Hi List,
This probably isnt the right place, but I'm kind of lost on where to
go from here:
I have an M-Audio Keystation 88es Keyboard. I plug it into my laptop
running KxStudio through USB, and pretty much works perfectly out of
the box. I've had a lot of success running it into LinuxSampler and
running that into Ardour. I pretty much only feel limited by the
sample library I have there.
That and XRuns. I'm still working on reducing those. If I increase my
buffer size in Jack, the keyboard isn't quite as responsive (probably
obvious there). I figure I'll eventually find the sweet spot...
What I do hope someone can help me with is a simple problem. When I
plug a foot pedal into the sustain port of the keyboard, it doesn't
add any change to the signal. The only other experience I have is
using this keyboard with Logic, Garageband, and Main Stage. The
sustain worked like a sustain would in these programs. I wonder if
someone could point me towards unlocking this functionality. Google
searches aren't too helpful with this.
Thanks!

Typically the problem appears when you plug the pedal into an already
connected MIDI keyboard (because of inversed polarity).
Try connecting the pedal first, then plug the keyboard to your PC.

To me, connecting the midi first or after should have no influence,
midi is kind of hot plug.
On another hand, some keyboards need to have the pedal connected
*before* powering on the keyboard, so the polarity of the pedal is
correctly recognised.
You can check with a midi monitor if the pedals affects sending the
"Note off" messages, instead of just listening to the sound produced
by the sampler

Doesn't it depends on the sustain pedal instead? :)

well yes, only if you plug them into a port labelled
"sustain pedal"
;) A Sustain pedal in itself is only a switch. I'm sure you know that

I find it hard to imagine a MIDI master keyboard that would keep track
of pressed keys instead of simply passing switch actions through as CC
msgs, but certainly I haven't seen everything under the sun yet. :)

Hello Clifford,
What kind of pedal are you using? I've got a Boss FS-5U myself which has
a polarity switch. Maybe your pedal has such a switch too and it got
switched accidentally?
Bye,
Jeremy
