We are building Nava 909 W/Rom 1.023

Buy/Sell/Trade Yocto, Nava parts, full build unit, build service...
  • Hello.

    I had a NAVA last year. Two things made me sad, so I had to sell it.

    Does version 1.023 address the problem with the High Tom being too loud?

    Does version 1.023 allow the pattern to play to completion before switching to the next? Or does the pattern immediately switch to the next pattern. That drove me crazy.

    Lastly, would you be able to build it for USA power? Or would you rather me buy a voltage converter?

    Thank you,
  • Hello Steve,

    Version 1.023 is better with the high tom.
    We also have fixed the overloaded stereo output problems and noisy output problems.
    The NAVA is now very quiet and has a great balanced stereo output.
    Re the patterns: it switches by the end of the last note normally now.

    The greatest side of the NAVA compared to the Roland TR-909 is its PSU, the PSU is actually an external one,
    this mean you can just buy an 15V/1000Mah DC adapter in the US it will work
    without a hitch

    Here are the latest specification of the firmware

    -No more HH ticks background noise
    -Improved velocity on all instrument
    You should replace C89 and C163 by 10nF (Build manual and Mouser BOM updated) ;)
    -Clear pattern now set minimum velocity that increase velocity response
    -CH Tap Mode bug fixed
    -Improve Slave sync when pattern save/change (Please Keep up to date on improving sync cause we do not have this issue with our Midi interface)

    -Fix OH select Bug

    -Tap Bug fixed
    -Velocity HH can be saved
    -OH Velocity and Total ACC conflict solved
    -Improved BD, SD and HC velocity response
    -RX Midi channel issue solved
    -Buttons functions improved
    -Sync test in slave mode with a TR505 and with Ableton and Midi interface.
    Sync with hardware is perfect but Nava loose some clock signal when sync with a software thru a Midi interface.
    Replace R365 value by 1K and R314 value by 4K7 to increase Midi signal should solve this issue

    -Fixed CH and OH bug in MIDI play
    -Add a config page that allow you to set the sequencer pattern change SYNC or FREE: -Push Tempo button twice while holding SHIFT button to access to the second config page. Use the encoder to select "pCH" (pattern change) SYN => SYNC or FRE => FREE. push the enter button to store new sequencer setup

    -Fixed Middle Tom low volume
    -Now respond to Midi note ON velocity 0 message as a Midi note OFF message

    -Fixed Total Accent issue on crash and ride instruments

    -Original version

    Best regards

  • Perfect, but not DC power adapter, but AC!!

  • Does anyone know where you can get a picture of the 1.023 board, I can't find where C163 is or C89, the interactive BOM is wrong.
