[LAU] FluidSynth fails to sintetize more 85% events generated by Drum machine ALESIS D4.

I'm running fluidsynth/qsynth in a 64studio distribution.

I'm generating MIDI events from a Drum Machine Alesis D4 directly to
fluidsynth through a MIDI In port and fluidsynth fails to sintetize more
than 85% of the hits on the PAD.

Facts :

1- Fluidsynth is receiving MIDI events from every single hit on the PADs.
(checked with amidi & fluidsynth -v)

2- Fluidsynth is able to reproduce every single Midi event if it's generated
by a Midi keyboard or Virtual Keyboard.

3.- If I connect the Alesis D4 module to a Hydrogen dumr machine , it
reproduce and sintetize every single stroke without problem.

4.- After do some debugging I have been able to see the following :
