According to the manual
Unfortunately, some hosts, like Melodics (learning platform) does not support hihat variations via CC messages and require separate messages for open/closed sounds. Could you please consider implement this option in feature firmware updates?For hihats, eDRUMin employs a system where only 1-3 MIDI notes (tip / edge / bell) are
used in combination with a MIDI CC message corresponding to the position of the pedal.
The actual sound that is triggered is handled by the drum sampler
Thank you.
