Dear Diyer,
After spent lot of time testing different TR909s and tried to find the best solution to improve ACC response on the Nava we finally found it.
We designed a small board to replace IC114 and IC111.
This board is a simple multiplexer with amplifiers (two TL074s) as sample hold. With this mods we can have now very accurate accent response.
Here are the boards:
I know what you are thinking :
"The components are SMD, it' s hard to solder...".
Totally wrong, it's very easy taking your time and with the right tools.
Have a look on those tutorials :
https://learn.adafruit.com/smt-prototyp ... ng-an-soic
https://www.sparkfun.com/tutorials/96.
The Mouser BOM for the needed part to build
both boards is available
here.
All Diyer that already built the Nava will receive a free set of two boards (availability: October the 16th 2017). Add your name and order number on this sheet and as soon as we get the board ready it will be sent to you 
Boards available in the shop
Best regards,

Great news!
I'm not able to fill the form though, it seems to be in "read only".
Thanks!

Hi Vincent,
Great news!
I suppose with Order Number you mean the order reference on the invoice? Because for the Nava it seems to differ from what I saw in the order history on your site.
Anyway I have filled the gdoc, looking forward to the mod.
Thanks!

Will this board be included with the new kits? Or is it already integrated on the board?

Very nice of you to send the boards for free! And yes, SMD is scary before you try, but after the first attempts its not bad. Buy some cheap SMD practice boards from Ebay
