I suggest a used Rhodes for Electric piano. A suitcase could get you the amp. You could use the effects loop for sounds. You could introduce another synth into that amp or another amp, one of the channel inputs on the side of the amp. This would be more economical than a Nord Lead II but they have great emulation of the Hammond and EP sounds. If you went the Nord Lead route, you could then use its midi and then just put a DSI Tetr4 on it. The only limitation to this scenario is you said you want the knobs to twiddle. A DSI prophet 08 would be great for that aspect of it. But true, you won’t get EP sounds from it.
About Wendy. Secrets of Synthesis came out in '87. Think about that. This is an analog synth pioneer (Player, not designer) who, in 1987 is saying that Digital is better than Analog. So if you are saying a Virus is better than a Prophet 08 and you’re using Wendy’s quote from 1987 to support that statement, you need to realize that Wendy never knew what a Virus was going to be. In 1987 everyone was ditching their Minimoogs–they were available in pawn shops for a couple of hundred bucks! Something relatively new at the time was the Oberheim Matrix synths, though, and the Xpander and Matrix 12 were monster analog synths, not incredibly easy to program, but still there were many routings–much more than the baby brothers Matrix 1000 and the Matrix 6–and the pads you could produce on these (Xpander and Matrix 12) are incredible, because of the extra stuff they had. Various ramp waves and lag processors and other stuff you could apply to the filters, of which there were several notch filters and bandpass filters that you could add resonance to, and get all kinds of complex and interesting pads on.
I know people who were into synthesis when it was actually new–like Wendy–and have heard them make similar statements. These people had long sold off their Oberheim SEM modules, but they still had their Xpander. They had sold off their ARP Oddysey but still had their ARP 2600.
Wendy was an innovator, and in 1987 Digital synthesis (particularly FM synthesis like the DX-7s and, later, the then-newer SY line of the early 90s. I read an interview with Wendy about the SY-77 and she was raving about them. She spoke about their ability to create various microtonal scales, etc. And it is true that FM synthesis was a very wide-open platform, and you could come up with many different tonalities because of their complex modulations that happened with the various algorithms.
But this was before VA. I think every time I hear VA it sounds cheap. It may be valid for most dance/stage applications, because by the time the sound source is amplified and put over a high-wattage speaker system, and mixed in with other sound sources, the human ear can’t generally detect the difference. Still, if you listen to analog oscillators and filters and compare them over headphones or a good speaker system, by themselves without processors added, VA comes up very much short in emulating analog sounds. That doesn’t mean they’re not valid.
So for the above reasons I am going to simply remove VA synths from my personal list of choices. What does that leave left over? It leaves very few analog synths, the P08 and Tetra and other DSI being part of those choices. I’m not shopping so I’m not aware of very many other polysynths being sold today. The Andromeda is no longer sold. It has good word out on its sound quality and it probably has fantastic patches. I am not aware personally of how good the pads are on the Prophet 08. I would guess though that you could get the best of both worlds with a Poly Evolver. Those feature 2 analog and 2 VA oscillators per voice. You could get P08 sounds and Virus sounds out of it, and combinations of the 2 so I would imagine you could get all kinds of thick pads from a Poly Evolver. That’s just based on limited viewing of them online, though. I have personal experience with the Xpander and Matrix 12. If you could find a good keyboard/Midi controller you could have your cake and eat it too, by getting a controller synth like the Prophet 08 or a Poly Evolver, and then if you feel like you need some EP emulators you could get a Nord Electro Rack. Or, go the other way around and get a Nord Electro and use it to control a poly synth module like an Xpander, or a Tetr4. There are several ways to approach it, I think the onboard knob outlay of a Poly Evolver or Prophet 08 is very enticing, and then you could get a nord rack later. I don’t see the benefit of getting more than one keyboard controller unless you need them for discreet control of the sounds and the ability to play other sounds with another keyboard. The extra money in cost seems redundant.
Also I don’t mean to offend anyone who’s hell-bent on getting a good VA. You can get them from your computer as well, though. I just think that MIDI is a good thing to use to save space, and so far my ears haven’t been convinced that VA is really better than or as good as analog. It may be great at what it does, though, without being compared to analog.
