I have a MidiVox SynchroVoice for sale, including the neckband, standard 3-prong power cable, and 2 midi cables. Please note that the fabric covering for the neckband disintegrated, so the biosensors are bare. I hooked it all up to my Roland synth and with the neckband pressed to my larynx, I was able to produce sounds by using my voice. I have no interest in taking this further and would like to sell it to a more interested user. The original price was $1,295 US dollars. I have seen an untested one without the biosensor neckband for $400. Please make an offer. firstname.lastname@example.org Thank you.
