Absolutely love the sounds I can get out of Spectrasonics’ Omnisphere. Fat synth basses, warm pads, beautiful textures, fantastic rhythms from it’s arpeggiator, extensive synthesis editing and signal processing. With over 14,000 built-in sounds, audio import/processing, 500+ synth oscillator waveforms, wavetable synthesis, granular synthesis, 57 effect processors, FM/Ring modulation, 34 filter algorithms, performance mode (stacked or layering), 20 oscillators and 8 LFOs per patch, 12 envelopes and substantial HW synth integration it really does feel pretty limitless.
That being said, Omnisphere seems like a bit of a memory hog. It crashed a number of times when using it within Logic Pro X (crash logs submitted). It’s a bummer when it happens but to be fair it appears to be due to switching between Logic files that have a lot of other plug-ins instantiated as well.
I found a really useful course on Lynda.com that helped me get up to speed using it just in time for the Spring Equinox concert and album: Learning Omnisphere 2.
If you want to add an amazing sounding software synth to your set up then this is it!
