The sounds that come out of this are outstanding. The best sounding synth i have. It taxes you on the CPU resources, u just have to learn to bounce tracks more to work with it. I would have gave it a 4 because of this, but again the sound is so amazing its a 5. I can't believe izotope no longer updates this.

GUI: The GUI is lovely and very pleasing to look at. It's also very intuitive and easy to use, similarily to Serum. This doesn't just include the spectral filtering tools, but everything, including envelopes, modulation etc. It's also resizable and very customizable in terms of layout. All drag-and-drop, and provides a very nice first impression.

Features:

Spectrogram display - basically a great spectrogram visualizer, can also show a waveform, and both simultaneously. One of its main features is the Spectral Filtering, where you can use different selection tools to select different parts using the visualizer. The selection tools includes the very useful lasso tool, which can be used for some crazy sound design, amongst other things.

Envelopes: Five graphical envelopes, with the normal controls. Can be set with drag-and-drop to modulate almost anything.

LFOs: The same. Easy to use, graphical. intuitive. Same modulation system, same flexibility.

Effects: Not the broadest selection available, but you got the most important ones: reverb, delay, distortion, chorus, and filters. Available both as inserts and sends. Four parameters on each (except the filter), so these are not for the heavy tweakers, but they deliver decent results quickly. As far as the filter goes, you only get to control cutoff and resonance (as well as keytracking), but you have 17 different filters to choose from, so that weighs it up.

Sample layers: You can layer up to four different sounds, and control all individually. Master control is also available from the mix panel. Great for making crazy sounds.

Sounds:

The sound library is huge. According to the iZotope website it's at 11GB. Haven't checked myself, but it seems about right. You get some standard sounds (basic synth waves, stuff like that), which are very useful if you want to use this for "non-crazy" stuff, but the emphasis seems to be to cater to a sound designers wishes (as it should). You get objects, enviromental sounds, toys, modular synths, to mention some. Love the sounds, and it's definetely a selling point.

Sound:

As good as I expected. Not meant to be a sound-enhancing tool. but can't fault the sound. Had more problems with clicking and other audio-related problems with other software. Also includes the brilliant Radius RT, a stretching and pitching algorithm/mode that lets you (as far as I have discovered) play sounds and changing the pitch without changing the tempo. It's not perfect, but I haven't encountered anything better.

Performance: This is where things start to look a bit worse. While it's not killing your CPU from start-up, it can get nasty after a while. Got almost 50% CPU on my haswell i7 on some of the more complex patches. Expect bouncing to audio if you are going to use this heavily.

Price: While you can get it on sale, I think a $250 asking price is a bit too much for casual users. For sound designers it will definetely be worth, but for "normal" producers and composer, it may be too much for a "crazy noise machine". In other words: it depends on who you are.

Conclusion: The CPU perfomance ruins it a bit, but otherwise, this is a unique and solid piece of software, which for the right users, will be a dream come true.

Just cool and cooler as version 1 - a nice tool to fiddle with any audio to build pads and long lasting sounds, but is even a handy tool to sound design short "crazy" stuff non heard from (and not possible with) any synth before. Like it or hate it... ß)

Just purchased Iris 2 recently and was rather pleased with the modulation matrix.

1. Use a future computer and a fast read/write SSD!!.

"We chose to ensure audio fidelity and sonic possibilities are the top priority in Iris 2,
anticipating faster and more powerful computers will continue to be developed in the future." - Iris2 ref manual.

Even though having only 5 LFOs and 5 ENV, it was pushing the CPU and ASIO drivers hard on the new patches I created. Typically I like to utillise all the sample slots, have an LFOs modulate type Multiply LFO for FM. Assign multiple params to a macro knob, use lots of macro knobs for pitch shifts and sample gain levels, also simultaneous changes of effects params. I end up using all the effects. I guess the newest most powerful machine is required to run the standalone program. I haven't used it in my DAW yet, most probably would do that after a few more sounds patches are done. Ironically, I bought Iris 2 based on the idea of a sample playback VST with unique filtering options, it would be less CPU and disk intensive.

2. Sample and sound playback useful for soundscape creation or soundtrack production. eg. Post production.

"Every pool can load a sample or classic oscillator waveforms
To increase flexibility, the Sub section from Iris 1 has been replaced with a sample pool that
allows you to load any sample. / Every pool can load a sample or classic oscillator waveforms

Filters are good, Warm Synth, Screaming Peak and Tokyo LP been useful for my sounds, just requires careful use of resonance.

Still wondering if I can create or import my own LFOs into IRIS2. Went through the manual, doesn't seem to say anything about that.

The resample option changes pitch of the original sample, but it plays back faster. Really doesn't work well for voice samples. Pitching with Radius RT has limits, is resource intensive. Surely was expecting more from iZotope especially after how well they presented the new version. Having the sound of the chipmunks a fifth or octave up brings me back to the days of early portable samplers, better suited for hand claps and percussion. Even back then key ranges could be assigned to certain samples or individual keys. I understand this is 2015 and we would expect options for layers or loading SFZs or maybe triggering multiple pre-sampled wav or aiff files across the keyboard.

3. Working in a box of boxes maybe. It does simplify sample sound shaping playback, with some effects to add body to sounds. That's about it.

"KEY FEATURES
i) Build your own synth: Create sounds that are completely unique by layering up to four
different samples
ii) Shape your own sound: Develop expressive, dynamic, and evolving musical sounds with
the powerful and flexible new modulation system.
iii) Draw your own filters: Draw, select, and isolate sonic components from each sample layer
using iZotope's award-winning RX Spectral Filtering technology.
iv) Define your sonic signature: Load one of the hundreds of fresh and inspiring presets and
immediately tweak the most important parameters with eight Macro Controls available
right in the preset window." - Iris2 ref manual.

I just couldn't agree with the part of building your own synth. I believe its just a sample playback software that you
a) LOAD samples or single cycle waveforms,
b) apply MODULATION to parameters. I don't see anyway to morph waveforms unless via basic FM, AM.
c) SHAPE sound via specific filtering, isolation.
d) USE presets supplied or sold and tweak them with the eight Macro Control.
e) You can't edit the Sound files in IRIS2, you need an audio editing software that displays zero crossing clearly. Especially important when dealing with loops.

IRIS 2 does feel like a tool that plays samples with basic loop functionality and applies effects and modulation. The spectrum analyser window is helpful but is best left tucked away to reduce CPU load.

i'll just try to work within the box, this 32 polyphony tool box that requires a future computer.

One of the most versatile and surprisingly creative synth on the market. Designing patches on the spectrum image (almost as in a photoshop UI) is intuitive and easy and, most of all, gives the user a different point of view, which often results in very original sounds. Automations, macros, playback and loop settings, together with the graphic design you can make directly on the sound file's spectrum, give endless possibilities to musician's creativity.
