Yes ipads are being used and why the hell not? As long as people are encouraged to sing and play. I dont think the Folk Police are in position to impose rules about this, any more than the instruments played and music performed. Electronic instruments are being used more often such as EWIs and synthesisers and why not? a guitar or accordion is no more authentic to accompany a tradional song. it is not as if the oral tradition was art risk. We learn songs and pass them on by use of digitsl media these days, if it helps to have the music in front of you then its better hou do that than not to play at all.
