Yamaha FB-01 Tone Module
This was theoretically sort of like 8 DX100s in a box, however it was temperamental and ended up pretty useless. The preset sounds could not be altered unless one had access to editing software. At one point I transferring some of my choicer DX100 sounds onto the FB-01 using a borrowed computer, but something was lost in the data transfer, and many of the sounds ended up sounding far less impressive. Buying the TX81Z later remedied the situation.
