A string/synth pad for waltzes would be great but so too would some acoustic and electric piano solos in 3/4 time...especially in the jazzy stuff. In fact whole lot of 3/4 solos for many instruments would be great.
And on the subject of chords how about the facility to write chords with (no 3rd)? There are so many things I could think of but I just think the program is fabulous and the creators should be congratulated. The way the business handles post sales inquiries is also great. The staff are courteous and obliging..
