LPX sustain pedal anomaly - controller default values changing with no apparent reason

[David Pickell]

Hello - just found my sustain pedal not releasing: it's recording alternating values of 127 and 6, rather than 127 and 0. Has anyone else had this weirdness? 

I might just go into the environment and use a transform to subtract the 6 and send correct info to my piano plugin - but honestly, how does this happen?? Anyone seen this?

Cheers - David

Have you tried using another sustain pedal?

Alternately, you could use SNoize to test your current pedal to check if it is working as expected.

What's your sustain pedal connected to? It's possible your pedal doesn't have the right electrical characteristics to trigger the full range of voltage in an input that can handle smooth pedal values...

Launched new session and the error doesn't appear. A bug in my session perhaps? 

That's about the oddest bug I've seen so far. Sustain values 127 and 6!!

Logic is dumb in that way that it just records whatever MIDI events it receives, so the issue is most likely with your pedal or keyboard that sends those values.

Good to hear this is resolved for now. However, should it reoccur, you can download and install the free utility Snoize's MIDI Monitor (https://www.snoize.com/midimonitor/) in order to verify what exact MIDI events your Mac (and thus Logic) is receiving.

The pedal itself doesn't send a CC, it's just an on-off switch. It's the device it's plugged in (i.e. your keyboard) that translates that into CC64.

For most instruments (including hardware), a CC64 value of 0 and 6 are treated the same, only switching if the value is greater than or less than 63. 

Glad to hear the bug went away!

That's true in most cases, but not always https://geekmusician.com/using-sustain-pedal-as-expression-pedal/

You are correct, polanoid, there are "half damper" sustain pedals that are continuous controllers. Not all instruments and controllers respond to them, however. They have become quite common in high end stage pianos.
