arduino as midi=>CV/gate via PureData...PWM = nono

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?

You can use a digital to analog converter (DAC).

In case you want a DIY DAC look at

It's a R2R ladder

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!
