You’re welcome.
1. No, the Rose cannot accept a TRS MIDI signal directly from another device, you need to use a MIDI DIN > TRS convertor.
2. No, it will not automatically be mapped. In this configuration, the expression pedal will be outputting a MIDI CC from the MIDI controller. On the Rose, you can decide which CC# (1-31) will control the morph. It will depend on which MIDI controller you choose, but you’ll need to configure this to output the correct MIDI CC.
3. No, the Rose needs connect to a USB host device, such as a computer. You can send MIDI data from your computer to the Rose over USB using a DAW or program that can output MIDI data.
