Timing doesn't get tighter than this // Gridlock II interface for CV, MIDI, USB & DIN Sync

"If you’ve ever struggled with MIDI jitter, sloppy DAW clocking, or keeping vintage synths and drum machines locked in time, the Innerclock Systems Gridlock II might be the ultimate solution.

In this video I take an in-depth look at Gridlock II, a professional MIDI, DIN Sync, USB and CV/Gate timing hub from Australian company Innerclock Systems, designed to deliver rock-solid timing with jitter as low as 20 microseconds. Rather than relying on unreliable DAW MIDI clock, Gridlock II generates its own ultra-accurate timing using an audio-based plugin approach — and the results are immediately audible.

I demonstrate how Gridlock II integrates vintage non-MIDI synths like the ARP Odyssey, Minimoog, Prodigy, Promars, Juno-60, alongside modern USB and MIDI gear, all appearing cleanly inside Logic as named instruments. You’ll see how MIDI, DIN Sync, USB MIDI and CV/Gate can coexist in one system, with every device locked tightly to the beat.
