OT: Question about keyboard/piano pedals..

[metaltim]

Okay im about to buy a basic pedal for my roland keyboard..
I want it for sustain, and whatever else it can do.
On the roland site it they have one kind (dp-6) that says for "non-latch" operations such as sustaining notes"
what is 'non-latched'
obvisouly sustaining notes is.. but specifically, what is that.
it sounds like what it is, the pedal doesn't 'latch' or stay in the lower position, like a lightswitch. but i want to check on that.

for the Dp-8 it says "High-quality damper pedal with expressive half-pedal capabilities"

what is that.. even though it says "Half-pedal function compatible with Roland RD-600/700, FP-9/3, F-90, KF-90, XV-88 and Fantom-Series workstations"
and I have a roland xp-30
just wondering. can anyone enlighten me??

thanks

As far as i know you have 2 kinds of pedals. The on/off kind, wich makes or breaks a connection (punch in for ptle for example), and you have pedals that are actually faders, so they have more positions between on and off (like a volume pedal). Maybe that is what they mean.

cool thats what i was thinking. BUT.. its weird the dp-6 is 27 bux. it is non latchin.
the dp-8 is 25 bux, also non latching, but it says it has half damper capability, meaning you can apply different amount of sustain to it..

why would the seemingly better one be cheaper than the one lacking this capability??

A nonlatching pedal is a momentary switch, you press the pedal, the switch is turned on, you take your foot off, it's off again.

A latching pedal is an on/off switch, you press and let go, it's on, press and let go again, it's off.

then you have nonlatching normally open, where if you don't press the pedal the switch is open/off, and normally closed, where when you don't press the pedal the switch is closed/on.

for sustain pedals you want a nonlatching pedal, hwoever, Roland has in the past used both normally oepn and normally cloed nonlatching pedals, so make sure you get the correct one by checking the users manual or website.
