The new drum sequencer from Erica Synths is a 16 channel trigger sequencer with all the usual features you would expect from a performance trigger sequencer. One of the nicest things about this is that it has some lovely 909 style buttons for programming the patterns.
The buttons are arranged in a grid style rather than one long line, which in our eyes makes it very easy to visual a sequence.
