I have been trying to use my Sensel Morph with the Witch, but it seems like once I plug it in, it works for really a few minutes at most, then the notes just lock, the keyboard no longer triggers notes.
The device itself will work (note trigger works, dials work, etc…
Since you cannot disconnect the USB and reconnect it without restarting the Witch, this pretty much makes it useless for any sort of performance. The Sensel Morph hasn’t caused me issues with other devices. Using it with Pigments at the moment and it is fine.
