Hi all,
I´m going to build a CV Keyboard.
I have to go with switches, since the keyboard I´m going to use is from an old reed organ and therefore it got no switches or anything else electronic on it.
I read here in the forum that it could be that the pitch changes, if there are more than one key is pressed down, depending on the switches used.
The forum says, to avoid this, you could use reed switches.
Can I use ANY reed switch or do I have do look after special values or something?
Can I use also tactile switches instead, which I would prefer, and if, do I have to look after something here, either?

Thank You

Hi,

Se my response to a similar question:

http://electro-music.com/forum/topic-55006.html

I don't see why it should matter if you use tactile or reed switches, as the current will take the path of least resistance either way if you press more than one key at a time. The keyboard controller details should explain this. I used the MFOS design:

http://www.musicfromouterspace.com/forums.html?MAINTAB=SYNTHDIY&VPW=1317&VPH=500

Provided that the reed/tactile switch has neligible resistance (which it should have), I can't see any difference that it would make and I think that tactile switches are a far better alternative (although some may prefer the magnet + reed switch route).

Hope this helps,

Gary

It just depends on what you want to have the keys "feel" like. If you salvage a keyboard and you like its action and want to maintain that, then reed switches (plus magnets remember) might be the way to go. The tactile switches I've used have a sharp click which might be annoying. Personal preference really. Both are going to have negligible resistance.

Yes Feifer, I have to concede that keyboard felt a little weird with tactile switches, but I got used to it. As you say, if you want a more natural feeling keyboard, the reed switch/magnet route is probably better, but as you say, it's a matter of personal taste.
