Hi!
If you want an all-in-one overview of how wavetable synths, resonators, granular synths and FM/multi-operator synths work, this is the video for you...
Believe it or not, I set out to make my videos as short as possible, and yet this is my longest ever - there was so much to cover in Waldorf's Iridium - this is the best I can do without leaving anything important out.
Iridium is the desktop version of Quantum, and Iridium outdoes it in many ways (until perhaps Quantum catches up with a firmware update). Really 5 synths in one, it's quite an experience to use, because so many synthesis timbres and engines are so readily available.
Is it perfect? No, but it's probably the best implementation of a usable interface that gives access to so many features and timbres.
I hope you find this useful!
All my best,
Ziv (getting excited about resonators on youtube as "Loopop"...)
