This is an off shoot of Jesse Hopkins "Humanization" thread.
PPQN is a software controlled MIDI sequencing resolution for “Parts Per Quarter Note”. Most MIDI software sequences support multiple PPQN values as indeed does SONAR . See its [Project] Options menu, and its “Clock” submenu in its section called “Ticks per quarter note” which supports resolutions of 48, 72, 96, 120, 144, 168, 192, 216, 240, 360, 384, 480, 600, 720, and 960. The MIDI Spec uses 24 PPQN for MIDI Clock Sync, so higher resolutions which have the factors of 24 in common will properly sync to it … but those that don’t … <g>. Direct access to note clock tick start and duration values are usually accessed in any MIDI sequencer’s “Event List” Edit Window, such as the one in SONAR.
Hardware based MIDI sequencers, such as the MC-80, and various keyboard “workstations”, tend to be restricted to one PPQN such as 48, 96 or 192. Obviously computer based software sequencers are more versatile :>)
