NOTE TO StarTekh: Yes, I have the "QuickStart Guide". While the guide contains interesting information about the MDP26 device, there is nothing there that explains installation or making SONAR work. I also have all the manuals provided by Vysex and a rather odd one-page printout from Akai talking about the MPK88 keyboard controller. (Yes, it has keys and pads and is similar, but...)
NOTE TO LunaTech: As a beginning answer to the question posed by LunaTech (lol), let's say I do the following: (1) Plug in MPD26 to USB port. (2) Select MDP26 preset named "SONAR" and "push to enter". (3) Launch Vyzex application on PC and notice the error message: "Can't open MIDI Out Port Game Controller 1. Driver may already be in use." (4) Then I get a Vyzex screen with: Receiving: Akai Professional MDP26 Edit Buffer MIDI IN Port: [Akai MPD26] MIDI OUT Port: [Akai MPD 26] Comm Channel: 0 Bytes Received: 0
...and the dialog never does anything else and never receives data.
So, I "Cancel All" and finally see the full Vyzex MPD26 editor dialog and then don't know... a) ...if anything is wrong - like Midi Port 1 or no data --or-- b) ...what to do next.
Of course, you may wonder why I even launch Vyzex. I don't have a good reason, but the error seems important.
So, at this point, we haven't even discussed starting SONAR and creating some kind of generic device and actually talking to the MPD26.
Well, this is just the beginning. Tomorrow I'll start typing up an error-by-error list of problems when I try to edit SONAR preferences and "connect" to the MPD26.
Meanwhile, I would like again suggest the possibility of PC-to-PC connect so that you can see immediately what the errors are. The direct experience on my PC would probably save a lot of time. And of course I'll pay for it.
[P.S. I don't understand how to answer a post directly, so this is just a sort of general post hoping that you see it.
