I purchased a Y-cable to split the magnetic and Piezo pickups from my Majesty to the FX3. To start, I'm using the @Cooper Carter 2023 Petrucci Rig, which has inputs 1 & 3 mapped for this purpose. I have the magnetic pickup plugged into input 1 and the Piezo into input 3 right (tried left also). Am I overlooking something obvious, or is there just no way to have both in stereo when using a Y-cable? As is, magnetic is stereo but Piezo is right or left only. Thanks.
