Description

XHT Card is a synthesised deep-note-style gesture rather than a bundled sample. Main sets the note position and one-shot destination. The momentary down switch resets the note and launches a one-shot from the start toward the current destination. CV2 also participates in destination control. P2 can clock stepped movement through the note. X controls delay and Y controls reverb.

CV1 input transposes pitch. CV Out 1 mirrors note position unless CV1 is patched, in which case CV Out 1 becomes pitch. CV Out 2 always mirrors note position. P1 gates the note when patched and leaves the note sustained when unpatched.

The separate MIDI build adds MIDI note input, CC1/mod-wheel destination control, sustain pedal on CC64, and MIDI note output of the current chord. MIDI clock is ignored.
