I just installed the ModyPoly in my Poly 61 and i also did the unison button mod, as well as adding attack and decay parameters from this:
(Attack + Decay)
https://tubbutec.de/blog/poly-61-cv-injection-points/
(Cutoff + Res)
http://voiceofsaturn.blogspot.com/2008/ ... ly-61.html
I love the results, however, the transformer gets fairly hot if switched on for 1h+ and i can smell dust...
Im not sure why this is happening, any ideas? Im taking the -15 and +15 from the resister and diodes south of the transformer labelled on the power board.
Im leaning towards trying purely just the Tubbutec mod and swapping/dismantle the cutoff and res mod from the voice of saturn site- If i did this, would i be able to control the cutoff with the CV injection from both the ModyPoly and a pot?
Also, i installed the unison button but its not really working... when i switch the synth on the LED comes on like unison is selected, when i switch to POLY the LED goes off and i hear a change but i cannot get back to unison using the button.. This possibly tells me the button is broken but does anyone have any thoughts on this?
Thank you in advance, sorry for the long questions, any help and advice would be much appreciated as i dont want my synth to blow up


Cheers!!
