There is no generally valid Matrix for the fourth
group "VARIOUS" like in the three previous special groups. And
that's the case because with each one of the different drum boxes are
various drum and percussion sounds available, that need varying patterns.
A drum trax with toms, as
you can see on the three sample tracks of the following graphic, contains three
already mixed instruments per track per pattern (hi/mid/low tom). A TR-808 does have tom sounds,
so therefore you will find more patters with varying percussion
instruments (see track sample of graphic above) like Shaker, Maracas, Clap and so on.
In this special sound group you
can also do a lot of listening and trying out !
