Midi-syncing a Roland TR-707 with a TB-3 

If I understand your question you want the TD3 to play a pattern when the 707 starts? Sounds like you're trying to do the opposite of what I do in this video. In the video the TB-3 is the Master Clock source - it controls the tempo of the 707 and tells the 707 when to start and stop. I got rid of my 707 and I don't have a TD3 but maybe try this: Put 707 in Track Play mode (under Play press Track?); Then hold down Shift and press Sync Mode until the display shows a tempo number (example: 120), not S-d, S-t, or S-n. That seems to make the 707 the Master - it will set the tempo and tell connected devices when to start/stop (if I'm reading the manual correctly). I found the next steps on a Sweetwater article about the TD3: Set the TD-3’s clock source to its connection type. Connect a MIDI OUT (cable) from another device (707) to the TD-3’s MIDI IN. Manually adjust the clock source (of the TD-3) by pressing the BACK and WRITE/NEXT buttons at the same time. (You want to choose 2-MIDI/DIN): Clock Source: Press Selector 1 (INT/TD-3), 2 (MIDI/DIN), 3 (USB/COMPUTER), or 4 (TRIG/SYNC IN). Hit play on the master clock device (clock source - in this case the 707). The TD-3 will follow the Play command and tempo. The TEMPO knob on the TD-3 will not work (set the tempo on the 707), and you can use the pattern and Pattern buttons to create an arrangement. To get the TD-3 back to normal operation follow the above to choose Clock Source 1 (INT/TD-3). Then the TD-3 will be a master device again.

@CorduroyCam I'm starting to think the midi out port is broken 😐 . I manged to get TD3 to trigger 707 but not in the way I wanted , I'll try and see if din sync will work tomorrow . I'm having a break from it , I went from feeling super happy because I had an amazing 303 clone to unbelievably disappointed because I couldn't sync them . Thanks for your ultra helpful reply 👍🏻 , it was super kind of you 😀 Have an amazing weekend

@@edwallace3704 Also maybe try another midi cable? I recently drove myself crazy trying to get some devices to sync and it turned out the midi cable was faulty. Good luck.

@CorduroyCam I changed the midi cable , I want the 707 to be able to control start stop of Td3 and tempo . I manged to get td3 to trigger 707 but it was triggering td3 pattern with 707 drum sounds so sounded weird . The out cable on 707 looks damaged so I'm thinking maybe it's broken , I did take it to a guy a couple of weeks back and he tested it and said it was fine 🙂 , it's ultra frustrating have 2 amazing machines and not being able to get them working together

@CorduroyCam I'm gonna have a coffee and try this now , I'd have a fee beers when I messaged last night and forget about this reply lol

Hi, I think you can do that but you'd have to check the TR-707 manual. It probably sends midi-out on channel 10. You'd have to figure out which "notes" each drum part of the TR-707 plays/triggers, and then set up your MPC2000 samples to be triggered by those notes. You may also have to set the TR-707 to send out the midi (i.e. act as the master device). Don't quote me though!
