Modular synths are incredibly flexible, but convenient? Not so much -- switching sounds frequently means wiring up patch cords, and that makes it harder to use for live gigs and other on-the-fly uses. Erica Synths has a straightforward solution to that: put everything on a card. Its upcoming Pico System III uses "voice cards" with preset patches -- you just plug in and go. There are five pre-configured cards in the box, but you'll also get five DIY cards if you're handy with a soldering iron.
