no sleep till brooklyn.

the 10K resistors fixed it, thanks

aah yes inputs..10k resistors. check.
will do after some sleep, its 3.a.m.

i'm building a simple midi fader box with an ATmega328 and 4051 multiplexer.The analog input goes bananas if i get close(with my hand) to the 4051 "input select" pins or their digital inputs on the ATmega. So far(since this pivture was taken) i've added a 103 capacitor between Vcc and GND on the 4051 and a 104 between AREF and GND on the ATmega.

I'm going to buy a midi-cv/gate converter and save the pain.

Maybe i'll play with a DAC and/or the ladder at some stage, but for now i want to play with the synth!

thanks for the replies!

I set up a patch that roughly matches a Hz/V scale for my yamaha cs/5, but the yamaha freaks out on the PWM..A multimeter registers the correct voltages however.

Is there a way to send stable voltages instead of PWM?
