Re: problems loading sounds from sysex

2008-10-21 by narfman96

Hi Peter,

The 4d in the 7th byte tells a CZ1 to switch into "Normal Mode" to 
accept single patch data. The CZ5000 has no idea what this string 
means....

The 21 (7th byte) in the second message tells a CZ1 that this is a 
CZ1 patch dump from another CZ1 or a PC. The CZ5000 has no idea what 
this string means either....

The 20 in the 7th byte tells the CZ5000 this is a CZ1 patch dump. 
Great job figuring this out by inspecting the other file! I found all 
this info in the CZ1 midi spec.

The envelopes will be messed up on some or even most of the patches 
for sure. The CZ1 has velocity scaling for the DCO, DCW, and DCA 
envelopes. The CZ5000 is wide open all the time. If any velocity 
scaleable pitch envelopes are used the CZ5000 will really sound out 
to lunch. I made most all of these CZ1 patches from CZ5000 patches 
and added the velocity settings. I probably have the original CZ5000 
patches stored somewhere in my libraries if you want them I could try 
and dig them up. It's been a while.

Hope this helps, Fran aka Narfman
