But if you want to built an "pd-independent" device, you can use OSC in arduino - although much harder than simply reading values with pduino - some guys already posted code for sending OSC messages from arduino devices [1], so then you can plug it to whatever you want: pd, ardour, osc-to-midi apps, processing, supercollider :D

A gamepad would definitely be LESS precise as each potentiometer will map data between 0 and 255. But i've never found this to be a problem.

I guess it could, only Arduino is more expensive i suppose. I'll try to provide you with some pictures sometime soon.

Hi Pierre
could you provide more details on how you built your pedal? Could'nt the gamepad be replaced with an Arduino?
Thanks,

Date: Mardi 8 juin 2010, 7h25Hi Achim, You'll have no latency problems with a USB pedal in Linux using the [hid] object. No "noticeable" latency at least.
There are two problems arising when attempting to built a USB pedal : first you need to actually make the pedal (the traditional cry baby
design is probably the easiest way to go), then you need to connect it to a good usb gamepad. I insist on the "good" here because it is essential if you want to have a decent expression pedal. The best would be to test the gamepad before buying it and turning it into a pedal.

Hi Pierre
and thanx for your answer.
I am looking for an expression foot controller. Something working somehow like a wah-wah pedal. But I am unsure if I need a device with an OSC dedicated driver, or if any USB pedal would do the job. What I primarily expect from this device is accuracy, and low-latency.
Do you have any examples (photographs, audio samples) of the device you made? I am curious!

Date: Dimanche 6 juin 2010, 20h40Hi Achim,
I've built
one myself, based on a usb gamepad. I can give you some tips. But you'll have to be more precise about what you really need (expression pedal or just switches?) Pierre

Hi listees
I'm looking for a pedal controller that is accurate enough to send OSC messages to pd, in order to control some effect patches for my guitar.
Can anyone help me in finding a good one, maybe providing a perqsonal experience feedback?
Thanks in advance,
Achim
