The Ondes Martenot

This is an oldschool version of an instrument I just discovered for sale at Noisebug


From their website:
The Persephone is a fingerboard analogue synthesizer with CV and MIDI in and out. At the first sight, the Persephone reminds of the first electronic fingerboard instruments developed in the 1920s. But beyond this vintage look, the Persephone allies sensors technology and digital controls to a pure analogue generation of sound. The Persephone musicality will be determined by the way it is played. The Persephone respects the traditional play of the first non-keyboard electronic instruments with the right hand controlling the pitch and the left hand controlling the velocity. The ribbon zone can allow all kinds of play. When scaled, the Persephone can be played like a regular keyboard. Though there are no fixed preset notes with the ribbon, keyboard players will easily find their way. Guitars and bass players will certainly play it like a chord instrument and get sounds that are closed to cello or violin, especially when using vibratos. Jazz players will enjoy slapping the Persephone's ribbon to get wonderful sonorities.

So many instruments, so little cash.
