Peter's Pearls / Re: No__10____Drawbars – (v) AR Lightbars
« Last post by Peter Anderson on Today at 12:03:37 PM »
No problem to me.

It should help other members to realise just how all these things relate to one another and how these articles can assist them, in benefitting them, by appreciating what is available on our Yamaha AR organs, which although they are over 20 years old, still take some beating.

It is so valuable to find a source, like this AR-Group, that can provide such a wealth of broad detail, enabling them to gain the maximum advantage of their instruments and their regular enjoyment of them.

Roger,

Thanks for your comment.  I do enjoy putting together things like this to get them to sound as I want them to.  I don't read music, so I am able to put whatever comes to mind into my music.  I used to play piano in a 'pop' band as a youngster (in Kenya) and we used to have to play 50 songs a week, which I did just following the chords the guitarist had written out for us.  Been there, done that.  So I am inclined now to spend my time on the technical side of things rather than just playing something.  To give you another example of what I do, click this LINK which will take you to my arrangement of "All You Need Is Love" by The Beatles.

Peter .. sorry, we seem to be digressing from your 'Pearl' on the AR Lightbars!

Hugh,

You’ve obviously put a lot of work into “A Whiter Shade of Pale” with great success. I like it a lot.

Believe me, Peter, when I say there is no-one more amateur at this game than me. Whilst you might be an amateur in the strict sense of the term, the wealth of knowledge you display in your posts on this forum is profound and I would say expert is a more accurate definition of your status. I have learnt a lot from Peter’s Pearls and look forward to learning a lot more from yourself and Hugh, another expert, as well as other contributors. This forum is truly a valuable resource.

If you read “About Roger Mardon”, which I have posted in the Members’ Section ...

http://www.ar-group.org/smforum/index.php?topic=3060.0

... you will see my very amateur background. And while you’re there can I persuade you to offer some comment on the quality of AR orchestral sounds. I would value your opinion.

Best regards, Roger

PS. I have just noticed that my original post was wrong. I referred to 00 0400 000 as 4ft to max when I should have said 4ft to half way!

Peter's Pearls / No__87____Regular Warm Up
« Last post by Peter Anderson on April 21, 2018, 04:25:15 PM »
Regular Warm Up

We all realise that athletes and sports people, will always warm up before commencing their activity, we need to recognize that as organ playing can be quite physical, we need to consider doing the same.    Therefore we need to warm up as well, before we spend a long spell at the AR.

It won’t come as a surprise that our fingers are one area that we fail to exercise properly.    If you are like me, with one replacement knee joint, (which is brilliant by the way) you have to maintain an exercise regime or you will get stiff.

In the following Replies we’ll explore some ideas to help us in this area.

We appreciate your input and observation, Roger.    We are only amateurs, easily prone to mistakes and errors, but we are prepared to admit when we are wrong.      We will still persist in supplying helpful posts to further the interest in the Yamaha AR organs.    So please keep a watchful eye on us!

My guess is that Yamahas different approach to 'drawbars' probably had something to do with copyright and patents, etc, at the time.

I now notice that most organs/keyboards with said drawbars, are numbered clearly and identically to the same way as the original Hammond ones.   Interesting!

You have referred to this paragraph above........

Quote
There is a standard shorthand to define drawbar settings written in this form for a Hammond 00 8040 000, which means pull out the 8’ to maximum and the 22/3' to half way.   
N.B. On an AR100 this would be written 08 0040 000, because the 5 1/3’ swops its position with the 8’.


That paragraph is now completely accurate, but you quite rightly point out that orignally I referred to the 4' and not the 22/3'.  We need your sharp eyes!

Peter/Hugh,

Thank you. I thought I was right.

I have no trouble understanding the difference between Hammond and Yamaha volume settings, but what a pity Yamaha couldn’t follow Hammond’s nine (0 to 8) position settings. All the touch controls on the EL90 also have seven settings - must be Yamaha’s favourite number.

Peter's Pearls / Re: No__81___Basic organ stops explained
« Last post by Peter Anderson on April 20, 2018, 06:42:28 PM »
Non-Speaking Stops – continued.

2   The Intramanual Couplers

Intramanual couplers are different from intermanual couplers, as they couple one note on any of the keyboards (or pedalboard) to another note on that same keyboard at a lower or higher pitch.

These couplers allow you to play stops of the organ at a different pitch level on the same manual where the stop is located. They are often referred to as Sub Couplers or Super Couplers.

So when we play Middle C, we hear that note and either the lower C or the Higher C, depending on whether we have selected the 16ft or 4ft Intramanual couplers.   Of course it is possible to select both of these couplers at the same time.

This becomes a short cut way of selecting the 8ft, 16ft and 4ft stops that we first described earlier.

However, if we select an 8ft trumpet, this Intramanual coupler enables us to double or treble the voice on that same keyboard by adding the 16ft or 4ft Intramanual coupler.

On some pipe organs, you may find the stop simply marked Octave and selecting this automatically adds the note an octave higher.

Less common is the stop labelled Sub Octave and this one selects the note one octave below the note you play.

Note:     by activating the Swell to Swell 16' coupler (Sub), the stops selected in the Swell manual will sound one octave lower than the key played on the Swell manual, but an exception is the first octave where the lowest 12 notes will only sound at unison pitch.

Similarly with the Swell to Swell 4' coupler (Super) activated, the stops selected in the Swell manual will sound one octave higher than the key played on the Swell manual, but an exception is the last octave where the highest 12 notes will not play if the selected stop is 2' or shorter.


On our AR we can create this coupling effect by selecting an 8ft Trumpet as one voice and a 4ft trumpet as a second voice.   It just needs more pre-planning for us and some careful thought as to how to achieve the end product.

And in the final Reply we remind ourselves of the third non-speaking kind of stops.

Peter
