NAVA 95% Complete, couple of questions. [UPDATE now 100%]

Discuss Nava construction and related issues
  • Mux boards arrived today, got them soldered and all the voices play which is cool. I am getting the Open hat decay issue that others seem to have. Once the caps arrive I will try implementing Loons parallel cap addition to see if that helps: via this thread - viewtopic.php?f=24&t=2064&p=12124&hilit ... cay#p12124

    I decided to go with these rubber feet from Amazon: https://www.amazon.com/gp/product/B07PH ... UTF8&psc=1

    As well as the suggested power supply:

  • Unlike the recent Nava enclosure from Erica Synths, the very first run of cases from user "happymum" had four 3.5mm holes to fix these rubber feet:

    They were removed from the BOM but I am still using them for the Erica Synths case:

    Very cool! Thank you for that, if the rubber stick-on ones don't work for me I will grab those.
    I finished the build today using Looms advice and tested a few different caps in parallel with Muxboard IC111 C6. I landed on using a 10nf ceramic and the hihats now have their decays back. I also added the 6.8nf cap to Muxboard IC114 C6 for the kick decay and it seems to have beefed up the kick as well.

    Very happy with this build. Once the Chia Shin knobs arrive the whole package will be complete! :D
  • Finished it all up last night. Took a bit longer than expected since I had some new through hole muxboards made up at oshpark since the SMD mux boards would just not function properly no matter what I tried. Tested every point for continuity, replaced ICs and made sure there were 0 bad solder joints/bridges/etc and they still would only work 70% of the time. These new Muxboards worked the first time, and I have had no accent issues since. Also installed the secondary noise source v3 by michigan synthworks for the handclap.

    The Chia Shin knobs are fantastic, if you are going to build a kit, definitely snag a set from KlangGenerator.

  • hey pretty cool, are those boards shared on oshpark? lot of folks here could use them...
