sfz player skips notes

I have two groups of samples which I try to organize in sfz file. My goal is to make "round robin" kind of sample triggering. I set sequence length to 2, first group to seq_position 1 and second group to seq_position 2.

<group>
ampeg_decay=12
ampeg_sustain=0
seq_length=2
seq_position=1

<region> sample=XP30 Bass A\Xp30_FingBassA_E2.wav lokey=36 pitch_keycenter=40 hikey=40
<region> sample=XP30 Bass A\Xp30_FingBassA_G2.wav lokey=41 pitch_keycenter=43 hikey=46
<region> sample=XP30 Bass A\Xp30_FingBassA_D3.wav lokey=47 pitch_keycenter=50 hikey=52
<region> sample=XP30 Bass A\Xp30_FingBassA_G3.wav lokey=53 pitch_keycenter=55 hikey=57
<region> sample=XP30 Bass A\Xp30_FingBassA_C4.wav lokey=58 pitch_keycenter=60 hikey=61
<region> sample=XP30 Bass A\Xp30_FingBassA_D4.wav lokey=62 pitch_keycenter=62 hikey=72

<group>
ampeg_decay=12
ampeg_sustain=0
seq_length=2
seq_position=2

<region> sample=XP30 Bass C\XP30_FingBassC_G2.wav lokey=c2 pitch_keycenter=g2 hikey=g#2
<region> sample=XP30 Bass C\XP30_FingBassC_C#3.wav lokey=a2 pitch_keycenter=c#3 hikey=e3
<region> sample=XP30 Bass C\XP30_FingBassC_F#3.wav lokey=f3 pitch_keycenter=f#3 hikey=g#3
<region> sample=XP30 Bass C\XP30_FingBassC_B3.wav lokey=a3 pitch_keycenter=b3 hikey=c4
<region> sample=XP30 Bass C\XP30_FingBassC_D4.wav lokey=c#4 pitch_keycenter=d4 hikey=c5

I load it into sfz player, and when I play keyboard, some notes are silent in random order. Same with Drop Zone and Dimention LE.

Here is the archive with samples and sfz file:

    Looking really quick... You have an un-even number of regions between the two groups. Are you missing a region in the second group?

    Yes, first group has one more region... Just noticed that, thank you for pointing out. Does it mean that groups must have equal numbers of regions? First sample set has 6 key zones and second set has only 5 zones, so where do I get 6th region for the 2nd group?

    It's not required that they have the same number of regions, however the extra key zone in group 1 will sound on/off like a gate because there isn't any sample within that zone on the second sequence. You could just put that extra region in it's own group to solve the issue.

    I created 6th region in the second group but it didn't help.

    <region> sample=XP30 Bass C\XP30_FingBassC_G2.wav lokey=c2 pitch_keycenter=g2 hikey=g#2
    <region> sample=XP30 Bass C\XP30_FingBassC_C#3.wav lokey=a2 pitch_keycenter=c#3 hikey=e3
    <region> sample=XP30 Bass C\XP30_FingBassC_F#3.wav lokey=f3 pitch_keycenter=f#3 hikey=g#3
    <region> sample=XP30 Bass C\XP30_FingBassC_B3.wav lokey=a3 pitch_keycenter=b3 hikey=c4
    <region> sample=XP30 Bass C\XP30_FingBassC_D4.wav lokey=c#4 pitch_keycenter=d4 hikey=d4
    <region> sample=XP30 Bass C\XP30_FingBassC_D4.wav lokey=d#4 pitch_keycenter=d4 hikey=d5

    Both groups have 6 regions now but notes are still being skipped.

    Problem solved.

    Turned out both groups must have identical lokey and hikey numbers.

    <group>
    ampeg_decay=12
    ampeg_sustain=0
    seq_length=2
    seq_position=1

    <region> sample=XP30 Bass A\Xp30_FingBassA_E2.wav lokey=36 pitch_keycenter=40 hikey=40
    <region> sample=XP30 Bass A\Xp30_FingBassA_G2.wav lokey=41 pitch_keycenter=43 hikey=46
    <region> sample=XP30 Bass A\Xp30_FingBassA_D3.wav lokey=47 pitch_keycenter=50 hikey=52
    <region> sample=XP30 Bass A\Xp30_FingBassA_G3.wav lokey=53 pitch_keycenter=55 hikey=57
    <region> sample=XP30 Bass A\Xp30_FingBassA_C4.wav lokey=58 pitch_keycenter=60 hikey=61
    <region> sample=XP30 Bass A\Xp30_FingBassA_D4.wav lokey=62 pitch_keycenter=62 hikey=72

    <group>
    ampeg_decay=12
    ampeg_sustain=0
    seq_length=2
    seq_position=2

    <region> sample=XP30 Bass C\XP30_FingBassC_G2.wav lokey=36 pitch_keycenter=43 hikey=40
    <region> sample=XP30 Bass C\XP30_FingBassC_G2.wav lokey=41 pitch_keycenter=43 hikey=46
    <region> sample=XP30 Bass C\XP30_FingBassC_C#3.wav lokey=47 pitch_keycenter=49 hikey=52
    <region> sample=XP30 Bass C\XP30_FingBassC_F#3.wav lokey=53 pitch_keycenter=54 hikey=57
    <region> sample=XP30 Bass C\XP30_FingBassC_B3.wav lokey=58 pitch_keycenter=59 hikey=61
    <region> sample=XP30 Bass C\XP30_FingBassC_D4.wav lokey=62 pitch_keycenter=62 hikey=72

    Even if pitch_keycenter values are different, key zones match in both groups. Now all notes sound without skipping.
