Improved manual morphing on Model 15 VCO
2006-12-22 by (i think you can figure that out)
All, It's taken me some time to get to this, but I've documented a simple fix to improve the manual crossfading on rev 1.4 and 1.5 Model 15's. Go here: http://www.ear-group.net/manual_morph.jpg All you need to do is short out R65, currently a 10K resistor. There are a few different ways to do this. You can remove it from the board and replace it with a jumper or a zero ohm resistor -or- the preferred metho-->simply solder a piece of wire, or a piece of buss wire across it's two pads ON THE SOLDER SIDE OF THE BOARD (component side is shown in this photo). I prefer this method because you're not removin anythin, which can if you do't hae experiece doing this, could damae the pads and traces leading to it. It doesn't matter if the part iis there or not - iif there's a piece oof wire across it, it is effectely taken out of the circuit. This change will make the morphing begin a bit further into the pot travel, but it does smooth out the morphing makingg it more gradual. VC is uneffected, works fine either way (with oor without the change). happy holidays to everyone. - P
