◆ release_channel()

void Nodes::MidiUtil::Node::release_channel ( int chan )

inline

On all notes / sound off: forget the channel's held keys, or a later scale change would restart their notes.

std::array<std::array<uint8_t, 128>, 17> Nodes::MidiUtil::Node::playing {}

Held keys per output note: two keys can map to the same scale note, which must only stop with the last one.
