Hello,

Can I use these caps too?

The ones described in the BOM are out of stock everywhere…
Sorry if it’s a noob question :slight_smile:

Hi!

Is it possible to constrain the CC values sent? For instance, with the Octratrack, I’d rather the faders didn’t go all the way to 127 when controlling volume. I can see some settings in config.h, but it seems like they’d affect sent CV as well?

Thanks!

As far as I know, the CV won’t be affected. Try to modify the fader maxvalue in config.h

CV is never affected by code; it’s just raw voltage divided by the pot. It will always be 0-5V.

You can adjust the scaling values there, or, frankly, alter the mapping code in the main .ino file.

Thanks for the tip! I used

temp = map(temp, MINFADER, MAXFADER, 0, 13500);

to constrain the CC’s to max out at 104 – I guess this isn’t doable by fader, just for the entire set of faders?

I mean, it totally is possible to do it by fader, but not in a single line of configuration. You’d need to write some more code. You’d basically make an array of mappings, of the size [16][2] - ie, 16 max/min pairs. And then you look up the right mapping for each fader.

It’s just a bit more of an exercise for the reader.

Thanks! I’m learning, really appreciate it.

I finally got some new solder in and reflowed a bunch of the joints you pointed out, and flipped the diodes around and… it all works!

The IPA is liquid magic. That and a toothbrush cleaned the shit out of the board, almost to the point that there was a thin layer of flux residue on everything. I had to keep cleaning the whole thing off, then more scrubbing, then more wiping down, to get the coat of shmear off the whole thing.

Thanks so much for your helps in this thread! (@okyeron, @Nordseele)

I finally got around to trying this, specifically using the 16n as a bridge to send MIDI to SC.CV and SC.TR on the ER-301 and it totally works. Having the ER-301 working with no cables plugged into it other than for audio output is :exploding_head:

I also just noticed that @infovore has posted an update to 1.33 of the master whereas @scanner_darkly’s branch is from 1.31. Or at least that’s how my lowly git understanding is interpreting things. Am I missing out on anything in particular by using an older branch? Everything seems to be working at the moment but the 1.33 update sounds like it’s specifically geared to MIDI and leader mode which is exactly what I’m now playing with. Any chance of them being merged? Also, bear with me, my understanding of git is minimal at best.

Thanks as always!

I used naphtha for while and it was magic for cleaning boards without that residue. Unfortunately it’s basically liquid cancer, so when my can ran out I didn’t replace it. Isopropyl is good enough.

iiuc the issue fixed in 1.33 doesn’t affect everybody, so that would explain why it’s working for you. either way i should rebase my branch now that the fix has been merged. i’ll try to do it today - it’d be great if you could test it as i don’t have the time to test it properly.

Would be happy to, let me know when it’s up

ended up doing a manual rebase as the conflicts were too confusing, so it’s a different branch now: https://github.com/scanner-darkly/16n/tree/ttmidi2

not tested at all but i did confirm it builds without errors.

Hi builders. I finished assembling everything yesterday evening - but I am getting nothing from the Teensy. No blink, no lights at all. No teensyduino connection, nothing.
Have I blown the teensy somehow? Maybe something else is wrong? What would be a good first step to debug?

Thanks

Usual question: is the USB micro cable you are using a real data cable, or just a charging cable that doesn’t have data lines? Some cables from chargers or battery packs are the latter.
