8-channel audio sequencer and submixer for Eurorack

24 HP Eurorack module

The 1050 Mix Sequencer is a legendary 8-channel mixer and step sequencer for Eurorack, inspired by the Moog 2500 series. It cycles through up to 8 audio channels in programmable sequences, gating each channel open in turn, while also functioning as a flexible sub-mixer with independent level controls and two submix buses — producing rhythmic, gate-driven audio switching effects with musical precision.

Features

8 audio input channels with individual level knobs
Color-coded channel groups (two groups of four) for sub-mixing
8 Channel On/Off buttons with LED indicators for manual and sequenced channel selection
8 Exclusive-On solo buttons for channel preview and soloing
Three-way Counter/Mixer switch for dual 4-step, hybrid, or single 8-step sequencing
Internal pulse generator with variable rate control
External clock input (EXT ADV) for externally advancing the sequence
EXT GATE LINK 12-way connector on module underside for master/slave operation with 1027 module
EXT GATE enable/disable switch for master/slave gate control
Level A and Level B submix master knobs for independent group or global level control
Dual outputs (OUT A and OUT B) with split or combined routing options
Manual Advance momentary switch for step-by-step manual sequence control
