Getting Z3TA+ tuned to Pythagorean tuning at C4=256Hz (which results in A4=432Hz) is quite an easy task to do, since this soft synth supports scala (.scl) files. The steps in this tutorial can also be taken in any other soft synth that supports scala files.
This tutorial is for anybody that wants to try out this beautiful tuning in a soft synth, I will not go into detail explaining the actual tuning itself. You can read about Pythagorean tuning elsewhere or just try it out and see how it sounds. 🙂 Remember you will have a bad sounding interval between Eb – G#, the fifths and forths are otherwise perfect.
The other aspect of going down from A4=440Hz to A4=432Hz will give you more natural frequencies, I can warmly recommend this to anybody, wheter you’re using Pythagorean tuning or not.
Ok, back to the tutorial. Start by downloading the scala file for pythagorean tuning.
2. The next step is to unzip this file and load it into Z3TA+
3. Then as the third and final step you just need to tune the synth down by 37.5 cents. According to my calculations, the ideal would be 37.6 cents (corrected from 37.4), but the tuning slider in Z3TA+ is a bit coarse, ther maybe some way to fine tune the value but I couldn’t do it. In some soft synths you maybe set the A4 reference frequency, in this case you need to set it to A4=430.5Hz (corrected from 430.6Hz). These are the theoretical values and you may have to adjust these values in practice. Check with a tuner, for example the free CTuner by C-Plugs.
If you were to just tune down the synth to A4=432Hz with equal temperament, you need to go down 31.8 cents or of course set the reference frequency to A4=432Hz depending on the soft synth.
