Dear Tony,[ and  diy list ]
the replies to your question have been very usefull .Now all I need to
do is to make some money to pay for all the books that I need to get ! 
A site that has some interesting books is at

BTW does anyone know if the Korg Ms10 filter is the same as the Korg
ms20 filter.I had to repair an Ms10 recently, and the filter does sound
unique .
