I've been living with my Arduino-based detuning modification for quite a while now...and I ∗love∗ it. My only real issue is that, when I switch the Polysix to Unison mode, it's own built-in detuning gets added to my detuning and the results are not always as predictable as I'd like.
So, I went and modified the Polysix to disable the built-in fixed detuning feature. As a result, I now have total control over the detuning amount, which makes it feel more more "correctly" detuned.
The mod is easy to implement (one wire) and easily reversed. If you're interested, you can check it out at:
http://synthhacker.blogspot.com/2013/08/polysix-disabling-built-in-detuning.htmlNote that, if you are only relying on the built-in detuning, I do NOT recommend disabling the detuning. If anything, I'd recommend ∗increasing∗ the amount of detuning, not disabling it. That's an easy mod, too (swap R116 to a bigger value).
Thanks for reading!
