Christopher11 Posted November 13, 2021 Share Posted November 13, 2021 Forgive me, this isn't directly about Logic. However, I have one of those inexpensive smallish rectangles, Yamaha sustain pedal. The polarity is inverted: it's always sustaining until pressed. I tried it with my Korg M3, my main controller, and an Oxygen 88. It works but the polarity is inverted. There must be a fix for that. I read one about restarting the keyboard, but I think that only works for Yamaha keyboards. Thank you for any thoughts. Quote Link to comment Share on other sites More sharing options...
Atlas007 Posted November 14, 2021 Share Posted November 14, 2021 You could use a Transformer object in the Environment and reverse map its values. You would connect that Transformer object between the Physical Input object and the Sequencer Input object. Following the setup below should solve your issue. Once set accordingly, save the project as a template which you can use as a starting point in the future (saving you from having to set that up again every time). There might be other solutions available... Quote Link to comment Share on other sites More sharing options...
Christopher11 Posted November 15, 2021 Author Share Posted November 15, 2021 Thank you. That's very helpful. However, I wonder why the polarity is inverted on this pedal. There must be a way to fix it at the source, so I can use it with the M3 whether or not with LPX. Quote Link to comment Share on other sites More sharing options...
