[PD] Looking for a pedal controller

[Achim Bloch]

Hi,
what kind of gamepad would you recommend?
I first thought of using an Arduino instead, but it seems that the analogic/digital converters are quite light: "The Arduino board contains a 6 channel (8 channels on the Mini and Nano,
 16 on the Mega), 10-bit analog to digital converter. This means that it
 will map input voltages between 0 and 5 volts into integer values 
between 0 and 1023." Would a good gamepad be really more precise?
Thanks,
Achim

Hi 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!

Hi 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?)

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
