Well humanisation is a very open ended phrase, but if we first stick to swing or what is sometimes called groove quantisation then I guess we need to look at how it’s represented in existing software and what we think it means.
Firstly how it’s implemented - sometimes this is represented either solely at the global level e.g. the Swing Knob on this Drum Trigger Sequencer module in Voltage Modular that goes between 50% and 80%
sometimes you can set a global swing or have more granular control over individual drum channel swing e.g. in the XLN Audio XO plugin below you can see on the right there are named swing settings (named ‘Groove’) applied to the FLEX 2 and CLAP drum channels.
I agree what exactly ‘swing’ is may be open to debate, but most sequencers and drum machines seem to reference some values between <50% and >50%, defaulting to 50%, that applies to note timings - move a swing knob to the left, the value goes lower than 50% so note timings tend to slide earlier (I don’t know how the exact voodoo works, but it seems to be somewhat probablistic) and higher than 50% the timings tend to slide later - so it’s a way of getting a track to sound a little like a drummer that’s either pushing or dragging with respect to a metronomic beat.
Humanisation is hard to pin down, but tends to be implemented as a way to define the range by which a sequencer’s triggered note duration and/or velocity can vary from the note event as defined in the sequencer e.g. if we think in terms of a note with a velocity 100 and duration 1.0 s and the humanisation range setting for both duration and velocity is set at plus-or-minus-10% then velocity would randomly vary between 90 and 110 and duration between 0.9s and 1.1s.
I may have done a bad job of explaining myself, but I thought I’d at least try to rather than just dropping a link to some YouTube video that purports to explain what swing is, like this video about how to apply it in Ableton Live
Oh and after all that I forgot to add the great work you have done on the sequencers, it’s nice to have a familiar place to arrange in amongst the (fun) sea of modular madness.
