2018 MacMini, i7, 32 GB, OS 10.14.4 Mojave
Sensel Morph x 2, firmware 0.19.180, Sensel App 0.19.32
Bitwig Studio 2.5 (also tested in Ableton Live 10 and Logic Pro X, latest versions)
In all Piano-based keyboard layouts (Piano MIDI and Piano MPE) the pitch played tracks fine from C3 to C4, but it jumps from C4 to F#4 when the C#4 key is hit (a 3 semitone jump!), and to G4 when D4 is played and so on until C5 (small C key at the top of the Morph) which plays the note C3!! Both my Morphs are doing this (even after reinstalling the firmware and sending piano maps to both Morphs).
