fx_miUGens

Eurorack-born effects for the norns fx mod

Seven effects built on mi-UGens. Each one can sit on send A, send B or the insert slot, under any script.

Effect	What it does
granular	Granular processor with four quality modes (hi-fi to dirty tape) and a built-in reverb
texture	Texture processor: granular, stretch, looping delay and spectral modes
reverb	Lush reverb with freeze
lowpass	4-pole analog-style lowpass, one per channel; stereo spread pulls the two cutoffs apart
mulaw	µ-law companding: 8-bit crunch, more of it the harder you drive
metamod	Cross-modulation, ring mod, vocoder. The carrier is a built-in oscillator at note, modulated by the input; or set carrier to input left to modulate left by right
resonator	Strings and modal resonator excited by the input. Loud transients strum it; raise strum threshold to stop that

Install

Install the fx mod.
In maiden: ;install https://github.com/carlosedp/fx_miUGens
SYSTEM > MODS: enable fx and fx_miUGens, then SYSTEM > RESTART.
If mi-UGens isn't installed yet (or is an older copy without MiBeads or MiWarps), open SYSTEM > MODS > FX_MIUGENS, scroll to install mi-UGens at the bottom and press K3. It downloads the latest norns-mi-UGens release and moves older copies aside. Then SYSTEM > RESTART again.

Use

Load any script. Under PARAMETERS > EDIT, the fx miugens section has one folder per effect; set its slot to send a, send b or insert. Scripts that support fx sends have send a / send b levels; insert processes everything.

Pick your effects: SYSTEM > MODS > FX_MIUGENS lists every effect. E2 to move, E3 or K3 to switch one on or off, K2 to leave. Switched-off effects don't add params. Changes apply the next time a script loads. Effects whose UGen isn't installed show as missing; the last row installs or updates mi-UGens.

Good to know

CPU: granular, texture and resonator are heavy. Running two of them at once on a norns (CM3) is likely to crackle.
fx_grains and fx_resonator can stay installed. fx_miUGens uses its own names, so they don't clash.
A missing UGen only disables that effect; the rest still load. If the fx mod itself is missing, though, SuperCollider can't compile these classes and norns' audio won't start, as with any fx effect.
A script loads its PSET before mods add their params, so these settings aren't restored from it, as with other fx effects.
