Disklavier

Thanks Carol, The real 720 DSDD 3.5 disks work just fine.  Now I am 
busy finding songs on this site that sound good.  I am not familiar 
with MIDI specifically. I tried downloading some MIDI files from the 
internet and then converting to ESEQ with DKVUtil... some work just 
fine, others do not.... Is there a way to look at the attributes of 
the file to tell if it will play on my MX80.... some say "solo" 
others say "ensemble"... does changing this attribute make it play?  
Must I only use "solo" midi files on the MX80 or is there something 
else to look at.. Thanks.
