Tone+FX 2.2a

Tone+FX 2.2a — per-pattern settings, stock-scaled controls

The DIGI FX / FILTER / FOLD-EQ settings are saved per pattern, like stock
parameters (they follow a pattern switch / reload and travel with a project
save), and the RING/FOLD/EQ controls now use the stock 0..127 scale.

Packages

core-dn1-2.0a, digimeter-1.1, digieq-1.1, digiring-1.1, digifold-1.1,
digifilter-1.0, digictl-1.6.

Changes

• digictl 1.6 keeps the 17 FX parameters in a reserved block inside the
  saved pattern data. A fresh pattern adopts the current values; a pattern
  reload that rewrites the block is detected and adopted.
• Stock-scaled parameters: RING depth/rate, FOLD amount and EQ LOW/HIGH are
  now 0..127 (one step per notch), scaled inside the DSP, instead of the old
  large ranges. EQ centre 64 = flat; defaults: ring depth 51 / rate 6, EQ low 33
  / high 111.
• Page fix: the DIGI FOLD / EQ page title no longer clips the top row, and
  the leftover MOD readout was removed (the LFO destination bridge stays
  parked, off by default).
• No new key or encoder is taken.

Tested

• Real hardware (a Digitone mk1): stress-tested with the full suite — the
  build boots and holds up under long, busy patterns, and the per-pattern
  settings survive pattern switches, reloads and power cycles.
• Emulator (dn1-2.2d, test tags 2.2a…2.2d): boots and settles,
  dsp_running=2; the master pages and live render run with 0 faults; the
  fold/EQ layout is clean; the settings persist per pattern
  (digiemu_pattern_store.py).

Known bugs / future fixes

• Slider behaviour (match the stock parameter widgets), encoder acceleration,
  per-parameter value readouts and consistent page titles/units.
• LFO destinations for the DIGI parameters remain parked (off, no page
  control).
• CPU/DSP load is the user's to manage on busy patterns.
