This is my adaptation of LMNC’s 8 Step Sequencer Keyboard . Main modifications are:

  • Added rotary switch to select sequence length or pattern
  • Added switches to turn off outputs for steps
  • Added Zero gate input
  • Added “Reverse time” switch (which exchanges the roles of the Forward and Backward gate inputs)
  • Software change allows you to hold down multiple buttons and only those steps will be used
