Summary	07759: rampart, rampart2p, rampartj: Digitized sounds are heavily favored over synth
Description	In the arcade Rampart's digitized sounds (drums mostly) are loud but not overwhelming, whereas in MAME they heavily drown out the rest of the music. It is difficult to put numbers to this, but one could go by the SNES port for a better sense of how the sound should be.
Steps To Reproduce	Just play the game. Anyone with experience with the arcade version will notice it immediately.
Additional Information	This has always been true of MAME's rampart drivers.

Direct sound recording of the PCB is the most appropriate. We will accept arcade soundtrack but please keep it in mind that they usually have delay effected/echoed/remixed and don't always represent the real sound balance correctly. Without original recordings from authentic PCB outputs, we don't usually consider such reports as bugs. A console port cannot be used as a guide here. Do you have a confirmed recording from the arcade game that can be used for reference? I'd also suggest you check out the upcoming release from mamedev.org (0.225). A lot of work was done with audio streams to better handle multiple streams from different sources.

You should be able to do this separately. It is hard to get all the sound chips at the right default volume for every game which is why the volume mixer exists.

I don't have access to a physical Rampart machine so I cannot provide reference that way, but I do own a copy of Midway Arcade Treasures for Gamecube, which includes Rampart as a game. Would it be helpful if I recorded gameplay from that? It's kind of a copy of a copy though.

If I have to be the one to close this I can, otherwise I wouldn't be opposed to someone else doing it until such time I can find a Rampart machine in the wild (which is very unlikely for me).
