tuning way off

Post by pierrelel »

Hi, all of a sudden, my xoxbox seem to be like 3 octave too low, in fact the only usable sound are with the flashing "up". the solid "up" gives me like a farting kinda sound, and under that I kinda can hear air pumping from the speakers, but certainly no pitch, you know what to check? the voltage on the ic11 pins look about right, 2V for the normal C, 3 for the next.
Thanks.

for reference, as we speak, the regular C is 7.5Hz(approx, hard to read) for the untransposed low C, about 28Hz next, 113.6 next, and finally the Highest is 416.66, so as you can see, every octave turns out to be about 2 that's from the square wave pin of the switch. Also, TM5 doesn't have the range to go from 4 time the freq to twice the freq.
