The Soundtraxx Tsunamis' chuff rate  can indeed be adjusted via the CV's without the need for an axle cam but I find it isn't easy to set the chuff rate correctly at all speeds.

If you set the correct 4 chuffs per rev at very slow speed it is way out at, say, a scale 25 mph. Conversely, if set correctly at 25 mph, or whatever, the chuff rate is way out at crawling speed.

Is the WOW any better over a wide range of speeds ?.

Just be aware that the WOW is not yet supported by JMRI whereas the Soundtrax is. It is very easy to adjust once you are set up with JMRI decoder pro to set all sounds and speeds using this system and a tsunami decoder.
The WOW is set up using a voice prompt with your throttle.It sounds great just needs a bit more time to get used to it.

ok......now I am REALLY confused. I have a digitrax zephyr to power the locos. the first post tells what loco I have. I also have mdc roundhouse locos and an mmi k27. the mmi was in pieces when I got it, no ddc(cheep). I looked more into the wow decoder. I watched the video on how to set it up. seems easy enuff. $ would be the deciding factor. soundtraxx is a bit less costly, but what is a jmri. another wrench thrown into my more confusing worx. :brill:

JMRI is some computer code company or whatever that have a free downloadable CV altering programme knowns as DecoderPro which is claimed to make CV programming "really easy". It may do, if you understand computers an' all that stuff but having (briefly) looked into it I couldn't understand it at all - but to me just managing to switch the 'puter on is a major achievement !. I'm more of a coal & shovel man myself.

I also use a Digitrax DCS51 Zephyr with MMI K27's & Bachmann Consolidates that I have chipped myself. Some of the later MMI K27's have a sound cam already installed (maybe missing on earlier runs) but gaining access to wire up the cam requires stripping the body down. I haven't attempted this because I've heard that re-assembling the MMI body is "difficult" so I've set up the K27's chuff rate on the Tsunami chip itself.

The DCS51 is allegedly capable of programming the chip CV's but I've had endless trouble until I worked out my own method of doing so. Please PM me if you have any Zephyr programming problems - it can be done !.

HOLY COW !

I came for a nose around this neck of the woods for the first time...
...and I'll be damned, MICHAEL !

I didn't know you had lots of fancy microchips, decoders, chuffers, Digitrax, Tsunamis ... ... ...

It's all bloomin' rocket-science to me ol' bean !

The question is :-

Can an ol' has been like me, get some kind of I.C/steam chip sound thingy...
...that 'll work with good old fashioned 12v analog ?

It doesn't have to be Abbey Road sound quality...
...be nice if it sounded OK though.

I know about speakers, amps, electronics, wiring etc.
What I don't know is if there is a simple/cheap product that I can try out.
Does it exist ?
What brand etc. ?

Last time I heard model train sound...
...was from a PFM system in the previous millenium !
Sounded quite good actually.

??

:moose:

Si.

No DCC, just a good I.C./steam sound effect...
...any ideas peoples ??

Si, while I'm not a sound devotee, the ancient PFM system still sounds pretty great! Years ago, I built an On2 0-4-4t for a layout that my "club" was building. A fellow with the ability to install the stuff put sound into the little lokie.I gotta say that it really was thrilling to hear that engine "strut her stuff". I may be biased but all else I have heard over the years just doesn't compare with that old PFM. Now my "stack talk" is Stravinski and ZZ Top and a bit of Stan Getz.

Carry on folks...

Hi Woodie.

I was going to look into this a bit more...
...but I strongly 'suspect' that the old PFM sound-system used ANALOG-SYNTHESIS to create the sounds, NOT digital-samples.
I could be wrong on this.
But it was kinda made in the era when things just weren't 'quite' digital yet.

I do tons of sound stuff & also design & build my own equipment, of many various types.

A story.
I've heard loads of DACs (Digital to Analog Converters) over the years.
I have several DACS by music companies Roland & Yamaha.
Also a number of CD players by my favorite company Rotel.

I thought I had damn-decent digital sound...
...UNTIL about 2 years ago...
...I heard an old vintage '80s Philips DAC-chip in action !!

Without ANY doubt whatsoever...
...It blew ALL COMERS outta the water NO PROBLEM !!
PERIOD !

They stopped making it in the late '80s because it was too expensive to put in 'consumer' products.
It was also too big.
It also got seriously HOT & consumed VAST amounts of power !

Since then I've used NOTHING but the 'obsolete' Philips DAC...
...NOTHING else comes close.

Progress huh ?

:moose:

Si.

It was analog...back then, digital was something to do with ones' fingers! I stand by my opinions, I know that they are all correct anyway!

Should chicken be eaten with the fingers? No, they should be eaten separately .....

Damn,SuperMod Si has blown my digital disguise cover.

Don't take me for expert - I'm operating right at the edge of my lectronical knowledge (like operating on the edge of a 2 rise ladder but less painful consequences)but Yes, I have been slowly chipping the Chavez heavy haul fleet & fiddling with CV's etc.

It ain't brain surgery, just wiring/soldering dexterity & a bit of 'lectrical common sense. I have found the major U.S. manufacturers are really hlpfull if you encounter problems.

The analogue (no DCC) systems don't impress me, very limited tuning up possibilities (usually non !)& poor "sound" - worse than silence.

Bite the bullet Si & go DCC - vastly superior motor control & slow running. Decent chips have full IQ, reverb, delay time etc. all built in - it's just a matter of finding where the CV codings are hidden. My first MMI K27 was OK out of the box but a bit clunky & awful "semi" IC come analogue sound/motore control. Fittng a new generation chip ABSOLUTELY transformed into an amzing loco. Same with Mr Badman's 2-8-0's. Do it! Now!

Regards, Michael
