Redshrike is a polyphonic synthesizer that combines a resonator designed to make more complicated sound creation and subtraction synthesis with a FM oscillator that creates distortion.

The oscillator has frequency modulation at a wide speed from low speed to the audible range, and it is useful for creating dirty sounds together with the resonator.

The waveform of the oscillator can be morphed from sawtooth wave to triangular wave and square wave. In addition, the oscillator has a 3-voice waveform generation engine internally, and you can make a thick sound by detuning it.

In the resonator, not only feedback amount, but also its pitch can be modulated with ENV and LFO.

The filter has a Low parameter that can boost the bass range, and you can make a heavy sound.

# Note

now with microtuning: So. Much. Awesome.

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.

Deep and distinct

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.

Might be my favorite Iceworks

But they’re all good! Get them all now!
