One for the programming experts probably. Is there any way of linking the 'chuff volume' within the sound files to the the steam chest pressure. eg when the steam chest pressure is greature than 75% boiler pressure you get full sound volume, at 50 % half volume and when throttle is shut, ie. coasting, only train sound and normal loco background sound files. Perhaps this would need complementary sets of power wave files at the appropriate chest pressure levels. I might make it sound simple but am too much of a dinasour appreciate what it might involve.
Have you taken a look at the generic 2cyl and 3cyl sounds on uktrainsim.com ? I can highly recommend them, but you need to register (free) and then download very soon after 8pm GMT before the available d'load bandwidth is used up. (or pay a subscription)Cheers, Nick.
I understand what your asking and no it's not really possible with the current code. More realistic steam sounds will require several fixes in the code and will be fairly complex. The code will need to be capable of triggering a set number of chuff samples per revolution of the wheels, 4 per revolution for standard engines, 6 per for 3 cylinder locomotives and so on with support for geared locomotives as well as compounds. Volume could be linked in some way to steam chest pressure but samples would need to be selected by both rpm's and the valve cutoff setting. Hopefully the code will be improved and more flexable for future versions, we'll see.
