For a while now I have been trying without success to get three external sequencers to sync with Reaper.
Korg EA-1, Korg Es-1 and Roland M-303
Using midi options and options.
Whilst It works to a degree it isn’t ideal – timing is off and looping is out of the question.
If you press play from the start of a project they will all fire along nicely – record it though and they will be out by what I can tell is a 32nd.
So I looked around and found this thread.
In the first post the poster mbncp has a link in his signature to MidiClock.txt
You will need to download this to your reaper plugin folder and change the extension from txt to js.
A different method would be to open the txt file and copy all the txt and do the following.
Open FX – ‘Add’ right click and ‘Create new JS FX’
Name it something – probably best to call it ‘MidiClock’
The following screen will open – this is where we will post our code.
Open your ‘MidiClock.txt’ file and copy all the text.
Now go back to Reaper and the opened FX.
Select all of the code and paste the new code from the txt file.
You should now see this.
I’m not sure but I think you need to click ‘Full recompile/reset’ to enable save.
Either way if you close the ‘Edit’ window it will ask you to save what you have done.
I then removed the finished plugin and then added it back to get it to launch as it is below.
The next thing to do is make sure your midi device is set to send SPP out.
After that we need to set up a track to send the next fx to our external device.
On the track containing your ‘new’ midi clock.js
Click the ‘io’ button
Look at the ‘MIDI Hardware Output’ section
We need to change this.
The ‘Output’ should match the midi device that your external device is connected to.
In my case the Korg ES-1 is connected to my Focusrite Pro1010
Now here is the important bit, midi in on the ES-1 is set by default to channel 11 – if this is not changed here to match midi sync will not work.
Now with this setup I have perfect syncing and I can loop sync as well.
Not only that, if I connect my EA-1 via midi thru and then my Roland MC-303 to the midi thru of the EA-1 I get all three in perfect sync.
