Garritan legato implemented incorrectly

[lazerlike42]

GPO has two sets of patches - the regular patches, and special ones called notation patches. The samples are the same, but the key switches and controls you use to activate different articulations are different. Now Notion is set up to use the notation patches.

The problem is that it then goes ahead and uses the standard legato controls. In standard patches, legato is played when the sustain pedal (CC# 64) is activated. This is not true of notation patches. I believe (though am not 100% sure) that in notation patches CC# 68 activates legato. I thought a simple fix for this would be to go ahead and edit the rules file so that it would use controller 68 instead of 64 for slurs. However as I said, I'm actually not even certain that CC# 68 controls legato, and so I think (perhaps) the bigger problem is that the notation patches are being used rather than the standard ones.

I think it's time to call pcartwright in.
I am sure he can help us to leave this tangle safely.

I had said in my first post that after changing the rules to send CC# 68, it was still also sending 64. I've fixed this, as the problem was simply that I left the backup copy of the rules I made in the rules folder and so it was doing what both files said. Now it's only sending 68.

However, in some experiments I've done with the Aria player and my MIDI keyboard, I'm not certain that CC 68 actually does the same thing in the notation patches as 64 does in the standard ones.

You can change the samples used to the Standard instead of the Notation patches (I also found that certain techniques don't translate as well or as expected with the Notation patches). The templates for each instrument can be seen in the GPO folder (same location as the rules folder). Just open the file (GPO will appear to be a simple VST instrument track), open the plugin window, adjust the sounds as needed, and save. I would make a back up of all the template files first just to be on the safe side.

I remember that getting the rules just right for legato was a little tricky. Give me a few days and I'll dig back into my rules file and see what I did to correct the legato.

Thanks, pcartwright. I would be very interested to see what you have.

I've come up with something that seems to work, at least as far as I can tell. I added a second controller (#21) to each under-slur rule so that it turns the note length up for these notes. At first I couldn't find a value that seemed to produce the same results as the standard patch CC #64, but I've gotten what are - as far as I can tell - good results from a value of 114-115 (which works out to be about 90% on the nob).
