2hp: buff mult + unity mixer
Another simple musthave. The 1331 has two great utility functions packed in two hp: a buffered multiple and an unity gain mixer.
If you are using a lot of the same signal, but a voltage drop will make a difference on the result you want to achive - for instance the tuning of your oscillators, a buffered multiple is your best friend. Each output delivers the same voltage as the input.
The unity mixer is the simplest mixer you can think of; three inputs - one out.. easy peasy.
