As that was not an option, I turned to my experience in using sequenced music to achieve this result. Using sequenced music does limit you in many ways, but if used in the right way, it can be very effective and provide the dimention you desire. If I feel lead to tone down and do one of the sequenced songs, I can always play it acoustically. Worship songs can be as effective when sequenced. This gives them more confidence and they become more creative.
Sequencers can also be a major benefit to experienced musicians.
If the group has no drummer, for example, a sequencer can fill the role, especially if it is a small congregation and volume is a problem. When playing live he can only play one of those parts. Musicians should, therefore, not look down on sequncers. It can be an invaluable tool. In fact, many international acts rely on the use of sequencers or other playback facillities.
