No, it's for the 20x40 which seem to perform better with these locos. We will supply 26 / 27 / 33 chips with a suitable speaker on request, and as part of a pack with the enclosures.
-
Yes, the second loco I recorded was 33109 at the ELR (the first being 33019 at The Battlefield Line). You are right, the engine sounds quite different on 109.
Yes I do offer a reblow service. If you send me a Private Message I'll send you a list of all the sounds I do on v3.5 & v4 chips.

Stop press: I had the Deltic running round my pal's big O gauge roundy-roundy this afternoon and it sounded reeeeally nice. The drone at high speed is captured to perfection. The flow of sounds needs a few minor tweaks but it's nearly there.
-
There is every chance of that. I'll make some enquiries.

Sugar cube speakers are the only way to go with the 08, anything else will be too quiet (I know from bitter experience). Fit two of them in parallel in the nose, after cutting out the rectangle of black plastic behind the grille. Only this week I found (again by bitter experience) that the Zimo sugar cubes are much louder than the CT Electronic ones, despite them appearing to be identical (apart from the colour - the Zimo ones are black, CT's are transparent).

So far I've laid down some basic engine sounds (start, idle, stop) and all the 'auxiliary' sounds (two different sets of horns, door slams, compressor etc) and these are all working very well. Progress on the engine transition sounds has been more laboured than I expected as the techniques I normally use to make them smooth and seamless aren't working nearly as well in this case. Looking ahead, I've got to find out all the intricacies of the two engine set-up and model it accurately in sound terms. This one is going to take lot longer than normal...
I do agree with Peter though, I don't believe a 4mm Deltic can ever be made to sound like a real one. This 7mm one will though, but a lot of work is still to be done.

Very, very difficult, near impossible in fact in 4mm. Tiny speakers cannot reproduce deep bass and you cannot change that fundamental law of physics. It's a fear of mine that people will be disappointed with my Deltic sound in 4mm, unless I can work some real magic (which is highly unlikely). Even in 7mm my early experiments have shown it to be difficult, at least with the Heljan loco. One idea people might try is to completely gut a 4mm loco to make a 'mobile speaker enclosure', and push it around with a motorised coach behind. I'm thinking of trying an isobaric speaker enclosure as well. If I make any progress I will post here.

Thank you for that doctor quinn, I knew someone would know. I wonder if they sound the same when running on those different systems. I'll wager there are some differences. I was looking forward to hearing what the traction motor blowers sounded like and we didn't hear them, or indeed see them as the locos went past completely hidden by the unit. A real Doah! moment.
And yes, I knew someone would spot the Jean Jaques Burnel reference. Of the two Stranglers solo albums of the time (Burnel's Euroman Cometh and Cornwell's Nosferatu) I much prefer Nosferatu, it's one of my favourite albums of all time, with a very gothic theme running through it. 'Wrong way round' is excellent, just like being at the Victorian fairground with Ian Dury as the barker. The only track on Euroman that really stands out for me is 'Triumph'. Brum, brummm!
-
I suspected there would be differences. There are various pitfalls for using these or the Leyland engines as generic sounds for other DMU's (type of transmission, number of engines, number of cylinders, type of exhaust etc, all of which can have a bearing on what they sounded like). I'm planning to offer two or three fairly generic DMU chips to begin with and enhance the range with completely authentic sounds as time goes by. There are dozens of classes of DMU so I think this approach makes sense.

Yes Paul, the picture is from my iphone. In good daylight with a stationary subject the pictures are superb given the size of the lens, but not so good in more challenging conditions. Very handy to carry around with you. Superb HD video too! Best gadget I have ever bought.
I'm not aware of any models of the 127 but a handful of other DMU's used Rolls Royce engines as far as I know, including the 110's which Hornby make a model of. Not sure if they were exactly the same engines but...
The new recorder is a Roland R26, it's a superb piece of kit. Very flexible in terms of inputs, small & easy to carry about, touch-screen operation, great sound quality, built in speaker, batteries and memory card would probably be good for 24-36 hours of continuous recording, works on AA's if all else fails etc etc.

I am very happy indeed with the Deltic recordings this time around; they are nice and clean with very little in the way of 'running sounds', wind noise or rail joints. Interesting what you say about 002, thanks for letting me know.
With the demand for reblows being what it is now, development of new projects is taking two or three times longer than it used to so it could be a while before the 33 gets upgraded, or before the Deltic sounds are all edited.

I believe they are made by CT Electronik. I got mine from Digitrains (link below), I've told Charlie to get some in as well.

Jeff / Paul,
I have made a start on a table detailing my recommended speaker fit for each class of loco or unit. The aim is to have this on a website in the fullness of time. It will also be added to the 'helpsheet' for my range of chips. The helpsheet is here;

Paul,
The v4 31 has been out for ages but I don't have a model, hence no video yet. It's up to the usual standards of course.

Jeff,
You can buy new chips with my sounds on from DC Kits. I also offer a reblow service direct (ie not via DC Kits). I'll send you a full list but most of them can be seen here; http://www.youtube.com/user/legomanbiffo/videos
The sounds are available on Micro, standard or XL chips, so yes 7mm is not a problem.

I think the noise you're referring to comes from the spirax valves which purge moisture from the braking system. All of my diesel sound projects have that on a function key so you can turn it on or off as required (it fades in slowly, continues for as long as the function is on, and then fades out when you turn it off).
The horn when moving off is not automatic. The driver blows the horn when moving off to signal to anyone who may need to know, that the loco is starting to move (eg people working on the track, who should acknowledge by raising their arm). It's probably in the 'rule book'. It is not automatic on my sound projects, you blow the horn(s) if you choose to.

Jeff,
Years ago I bought a copy of Designing, Building & Testing Your Own Speaker System by David Weems and have referred to it regularly ever since. I've built more than one set of hi-fi speakers and experimented extensively (and successfully) with the designs you've outlined in 4mm and 7mm scale models.
In the case of the 50, I was attempting to build an infinite baffle design of a larger volume using two drive units in phase. I've since realised the mistake I made was electronic and not a speaker design issue at all; I had wired the speakers in series rather than in parallel as intended. Since I've corrected this error the volume is much louder and the fall off in bass is much less obvious.
My experiments have shown that increasing the cubic capacity of the enclosure makes a significant improvement to volume. Gains of 50% are not unusual. Using the body or underframe of the loco or unit as the enclosure is highly effective. The improvement in bass is measurable and audible but not quite as dramatic. My most effective gains in bass have come from large bass reflex designs with long reflex tubes, employed successfully in my 56 and HST. I'm beginning to wish I'd gone for this with the 50.

Good advice which I did indeed follow; I bought the 70-200 f2.8 and used it with the D60 for a while (an excellent combination, I guess because you're using the best part of the optics). I've since added the 50mm f1.4 which is a great lens and one I use 90% of the time. Thinking about adding a 35mm prime just now but can't decide between the f1.4 or f1.8. Don't tell the missus though :-)
