Showing Two Slides side-by-side in a slide presentation

I won't be animating the slides.  It will be run on a laptop with no other displays connected. 

The problem with dumping the slides to images, etc is that my presentation is going to change every week.  I lead worship and I want to use the system to display lead sheets.  However, I don't want the delay between slides that exists when I only display one slide at a time so that I can continue playing piano and just have to press the space bar or arrow buttons to go back and forth between various pdfs of the music.  Creating a new show like that every week would get old VERY fast.

The add-in that is linked above does what I want except I'm a cheapskate and don't want to pay for it.

Do you know if VBA allows you to program "new" slide transitions to get the effect that I'm trying for?  I've not had a lot of luck finding any information on macro programming in PPT (it abounds for Word and Excel!). 

Thanks.

Hmm.  How you'd go about this depends on a couple of things.

For example, do you want each of these two side-by-side slides to have its own animation settings, or are they both static?

And how will you give the presentation?  On a single projector or on two, one for each show?

If on one projector and the slides are static, it seems to me the best bet would be to use a macro to create a new presentation from your original; for example, export the entire presentation as a series of PNG image files, then create a new presentation and insert PNGs 1 and 2 on the first slide, 3 and 4 on the second and so forth.  This shouldn't be too difficult to automate with a bit of VBA.

If on two projectors, you may or may not be able to run two presentations from one PC.  If your hardware permits it, you'd need some code to trap slide advances in presentation 1 and automatically trigger then in presentation 2.
