Sure, too bad Flash doesn't include Midi and precise timing. FlashMidi only works in windows, it must be installed and uses non standard tricks to install. It's cool for custom art projects, but not for the general public on a web site, as required in my project (must run on standard Flash Player on any platform).
Thanks for the link though, I will try it for my own experiments. >Isn't MIDI designed for this type of application >http://www.alexisisaac.net/products/flashMidi/ > >Ron > >Abe Pazos wrote: >> I don't understand how MP3 can take longer to start.
