Thank you very much, Seablade. In fact we are using QLab, and a small laptop hidden in
the set with access from behind, for most of the cues. The advantage of a stand alone
unit, with perhaps two or four buttons and a sound allocated to each, is that we would not
be tied to a set sequence or need to find hot keys by touch alone. It's for children's
theatre: if they laugh, do it again. If they don't laugh, move on swiftly. I've been
investigating programmable doorbells. Having used doorbells in the past (pre-programmed)
they have the advantage of being a 'location sound' on stage and giving instant playback
but they can be rather quiet.
