Dec-27-01, 10:59 PM (EST) "Brake Sounds - Troubleshooting - any suggestions??" I know the answer is out there! I installed a high nose Geep 9 and cabview by Svante. The Eng file references the GP38Eng and Cab sounds. Here's the problem: When releasing the trainbrake in the MSTS version of the GP38 you get a hiss and then a "pop" at the end. When releasing the brake in the GP9 you get a hiss and then about six or seven "pop" sounds. They use the same sms file (as far as I can figure out). Can anyone suggest where the problem might be? All the sounds "que up" it seems.Thanks gang.Mark

Dec-27-01, 11:46 PM (EST) 1. "RE: Brake Sounds - Troubleshooting - any suggestions??" Its probably in the ENG files in brakes section.... compare them... especially the parts concerning the compressor.... One of them is taking longer to "recharge" the air flasks....------Chuck Schneider---------

Dec-28-01, 12:48 PM (EST) 2. "RE: Brake Sounds - Troubleshooting - any suggestions??" Troubleshooting issues like this would really be aided by some documentation on what exact events the various Discrete_Trigger values refer to. As no docs exist, and non are likely to be officially issued then maybe we here in this forum should start pooling our knowledge (in a structured manner). Any takers?Stuart Remove | Alert Edit | Reply | Reply With Quote | Top

Dec-28-01, 03:37 PM (EST) 3. "RE: Brake Sounds - Troubleshooting - any suggestions??" Thanks Chuck! I compared the files and they are vastly different. I haven't had time to go line by line on the code related to Brakes, but on a hunch I swapped the stock GP38 ENG file with the new improved physics package by Scott Borchardt. Scotts ENG file also gives me the sound problem. If we knew more about triggers (as Stuart suggests in his response (thanks Stuart) and simultaneous playing of the sounds, I could probably fix this the "right" way. As is, I'll experiment with particular attention to your suggestion, until I find a value that works..........or delete the offending .wav and associated references (if I can!). Thanks for pointing me in the right direction.Mark

Dec-29-01, 11:40 AM (EST) 4. "RE: Brake Sounds - Troubleshooting - any suggestions??" LAST EDITED ON Dec-29-01 AT 11:41 AM (EST)See if MaxReleaseRate ( ) in your .eng file is set to 2.27 (I think it is on most files using Scott's physics). Try changing it to 10. that eliminated the endless string of pops and hisses while the pressure bled down for me.And Amen to pooling resources on the sound files! Some of the triggers are truly baffling.krswen Remove | Alert Edit | Reply | Reply With Quote | Top

Dec-30-01, 10:51 AM (EST) 5. "RE: Brake Sounds - Troubleshooting - any suggestions??" Thanks a million - it worked! Now begins the quest to figure out why and how. I'm also working on the dynamic brake control to get one click when going to "setup" and one click when turning it off. Then eliminating all of the other dynamic brake clicks. I think I'll have to go from a discreet to a variable trigger - not sure yet. Thanks for the help.Printing out these files and study of their structure is beginning to shed some light.Mark

Dec-31-01, 12:37 PM (EST) 6. "RE: Brake Sounds - Troubleshooting - any suggestions??" Go into your *cab.sms file. Scroll down a fair distance until you find this block:Stream (
Skip ( **** This stream plays all the controls samples **** )
Priority ( 5 )
Triggers ( 9
Discrete_Trigger ( 15 PlayOneShot ( 1 File ( "gp_reverserf.wav" -1 ) SelectionMethod ( SequentialSelection ) ) )
Discrete_Trigger ( 16 PlayOneShot ( 1 File ( "gp_throttlef.wav" -1 ) SelectionMethod ( SequentialSelection ) ) )
Discrete_Trigger ( 17 PlayOneShot ( 1 File ( "gp_abrakef.wav" -1 ) SelectionMethod ( SequentialSelection ) ) )

Discrete_Trigger ( 18 PlayOneShot ( 1 File ( "gp_ibrakef.wav" -1 ) SelectionMethod ( SequentialSelection ) ) )
Discrete_Trigger ( 20 PlayOneShot ( 1 File ( "gp_dbrakef.wav" -1 ) SelectionMethod ( SequentialSelection ) ) )
Discrete_Trigger ( 26 PlayOneShot ( 1 File ( "gp_sandf.wav" -1 ) SelectionMethod ( SequentialSelection ) ) )
Discrete_Trigger ( 37 PlayOneShot ( 1 File ( "gp_flightsf.wav" -1 ) SelectionMethod ( SequentialSelection ) ) )
Discrete_Trigger ( 48 PlayOneShot ( 1 File ( "gp_econtrol1.wav" -1 ) SelectionMethod ( SequentialSelection ) ) )

Discrete_Trigger ( 51 PlayOneShot ( 1 File ( "gp_ebrake.wav" -1 ) SelectionMethod ( SequentialSelection ) ) )
)
)
You can do one of two things .... see the line: Discreet_Trigger ( 20 ....dbrakef ....?Either delete it completely, or type Skip( in front of it and put another ) behind it. Works the same as a Comment line in the .eng file. Don't forget the trailing ) if you "Skip" it. Also, go up to the top of the block and change Triggers ( 9 to Triggers ( 8.As always, back up your file before you start fiddling, just in case ..... krswen Remove | Alert Edit | Reply | Reply With Quote | Top
