Hi Tony,
Sorry to hear that you are still experiencing problems attempting to hook up your VM5 to your Roland EM2000.
Here are some answers to your questions:
1. How do I find out the basic midi channel that the Roland transmits over/on?
Typically the basic (universal) midi channel that Roland transmits is channel 1.
Tony, I don't own the Roland EM2000 keyboard but there should be a button on your keyboard that takes you to the midi settings page. To avoid confusing you it might be best if someone else on this board who actually owns an EM2000 to guide you to the specific settings page where you can both set and check the midi transmit channel for arranger chord transmition. I think the midi channel for transmiting "midi chords" should NOT be set to the same midi channel as the basic midi channel (1).
2. How do I find out/ which channel transmits key change data.
Tony, "YOU" set this yourself. Just be sure to choose a midi channel which is not being used already to tranmit note, controller, or any other type of midi data (including the basic midi channel).
3. Does the digitech need to be set to program change...midi notes....or midi chords in order to recieve the key change?
The Digitech MUST be set to "Midi Chords".
Tony, if you are still having troubles, here is the customer service web address of Digitech Corp:
http://www.digitech.com/contact.htm Just fill out the online customer service request form outlining your problem in detail and they should (with luck) be able to help you. Be sure to tell them that you are using the VM5 with a Roland EM2000. You might also try emailing Roland Corp as well.Unfortunately I don't know the web address for Roland Tech Support.
Best of luck,
- Scott
