This summer with the heat my Ribbon controller got a little hot, and the Velostat (conductive plastic material which is very thin) waving, and made contact in some places šŸ˜’ I still had some and am currently taking it apart to change it, but I added a thickness of adesive tape to consolidate it iā€™m waiting for the glue to dry ā€¦ ---

Itā€™s remarkable how stuff changes when itā€™s correctly grounded. (Iā€™d been trying for ages to figure out what was wrong with my Barton Sallen-Key VCF, a design very similar to the RenĆ© Schmitz MS-20 Filter and therefore, I guess, to the LMNC Performance Filter. Finally I emailed Barton and he made some suggestions, one of which was: Check the grounding on the tip switch of the HP input jack. I did, and found it wasnā€™t. Grounded. Iā€™d completely forgotten to make that connection. Touched a screwdriver between ground and tip switch and everything started workingā€¦) ---

Yesterday some test of my Baby 8, and my schematic is not working good with the reset steps part (it looked good on paper) a on/off/on switch for each step, one on/off is for the reset, but if i not disconnect the steps 9 reset, that donā€™t work i must have to add another switch on/off to choose to select a 8 steps seq or to have the choice for use all others steps reset ![baby 8 - sound bender (2)](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/3X/0/b/0b49d22496e7cc33ed03c35e49dfa72b21a68dd0.jpeg) allready a lot of things on the panel but i need it !

> [@Dud](#): > > a on/off/on switch for each step, one on/off is for the reset, but if i not disconnect the steps 9 reset, that donā€™t work Really? That seems strange to me. If you never get to step 8 then why does it matter whether it resets on step 9? Hm, hereā€™s Ken Stoneā€™s version: ![image](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/3X/0/3/035c03bba561c1f978f97477a0b938034fc82a7f.png) There are diodes on the various lines leading to the reset pin (from Q8, from the sequence length switch, and from the reset input). Did you include such diodes? Maybe try that. (And note the 100k pulldown resistor again! After the diodes, connecting to the reset pin.) ---
