Depending on how noisy/ how they are constructed, would driving the on/off
type valves with a 10V PWM signal be viable?
It may well create a lot of acoustic resonance in the pipes if the
frequency
is wrongly matched to the valves response time.
Damn you, you've just given me something else to go and play
with/investigate now!!!
More 'Yak shaving' to do (go and look it up, on Wikipedia, you know you
want
to!)
