So I spent a little time getting the chain of 4 shift registers to behave and now have 32 output pins to play with. The glockenspiel I made has 25 keys so things should work out well.
I also wound a second solenoid coil of a slightly different design to the first. I used 12mm nylon for the spool which allowed for some more windings than the first.
The circuit to actuate the solenoids is similar to one shown on the arduino forum.
I am now using a new Arduino Uno purchased from ebay au store microcontrollers and more.
Here is the result with both solenoids connected.
