Query: Mooogy!

I have played around with some of these virtual instruments to find that some of them are quite good-sounding. The Moog series VSTs are somewhat less attractive that, say ARP VST. They all are CP memory-consuming plug-ins that also require sound cards with good latency characteristics (otherwise you have to play the instrument in MIDI mode with a reduced latency, allowing for clicks and pops to appear, and then increase the latency before the recording is mixed down to an audio file). The Moog series have lots of factory settings that mostly out of the range of pleasant and purposeful sounds. It is often hard to use them either as leads or bass sounds, and they need to be tweaked so some extent. Besides, some of the sounds are overwhelming and destroy the rest of the sounds in your recording. If you're after bass sounds, I'd suggest the Arp 2600 VST instead.
