MIDI Keyboard issue (Mac) - double answers

[Wowo]

I'm using a mac and a midi keyboard through m-aduio fast track pro USB interface. When I try to use my midi keyboard to answer, everything comes two times. Example. I try to answers C, but Earmaster marks C C.

Anyone with a solution?

Hi,
Did you download the latest update (from the HELP menu: "Check for Updates...")?

I'm evaluating the free trial version of EarMaster 6 that I downloaded a couple of days ago and am so close to buying it, but just ran into this same issue where anything I play shows up doubled. I checked for a newer version but I am running the latest one: Build 620PXi (Macbook Pro)... I'm using an E-MU Xmidi 1x1 interface with a Yamaha P-60 electric piano.

Hi, I decided to try downloading the Windows version (build 620PW) to see if it had the same issue, but it works fine under Windows without any of the doubled-input issues I was seeing when using my Mac laptop.

Hi,
I tested it on a MacBook Pro with a class-compliant MIDI keyboard, and I am not getting this double-note input problem that you are describing.

I will try to reproduce the bug with a MIDI keyboard plugged into a MIDI interface later today.

Thanks for investigating this issue!

Your reply reminded me that I have an M-AUDIO Keystation 49e usb keyboard controller, so I got it out to see if using it would avoid the same issue. Unfortunately, when I tried it the notes were all still doubled. Not sure if it makes a difference, but I am on Mac OS 10.7.5.

Here is an example of what it looks like (you can also actually hear the notes being hit twice rapidly in succession as you play them):

Hi, I decided to go ahead and buy a license to EarMaster because it is still worth it even with this glitch, but look forward to this issue being fixed in the future.

Thanks!

I could not reproduce this issue either.
(Mac mini, OS 10.6.8 ) and an edirol master keyboard.

How is the midi input working in other programs?
Do you get double notes there as well?
e.g. garageband.

I tried GarageBand, but didn't have the doubled notes in Garageband. I created a video to illustrate...

I also tried a free app in the App Store called MidiTrail that will visualize midi in data, and it didn't show any doubling.

Could this be at all related?:

i.e. could the controller be sending MIDI on two ports? If this is the case, could EarMaster be configured to only pay attention to one port?

Having the same problem with my iRig Keys. I am able to get around this by routing MIDI through Ableton Live and sending it to the IAC driver.

Hi,
Have you updated your EarMaster 6 installation? A lot of smaller things have been fixed since the first post here, so maybe the problem win't happen with the newest build.
