Strange problem with the following setup showing the wrong notes on the screen although playing the right note.

Windows XP Pro +SP1
Creamware Luna II sound card
Yamaha CS1x keyboard

As a sample of the problem: using a program with an on-screen piano keyboard, in this case Voyetra's TeachMe Piano. Playing middle C on the Yamaha keyboard is displayed as B, although the sound played is correct (C). If C sharp is played, it is displayed as middle C. I checked the MIDI mapping with an app called MIDI monitor and sure enough playing middle C is interpreted as B4 corresponding to the note displayed. Playing C sharp is interpreted as C5 (middle C) corresponding to the note displayed.

In the Audio tab of Sounds and Audio Devices Properties of Xp, I tried all the options available for the default device for MIDI music playback, which are: CreamWare MIDI In/Out 1 and Microsoft GS Wavetable SW synth, with and without the "use only default devices" option.

Program's settings are:
MIDI input device > CreamWare MIDI In/Out 1
MIDI output device > CreamWare MIDI In/Out 1
Patch Map > General MIDI (no other option available)

Sounds to me (no pun intended) that the error maybe between the Luna II soundcard and XP's MIDI mapper. ¿¿¿ Any ideas ??? :confused:
 
Sometimes this can be sample-rate related, but usually if it shows wrong it also plays wrong. Are you monitoring the actual output of the keyboard or were you monitoring the signal post-software. Are you using the Yamaha keyboard as the reference to wheter the right notes are being played. If the keyboard itself is transposed it may affect the Yamaha sound engine only, but not indicate correctly on the software, which is recieving Midi note information (Which probably won't display the transposition within the Yamaha). Check your tuning against another instrument or tuner (Not a soft-synth, something that is completely independent of this system). Check to see if the Yamaha is Transposed, and likewise if you were monitoring MIDI post-software (which will include control software for the LunaII as well as Voyetra) check that there are no Transposition settings active in your software. If you are mapping through any software other than XP natively (i.e. MIDI Ox), make sure it is not changing the data (compare Input and Output monitors). I have never seen XP itself alter the signal this way. And if everything checks out to be in-tune right, and you still can't figure it out, Ignore the onscreen keyboard. As long as everything works, who cares what the computer thinks.

DOH! :p

Back then, I ever forgot to reset the +4 transpose on stage, and I took the intro. My singer staring at me as he couldn't reach the high notes. Then the band was coming all of the sudden in the middle of the song.... What a youth... :p :D

They should invent transpose beeper alarm somehow... :D
