    This is my first time attempting to compile with Magma, so I apologize if this is a simple question, but I haven’t been able to find my exact problem brought up anywhere else. So, here it goes:

     

    When attempting to compile in Magma, I get a HUGE list of these kind of errors:

     

    ERROR: MIDI Compiler: (PART DRUMS): Difficulty expert: Chord gems don’t end simultaneously at [29]

    ERROR: MIDI Compiler: (PART DRUMS): Double note-off 98, [29]

    ERROR: MIDI Compiler: (PART DRUMS): Difficulty expert: Chord gems don’t end simultaneously at [29]

    ERROR: MIDI Compiler: (PART DRUMS): Double note-off 98, [29]

    ERROR: MIDI Compiler: (PART DRUMS): Difficulty expert: Chord gems don’t end simultaneously at [30]

     

    I went to these parts of the MIDI, and some of them aren’t chords at all, but single notes. They are completely quantized (I zoomed WAY in) and all chords line up perfectly. I don’t know why it’s trying to render drum notes as chords, either. All my drum hits are 1/16th notes. What am I doing wrong?

      They’re not quantized properly and they may be either be 0 in legth or of different length between them. Requantize with position and length and try again.

      #409700

      I tried quantizing every note – still getting the same errors. I tried running it through a MIDI cleaner and that didn’t help either. These ones are the most confusing:

       

      ERROR: MIDI Compiler: (PART DRUMS): Difficulty easy: Chord gems don’t end simultaneously at [3]

      ERROR: MIDI Compiler: (PART DRUMS): Double note-off 64, [3]

      ERROR: MIDI Compiler: (PART DRUMS): Difficulty medium: Chord gems don’t end simultaneously at [3]

      ERROR: MIDI Compiler: (PART DRUMS): Double note-off 76, [3]

      ERROR: MIDI Compiler: (PART DRUMS): Difficulty hard: Chord gems don’t end simultaneously at [3]

      ERROR: MIDI Compiler: (PART DRUMS): Double note-off 88, [3]

      ERROR: MIDI Compiler: (PART DRUMS): Difficulty easy: Chord gems don’t end simultaneously at [3]

      ERROR: MIDI Compiler: (PART DRUMS): Double note-off 64, [3]

      ERROR: MIDI Compiler: (PART DRUMS): Difficulty medium: Chord gems don’t end simultaneously at [3]

      ERROR: MIDI Compiler: (PART DRUMS): Double note-off 76, [3]

      ERROR: MIDI Compiler: (PART DRUMS): Difficulty hard: Chord gems don’t end simultaneously at [3]

      ERROR: MIDI Compiler: (PART DRUMS): Double note-off 88, [3]

       

      All these errors correspond to these three notes in the chart:

      I have quantized those notes in every way possible and I still get the errors. I even tried deleting and re-adding each of these three notes. I don’t know why it’s considering everything a chord note, and why a single note is having problems “ending simultaneously.” I have tried compiling with 1/16 length notes and 1/32 length notes. It almost seems like it’s expecting the chords to end halfway through, but this is how I see simultaneous hits authored in every case. Any ideas?

        Upload your Reaper+Magma project

        I never found exactly what caused the problem, but Farottone helped me find a fix. I’ll post it here in case someone else has this problem.

         

        Somehow the MIDI playback speed of the Drums track got messed up, so I had to copy all the notes over to a new project created from the RB3 template. COPYING OVER THE ENTIRE MIDI TRACK WILL NOT WORK – THE ISSUE FOLLOWS THE TRACK. You don’t have to redo all your work, however. Just start with a brand new blank drums track from the Reaper template. Open up your old track in the MIDI editor and ctrl-A to select all the notes (make sure you get your drum events too!). Paste those into the blank drums track.

         

        Rather than copy all the other tracks over to the new template, I just did the above steps to copy the drum notes into a non-screwed up track in a new project, then I deleted the entire drums channel from my original project and moved the new one to the old one (take the entire MIDI track this time). Hope that helps!

        #410156

        So you basically fired up a new project, and just copy-pasted the notes from the previous project to the blank slate.

         

        So I’m assuming the tempo map got transferred somewhere in the process if you did it this way?

        #410161

        The song I was working on was thankfully a single tempo, so that was easy to copy over too.
