<p>I just found this schematic on the electro-music DIY forum. It shows a VERY simple method for adding cv control of the oscillators in the 40106 chip. All of the oscillators n the DRone Lab are generated using a 40106. If you have questions about this schematic, please post below and I'll try to help.</p>
