I will start off by saying that Z3TA+2 is incredible, and it seems quite underrated.
This program has so much versatility to it that enables you to make so many awesome sounds. The waveshaping function is simply incredible. There are up to 6 oscillators, each with different modes such as sync, normal, inverted, and multi. You can't go wrong with 6 envelopes, 6 LFOs, and 2 filters. The envelopes and LFOs can be mapped to whatever you want. The filters have many different types that are not always on other VSTs, including comb, formant, and reso. There is a cool sounding resonance seperation slider, reso boost, and limiter. There is so many different shapes for sounds by default (however if you want a pure wave you'll likely need to import it yourself). There are many effects built into the synth, however they can be quite basic. You can choose if you want to map the distortion to a filter. I won't go too in-depth about the rest, as there are quite a few effects, however it will probably be a good idea to supply your own VST effects.
Z3TA is an additive synthesizer. Now, because it's additive, it can be confusing at first. When I first loaded this up, I felt like I was looking at the controls of an alien spaceship. The matrix at the bottom can be slightly difficult to figure out at first, especially to one new at making electronic music, but once you get used to it, it is very powerful. You can use it to control knobs within Z3TA+2 with LFOs, envelopes, and other things. You can also use this to keytrack different values and map things to note velocityamong other things. It also supplies you with a curve option, which will exponentially or linearly increase the knob value depending on what you choose. The one thing that I do not like about it is that you cannot modulate specific options in the Envelope (such as attack, amount, decay, etc). You can still automate the knobs in your favorite DAW, so it's not the biggest deal.
All in all, this is some great software. I will certainly use it in many of my songs. I highly recommend this to any seasoned electronic music creater.
Disclaimer(sort of): I am not the greatest music producer, however my abilities are always growing. I learn something nearly every time i start FL. Also, Steam says I have only used this program for 5 minutes, and I will tell you that this is not true. I use Z3TA in FL Studio (as stated before), and to do that it cannot be ran from steam. I have used this program in at least 50 hours of making music from the point of writing this review, with many more spent simply experimenting.
