I have a question regarding keyboard encoders and multiple key presses. If the encoder is running in matrix mode at 3 x 21, does that mean I can press 21 keys simultaneously and have the encoder see all of the key presses? Is there a limit to how many keys it can see (does it use a buffer)? This is assuming no ghosting problems, either due to diodes or a good key layout.
If it depends on the encoder, bear in mind that I am probably going to buy the LP24 from Haggstrom.
