SPC topic

I have another question regarding the channels used in a song:

In my compostition there is 3 instruments and the pointers are set as follow:

D4 3F 44 40 26 41 D4 3F 26 41 44 40 D4 3F 26 41 44 40
D4 3F 26 41 44 40 D4 3F 26 41 44 40 D4 3F 26 41 44 40

The problem is that the instruments and the notes at 44 40 never plays. If switch the second pointer with another one then it's another insrument that doesn't play... So I can only have 2 instruments on 3 playing at the same time...The channel in red seems to be the problem and whatever pointer is put there, even if it is duplicated elsewhere (like in this example) it will mute the instrument. I tried multiples combination of pointers but with no results.

Also, there is an unknown sound at the beginning of the song that appeared. It's like a simultaneous note that is played. Could it be because I have put a vibrato and echo at the beginning of the song? I checked all the pointer and played a bit witht the values of the vibrato but the weird sound/note at the beginning remains. I even muted the second instrument to make sure. Listen here


Anyone has an answer to those questions?

Thanks
