Hmm. I want to prototype something fast, that may ultimately go into a 
PIC.. Its to simulate IC engine noises for model planes..

Basically I want to generate a sequence of pulses whose width and 
frequency are controlled by (sliders? well something I can easily 
adjust)  and apply it to a basic bandpass filter before going to the 
speakers. In analog terms anyway.

What sort of software is available for this?

"for recording and editing;'

I want to MAKE sounds a la synthesiser..

Specifically an API into the sound system...

I guess I can code up the timer tick interrupt stuff.

Try Autozen
http://www.linuxlabs.com/autozen.shtml

Its designed for meditation, but makes cool ufo sounds. :-)

I am a model aircraft enthusiast, so please let me know if you succeed with 
this, or if you are producing any other levels of model aircraft simulation.

Regards,

You will if its sucessful;, see it on RCgrops somewhere.
