Nonlinear Circuits 1050 Mix Sequencer
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
