Turning a pot, made my sequencer program crazy

[Alex101]

Hi! everyone.

I have build a version of midibox64 with 32pots (1 AINX), 32 buttons (1 DINX), LTC  and LCD screen (2x16). The PIC was programed successfully and the construction of the modules is OK! Before soldering the 32 pots I have decided to solder only one to see if the midibox realy works. All  the 31 analog inputs (AINX) was connected with the ground (J7). I have also connected the 4 unused pins of J5 (A4,A5,A6,A7) at the CORE module with the ground (J7) to avoid sending random midi events. When i turn the pot right the value normaly goes from 0-127 but my sequencer program starts to play the song that i have loaded. After a few turns of the pot the song stops and then it starts again. What have I done WRONG?

maybe you have the play and stop function of your app assigned to a midi controler , try to change the CC no of your connected pot to another one...

I fixed this problem by connecting pin Vs (J7) with metall chassis ground.

Thanks anyway  ;D
