Two different horns

[soo]

All,
First, the MKT SD40-2 from IMRC has two horns mounted. A multiple chime up front and a lone single chime on the long hood behind the radiator fan.
So here's the ?, can there be two horn sounds?. I know func2 is the horn, can there be a different sound for a horn on another function number?
Considering that different functions control different sounds..brakes..air spit ..prime mover. Why couldn't you program a function with the single chime horn??
Am I crazy to think this..if this could work...it would be cool.
If it helps..I have a Lok Programner( awesome Christmas gift) to use. It's sitting in it's box screaming " use me "
Thanks for any help

I'm 99.9% (99.8?) sure it can be done but John C. or Rick B. could probably explain how quicker and better than I (I would have to do some research).

I believe it's a matter of assigning sound slots and remapping functions. You may have to give up a sound effect somewhere, but perhaps not.

Wyatt, I am shutting down for the night, but I will look at the sound project in the morning and let you know. It will depend on whether or not there is an alternate horn in its own sound slot. Some projects have one, others don’t.

OK - I just looked through all EMD 645E3 sound projects for Select decoders (there are quite a few, not just the file made for IMRC) and, unfortunately, none of them have a separate horn in another sound slot.  While this would be very easy to do in a full V4.0 decoder (custom sound files), only ESU can make Select sound projects. 

The horn, in Sound Slot 2, is controlled by the horn selector bits in CV48.   There are potentially 16 distinct horns available in any given sound project. But one cannot switch between them "on the fly" (would be a neat feature). Some projects do have alternate horns (usually electronic sounding ones, or special grade crossing sequences).  Most projects have a number of alternate bells

If a Select sound project did have an alternate horn, programming it to be the horn for reverse direction would be simple.   In the Function Mapping tab (of either LokProgrammer or DecoderPro), there is a row which shows "F2" under the "Conditions" column; and either the name of the primary horn (in LP) or "sound slot 2" (in DP) under "Sounds" column.  What you would do is change the value in the "Conditions" column for this row to show "Forward, F2".    Then, at the bottom of the function map, you would add a new row (the order of the rows in the map doesn't matter), with "Conditions" = "Reverse, F2".   Then, under "Sounds", select the alternate horn sound slot.

Rick,
     Thank you for your time,, well it was worth a shot. I appreciate the quickness that you researched my question. As I sit here now I am fixing to put two of the Lok Sound OEM chips in two -2's,, one Soo and one MKT. I am using the 8x12 soberton with the enclosures from keystone customs on the shapeways site.

Once again thank you for your time.
Y-It

OOH!  If you are adding a board, you might want to consider hard wiring a V4.0 Micro, rather than using the Select 73199 board.  Then you could do what you want.
