Reverse order:
3: No, Jordan is playing a regular Stage edition, CV outs were not available at the time this series was produced. Certainly, the standard Phatty has Gate in, CV Filter and Pitch and CV Volume aka expression pedal inputs, so it’s a great recipient for CP-251 and Fogger output. Be sure to see all 9 in the Jordon Rudess series in addition to the KbdWizard on YouTube for many inspiring videos/demos.
2: Voyager won’t necessarily be too complex but it’s certainly more intimidating due to a: dozens of more knobs and b: an even more complex system of nested menus. Even long time owners sometimes get lost or have to ask “how do I…”.
1: Personally, I’d go for the Phatty option but I suppose I should ask if you are doing this mainly for home studio / hobbyist type use, or if you play live primarily. If the latter than the Voyager is for you and best (depending on the genre of music you play) along side a poly synth of some sort. If, on the other hand you are just starting out or have a home studio and just enjoy playing (like many of us), then I would recommend the LP + extras.
My experience with the Moog gear is that my first Moog product was a LP Tribute, then I bought a Midi MurF, then sent in my Phatty for v2.0 upgrade (not necessary for Stage editions) and CV Mod upgrades, then bought a Voyager Old School, FreqBox, Taurus Pedals, 101 LP Filter on and on… point is it’s an absolutely perfect first analog synth and despite some people saying “selling my LP to buy a Voyager”, many Voyager owners want LP’s. I won’t part with either.
I think the most important thing you need to ask yourself is what sort of sound you are after, whether you’ll be doing more ‘playing’ with a band than noodling aka getting sucked into the world of Analog synthesis like many of us.
To answer your #1 questions specifically: Phatty has:
- built in arpeggiator
- Overdrive on Filter
Voyager has:
- larger kbd w/Aftertouch
- additional OSC
- noise source within mixer (Phatty adds Noise as an alternate mod source to OSC.2)
- additional (and more capable) Modulation bus
- ability to switch 3rd OSC into low frequency LFO
- many more CV ins (and basic CV out unless VX-351 is added)
BUT the Phatty + extras is too long of a list to begin to write up, especially after adding an additional Fooger.
Hope this helps somewhat.
