Researching this on the net is pretty confusing and there doesn't seem to be an up to date thread on this on the forum. I hope this is an appropriate forum or if not could you please direct me to one?
I am mostly self taught on keys and have a motif XS7 and Nord Stage EX on keys and lead vocals for a cover band. I am about an intermediate (grade 4 out of 8 in Australian Music Examination Board terms) in terms of formal piano training. I mainly play by ear and fill in gaps with you tube or other internet info re songs I cover in my band.
I am having piano lessons now with a teacher but there must be an way to improve playing and sight reading with a MIDI keyboard and piano tutor software.
