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

I would say from the debuging that the device is doing 'Note On Velocity-0'
as note off. This is part of the spec.

Hi Mr. Ladisch ,

When I did some debug with Qsynth it seems that filtered the note-off events.

Now that I did a debug directly with fluidsynth I'm able to see the note-off.

Here you are with the aseqdump :

Do these numbers have any meaning?

You said previously that the D4 doesn't generate note-off events?

Could you show the output of aseqdump with a few notes from the D4?

Best regards,

Clemens
