The 'final' version of PSALM is now complete and available for download. This is the version that was shown in my project presentation, and may still change slightly when further testing is done to fix bugs. This is it for features though. (At least for this project... My current church (Jubilee Coventry) and a church affiliated to my parent's church (Oxford Community Church) have both expressed interest in using either my program, or in using something that my program may evolve into the solution for.)
The main new feature in this 'proper' third & final increment is the song recommender. Build your setlist (the bottom-left list), and click 'recommend' to open up a new dialog. Here, you can choose whether the next song should share chords (making it easy to flow between songs), be of a certain theme(s), or even have been played before in setlist history (see the history.xml file included in the download - this is my record of most of the 'sets' I have personally played in over the last 12 months). You can alter how important each of these factors should be in compiling the recommendations, as well as how strict the recommender should be (ie. returning more/less results).
Hopefully, that explains how to use it. Before you jump into using it though, PLEASE note that this is just a tool, nothing more. If you are thinking of using my program - or any other computer tool - to run/guide/build your set, or even church service, think again. It is imperative that the 'Worship Leader' is in fact God. And he uses people to conduct these services. He did not choose computers to do it. There is far more to worshipping God than choosing a bunch of songs that 'fit criteria' like the way my program might see it. Read 'I did it His way' by Tim Hughes - this explains more of what I mean. The Holy Spirit should be conducting our worship of God, not any computer program, let alone mine!!!
At the heart of what I have built, is a desire to worship God 'better', and to help others in worshipping Him 'better'. It can help in finding songs, or displaying them as a prompt. But sometimes we must put the computers, the songbooks, and even the guitars away. We must allow God to speak, especially since he may speak in "a gentle whisper" (1 Kings 19:12 (NIV Bible)).
Anyway, thank you for bearing with me through that notice.
