+desc: MIDI hold notes range
+author: tomaszpio
+version: 1.0.0
+about:
+  This JSFX plugin implements a "note hold" function, active only within
+  a specified MIDI note range. It is intended for live playing or MIDI
+  processing where one key at a time is held, regardless of Note Off messages.
+
+  HOW IT WORKS:
+  - The plugin reacts only to Note On / Note Off messages.
+  - It works on:
+      • a selected MIDI channel (1–16), or
+      • all channels if Channel = 0 (omni mode).
+  - It is active only for notes within the [Low note .. High note] range.
+  - For any Note On with velocity > 0 in that range:
+      • The previously held note is turned off (Note Off is sent).
+      • The new note is turned on (Note On is sent) and stored as the
+        currently held note.
+  - Note Off messages and Note On with velocity = 0 in that range are ignored,
+    so they do NOT release the held note.
+  - All other MIDI messages (outside the note range, or on other channels,
+    or non-note messages) pass through unchanged.
+
+  SLIDERS:
+  - Channel (0=omni, 1–16 = specific MIDI channel)
+    • 0  => process all channels
+    • 1–16 => only process that MIDI channel
+  - Low note  – lower bound of the active note range (0–127)
+  - High note – upper bound of the active note range (0–127)
+    If Low note > High note, the plugin automatically swaps them.
+
+  TYPICAL USE CASES:
+  - Use a low octave on your keyboard as a "hold" controller area,
+    while higher notes play normally.
+  - Restrict hold behavior to a specific region (e.g., bass notes or keyswitches)
+    without affecting the rest of the keyboard.
