The OPL4 routines don't currently work on MSX turboR machines in R800/"turbo" mode, because the wait times are too short.
Look at msd's answer and the opl4_out_wave routine in this forum thread

After the changes done for the MSX.org Pimp My PSG challenge (pimpypsg branch), I cannot reproduce the problem. The player seems to work without dropping notes even in R800/turbo mode, tested on a real turbo R ST machine and original MoonSound.
Maybe the fix was to change some routines from "out/wait/out/wait" to "wait/out/wait/out" style.
