Mini pipe organ

Using Arduino Project Guidance
#1

I would like to make a simple midi, mini pipe organ but the first thing I thought of was the price of the solenoids. I'm guessing I would need about 40 individually moving "plugs." Would there be a way to do this without paying $6 per solenoid?(The cheapest I've seen them). Variability would be very good to have but not entirely necessary.

Maybe an alternative to solenoids more specialized for large arrays?

Thanks

If time is abundant you could visit a scrapheap to see what is in 'store' there.

can you post a link to those you found yet? (to get the specs)

Do you need different sizes, or one size fits all ?

Would these work? - Scotty
