The First Sunday in Advent was a couple days ago, various communities have started having their Santa Clause Parades, and we are all starting to think forward to Christmas, it has got me thinking about what is really important. 

You are working on an organ and a bunch of stops and couplers scattered throughout the console aren't working. The 4th DK in the first column, the 1st DK in the 3rd column, the 3rd DK in the 4th column and so on. It seems random. Pull out your Technical Manual and compare the stops and couplers that aren't working to the Stop Rail Wiring Table. You may discover that it isn't random after all, there is a pattern. In this case the 4th tab in every byte (8 tabs) wasn't working. 

Organist calls, tells you that when they turn on the Swell Diapason and press a key, nothing happens. The organist is able to tell you that the display for the Crescendo shoe is working, and Pedal stops play, therefore, you know that at least you have a 'Yes' to both 'Is it plugged in ?" and 'Is it turned on?'. You also have at least some of the answers to 'What exactly happen?'.  What you don't yet know however is; where exactly is the problem. 

3) What exactly happened?

Several years ago we had a system in a church and every so often there would be a cipher. Nobody could figure out what was going on. The builder was in there repeatedly, we even stopped in at the church on our way to the Boston AIO in 2001, all to no avail. It wasn't until we got a 'Yes' to a couple of the questions below that we figured out what was happening.

Welcome to Part 2 of my series on questions to ask when trouble shooting. In the first part you asked the question "Is it plugged in?", and you know your power supply is good, you haven't lost ground, and everything is connected, what is next?

2) Is it turned on?

Under this question I would include not just, "Did you turn they key?" (don't laugh, it has happened), and "Did you physically turn on the drawknob?", but also "Does the computer know the organist did something?" and, "Is the circuit board receiving/processing data?".   

Back when I was in college studying electronics, the school I was attending had a talent competition one day. I brought my keyboard in to play, cheap thing only 61 keys, not even touch sensitive, but I was a poor student and it was free. I got myself set up on the stage, went to play, and got nothing. I glanced at the On/Off button, it was on, I glanced at the power cord, I had forgotten to plug it in. This demonstrates the first two questions every service person needs to ask when trying to solve a problem. 

To all the people who were at AIO in Boston this year, it was great seeing you! I don't get out of the shop very often so it is great being able to put faces to voices I've talked to over the years. 

In honour of Classic's 40th anniversary, I've been looking back at some history and came across something I thought was interesting. I remember, back when I was in public school, Casio coming out with this keyboard which used colours associated with keys to teach people how to play the piano. Later on these keyboards started giving you feedback whether you played the right notes. I thought it was a neat idea, so did a lot of other people, and Casio made a lot of money on that product. Interesting this is, Henry is the one who invented the feed back system.  

Given the same simple melody, how would different composers sound? A friend of mine posted this YouTube video on her Facebook page. It's not organ music, but it is enjoyable. 

MIDIWorks (the Hauptwerk MIDI branch of Classic) showcased our products in this year's AGO Convention in Houston, Texas. For those that don't know, AGO (American Guild of Organist) hosts a convention every 2 years where organists can go to meet, connect, and explore the most up-to-date organs and organ based products/systems.
