TriggerSeq

A performance-oriented sequencer that is triggered by incoming MIDI notes.

Thanks to Kevin F. for the original idea and for pushing me farther into what is shaping up to be a really cool and useful little tool.

Now with polyphonic support, chuck your chords into the TriggerSeq to see what comes out the other side.

Use it with a monosynth like a 303 clone and dig into the new Tie function to slide up and down octaves from step-to-step.

Store 16 presets and and recall them with a parameter knob, enabling a different kind of live performance.

Features

• Incoming notes trigger a sequence
• Play Mode control
  • Thru = Note-on triggers the sequence to play until the end. New note-ons do not interrupt a currently playing sequence.
  • Choke = Note-on triggers the sequence to play until the end. New note-ons do interrupt a currently playing sequence.
  • Hold = Play the sequence as long as notes are held. It will loop when it reaches the end.
• Pitch can be absolute or relative
  • Scale awareness optional
• Velocity can be absolute or relative
• Rests are supported (non-playing pattern slots)
• Time can be notes or ms
• Slot Duration is multiples of a time base
• Swing control (-95% to +95%)
• Mono or Poly operation (8 voice support)
• Tie function to work nicely with 303s and other monosynths with portamento
• 16 automatable snapshot presets
