The notes/rests appearing in Gray color is a matter of Voice Select in Main Tool Box.

Here is how Voice Select works.

  • Tap V1 to switch editing voice (V2 - V3 - V4, back to V1 and rotates)
  • Selected voice appears in Black, while other voices appear in Gray.
  • In Multi-Voice bars, all V1 & V3 notes appear as Up Stem, while V2 & V4 appear as Down Stem.
    (The relationship of voice and its stem direction can't be changed.)
  • When you open a song, it always starts from V1, which means all Non-V1 voices appear in Gray.

Just to let you know, you can reassign Non-V1 to V1 with Copy & Paste

  1. Change the voice to let Non-V1 notes/rests editable.
  2. Copy them all.
  3. Change the Voice to V1
  4. Paste them.

Now you have those notes/rests in two voices,

  1. Change Voice Select back to the voice you just copied.
  2. Select Clear/Delete Bar tool
  3. Select the first and the last Bar
  4. Select "Clear Current Voice"

First of all, this app is not a universal app. iWriteMusic is for iPhone and iWriteMusic Pro is for iPad and they must be purchased separately. Meanwhile, how they actually run on devices might be a little confusing. Here is to explain about it.
Please be advised, what is explained below is by Apple's design, which means, it’s true to any Non-Universal apps, not just to iWriteMusic.

  1. iPhone version (iWriteMusic)

    Although it is made for iPhone, it actually runs on iPad as well, however, the app screen layout won’t be adapted to iPad screen. In other words, it always stays on iPhone screen format. You can expand the app screen, however, it only enlarges it.

  2. iPad version (iWriteMusic Pro)

    Unlike iPhone version, this won’t run on iPhone (Not shown in iPhone’s AppStore).

  3. iPad version becomes Pro since 3.1.0
    Since the end of 2020, Apple started using their own CPU called M1 (aka Apple Silicon) for their Mac products, which makes M1 Macs capable to run iOS apps as if they were made for Mac. This means, both iPhone and iPad versions run on M1 Macs, however, while iPad version adapts its screen to Mac display, iPhone version, again, stick to its iPhone screen format.
    iOS App running on M1 Mac is not true to all apps, but true to iWriteMusic from version 3.1.0. So we renamed iPad version as Pro with the release of that version.
    Clilck here for more about Pro runs on M1 Mac

To attach PDF and/or MIDI, you must open the file first, then

  1. To email MIDI, select Menu in EditorView
  2. To email PDF/JPG, go to PageView, then select Menu.

Emailing from FileListView only attaches iwm files.
Once you closed the data, iWriteMusic deletes any PDF/JPG or MIDI files that might be created while editing.

iWriteMusic adjusts spaces for each lines when it draws pages. Because of this, Some undesired shrinks or expansions may occur. There are several options in Settings (located in top right in PageView) to make adjustments. Number of bars per line and/or Staff Size may be a good start to solve this problem.

First of all, we’re very sorry for such issue. The reason could be various, but please check below first.

< Terminate iWriteMusic and unnecessary apps >

  1. Double click your device Home button.
  2. All the apps kept in the background will appear.
  3. Find iWriteMusic, Press + Hold it, then swipe it to the screen top to terminate it.
  4. Also, please terminate unnecessary apps you found there in the same way.

iOS may not terminate the app properly when it crashed for some reasons, then then the app won’t restart properly unless you do this. Also, keeping too many background apps may cause issues.

< Restart your device >

  1. Press + Hold your device Power switch.
  2. “Slide to Power Off” message will appear.
  3. Do it.
  4. Wait for a minute until the screen turns black completely.
  5. Press the Power switch again to restart.
  6. When the screen comes back, start iWriteMusic and see how it works.

iWriteMusic normally starts working properly by doing above.

Please be advised that unless you do above, ANY APPs you ever opened WILL NEVER BE TERMINATED and stay in background. Your device, then, will eventually run out its resources and cause issues no matter how well equipped the device is.

< Unknown Issues >

We always want this app to be bug free. We test the app carefully and remove all the bugs we know at the moment before the release of any new versions. There is, however, always a chance of new bugs that we still don’t know yet unfortunately. The problem is, unless we know what the issue is, we can't fix it. We know you're using iWM in different way with different settings from what we tested and may find new issues. Please email us when you find anything wrong and if you can, attach the data as well so we can find the cause and fix it.

< Auto Save >

iWriteMusic supports AutoSave although you need to activate it. If you want to use it,

  1. Open Menu in EditorView
  2. Select Application Settings, then it will appear on the top of the list.

Please remember that you can enter notes or rests beyond the bar limit.
For instance, you can enter 5 quarter notes in one 4/4 measure.
All the notes/rests over the limit appear in red color and will be ignored on playback, however,
you can, for instance, write a long cadenza in a single bar beyond the bar limit.
So, in this case, enter a note/rest beyond the bar limit first, then make a triplet.

This file contains MIDI data in standard format which you can transfer to other major notation software such as Finale or Sibelius. You can also play it with most of audio players such as QuickTime or Windows Media Player, however you can not play it on iOS devices. iWriteMusic is currently supporting Export Standard MIDI only, which means you can not transfer MIDI data that you created with other notation software to iWriteMusic.
