ensoniq doc voice chip

i have plenty of spare doc synth chips

and was wondering in interfacing this chip with midibox as hardware control of it and making a 4 osc 16 voice synth or a 16 voice drum machine using 8 bit samples

any one want to colaborate on ideas and possible interface for the e sync thats provided by the 8bit cpu motorola 6809
