MIDI note cutoff

Dimwit

Hello everyone, new here

I just cleanly installed Kx drivers on SB Live 5.1 card. Everythings fine except MIDI note cutoff during playback or recording.
Let's say I record a C chord and hold the notes for four beats. On another track(and chanel) I record eight bass notes over that four beats. When I playback, the C chord(and the Bass notes) no longer sustain. I can hear a short stab of the chord on beat one and that's it.

This even happens when I'm not recording and just playing the bass notes along with the recorded track on my keyboard controller(which is going MIDI out to my US122 USB interface). In other words, almost any time I play or record anything over a previously recorded track it chokes off all the notes involved.
What's weird is that if I play softly the cutoff won't happen as much or at all. So it seems to be velocity related.

I tested this in two different hosts(Power Tracks 9 and Tracktion) .
I tried it with the 2MB Creative soundfont bank loaded into the Kx and I tried doing it with the Microsoft wavetable synth.
Same problem in each situation.
When I play the patch as a standalone, or if I mute the recorded track, no problems. Full polyphony and sustain.

Does anyone have any ideas towards solving this?
Is there some settings I could tweak in Kx?
I suppose as a workaround I could render each MIDI track into an audio track before I record the next MIDI track, but I feel I shouldn't have to do this.
Or should I?

Your help is much appreciated.

Hmm strange. Myabe you could make a mp3 file and upload both the mp3 and the midi, then we can check what happens on another pc and hear what is actually happening.

Hi Dimwit,

Thanks for the warning. I suffer from EXACTLY the problem you describe and hoped that the KX drivers might solve it. After reading your post I won't waste my time trying KX - thanks.

There are two things I have done to address this problem. One is to change to an ASUS A7N266VM motherboard. This motherboard has a single hardware MIDI synthesiser onboard which is very similar in performance to the SB Live! synth - but it is only a single synthesiser.

I've put the SB Live! board on an old motherboard running Windows 95 OSR2. This works fine, playing notes that would expire on newer motherboards and.or under newer operating systems.

What the actual problem is - apart from being something to do with the Creative hardware - I don't know. As you say, it is a phenomena of long notes being played simultaneously with a lot of shorter notes, it seems to get worse as the music becomes more complex and it seems to get worse the louder the notes are.

All very confusing.
