<p>urbanspaceman: The instructions I wrote apply directly to the Drone lab. If you want and Casper doesn't mind I can make a PDF of his schematic and board graphic and show where it would be applied using my step by step guide above. In the guide I can then show clearly how to do normal or exponential CV control, CV control of other parts also. In fact I may go ahead and make it with a bunch of schematics and howtos to add other bits of logic. For example it would not be hard to add an enhanced distortion, fuzz block, or a set of LFOs that can be used with the new CV inputs to animate controls, a phased mixer using 4 photocells (this one is really cool and simple and the dronelab is already setup to basically do it), ring mod or like Tom Bugs Weevil cascading ring mods (on the drone lab it would be ring mod drone 1 and drone 2 and then be able to ring mod drone 3 and drone 4, then be able to take the outputs of both of those ring mods and ring mod them together, the stacking effect is quite neat), also voltage starving (works GREAT with the 40106), touch plates for certain bend points I found, there are many other things that can be done and I can show hints on how to do it, like another cool one is to put a envelope follower into the signal chain. A lot of these would require satellite boards to go with drone lab because of lack of space. I think Casper had an idea about this. I got the way I am going to do it but its a bit radical in change.</p>
<p>Ok once again I find myself running my mouth too long, sorry for that. Tell me if you want any of this, right now my time is a bit limited but I can easily at minimum do the CV control howto PDF this weekend. The only limitation will be how many CV inputs you want and where you wish to place them. If you are going to use a 1/4" jack and want to use the prototype area you are only going to be able to fit one. If you use the prototype area to solder in flying wires and then drill holes in your case for a bunch of jacks you can do that too. Oh, and if you want attenuation (which is nice but not totally needed) you will need an area to put a pot. You can use a pot that sticks out the back that solders into the prototyping area.
