I want to create simple legato patch but I have lots of problems.>

- I'm unable play Default Sustain Sample (#29 in Splits Smart MIDI Definition)

- When I play non legato it always use Alternate Sustain #1.

- When I use Alternation #1 Key it use Alternation Sustain #2 Sample

- When I use Alternation #2 Key there is no sound.

I'm using Giga Ensemble 3.21.2322.

Can anybody help ?

P.S. I know I can use Alternate sample 1 as default sample and Alternate 2 as Alternate 1. But I want to know where is problem. I'm doing something wrong or there is some bug ?
