808 Snare - Mutations
This post originally appeared on the SS-30M blog on 21/10/21 tl:dr I tried to set my Hexinverter Electronique Mutant Snare (MS) module to match the TR-808, on which it is based. I found that the tuning of the MS 'shells' is quite high and not like most 808s. The original 808 schematic values give a frequency for the high snare oscillator of 499 Hz and later component change brought it right down to about 335Hz. My research, which included checking more examples' frequencies, shows that most 808s and its modern clones use the revised component values and thus a lower pitched snare 'shell'. That's including the Roland ACB digital products. The MS is using the original component values, hence is higher in pitch. Noting the variation in tuning ratio between the two oscillators and also bearing in mind that the Q value changes decay time, it should be possible to modify the MS to match the sound of most 808 snares and clones.
