I2C destination setup options

[Zosimos]

Any good instructions or tutorials on how to send triggers and cv from nerdseq to er301, or anything else? I literally can't get anything out of it and feel stuck, i2c is not really user friendly. thanks

You've got to make sure of a few things. Ill be try to be thorough, sorry if that's annoying.  

1.  Make sure you've connected it right. Depending on which revision of the ER-301 you have, you might need to do a bit of soldering. 
    - If you have Rev7, See this: https://docs.orthogonaldevices.com/er-30...7/i2c.html

2. In the Nseq. There is a page under PROJECT called "Midi / i2c Setup"
- Under I2C Settings: Make sure that whichever port (A or B) you've set the ER-301 up with is set to "Out"
- I2C (A/B) MODE : OUT

3. Set up a track for i2c/multi, and set up a some of the Destinations to (A-B) SC.CVGA - A:31 - P1 (for example)

4. Check in your ER-301's Admin Tab for a section called "Package Manager".
- Check to see if you have "teletype" installed. If so go to its config
-Verify that it is enabled and that the Address is set to 0x31. You can use 32 or 33 as well, just make sure to set that up with your Nseq too. 

5. Make a quick instrument like a varispeed, load up a sample, and put a "SC.CV" Unit into the V/oct And a "SC.TR" into the gate.
- Be sure the Ports match the port setup in the Nseq (the P1).
-SC.CVGA will let you use both CV and Gate in one channel, it's very useful. 


Hope this helps! i2c is definitely not user friendly. It's really the engineer's play thing, and for musicians it can be a spider's web.
