” The FB-01 is simply an inexpensive, 8 part multitimbral digital FM synth module. It’s a 4-operator synth similar to the DX9 or DX100. You will need an external MIDI system exclusive editor to edit the patches. This can be accomplished by a dedicated editor program like Unisyn, or by creating SysEx control messages within your sequencing program. The FB-01 has a lot of organ, piano, brass, bass, guitar, percussion, and lead sounds. Basically this is a good source of typical FM-sounds.
Notes – this is 120V model.
It’s not in great condition so I am selling it for spares or repairs only.
The transformer is a little noisy, but this does not effect the sound. It seems to run a little hot, but I have had it on for hours with no problems with my step down converter.
If you want to strip it down it contains these rare chips – YM2164 4 operator IC, YM3012 DA converter and 2x D4464C-15L RAM.” Click here to visit listing on eBay
