Hi,
I desolder pins 59 to 64 of the gate array, without cuting the tracks
I made 6 oscilletors using a 40106, instead of six NE555...
Than I solder the outputs of the 40106 oscs to the pins .

BUT... when I move the potenciometer of one oscilletor to control the pitch of an instrument (e.g. Clap)I affect pitch of other instruments (e.g. toms) ... Why it is so

furthermore... I desoder pins from 59 to 64 but I can't control BD and SN pitch!!! Why


Thank you in advance for your kindly reply...
