Replacing a harp part

My full-orchestra piece has a rather crucial harp part, but we can't get a harpist.

The part includes lots of glissandos... mostly scales, but also some dim7 chords (e.g. [Db C# Bb | E Fb G A#] ) and some weirder harmonies. It also has some small homophonic solos (melody and arp'd accompaniment).

I'm kind of at a loss what to do. We could easily set up a synthesizer on stage, but playing a fast Bb minor scale, for example, is pretty tricky on the piano...

The thing is we hardly have spare strings either :laugh:

4-4-3-2-1, balanced against WW in pairs, 2 tpt, 2 hn, 2 tbn, perc & timp. And harp.

This one.

(btw, I hope I've written the harp pedal changes correctly. Although it's purely academic now ;))

Well I was told we'd have a harpist (or at least a harp) before I wrote it, but it turns out we can't get one due to budget problems.

I think I might go with the synthesizer idea. On some synths you can set up chromatic transposition right? Like where you can glissando all the white keys and it comes out as, say, a D nat-minor scale instead of A nat-minor?
