Splitting a live hardware rig into two independent halves guards against single-point failures

A live hardware performer can build two near-independent signal chains — each capable of running the set alone — so that if one side is disabled (spilled drink, module failure) the other can continue without interruption. Florian Meindl’s setup has a left side (Pioneer Toraiz SP-16 + Arturia MicroFreak, clock master) and a right side (Eurorack + Arturia BeatStep Pro, capable of running from its own clock). The two sides share a MIDI sync signal under normal conditions; losing the left side simply means the BeatStep Pro reverts to its internal clock. The tradeoff is complexity: each half must be self-sufficient in sound and rhythm, which constrains how many tracks you can run. The design principle applies equally to software/hardware hybrid rigs and purely software setups (e.g., two DAW instances on separate machines).

Examples

Left side: SP-16 sampler + MicroFreak synth (audio of MicroFreak routed into SP-16). Right side: Eurorack modular + BeatStep Pro sequencer. SP-16 sends MIDI clock to BeatStep Pro; if SP-16 fails, BeatStep Pro’s own clock takes over.

Assessment

Describe what happens to the BeatStep Pro’s timing if the SP-16 goes down in Meindl’s rig. Then sketch a two-path redundancy design for a DAW-based live set with one laptop.
