Once connected to the computer you have to open your Daw and find the menu to activate the mixer via midi. Check the user manual of your Daw. Also you might have to do some midi mapping to set up the controls.

MIDI(Musical Instrument Digital Interface) is a standard data transfer system used exclusively for instrumentation. A side from amps 7 recording equipment many PCs, laptop & TVs have MIDI access built into them. If they can interface with a UBS connection it is more likely the exception rather than the standard. Below is a link to the users manual for your keyboard. Start reading on page 39.

You need to load software on your computer that contains midi sounds - sampletank, Reaktor, etc. Make sure everything is set to Midi channel 1.

Use LMMS software on PC. You will need a MIDI to USB cable which you can get on eBay.

The manual can be found at:

You will need MIDI cable - widely available from good musical instrument (keyboard) stores and on the internet

ALWAYS to answer your question, refer to the "MIDI IMPLEMENTATION CHART" for your MIDI instrument.

This chart can be found USUALLY near the end of your user's manual.

This chart, among other things, will tell what can be transmitted and received by the MIDI device.

Refering to the chart for your DX21 it shows that the DX21 can both receive and transmit program changes.

If you don't have a user manual, download one here:

I may be able to help.  I am a longtime Mac and Tascam control surface user.  I am currently running a MacBook Core 2 Duo 2.0GHz running OS 10.5.6 with a Tascam FW-1884 audio interface/mixer/control surface connected.

Setup is fairly easy in the Mac OS.  Here are the steps I'd follow:

NOTE: Before beginning the following process make sure that ALL of your MIDI gear is connected.

- Tascam connected to USB port of computer
- MIDI Keyboard "OUT" connected to Tascam "IN"
- Roland "IN" connected to Tascam "OUT"

1) Open your "Applications" folder.
2) Open the "Utilities" folder.
3) Double-click on "Audio MIDI Setup."
4) At the top of the window select "MIDI Devices"
5) In the pull-down menu on the left select "New Configuration."
6) Title your configuration and press "OK"
7) If your gear has been detected automatically their names and icons should appear in the main window.  If so, skip down to step 12
8) Click on the "Add Device" button
9) Double-click on the "new external device" button that has now been created.
10) Select your device's manufacturer and model (i.e. Roland, JV-1010).
11) Adjust any other settings appropriate to your setup.

[In the main window there should be a Tascam US-224 button.  On it there should be one pair of arrows that indicate the MIDI In and MIDI Out ports of the device.]

12) Click (and hold) on the MIDI Out arrow of the US-224 button.
13) Drag the "cord" and attach it to the MIDI In of the Roland JV-1010 button.
13) Click (and hold) on the MIDI In arrow of the US-224 button.
14) Drag the "cord" and attach it to the MIDI Out of the "keyboard" button.

This should get you setup from a Mac OS/Device routing perspective.  For the appropriate US-224 Control Panel settings refer to the User Manual.
