when first playing a Machinedrum back in 2007, I was flummoxed by the seemingly arbitrary designation of bd, sn, ht, mt, lt, cp, etc etc
ignored the convention and in fact as a statement of individual freedom and personal expression, made sure to put my samples on completely differently labelled slots.
but then one day when i noticed the same convention would be used on the Digitakt, thought … well why ever not just follow the convention, it isn’t like not following it is advantageous in any way whatsoever.
developed my own code …
bd is bassdrum, yes.
sd is snare drum, cool.
but then … high tom? when do i use a high tom? not often.
but the letters ht kind of represent “hat”.
so i always put the high hat on ht.
medium tom, mt, is kind of mid-range like a vocal sample is often mid-range.
so the slot mt is saved for a vocal or mid range keyboard sample.
The low tom is also the same frequency range as a bass guitar or synthesizer, so the “Lt” slot is used for a bass sample, or a tom drum of any sort.
anyway just writing about the subject as it is kind of bizarre and yet worth talking about i guess.
the idea with physical instruments is achieving economical muscle memory,
and to some degree, drum machines and sequencers are similarly benefited from some form of arbitrary habitual designations.
