// nisps/modes/slp_workshop.hpp — SLP-Workshop mode binding.
|
||
|
|
//
|
||
|
|
// The Synth Library Portland workshop instrument. It reuses the MEMLCelium
|
||
|
|
// engine and MLP shape verbatim (4 input channels → MLP[4,10,14,18,56] →
|
||
|
|
// MEMLCeliumEngine, sequencer ticked internally in process()), but exists as
|
||
|
|
// a distinct mode so the workshop firmware carries its own identity (preset
|
||
|
|
// dir, display name) and foregrounds the adaptive-learning gestures that now
|
||
|
|
// live in ModeBase for every mode:
|
||
|
|
//
|
||
|
|
// - Jolt — held gesture, continuously morphs a scatter of weights and
|
||
|
|
// freezes them on release (Base::jolt_press/jolt_release).
|
||
|
|
// - OU explore — Ornstein-Uhlenbeck random walk on the output vector
|
||
|
|
// (Base::set_explore_intensity).
|
||
|
|
//
|
||
|
|
// Both were ported from upstream memllib InterfaceRL (see ml/jolt.hpp,
|
||
|
|
// ml/ou_noise.hpp). Because they sit in the shared base, the synthesis
|
||
|
|
// mapping here is identical to MEMLCeliumMode — only the surfaced controls
|
||
|
|
// and identity differ.
