PK-5A vs Taurus
By the time you buy a dedicated module for the bass sounds you've probably spent at least 1/2 the cost of a set of Taurus III's and they will never sound the same , and most likely not as good. Then there is the matter of resale value These have very little and the Moog's will sell for close to what you paid for them after the 1000 they made are all bought up if you keep them in good condition. Add a midi board and you've got yourself a basic real analog synth, then if you add a few Moogerfogger stomp boxes and it could be quite special. They PK's just seem to be priced too high for what they do, which as far as I am concerned isn't very much. Moog pedals can also be used as midi controllers and if most of the buttons etc. are assignable, they will actually have more midi controllability than the PK's. I suppose that it's just that I desperately want a set of Taurus Pedals, but then Roland had to come out with the Jupiter 80 and I can't, unfortunately, afford both. Guess I'll have to use a real Bassist if/when I play out of my home studio. They are nice MIDI pedals. But controllers is all they are, and they aren't exactly inexpensive. There are also organ style MIDI pedals with more octaves etc. I will say, that if you are thinking of getting pedals, and you have never heard or played the Moogs, you should do so. Nothing sounds quite like them when played through a proper sound system, one that can move LOTS of air and recreate waves right down to 20Hz and below (harmonics) Sub 20hz waves FEEL like a large door shutting in a small sealed room. Large correctly made horn subs with long excursion woofers driven by several thousand watts would do nicely for a demonstration. That's how I heard them and they left an indelible impression. Just my own opinions, nothing else. Be happy about whatever decision you make! Peace.
