OK - another MIDI problem !!

• Mar 10, 2010 - 17:13

OK I give up !!! I've read all the other MIDI problem threads and tried all the advice given, but I still can't input notes from my MIDI keyboard. Sorry to start yet another MIDI problem thread, but I couldn't see a way to tack onto any of the others.

My setup is Win XP+SP3 with Lexicon Omega audio/midi interface and I use a simple roller piano for note input only, nothing else, which works fine with my other notation software, (which I am trying to abandon in favour of MuseScore), see pic attached. The roller piano has only a MIDI out port which I've connected to the Omega's MIDI IN port, of course. According the the Omega's wiring diagram, its MIDI IN is not processed at all but goes directly to the Omega's USB output and therefore directly to the computer.

In the MuseScore IO window, see screen shot attached, the Omega's ASIO drivers are selected which works fine for everything else. I've tried everything I can think of to get note entry working from the roller piano, but failed miserably so far.

Any suggestions would be greatly appreciated.

Nice setup!
MuseScore 0.9.5 on windows requires that your MIDI IN is the first MIDI device. It's quite hard to determine if it's true sometimes. You may have a virtual MIDI device or another driver installed?

To tackle this issue, the upcoming 0.9.6 will have a device selector in Preferences->I/O. You can [[nodetitle:Download|download]] a beta or a nightly and try to select your MIDI in from the preferences panel.

Ah I see, (I think). It might be that the Omega is not appearing to MuseScore as the first MIDI device. Would it be worth buying a 5 pin DIN to USB cable and putting the roller piano directlty into a spare USB port on the computer? Actually, on second thoughts, I can live without roller piano note input until 0.9.6 so I think I'll leave well alone until then.

Thanks for a truly excellent application, and for your friendly and helpful advice.

OK I downloaded 0.9.6 and selected Lexicon MIDI in the new MIDI device field in the IO window

Here's what happens when I try to input MIDI from my roller piano into 0.9.6:

When I select the first rest, press N to enter note entry mode and press a key on the roller piano I get screen shot ss1 attached.

If I close that window, enter a note from the computer keyboard or mouse the note appears correctly.

If I then enter more notes using the roller piano the notes appear on the stave OK, but all in the same place. Screen shot ss2 attached shows that all the notes enetered from the roller piano have attached themseves to the original note enterd from the computer keyboard instead of progressing along the measures.

I'm not looking for a solution to this. I just thought you guys working on 0.9.6 might like to know that this is what happens.

By the way 0.9.6 loads like lightening compared to 0.9.5................and it hasn't crashed yet !!!

Keep up the brilliant work.

ss1) you have to tell the program where you want to insert the notes by selecting the rest or note where you want to begin.
ss2) real time note entry isn't available in MuseScore, so select location, duration, and enter a chord, select another location, and duration and enter another chord.... etc. Since MIDI is a serial interface, no two notes can be started at exactly the same time, therefore, notes entered one after another are assumed to be part of a chord. (just my guess).

OK Thanks for the response.........

That's exactly what I do, namely, select a rest, press N and enter from the roller piano. That's when I get the 'no note selected' message, so it definitely won't enter a note from the MIDI input onto a selected REST.

As previously explained, where a note has already been placed on the stave by the computer keyboard or mouse it does enter notes from the roller piano at the same location as the note selected. In the attached screen shot I have enetered a note on the first quarter rest with the mouse, and have then added a chorded note from the roller piano to that note. I have then selected the next quarter rest in the measure and tried to enter a note from the roller piano, only to get the 'no note' message again.

So it appears that MIDI input in 0.9.6 is currently restricted to entering only chorded notes on a note already entered by other means and selected as the location for note input. I just assumed that MIDI input would behave as it does with other notation software that I've used over the years, from the cheap and cheerful to the industry standards, and place notes and chords sequentially on the stave in exactly the same way as keyboard or mouse entry does.

But if that's the way MIDI input is going to be implemented in MuseScore, then that's OK by me. It's a small price to pay for an otherwise excellent application. I'm just trying to help really.

Hello again David. Yes, I'm using revision 2811. How strange. I'm sure that I'm not doing anything silly here. I just plug in my little roller piano keyboard, as you see in the picture I posted earlier, enable the MIDI input and that's what I get, namely, the ability to enter only chorded notes and not sequential notes. What on earth can be going on with my 0.9.6 I wonder. All I can do is see if the next revision makes any difference I guess.
