Thanks for all this time and effort Mr L. - it must be the 1st new UK Cathedral organ to have such coverage during its earliest stages. The new 'chambers' are interesting - Mr Hope Jones would be pleased. I would also be interested to know some of the wind pressures. The Swell and Choir pipework looks as if it will be recessed quite deeply. Will the sound have to be 'pushed' quite hard to get out?

PS Please don't take this the wrong way - one of the most effective instruments I have heard - of its type - is ingeniously wrapped around the inside of the most impossible of chambers.
