  • DIY blackbox Sequence Launcher

    I built a simple 4x4 pad sequence and sample launcher for the blackbox, here's a link to the code and a mini tutorial on how to build one if you're interested. It's made with a NeoTrellis driver board, Feather M4 microcontroller, acryclic case, running CircuitPython.

    This version involves a tiny bit of soldering, but I plan to also make a version for the NeoTrellis M4 which is 8x4 and a self-contained unit with no wiring necessary.

    So well done! And thank you for the mini tutorial.

      Very welcome. I just got it working on the 8x4 grid NeoTrellis M4, with the left 16 for sample pads and the right 16 for sequence triggers. I'll optimize things a bit and post the code soon.

    Great! Would be so cool, if the blackbox would send midi notes on activating/deactivating pads/sequences to make the controllers lights could respond and stay always in sync.
    Some commercial controllers support that too, like novation launchpad.

      Totally agree -- I'm going to chat with Aaron and Christine about this to see what's possible.

    I've added code and instructions for making a 32 pad NeoTrellis M4 version that has 16 sample pads and 16 sequence launchers available at the same time.

      Hello,

      Thank you for sharing this.

      I am very interested in this Neotrellis controller M4, but i have really no experiences in using Arduino / codes and so on...

      However the link to the code and a mini tutorial seems very detailed and helpful, nothing complicated at first sight but do you think it is afordable for such a newbie as i am ?

      Thank your for this shareonce again by the way.

        Hi EaSir, very welcome. I created this project using CircuitPython, which I think is a bit easier to use at first than Arduino (you can code the NeoTrellis M4 with either).
        Here's a good tutorial for getting started.

          NeoTrellis well received / Mounted and configured... that was such a easy step with your tutorial and CircuitPython... Very nice project and device and very happy with a very limited budget that is perfect.

          One question by the way, i've noticed a drop in the sample volume level when i play any samples with the neo trellis. With the BB touchscreen the sound is at normal level. it looks like there is a volume limitation with the contrĂ´ler... any clue about this?

            That's great to hear EaSir_11 thanks for letting me know. Sorry about the output level thing -- I bet I specified 64 as the velocity in the NoteOn messages. It should be 127 to be full volume. I'll update the repo. Good catch!

              Updated both variants to 127 velocity.
