Hey :) I have the Spiderwave OPL4 card, but playing MOD or S3M files on my turboR GT using the MOONMODT util is giving annoying crackling sounds. The original Moonsound card doesnt have that issue. Then again, other utils using spiderwave opl4 such as NOP MOD PLAYER, SYMBOS MOD PLAYER or even MBWAVE don't give issues... Is this a known issue? Thanks for responding :) Edit: Roboplay also gives crackling noises when using Spiderwave card...The original Moonsound card doesn't have this issue using Roboplay.
This card was tested on Sony HB-F1XD, Panasonic FS-A1,uMSX and Omega. I don't have TurboR so I can't make a test. Can you test on a non TurboR machine?
