No lock when length set above 8 steps #95

Shayshez commented 6 years ago

Just finished to build Turing machine mk 2 and it's almost work perfectly... when I set the length between 2-8 steps everything work as it should but if I set the length above 8 (12/16) there is no lock, instead if I rotate the knob fully clockwise it set all the steps on low value and if I set it fully counterclockwise it set all the steps on high value (like the operation of the write switch). I built it from mix of 2 kits the beck pcb is rev 5 from thonk and the front pcb is rev 4 from magpie. https://youtu.be/3f1u6bIiEZY

I'm having the same problem that i've been trying to fix for over a year now. Mine does not lock at 6 or above, the notes then leave the sequence one at a time every time it loops.

Well try that TL074 next to the DAC.. or the socket it goes into.

good luck man

Thanks for the pointing me in that direction, i'll reflow the joints there again and see if swapping the ic with a new one will help.

swapped the TL074 with a new one and it's working fine now. Thanks Deepiain!
