MyFirst™ PCB going to Italy for testing...

Interesting! I tried to do the same thing with the low-gain 4player adaptor mod, but never got it to work properly.

Pretty cool!

Am I correct in thinking the DMG-07 multiplayer adaptor thing wouldn't be able to achieve this? If not, how come?

Basically you have to gut it and just connect all the link ports together. Since the communication only goes from one Gameboy to the other 3, nothing goes back. All the processing to do multiple input/output isn't necessary.

This would probably work with an Arduinoboy to tempo sync multiple LSDJs to midi clock or send mGB data to multiple units. Someone correct me if I'm wrong! Also, could you Daisy chain them?

I guess it would work for the clock sync but not midi stuff unless you intended for all of them to play the same thing all at once

Well you could use the mGB mods that change the midi channels, so you could have up to three. Though I'm imagining a giant wall of gameboy drones which would be amazing.

Thanks Catskull!

Coincidentally, I'm trying to work out a way to connect multiple Game Boys to a single arduinoboy so I can control external MIDI gear live with more than one DMG. A related, but different problem...

This would be awesome, one Gameboy could control MIDI channel 1-4 and the other channel 5-8.

However, I think this requires a new LSDJ version. Currently there is no way to sync 2 gameboys while running in MIDI out mode. (Correct  me if I'm wrong anyone - I hope I am smile)

I think you're right Ledfyr. It would be great to be able to send the midi clock (event 1/2 ticks for instance) AND midi notes

Yes these can of course be daisy chained.

Yea but the source midi would still be the fixed channels. Arduinoboy can only send up to max 4 channels, no matter what downstream splitter you have.

If you made an active splitter that could transpose the channels, like the midi solutions devices do, then sure you can control more than four devices BUT STILL ONLY FOUR CHANNELS OF UNIQUE NOTES at a time.

Thats probably never going to happen, but id love to be surprised.From what I understand the dmg serial port cant handle the heavy lifting of note ons AND midi clock

Maybe arduinoboy can be altered to work with LSDJ, using one of if the spare cc commands and something like this:

http://forum.arduino.cc/index.php?PHPSE … #msg118206

So everytime you do an X01, that is one quarter note pulse, and you can sequence downstream pulses. Then you can use a 2nd aboy on a bunch of gameboys that only derive clock from the channel.

You mean, like that: https://github.com/ledfyr/ab-midiout-lite ?

I would also like a kind of reverse-livemap, where lsdj would automatically send its current song position when starting to play a new row

Lsdj master works like  "your reverse map"
https://github.com/trash80/Arduinoboy#l … row-number
Youd have to grab the midi note and convert it to row position in your sequencer app, but its really handy for triggering for example an ableton live scene on live row trigger.


I just mean that arduinoboy is also just generating midi clock like something like this
http://www.disasterareaamps.com/shop/smartclock
And you can turn it on/ change the tempo using the midi command functionality already in LSDJ. Then you dont need to update LSDJ at all.

Does it send a midi note on each row number, while playing ?
I thought it was only sending the first row number when you pressed start...
