Hi, For real practising I use the jazz:long notes style since it has no comping(thank god) and is good to hear the harmony and do your things on the song with your instrument. BTW I put rhodes instead of piano and its reeeally useful. As far as I know, this is the only style that the harmonic comping instrument plays plain chords... Its a swing style, so I would like to know if I can make other straight styles (bossa,latin...) like this to practice as well, as I haven't found yet. All are clerky comping pianos and so... Thanks!
