- Attempt must be performed on a MIDI-capable acoustic, hybrid, or digital piano with non-adjustable hammer weighting.
- Minimum down-weight is 56 g. Before the attempt, performer must demonstrate key weight using a calibrated scale and include this in the video.
– Keystrokes are tallied via a MIDI plug-in that applies a 25-millisecond duplicate filter. A second, unfiltered count must be recorded for comparison. Both raw and filtered MIDI data files must be submitted.
– Clock starts automatically on the first keystroke and stops exactly 60 seconds later. Any notes struck after 60 seconds are not counted.
– Each strike must be a distinct note. Simultaneous chord hits, ghost notes, or mechanically repeated actions count as one under the 25 ms filter. No external devices, auto-repeat functions, or prepared mechanisms may assist the hands.
– A single, uncut video must show: full view of performer, keyboard, and hands throughout; key-weight verification; computer screen (or split-screen capture) displaying the plug-in settings and live count; immediate on-camera read-out of the final totals.
– Either a notarized statement or two independent adult witnesses must attest to the accuracy of the timing and count. Signed documents with contact information must accompany the submission.
– Submit: raw & filtered MIDI files, plug-in binary or source (or checksum), and a still photo of the key-weight test.
- To claim a new title, the final filtered total must exceed the standing record by at least one (1) keystroke.
– All other standard RecordSetter rules apply, including adherence to good sportsmanship and truthful representation of results.
