PAiA V/Hz Interval Scaler

Post by davebr » Thu Dec 26, 2019 8:07 pm

A customer asked me to make him an interval scaler for a PAiA. PAiA is a V/Hz so you can't just add or subtract voltages from the CV. You can, however, multiply them with scale factors. -1 octave or +1 octave are simply multiplying by 0.5 or 2. He wanted a major and minor third and a major fifth. Those you can create by multiplying by 1.1892 for a minor third, 1.2600 for a major third, and 1.4884 for a major 5th.

I made it in a 2-wide panel with one CV input and four separate scalers, each with 6 settings and 2 CV outputs. It came out very nice. I have a demonstration video with four 4720 oscillators on my PAiA Hz Interval Scaler page.

dave, this is beautiful, as is all your Paia work. wish my Paias were up the priority chain far enough to warrant such a rework.

just watched the video, so sick. maybe this is moving up the priority chain.
