buy for iOS producers. ## Frequently asked questions about Redshrike ### What kind of sounds can Redshrike create? Redshrike excels at producing aggressive, sharp, and dirty sounds.
