Well in the end I couldn't resist anymore and bought Falcon. Now I hate myself cause I spent over 500€ for plugins this month alone.
What can I say, is Falcon the tool I expected it to be? Yes and no. First of all I'm delighted that it's a great sampler. I thought sampling would be more of a rudimentary feature, but it's not. So I can cross off buying another sampler.
Compared to Serum I'm missing a few things. Still you cannot really compare Falcon to Serum, Falcon is just another league of an instrument.
What I miss most is the possibility to combine certain techniques, like running a wavetable synth through granular. That doesn't work, I kinda expected it would. You can have wavetable, granular, samples and whatnot in parallel as many as you want however.
The noise oscillator is a bit disappointing cause it can't use custom samples. On the other hand you can substitute that just with a regular sample patch easily.
Biggest surprise was the plug oscillator, what a powerful tool, omg!! (<- I usually don't write omg!!11)
So I was wrong before, Falcon definitely is worth it's money, the depth of this monster didn't show to me before. I'd never want to miss it again. And their commercial library, like what? Synth Anthology 2, World Music, ... dude. Some say Falcon doesn't come with enough Factory presets. By default it does come with about 300 presets that sound great and a voucher for other libraries. So you have to be willing to invest more money if you want more patches, I am not atm, but it's certainly justified to charge money for those libs.
In conclusion: You want organic, natural pads? Get a third job. :|
