== LokSound Multifunction Decoders==
----
=== LokSound 5 Series ===
 The LokSound 5 is designed with the European market in mind. Momentum multiplier (CV 3 and 4) is 0.25. European modellers are more likely to be using some form of automation, requiring much more exact stopping distances or times. The LokSound 5 Multiprotocol does not support .
 The LokSound 5 DCC is designed for the North American and Australian markets. It supports CV6 (three-point speed table) with a multiplier of 0.896 for as per the NMRA Standard.
The LokSound 5 at 30 x 15.5mm will fit most HO and OO scale locomotives.
The LokSound V5 multifunction sound decoder has the following features:
# DCC with , 
Multiprotocol Modes Available: 
# M4, 
# and 
# 
It supports in DCC 14 and 28/128 speed steps, with 2- and 4-digit addresses and up to 32 functions available.
=== Additional Features ===
==== Automation ====
# Zimo braking system
# Lenz system
# Braking with DCC brake generators or possible
==== Sound ====
* Up to 10 channels simultaneously. 
** 16 Bit / 31250 kHz samples
* 3W output power 
** Speaker impedance: 4 – 32 Ohms. 
* 128 MBit of memory for sound samples 
* Volume of individual sound fragments adjusted separately. 
* Three separately adjustable braking functions and two alternative load scenarios
==== Functions ====
Depending on the interface every LokSound 5 has at least 10 amplified outputs
* or interfaces have an additional 4 outputs for controlling servos or as logic outputs. 
* Brightness of each lighting output can be adjusted separately.
* Coupler Waltz - Easier uncoupling
==== Motor Control Features ====
* Variable 
** 10 kHz to 50 kHz 
* Silent operation, particularly for coreless motors.
* Load control: 10 separate CVs
* : automatic calibration of the decoder to perfectly match the motor. 
* 1.5A rated motor current
=== LokSound 5 DCC ===
* North American/Australian market DCC only multifunction decoder. All the features of the LokSound 5 without multi-protocol support
* CV 6 and a three-point speed table (Not supported in the LokSound 5 Multi-protocol)
* RailCom Plus
* 14 functions are available
* Current Output: 1.5A
* Analog DC operation
 LokSound V5 DCC multifunction decoders are exclusive to the North American and Australian markets. Momentum CVs 3 and 4 have a multiplier of 0.896, conforming to NMRA S9.2.2.

Large scale (0) multifunction decoder: 51 mm x 25.5 mm
* RailComPlus
* 3A
* 17 function outputs
* Two RC servos supported
* Dual power amplifier can drive two speakers
* Integrated PowerPack, 
* Pin headers and a matching adapter board
* 51mm x 25.5mm
Suitable for applications where an XL will not fit, or isn't required.
=== LokSound 5 XL===
Large gauge: G and 1
* 55 mm x 41 mm
* 4A 
* 19 outputs 
* 4 RC servos supported
* Integrated PowerPack
* Screw terminals
* Pin headers for Gauge 1 installations
=== Essential Sound Unit ===
 OEM Only. This product is not available for retail sale.
This is a cost reduced multifunction decoder running modified V5.0 firmware. It features very limited programming capability as per the locomotive's manufacturer's specifications. Many CVs cannot be altered, and the firmware cannot be changed.
It is not possible to load new sound projects, as these are locked. If a new sound project is desired, the decoder must be replaced with one that allows loading sound projects.
=== LokSound Select ===
*; V4.0 multifunction decoders have been discontinued.
=== LokSound V4.0 ===
==== LokSound Full Throttle Diesel Features ====
* Drive Hold
* Run 8
* Coast
* Brake
* Dynamic Brake
== LokSound Multifunction Decoder Programming Notes ==
----
=== JMRI ===
Certain issues with JMRI's code can result in problems with LokSound multifunction decoders.
# Memory installed in the computer: Less memory available results in slower read speeds. Installing additional memory (if possible) improves this and other functions of the computer too.
## The same is true for the Raspberry PI computer. Older models with less memory may experience issues.
# Digitrax: The PR4 is much faster than a PR3 when reading the contents of a LokSound multifunction decoder. 
==== Identification of the LokSound Multifunction Decoder ====
 Use New Loco → Read Type from Decoder to determine which decoder is installed. (JMRI V4.19.5 or higher versions.) 
==== First Steps ====
 JMRI can require a lot of time to read all the CVs used in an ESU Multifunction Decoder.
# Read Full Sheet instead of Read All Sheets. This method reduces the likelihood of causing errors when reading a decoder with a lot of CVs. 
## Upon completion, some CV values may be missing, which are displayed in red. 
## Repeat Read Changes on Sheet as needed, until no CV values in red remain. 
### Click on the Status column in the CV pane until a down arrow (↓) appears. Red items will then be displayed at the top of the column. 
# After making changes on a programming sheet, Do Not Use Write/Read Changes on the sheet. Switch to the CV pane, use Write/Read changes on that sheet.
=== Decoder Reset ===
 
 Do not attempt to reset a LokSound decoder using Operations Mode. 
LokProgrammer:
* Programmer Menu
** Reset Decoder
DecoderPro:
* Select the desired roster entry in Program Track mode
** Click on Resets menu
*** Click on Factory Reset
== Sound Files ==
LokSound V4.0 sound files can be loaded into a V5.0 multifunction decoder, but there is no conversion of the bit rate.
LokSound Select sound projects are unique to the Select, and cannot be loaded onto other decoders, and the reverse (V4.0 and V5.0 files) is also true. Select sound projects are only compatible with the Select decoders.RDC-1 with ESU Select decoder - Best Sound File To Use?

==== OEM Notes ====
===== Rapido RS-18 DCC issues =====
Owners of the ALCO RS-18 (Video) by Rapido Trains have reported various issues with operation of the DCC equipped locomotives.
These models have the LokSound V5.0 multifunction decoder. Rapido has published the following fixes for these issues:
* CV51 = 20
* CV52 = 5
* CV54 = 25
These changes will be lost if a factory reset is performed. A LokProgrammer can update the firmware so these values become the default.
These changes are unverified.
For reference, LokSound Manual at Rapido website.
