The resistor does not go to the teensy, nor should pin3. Resistor just goes between gameboy pin 3 and gameboy ground. Value shouldn't matter too terribly much. You can even completely GND the pin with no resister if you want. Just know that if you use no resister, it will prolly make things like arduinoboy not work, because they use pin 3 for data input.

I used a 2.2KΩ cause it was just what I had, but you can use a 100KΩ, 47kΩ, 22KΩ, 2.2KΩ , or anything you have really. Just solder this at pin 3 of the port and to pin 6 of the link port. (or any other GND point on the pcb really.)

Quick analogy of what a pulldown resistor does: Electricity always wants to flow. It is more work to go through a resistor, but if it is the only route it will do it. If there is more than one connection it will take the easiest route it can (i.e. the path with the least resistance). When nothing is in the link port the only route for the electricity to go is through the resistor to ground. but when you feed a signal to it, it will ignore that path to ground (for the most part) and only worry about the signal coming in.

I'm by no means an expert, so I should not be viewed as an authority on the subject. This is just what I've come to understand about resisters when trying to work it out myself.

I'm just going to leave this here

thanks for your reply! care to elaborate?

Which resistor value?

So GND  on the teensy to link port pin 6 (GND)

Pin 0 on the teensy to link port pin  5 (SC)

And for the fix it will be Pin 1 on the teensy to link port pin 3 (SI)  adding a resistor in between?

thanks in advance for your reply!

Sorry for the obvious questions, I'm a noob at teensy.

Getting a DMG to sync lsdj to midi is an easy fix... Put a pulldown resistor on pin 3 of DMG link port. done.

I have this problem. Followed the little-scale blog instructions very carefully. The teensy board LED goes perfect with the Ableton clock,... but on the the LSDJ side is all weird. I'm currently running ableton on a macbookpro with lsdj 3.9.9 having the same exact problem that others have (tweaking the midi out options while playing, sometimes it starts sometimes not).

What I can possible be doing wrong? I just need sync with ableton midi clock.

Thanks in advance for your answer!

220 ohms maybe?

I got tired of waiting until I could order a tri-wing and just used a tiny eyeglass-repair-sized flathead screwdriver (it actually came with my soldering iron toolbox kit) and stuck it in one of the knotches. Worked pretty well for me.

bump...

Bump for the resistor value for Nanoloop 2.x

This works for me too! Ultimately I'd like to find a less finicky way to do this, but this method works pretty consistently. I just need that tri-wing >_>

Mine works for me every time now. All I have to do is change it from master to midi then immediately start LSDJ while still in the menu screen and then start Ableton. Even syncing two game boys like this is working perfectly.

Ack, double posting but here's something: http://little-scale.blogspot.com/2011/0 … -beat.html

Apparently the original hex file doesn't have support for MIDI beat clock signals, so synchronization is going to be weird unless you're using the Teensyduino code, which you're using the Teensyduino plugin for the Arduino IDE to load to the board. The Teensyduino code has support for beat clock stuff, so that's promising! I lack a tri-wing screwdriver, however, so my experimenting with the board is going to be delayed until I can find one so I can hit that damn button to upload the sketch

I've been working on this a little but I haven't been able to get this to work with any consistency (I actually have katsumbhong's boards with me now >_>).

Loading up Ableton with a blank MIDI clip gets the board to sync just fine and I can tell using the LED on the board itself. The problem is when I'm trying to hook up a DMG with LSDJ to it -- I set it to MIDI mode, hit start so that the DMG is waiting, and then hit play on Ableton, but nothing happens

The only time I've gotten it to sync at all is when I'm messing with the MIDI Sync settings in Ableton. With the board set to an output, all three settings (track, sync, remote) are turned on. Somehow, keeping the sync turned on and turning the track setting on and off repeatedly will randomly start the Gameboy, which is totally weird and makes me think that I'm somehow sending the wrong MIDI messages, but I'm not sure since the board itself seems to be synchronized.

I'd like to get this figured out for a theater project I'm helping out with, so...yeah! Help, plz & thx

EDIT: I'm on Live 8 and LSDJ v. 4.0.5 if that means anything, but it probably doesn't...maybe?

Little update on my end here.
If I switch it out of midi then back to midi, immediately start LSDJ then start Ableton it will sync 9 out of 10 times.
SO ODD.

Yeah, I've gotten it to work without any trouble in Qtractor and FL Studio.
Sonik has Ableton on his macbook, I'll try and sync my GB on there next time I'm at his house.
