v7.3.0

What's new

• zeptocore: Added realtime stretch control for zeptocore playback. Hold B and turn Knob Z to move from bypass into increasing stretch amounts.
• zeptocore: Added a Retrigger volume ramps toggle using buttons 13 + 14 + 15 + 16. It is enabled by default and lets retriggers ramp volume back in instead of always staying flat.
• EZEPTOCORE/ectocore: Added realtime stretch behavior random-effect/rune workflows when the selected rune is timestretch-only.

What's changed

• Updated MIDI CC 20 to control realtime stretch instead of bass volume.
• Updated Zeptocore filter handling so the filter control behaves as a low-pass cutoff when the DJ filter mode is disabled.
• Clarified the quickstart and combo docs for volume, tempo, sample selection, random jump, random effects, random tunnel, quantize, and realtime stretch controls.
