seq-l

seq-l is a simple live looping midi note sequencer.

– midi input is recorded in a fixed length, syncronized looping note sequence. sequences can have up to 64 notes. the top row of pads shows the current 8 sequence steps while playing.
– input replaces existing notes in ‘sub’ mode, adds to them in ‘add’ mode, or can be disabled while playing the loop in ‘play’ mode.
– the ‘X’ pad deletes notes while held down. when the host is stopped, hold ‘X’ and play a midi note that will then control ‘X’. hold ‘X’ and tap the same note again to undo.
– ‘copy’ copies the current sequence to the next one selected.
– ‘p2’ shows a 2nd set of knob controls for swing, repeats and velocity fades.
– the ‘a’ – ‘d’ pads select one of 4 sequences. tap a pad to switch to the sequence. tap again while the host is stopped to show the next page of 8 steps. hold ‘a’ – ‘d’ and play a midi note which then will select the sequence.
– hold the shift button to reveal midi note triggers.
– ‘len’ sets the number of steps in all sequences, *only when the shift button is down*. this clears all sequences.
– ‘1/N’ sets the step size.
– ‘dur’ sets a duration for new notes in quarter notes. if ‘dur’ is zero new notes have the played duration.
– ‘swing’ delays even numbered steps by a percent of the time to the next step.
– ‘repeats’ sets a limit on how many times a note is played before deletion. it takes effect when notes are input. if ‘repeats’ is zero notes repeat indefinitely.
– ‘dv’ sets a velocity delta, which is subtracted from played notes so they gradually fade away. notes are deleted when velocity becomes zero or less.
– hold shift to show alternate pad controls. ‘copy!!’ copies the current sequence to all others. ‘reset’ sets default control values. ‘X!!’ clears the current sequence.

    Hi,
    Your script has real potential. It would be nice if one could set the midi channel per sequence and if the sequences A – D could play simultaneously.
