I can't believe nobody has mentioned the Memorymoog LAMM? Granted I only had my newly acquired (Mint) memorymoog for 3 days last week before shipping it off to Rudi for the LAMM upgrade, but WOW. Only 3 oscillators would tune, but the sound still melted my butt-hair off. I have played/owned a lot of synths, but nothing comes close to this. I assume it's so slept on because of the reliability issues, but add the LAMM upgrade and you have 18 stable oscillators and MIDI control of every parameter. An 18 oscillator, 6 voice polyphonic moog with that classic filter, modern day stability, with full MIDI? Can you really beat that? Worth the $6K.
