 Driving Technique

A new feature of the DigiDrive E soundfiles allows the power to drop to the next power level below if you decelerate by one speed step. Acceleration of one speed step allows the sound to return to the higher power. This works in any power band. Useful to switch between power levels simulating changing loads or driver throttle adjustments at speed.

At any time, and in any sound set, F6 will force the sounds to either hold idle or spool down to idle sounds. This affects only the sounds, actual speed is unaltered.

So, you can engage F6 before moving and the sounds will continue at idle even when the loco moves. Use this for light engine movements, where no extra power is required.

Or you can use F6 when already moving and the sounds will revert to idle for Coasting.

Releasing F6 in both cases allow the sound to go to the appropriate power level determined by the throttle position.

If you reduce speed gradually before stopping, the project will put the loco automatically into Coast mode at low speed, enabling a dignified halt without the engine sounds playing at full power. This is an automatic, low speed, alternative to manually controlled coasting using F6.
