There's been a ton of talk about Spectrasonic's soon-to-be-released Omnisphere, and deservedly so... it looks absolutely amazing. But I haven't seen much talk about Camel Audio's upcoming synth Alchemy, which seems to tread similar ground with a smaller sample library (to me, that's a plus. I don't have room on my hard drive for 55 GB of samples). Here is some of the write-up from the Camel Audio website:
Alchemy is the ultimate sample manipulation synthesizer. It's a synth powerhouse and yet is very easy to use thanks to its performance controls and remix pads. Just tweak the library of excellent presets from many of the world's top sound designers or dive in and analyse your own samples - it's up to you!
Alchemy features additive, spectral and granular synthesis and resynthesis, sampling, and a very capable virtual analog engine with unison and PWM. You can morph or crossfade between sources. You can import your own samples from SFZ, WAV or AIFF files. A wide range of analog modelled filters are included, in addition to a flexible rack of effects which includes all those from CamelPhat and CamelSpace as well as many new effects such as a high quality reverb. The innovative modulation system is extremely flexible, yet easy to use. Alchemy also features a powerful arpeggiator with the ability to import the groove from any MIDI file for immediate synchronization to a beat.
