Ctrl In Perf for Elektron Analog Rytm

EXP/CV IN 1 or 2 plays a performance macro: a PERF DEST row in the CONTROL INPUT menus sends the jack to PF1 to PF12.

Module version 0.1.0-experimental. Base firmware: 1.74.

About this module

Ctrl In Perf adds PERF DEST to GLOBAL > CONTROL > CONTROL INPUT 1 and 2 in CV and EXPR modes. Set it to PF1 to PF12 and the jack sets that performance macro as its knob would: CV ZERO LEVEL to CV MAX LEVEL, or the learned EXPR range, maps to 0 to 127, the macro's performance locks follow and its pad lights in PERF mode. The jack always wins: while it drives a macro, that macro's knob and pad are overwritten at the next audio block. The value moves in whole steps and holds still against converter noise. Nothing is sent over MIDI or Overbridge, and the kit is not marked edited. PERF DEST is saved with the globals slot. It is a port of MrScruff's rytm-mods 0017-ctrl-in-perf to OS 1.74.

• A CV or expression pedal plays any of the twelve performance macros.
• Set up in stock's CONTROL INPUT menus.
• The macro's locks and its PERF pad light follow the jack.
• Each jack has its own destination.

How to use it

1. Plug a CV source or an expression pedal into EXP/CV IN 1, then open GLOBAL > CONTROL > CONTROL INPUT 1 and set MODE to CV or EXPR (for EXPR, run EXPRESSION LEARN).
2. Set PERF DEST, the last row, to PF1 and leave the menu.
3. Give performance 1 some locks (hold PF1 in PERF mode and turn knobs), then move the jack: the locks follow it, and pad 1 lights with the level in PERF mode.
4. Set PERF DEST back to OFF to give PF1 back to its knob and pad.

Controls

PERF DEST

In GLOBAL > CONTROL > CONTROL INPUT 1 and 2, MODE CV or EXPR: the performance macro the jack sets, OFF or PF1 to PF12.

Compatibility notes

• Stay within the jack's -5 V to +5 V.
• While a jack drives a macro, that macro's knob, pad and CC 35 to 47 are overwritten at the next audio block, about 0.7 ms later.
• PERF DEST belongs to the globals slot and is saved with the project's globals: a new project, or one saved without the module, reads OFF.
• A jack in OFF mode, or in another module's mode, drives no macro. CONTROL IN 1 MOD and 2 MOD still play as stock beside it.

Test evidence

Hardware on an Analog Rytm MKII, OS 1.74: PERF DEST shows and steps in CV mode, MODE OFF hides it, and PF1 is kept over a project save, reload and power cycle (CPH2, 2026-11-08). A CV source at 0, 2.5 and 5 V drove macro 1 to 0, 64 and 127, and a lock on performance 1 followed (CPH3, 2026-11-09). EXPR mode and CONTROL INPUT 2 were not run on the unit.
