Innerclock Systems is a Sydney, Australia-based hardware manufacturer founded in 2001 by David Lackey and Warren McAlister. The company specializes in precision synchronization, clocking, and timing tools designed to lock together DAWs, drum machines, modular systems, and hardware synthesizers with sample-accurate accuracy, addressing the jitter and latency problems inherent to standard MIDI beat clock.

Their catalog centers on sync utilities rather than instruments. Notable products include the Sync-Gen 3LX, a sample-accurate MIDI, DIN-Sync, and CV clocking interface; GridLock II, a unified hub combining MIDI, USB, DIN-Sync, and CV synchronization; Multi-Split, a dual-input MIDI and DIN-Sync thru box; and the Visual Click Track (VCT). The company's earliest product was Sync Shift, and the lineup has since grown to cover both desktop studio use and Eurorack modular integration.

The brand is a niche specialist known among electronic music producers, modular synth users, and engineers who need tight synchronization between analog hardware and software sequencers. Coverage in Sound on Sound, Gearnews, and discussion on forums such as Gearspace and Mod Wiggler has established Innerclock as a go-to name for studios chasing rock-solid timing between digital and analog gear.

Innerclock Systems has 9 products cataloged on Equipboard, including Converters, Modular Synthesizers, and Utility Plugins. Their gear is featured by 3 artists, with the strongest followings in Electronic. Notable users include The Chemical Brothers, Richard Devine, and Kirk Degiorgio.
