Let's keep it simple for this test:

1. Create ONE track in Reaper with some MIDI notes (could be the same NOTE fo rthis test over, and over, and over) (easiest way load a MIDI file and delete ALL but one track - so you can focus on where things are)

2. Now I have Reaper but don’t use it much so there might be a better way but on a few of these:

a. Options -> preferences -> MIDI devices - make sure your UR22 Input and Output are enabled.

b. On the ONE MIDI track, click on the "Route" (it's to the right of the track name/title) and under "Sends" click on "Add new send…" on the same menu on the right hand side, under "MIDI Hardware output" select your UR22.

Again on SAME menu right under where you selected the UR22 as MIDI output lets force (guarantee) the MIDI channel you will send this track on to the UR22 so now pick "Send to Channel 2")

c. lets verify your Digitech, according to page 32 of manual (below) , is set to receive on 2 (or OMNI):

"…
To change the Vocoder MIDI channel(s):

1. Press the Utilities button from any mode. This presents the UTILITIES main menu.Press the soft key corresponding to MIDI. This presents the MIDI Utilities submenu.

2. Press the soft key corresponding to Channel.

3. Press the Right Arrow button.

4. You can select Vocoder voices 2, 3 and 4 using the softkeys below them. Voice 1 follows the system channel and cannot he changed in this screen. The channel settings can be changed with the upper and lower softkeys or the Data Wheel.

Selecting the "off- option by turning the Data Wheel to the right dis¬ables external control of the Vocoder. Selecting the "omni" option causes the Vocoder to respond to notes on any and all MIDI channels.

6. Press the Utilities button again to exit. This returns you to the mode from which you entered."



Now in a quick search of Digitech manual I can't quickly find where you change system channel (usually MIDI channel 1, this is the channel which allows you to send commands, like Program changes, song key, things other than, or in addition to, musical NOTES) that's why I want you to SEND from Reaper on channel 2. Assuming you have a SOUND of some kind (at least one voice) set on Channel 2 in Digitech.

Let's see if this makes sound.
