Dominant seventh from G doesn’t work #5

Closed maximal closed 9 years ago

maximal commented 9 years ago

Trying to press a dominant seventh chord from G: G—B—D—F.

In the combination of B + M + W + R last pressed key doesn’t sound.

When trying B + M + W + T (magor triad G—B—D—G), all is just fine.

Chromium 41.0.2272.76 Ubuntu Linux 14.10 (64-bit)

Hi Maximal. Thanks for your interest! I’m experiencing the same in Chrome 41 for OS X 10.10.2, but my suspicion is that it’s a hardware limitation of keyboards rather a software bug. In addition to the key combination you’ve mentioned I’ve found others—pretty much by randomly mashing down as many keys as I can at once ;) I doubt keyboards were designed to reliably transmit many keypresses simultaneously as this isn’t necessary to support regular typing.

Meanwhile, scripting (rather than key-pressing) the simultaneous activation of those four Triggers you mentioned works as expected as does key-pressing B+M+W and mousing over the final Trigger. Can anyone confirm that this is a hardware thing? Either way, solutions appreciated!

I’m going to accept @rojaro’s n-key rollover link as nearly-proof that it’s a hardware limitation and close this issue. (Flimsy as a proof, I know, but we’re not designing space rockets here!)
