Sorry 'bout being late. I don't get on the internet during weekends...
1 a polyphonic synth. Offcourse you can build a multitimbral synth. But it's mainly the same as building a monophonic synth for every voice you want, and adding a little mixer at the end. (read: a lot of work.) The midi-cv convertor has to be able to be played in polyphonic way too, offcourse...
BUT you can start building a modular (what I'm doing), each module (each VCO, filter,...) gets it's own package, and when you want a sound, you 'patch' up the modules. So you've got alot of modules, with even more wires between them... This is easily expanded with more modules, and in a while you might be able to patch it up for 2 voices... The modules you get are mainly remakes of older popular synnth-parts, with improved stability. Or they're better...
But I'll say it again, it's NOT cheap!
Virtual analog synths are getting quite good lately. They offer alot of functionality... In an analog synth, you've got a certain number of modules, pre-patched in a way, with switches. The virtual analog can mix up these blocks (order of the alogorithms) or replace blocks without problems. The way a modular synth allows you, but without wires all over the place.
And it would cost about the double, to get an analog synth (modular) that can do what these digital bros can do. With a modular, you pay for each module...
Software synths... Don't like to play with them. I don't have a good soundcard, and don't like sitting at my computer to make music...
If you check out virtual analogs, I was thinking about buying a virus. But I bought
a VS1880 instead. The virus is definately worth checking out...
