Digitrainsound Tornado Multi-Drive Version 1.0 By Paul Chetter.
Thank you for choosing Digitrains; we try harder to provide you with the very best sound projects available.
Please spend a few moments to read these notes which have been produced so that you may obtain the maximum satisfaction from your new sound scheme.
The sounds should work perfectly when the decoder is fitted correctly. Individual locos may require some fine tuning that you can achieve with your DCC controller.
What is Multi-Drive?
This is a system developed by Paul Chetter as described in his articles in Hornby Magazine, Issues 39 to 41. The sound recordings were made from an operating locomotive for authenticity.
The sounds have been programmed in such a way that you, the user, may change the way that the sounds respond to your driving style or needs. This avoids the need for reprogramming and all the additional costs that would imply.
Operating Your ZIMO Sound Decoder.
As supplied, your new decoder will work in a ‘light engine’ configuration, but you will be able to switch between the available sounds using your DCC controller using the straightforward instructions below.
This project utilises Zimo’s unique ability to switch between the sounds of a heavy
train load or sounds of a light engine, or even, with a little more input from you, to a wheezy loco with a leaking seal . These are all fully configured within the project, waiting for you to make your choices. You can revert back at any time. This gives you three times the fun at no extra cost!
All the CVs have been optimised for the Bachmann Tornado, but should work equally well with the Hornby version, or even other 3 pacific locos. You may need to make adjustments to suit your individual model.
There are 20 Functions, most of which have an individual sound attached. Some will perform a physical function (like turning on the lamps, if fitted), and some will do both (depending on equipment installed). Please study the list below.
Some of the sounds have a finite length and will play from start to finish when selected. Other sounds will ‘loop’ until switched off, whilst others will vary in length, depending on how you operate the F keys on your DCC controller. I’ll leave you with the pleasure of finding out which is which.
In any of the driving sound sets, increasing the speed step by 1 will produce an acceleration sound for a few seconds. If you wish continuous acceleration, ease the throttle setting upwards rather than 0-128 in one jump!
Similarly, in each sound set, a reduction of 1 speed step will stop the exhaust beats and the loco will ‘coast’ (or drift) for a few seconds before resuming exhaust beats. Continuous drifting can be simulated by easing the throttle settings down, one step at a time.
All sounds may be modified (including changing or removing them) individually, and the volume levels of each one may also be varied to your own needs. For this, and much more information on your decoder’s outstanding abilities, please download the latest Decoder Manual from: www.zimo.at/web2010/
The Sound Sets
There are 2 sound sets loaded on your decoder.
Set 1 Light Engine. At very slow speeds, this set will simulate a very lightly stressed loco. This becomes more aggressive with acceleration, and as speed increases.
Set 2 Heavy Loaded. This is the one to use if you have a heavy train on the hook.
Special Zimo Function on F5.
As supplied it is possible to toggle between Set 1 and Set 2 (change from one to the other and back again) and this may be done even whilst the loco is moving, with no loss of sound. This is useful to vary the sound of the exhaust beats. But it really comes into its own when you run light loco up to a train, couple up and chug away with the heavy sounds.
All you need to do to make this happen is to press F5 on your DCC controller, and press again to change back.
