I understand and sympathize with the software people. I use software and various plugin “synths” - and they do a very good job for what they are. The fact that you can get a decent filter emulation from a pile of bits in a minor miracle.
The creamware and arturia softsynths are very convenient and have a pretty high-quality sound. But they lack the tactile interface, and are fairly uninspiring. I find myself glumly flipping through presets until the boredom ratio makes me go outside and play.
I agree with goldphinga. Set up a Minimoog next to your midi-controller and software, and play.
Besides the latency of plugins (which has improved vastly over the years but still is not quite there, unless you have a $3,000 computer) there are subtle but important sonic qualities to an analog synth. And Moog synths have the best sounding, most musical filters out there.
Sitting in a mix, the average person can’t hear the difference. So it might not make a differnece to you. But musical instruments aren’t for the consumption of dilletants, or for burying in a wash of other sounds. They should stand up on their own. A Moog synth can, just like a guitar, be a musically complex, attention-holding solo instrument.
Slowly tweak the filter cutoff on your favorite synth plugin. Sounds OK, if it’s a new, expensive hi-res conroller/plugin combo. (If it’s old, like mine, it shows its digital seams.)
Do the same thing with a Moog from 1972. It sounds so much smoother and harmonically rich. There is a network of behavior that cannot be completely modeled. It’s sonic infinity.
Having said that, the best virtual Moog in my opinion is the Alesis Ion/Micron. Sure, it’s hardware, but much attention went into the Moog filter emulation. Not perfect, but nothing ever will be.
Except the Moog. The Moog sound is the Moog sound. Dig?
And doing thigns like maving a poly mode on a minimoog is a convenient violation of the spirit of the thing. Those companies should have poured the system resoruces into making the mono modes a much higher quality.
