Ok.. Then I understand. So actually this precision is what costs, in the MAME FM OPL emulation, you can reduce the quality of the audiogeneration, something which is generally done for lowend devices, i.e number of bits used for envelopes etc, to get "good enough" sound, whilst still getting a performance which is acceptable.i

I think adding such configuration option to the DosBox implementation is something that should be done, specially if it is planned to get rid of the mame impl. in the longrun.
