It's obvious you've never owned either. The FB-01 sounds like a kiddie toy compared to a real DX.
yes i have owned an FB-01... but i got rid of it because the buttons to interact with it were damaged.
fb-01 can do some wickid basslines.. you would be surprised what some people can get out of that crappy 4 op module
but, i dont think that FM-7 is a real replacement for a DX7 or DX100...
theres many other FM synths now aswell with the newer version of reason you can get an FM synth "Rack extension"
none of them sound exactly like A DX7.
my comment was because mactron had like 5-6 instances of FM-7..
i was thinking why spend all your cpu on live instances of fm-7.. when u could render this to wave.. or use external gear to be able to "do more"
u only have so much cpu power.. and can only run so many instances of "virtual synths" - remember they are "Virtual" as in "not the real thing"
i just received in the mail 6 new voice chips to restore my juno 106.. im taking it to a tech (who used to work for roland canada) to install them for me.. cant wait to hear the juno106 after
its been restored + calibrated!
