Replace R365 value by 1K and R314 value by 4K7 to increase Midi signal should solve this issue
only for rev.1.00 pcb: (not for 1.01, 1.02)
c163 to the new value mentioned 0.47 uf fixed with 10NF see Bugs
Snare Drum
Q43, Q46, Q49

from Nava Forum: http://www.e-licktronic.com/forum/viewtopic.php?f=24&t=970&start=20 Q43, Q46 and Q49 are in the wrong way. This is a mistake. When we designed Nava SD PCBs, we placed this transistor to act like switches to generate SD envelopes. We had some sound test and it was okay for us but this transistors should act like amplifier. To solve this issue you need to bend transistors pin 1 and 2 to swap their position in the pad. |

summary: Afaik the first pcb (v1.0 ) has 3 bugs, all of them are highlighted in red in the build guide and are easy to fix. |
open: check in BD C8 for closer BD Decay (the Nava Decay is bigger as the original)
MODIFICATION:
my version was build with addon second Noise source for fixing the loudness balance with snare and handclap
