If you thought you had seen it all, think again. Doing what the eccentric synth-builder does best, Teenage Engineering have come up with yet another awesomely unconventional range of gear. Meet Hatshepsut: one of eight CH-8 Series choir dolls who's happy to serenade you in a mezzo-soprano voice. Features of the Teenage Engineering CH-8 They may make up the Teenage Engineering Choir but that doesn't mean the CH-8 dolls are easy to classify. They're perhaps best described as mini-synths that reproduce human vocals via a built-in speaker. Made of wood, each battery-powered doll can perform any music it's fed but can also be controlled via MIDI, sing solo or be teamed up with other members from the CH-8 line-up via Bluetooth-MIDI.
