This plugin enables PCStage to be synchronized with an external source of MIDI clocks. The MIDI input device is that selected in PCStage, which routes messages to the plugin, and the plugin's data is saved in the same directory as the current PCStage production, with a '.pcs_midiclocks' filename extension.

By convention, there are six clocks to the beat. Times are shown and specified in beats, which have a clock fraction; 0.3, 4 and 5.5 are valid times, but 2.7 is not.

Initially the clock counter is stopped, which is shown by a greyed-out counter; a Stop message also produces this state. A Start or Continue message causes the counter to run; the former also resets it. Song Position Pointer messages set the clock counter directly, no matter whether it is running.

Each event specifies the time at which it first occurs and, optionally, the period of its repetition thereafter. Events may specify a cue filter, which has the same effect as that available for PCStage's internal triggers.

Also included in this archive is a simple test program which generates MIDI clocks (at a variable tempo) and all other supported messages.
