I was wondering, before i spend a lot of time building a lsdjmc2, if it is possible to even sync lsdj to a sp-404. I don't know a whole lot about midi, but the 404 only has a midi input, no outs. Can LSDJ (with a lsdjmc2) work with that just to tempo sync?

You could build this:

Then lsdj can be master and the 404 can be slave.

hahah i had the same fail wiz mc 2 -- //
++ built arduino boy too but it just dont work right : (

ok, i feel like im in a liiiiittle over my head. arduino looks like the way to go for what im wanting to do, but which arduino board do i use? will that hand-drawn schematic on the google page work with any cheaper board i get? is there anything that i can cut out from that to make it a little simpler for what im wanting to do? i literally JUST want a midi output to sync a drum machine/other stuff later, nothing else really.

Forgive me if I'm skimming that wrong, but doesn't that circuit make lsdj the slave to a midi input?

• Press start on your MIDI clock-generating device, LSDJ will follow.
• As you change tempo on your MIDI clock-generating device, LSDJ will follow.
• If you press stop on your MIDI clock-generating device, LSDJ will stop. However, to start again from the same position in the LSDJ song, you will need to manually select it and press start before pressing play on the MIDI clock-generating device.
i can build you one no problem, just built one for a fellow cm member =]

That's the issue though, I have nothing that generates a midi clock right now.

matt's mind
your computer can do this. through your DAW for example...
all you'd need would be a simple cheap MIDI/USB cable just to have the clock.
you can also get standalone clock generating boxes, but they can cost a bit (its a bit of overkill or your purpose). (MOTU made a unit back in the day called the 'MIDI Timepiece' that has a bunch of outputs you can set clocks to. but, you've got to manually control them now since the software is wayyyyyyy outdated (and the hardware hookups too), but they are old and outdated and like... $10 on ebay. i've got one of them for clock generation solely in fact... (use my computer for that now though).
i would imagine that there is a MIDI program you can run that only generates a clock, so you wouldn't have to run your DAW to get this. i don't know one though, but its such a simple function i'm sure something out there exists and for free more-than-likely.
you can also do this with MAX/MSP, and with a little searching you'll find a MIDI signal genrating app. max/msp is some good stuff, and the runtime version is free. and it isn't CPU intensive for something like this 
that is, if you want to generate the clock from something else to sync all your other things to, rather than have one of your devices as the master as suggested above.
you may also want to just commit and get a MIDI in/out box. I highly suggest the more modern MOTU products.
hope that helps some!

this is enough for LSDJ master sync:
You have to change the code slightly so that the LSDJ MASTER mode is fixed.
And I think you can use any arduino clone.

kitsch: yeah, i know my computer can do it but i really dont like using my computer for music stuff, as unreasonable as that sounds lol
that schematic is exactly what i was looking for, awesome! will this work for the arduino?: http://shop.moderndevice.com/products/rbbb-kit

Yes.

last (probably) stupid question: if i were to use the rbbb kit, how do i reprogram the code on the arduino? can you do it over midi?

nope. you need a programmer. i just ordered a 28 pin dip programer =] pretty psyched

you don't really need a programmer - RBBB has headers for FTDI programming cable. something like this:

Or find someone who can do this for you. Or find someone with Arduino Duemilanove or Uno to get the code on your chip.

The cheap arduino clones usually don't supply a way to program the chip with USB, what we call TTL to USB, on the official Arduino it's built in, hence a USB port. For products like the one you linked to, you need a FTDI to USB cable or something simular. Which can cost $20 or so, making the clone not so cheap in the long run. Unless you desire the form factor it's worth the extra $15 to get a Arduino Uno.
