Question: I like a warm, dry sound like Roland Juno 60 but the vintage Juno are not multitimbral. Is there a modern synthesizer, perhaps digital but preferably analogue, that has the warm sound of Roland Juno 60 and also is multitimbral? I used to own a Roland Juno 60 and play it with the DCB converter but I gave it away to a friend and now I want another synthesizer. 

Update
------

I've gotten a Roland Juno 106 for SEK 5500 (abt 820 USD) and I'm happy with it even though it's not multitimbral.

Answer: 
Check out programs like Nanoloop or LSDJ on a Gameboy or emulator to get a feel for how the limits of the chip shape the way people write for it. You have amplitude and filter envelopes ranging from instant to a few seconds. I believe the hardware enables pitch bending as well if the software supports it.

For me personally the biggest feature of the "NES sound" -- other than the filtered square wave -- is the use of rapid arpeggiators to get around the limited polyphony. On the Gameboy, the noise channel is monophonic, one synth channel can do chords (of up to 4 notes) and the remaining two channels are monophonic but arpeggiated. 

If, for example, you replace a quarter-note chord with sixteen 64th notes arpeggiated over the same 3 or 4 notes, I bet that will already start to sound "videogamey" to your ears.
Hey! I don't know much about how the early consoles worked. But if you're interested, here's a VST plugin you could have a look at. It's called the Magical 8-Bit plugin. It might give you an idea or two somewhere. You could also hook this up to a midi controller, I'm sure?

I downloaded this a while ago, but since then the site has changed to japanese. Here is the link -> <http://www.ymck.net/magical8bitplug/index.html>. If you use Google Chrome, it will translate the page for you.
