I promised to myself: no more MOD hacking, no-one will convert Amiga MODs.
And then this happened...
Cremona.mod ->
Cremona.AGIOriginal file wasn't tweaked in any way. Just a couple of command-line parameters to make drums out of samples, and reorder channels

--instr-note 5 13 --instr-note 11 14 --instr-shift 7 -12 --auto-drum-offs 1 --channels 2,3,4,1
EDIT: Even better with built-in arpeggio for those chord samples:
Cremona.AGI with arps!
Still, just command line parameters...
--length 500 --instr-note 5 13 --instr-note 6 14 --instr-note 5 13 --instr-note 4 15 --instr-note 11 14 --instr-shift 9 12 --instr-shift 12 12 --instr-shift 13 12 --instr-arp 1 047 --instr-arp 2 037 --instr-arp 12 037 --instr-arp 13 047 --auto-drum-offs 1 --channels 2,3,4,1 cremona.mod out_cremona.ags
Sadly, an AGI sound file that long has problems fitting in memory, I had to add a --length parameter to limit the number of note rows processed. That's unfortunate.
