A pocket-sized virtual analogue monophonic synth that sports eight knobs and 16 slide switches. The instrument can be bought complete or as a hackable board.
It may be digital, but the MeeBlip can sound gritty enough and shouldn't be taken lightly. What's more, it's open source, meaning that you're free to modify the hardware to suit your own ends. Oh, and unlike some other synths of this ilk, it has a MIDI Input on it.
Value for money:
The MeeBlip is certainly affordable - the downside is that, at the time of writing, it's also unavailable. Look out for a new version soon.
Other than its current unavailability, the lack of a proper analogue engine might put some off, but you should ask yourself how important this really is on an instrument of this type.
Experimenters and anyone who wants an affordable and tweakable hardware synth that they can plug a controller keyboard into.
