Dapol Class 08 - Paul Chetter and Sound/Zimo - Questions?

Recommended Posts

Well today I fitted the Zimo chip with Paul's sound file and the twin speaker as shown above. A couple of observations. When activating either of the horns there is what I can best describe as an almost percussive quality at the very start of the 'toot'. I don't know if this is the sound file or the speaker. Also, when running with flange squeal, when I turn it off, immediately prior to to it stopping the sound almost sounds like a micro-second of radio chatter. That is the best way I can describe it. Has anyone else had similar observations?

Further to my previous post, I found that turning the master volume down from the default (which I think is 64) down to 20, made a big difference, and is plenty loud enough. I'm not able to run this loco in at the moment, in fact I have about 18" of track! At present, with clean track and wheels, it is starting to move at speed step 8 with my Powercab, after I altered the start voltage to 4. Hopefully, when it is run in, I can reduce that.  Any observations welcome.

 

PS It sounds lovely!

I discovered and highlighted a couple of issues for which I have to return my chips for a reblow.

 

flange squeal and buffer clash is meant to be speed related, but wasn’t.

they have updated their files, but the only way to rectify the problem is to reblow it. Unfortunately I am in Australia, so my 09 will be out of service for nearly a month

I can now get it to run from speed step one up to speed step 10. However, as soon as I hit speed step 11, it stops and won't start again until the mid 20s speed step. This is wherever it may be on the track, with track and wheels clean, so not related to those factors. Very weird.

Update on the 'dead spot'. A reset of CV8 to 8, cured it. Have sent it back for a reblow though ref. the buffer clank and wheel squeal 'glitch'. Also ordered a second decoder for my other 08

Received my re-blown Zimo chip with the updated Paul Chetter file, from Digitrains. Now all working well. I ordered a second decoder with the same ) sound file uploaded. They arrived with an updated instruction sheet. The flange squeal is much better. A question however, for anyone in the know. For my second installation, I want to change the default air whistle to the later fitted air horn. The accompanying notes indicate that the appropriate CVs are 519 and 522, which correspond to F3 & F4 respectively (single toot and double toot). I can't find anywhere in these notes what the new value should be for each of these CVs. Neither can I find information in the decoder manual. Can anyone enlighten me please?

I suggest a quick call to Digitrains

That was going to be my next port of call Ian, if no-one turned up trumps here. I can't even find CVs 519 & 522 listed anywhere!

You might do better in the DCC Sound section.

The stuff you are asking is not sale specific

Steve,

Here's an extract of my Class 08 User Notes about changing to alternative sounds:

 

Alternative Sounds

 

To add to your long term enjoyment of this sound project, there are a number of alternative sounds included on your ProtoDrive equipped decoder which are not assigned by default to any F key. (There are only 29 keys available).

 

The default sounds are shown in the Functions List below.

 

This is how to use the alternative sounds. In Functions List Sound ID column, find the CV corresponding to the F key you wish to use. Put the ID of the sound you require as the value of that CV.

 

e.g. to change the default Wooden Doors (ID 28) sound to Metal Doors (ID 23), make CV564 = 23, and vice versa to change back again.

 

 

Default                                                                         Alternative

 

Whistle, ID 18                                                                  Air Horn Toot, ID 17

Whistle Toot Toot, ID 19                                                Air Horn Acknowledgement, ID 16                     

Wooden Cab Doors, ID 27                                             Metal Cab Doors, ID 22
Air Release 1, ID 42                                                         Air release 2, ID 20

 

 

You may need to adjust the volume of the replacement sound, use the appropriate CV shown in the Functions List.

 

 

If you get mixed up, don’t panic. CV8 = 8 reset will restore all defaults (including loco address) but will preserve all sounds.

 

So, to change the default Whistle on F3 to Air Horn Toot, change CV519 (always used to change the sound assigned to F3) from default 18 to 17.

 

Similarly, for F4 use CV522 and the respective value from the list above. (Use the ID number, digits only).

 

A note of caution, however. If the sound project has been amended since these notes were prepared (eg speed related flange squeal added) the sound IDs might also be changed. i.e. the IDs may be out of date.

 

If the above does not get the correct sounds, come back to me and I'll investigate further.

 

Best regards,

 

Paul

Thank you Paul.  The user notes I have are V18.12 and the info you provided above does correspond with the notes I have. What was confusing me was the term 'ID', as I wasn't sure if that was referring to the CV value or something else. May be worth considering  using 'CV value' in brackets after 'ID' for idiots like me!  :-) . I do have the most up to date sound file as it was supplied by Digitrains only a couple of weeks ago and does have the speed related flange squeal.

 

Have just had a play with the two CVs concerned (519 & 522).

Entering a value of 17 into CV519 results, not in an audible warning device but, what I can best describe as a slightly more aggressive brake squeal. Rather like it's making an emergency stop!

Entering a value of 16 into CV522 again, results not in an audible warning device, but a sound which is a bit like someone shouting 'Oy!'

 

It would seem, therefore, that the latest iteration of the sound file has effected changes to the values of those two CVs.

 

Regards

 

Steve

OK, it should be CV519 = 15 and CV 522 = 16, in your version.

 

The acknowledgement horn (value 16) is a very short toot. There are no recordings of anyone shouting 'Oy' on this decoder.

That's excellent, thank you Paul.  I'm presuming that once CV 519 is changed to 15, although CV522 is still changed to 16 (as before), its effect is simply to repeat the altered sound of CV519? 

I rather liked the idea of someone shouting 'Oy',  it would be reminiscent of 'bunking' sheds in the 60s!   :-)

 

UPDATE: Changed CV519 to 15 and that has changed the whistle to horn. However, Changing CV 522 to a value of 16 is still giving me a single 'toot' rather than a double one..

Then press the horn twice. I have to at work if I want 2 toots

This would seem to be the case Ian. If I am understanding things correctly, when changing the F4 value (CV522) from Whistle (value 19) to Air Horn (value 16), the practical result is that instead of continuing to get a 'double-toot', albeit with a horn rather than a whistle, it changes to a short 'single-toot' Air Horn Acknowledgment. I was under the, clearly wrong, assumption, that the 'double-toot' facility remained constant with F4, irrespective of which of the two values were entered

I shall know all these damn CVs off by heart before long :-)
