In simple terms, subtract 8 from the current value and set it to that new value.

Many thanks
To each his own, but that feature is one of the things that makes Loksound superior to some of the others and more prototypical. Of course, if you try to MU the Loksound with a different sound decoder that doesn't do that...

An easy way to find what a CV does using JMRI, go to the CV pane and change the CV in question and then chnage it back to the original value (it should now be highlighted in orange). Now look at all the other panes to see what items are highlighted in orange. All these items are affected by that CV.
Doing that with CV124 on a Loksound select shows several items on several panes changing. On the Advanced pane, there was a check box for startup delay.

Each CV is made up of 8 bits.
That's a binary digit, base 2. So while a number like 542 is 5 hundreds, 4 tens, and 2 ones, a binary number like 10110101 is 1 * 128, 0 * 64, 1 * 32, 1 * 16, 0 * 8, 1 * 4, 0 * 2, and 1 * 1. Bits are counted right to left, just like decimal numbers, but since computers start counting at 0, the right must place is the 0th bit. In the example 10110101, Bit 0 is 1, bit 1 is 0, bit 2 is 1, and bit 3 is 0. Bits 4 and 5 are 1, bit 6 is 0, and bit 7 is 1.
In decimal you have 1's, 10's, 100's, 1000's, etc. In Binary you have 1's, 2's, 4's, 8's, etc. Powers of 2 - 2^0 for the zero bit is 1. 2^1 for bit one is 2, 2^2 for bit 2 is 4, 2^3 for bit 3 is 8. So, if bit 3 is currently on (1) and you want to turn it off (0), subtract 8 from the current value in the CV. If bit 3 is currently 0 and you want to make it 1, add 8 to the current value of the CV. Adding or subtracting 8 will only alter bit 3, none of the others. You can use the Windows calculator and switch to the programmer view and it will do decimal to binary conversions for you can you can plug in various numbers and see this for yourself.
I have a Loksound decoder in a loco. I want to change performance to eliminate prime mover startup delay. The manual says "delete bit3 of CV 124." What does this mean? I use decoder pro and CV 124 is easy to find. By how much do I change the value in CV 124 or do I do something else?
