Tone+FX 3.1i — output ceiling, store guard, smoother ratios

Tone+FX 3.1i — output ceiling, store guard, smoother ratios

A six-page master FX suite for the Digitone mk1 — RING · FOLD · TILT · CRUSH ·
PITCH · STEREO — plus the output meter and the animated TONE+FX boot splash.
Everything ships as one elemod.

Install

One file is the whole suite: tonefx-3.1i.elemod bundles the boot splash
plus digictl and the FX mods into a single format-2 mod, so it combines
with your other mods. It does not include the core: install
core-dn1-2.0a.elemod (required; elekloader provides it) plus anything else you
use.

New in 3.1i

• Output ceiling: a final soft limiter keeps the master mix below the 24-bit
  full scale (transparent below ~-2.5 dBFS, asymptotic max ~-0.7 dBFS), so a hot
  flanger-feedback / pitch-shift / drive setting cannot hard-clip. The flanger
  feedback write is clamped too.
• Stock OS events can no longer move a DIGI parameter. The per-pattern sync
  now adopts its block only if it still carries the "DGX1" magic — this fixes
  the reported TILT/EQ jumping when PAGE (or other keys) are pressed.
• Bounds fix (encoder accumulator), and the pitch-shift ratio now glides.

Tested

• Compiles clean (.run 20904, .bss 25270, imports nothing); link
  byte-verified (sections 2/4/5/6/7/8; ~86 KB RAM spare, ~1.69 MB flash spare).
• Emulator (dn1-3.1i): boots, settles, dsp_running=2; all six pages present.
• Hardware: confirm the EQ-jump fix and that the ceiling is inaudible at normal
  levels.
