Which Software Is Closest To Yamaha Qy Sequencer? Options

[yogurtboy]

years ago i owned several Yamaha QY MIDI sequencers: QY-10; QY-20; QY-300; etc...

i really enjoyed the ability to quickly set a chord progression in a certain style, then practice over it.

there must be some software for the Mac that accomplishes this? NOT Garageband!

for example, i want to be able to:
1) set a chord progression, like: | ii | V7 | I | I :|
2) pick a style: Jazz
3) pick a key: A

...then press PLAY an practice over top.

More of an accompaniment tool than a sequencer or studio, I suppose

Any suggestions?
