PS:
Did you test
amidi -p hw:0 -S 'F0 44 00 00 70 10 20 70 31' -r save_patch_20.syx
or
#!/bin/bash
finalfile=save_cz101_internal.syx
for loc in 20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F
do
tempfile=save_${loc}.syx
amidi -p hw:0 -S "F0 44 00 00 70 10 $loc 70 31" -r $tempfile -t 5
cat $tempfile >> $finalfile
rm $tempfile
done
Even though the title says CZ-101, this is also the procedure to use for
a CZ-1000.
