[Bug] D5 and D4 cannot be pressed simultaneously if Sustain is active
Closed this issue · 6 comments
Description
Most keys can be played in unison to create chords, such as A4 and A5, or E5 and C4, but D4 and D5 cannot be played in unison while the Sustain feature is active. If it is attempted, only D4 plays.
Reproduction steps
- Open Live keyboard
- Set Keyboard mode to Piano (other modes not tested)
- Set keyboard scale to G (other scales not tested)
- Set Upper and Lower to Celtic Harp (some other instruments tested, but not many)
- Hold down Sustain button (spacebar)
- Attempt to play D4 and D5 (B & T keys) simultaneously
Actual behavior
When D4 and D5 are clicked simultaneously when Sustain is active, only D4 plays. It is correctly sustained, but D5 is not played.
Expected behavior
When D4 and D5 are clicked simultaneously when Sustain is active, both D4 and D5 play in a sustained manner.

You may be encountering a keyboard ghosting issue, which means your keyboard can only register a limited number of keys being pressed simultaneously. This happens a lot with built-in laptop keyboards and desktop models but most quality gaming PC keyboards have full anti-ghosting.
What keyboard model do you have ?
It's so old the label has degraded, so I'm not sure. It's a pretty standard
dell keyboard that came with an old PC of mine way back in the day. Would
keyboard ghosting affect purely the volume of keys pressed, or would it
differ based on which keys were being pressed? It works just fine with
other chords.

As an alternative solution, would it be possible to add a Sustain toggle
rather than have it be purely dependent on the spacebar being held down?
I'm wanting to play songs that I originally learned on the Kalimba, and
they sound terrible without nonstop sustain.

You may want to check the FAQ https://github.com/LenweSaralonde/Musician/wiki/What-the-FAQ#why-some-keys-dont-register-when-i-play-simultaneous-notes-on-the-live-keyboard
Regarding the sustain toggle, it’s a good idea, I’ll consider implementing it later.
Many thanks!
