This is my favorite purchase in a very long time, and certainly the best buy at the price. If you are the kind of person who likes to load Omnisphere and play "Glorious Guitars" for hours, then this is for you. I was up until very late last night playing this thing. Essentially you can combine two multi-sampled acoustic stringed instruments or a string instrument and a luscious pad. Either layered or in a split. Some of these sounds include: American zither, Felt Upright, Folk Harmonics, GuZheng, Hammered Dulcimer, Hammer Piano, Kantele, Mand-Doublin, Mandolin, Multi-Zither, Piano HI, Piano LO, PianoOctaves, PianoBass, PianoAttack (Tack), Piano Plucks, Piezo Guitar, Pipa, Pluck Upright, Psaltery, Ronroco, Seagull, Sitar, Ukudouble, Ukulele, Amped (elec guitar), etc. etc etc I went crazy all night doing that. And then a lot of beautiful, ethereal pads, which seem to be derived from the acoustic instruments, and have names like AcuTrails, and PipOrgan, Psaltervibe, CloudMonics. Among the many things in this are convolution reverbs and granular synthesis and the like, so if you like Seurat, you will love these sounds. I just worked with what Audiofier considers the "Simple Start" That could keep me going for the rest of my life. I can just make adjustments to the various effects for sounds I like. But after that, this is something like a Tantra-like thing that can twist and mutate the sounds in trillions of ways. It has a sequencer, arpeggiator, crystal (pitched delay lines), reverse, and you can create step effects for filter cutoff, resonance, distortion, formant filter. 180+ effects. You can learn all about that in the video, and I'm sure it will be a monster for composers. It is so complex, that this is intended as a hit-the-randomize-button-and-see-what-you-get type of instrument. It's set up that way with a 1000 undos, in case you didn't save that thing you loved 973 randomizes back. There isn't a single preset that comes with it, just snapshots that are essentially templates for you to begin randomizing. Audiofier has two other instruments that are set up in the same way. ABSTRUNG - Strings VESPER - Bells and Twinkly Stuff AERKORD - Bowed Strings (Orchestral, guitars, ethnic), Woodwinds (Duduk, Kaval, Bamboo flutes, Ocarina, Gralla) and Female Voices. I love this so much that I think I will pick up VESPER and AERKORD too. It would be amazing to load these three up as multis, although i suspect this would tax system resources. Maybe a better idea would be to use the stringed instruments with another VI. I bet it would work beautifully with Seurat. Do I think this is worth fifteen bucks? Hell yeah!
