r#"Tracker (based) Sequencer
|
||||
|
||||
This sequencer gets it's speed from the clock source. The 'clock'
|
||||
signal can be interpreted in different modes. But if you want to
|
||||
run multiple sequencers in parallel, you want to synchronize them.
|
||||
For this you can use the 'trig' input, it resets the played row to
|
||||
the beginning of the sequence every time a trigger is received.
|
||||
|
||||
Alternatively you can run the sequencer clock using the phase mode.
|
||||
With that the phase (0..1) signal on the 'clock' input determines the
|
||||
exact play head position in the pattern. With this you just need to
|
||||
synchronize the phase generators for different sequencers.
|
||||
|
||||
For an idea how to chain multiple tracker sequencers, see the next page.
|
||||
|
||||
This tracker provides 6 columns that each can have one of the following
|
||||
types:
|
||||
|
||||
- Note column: for specifying pitches.
|
||||
- Step column: for specifying non interpolated CV signals.
|
||||
- Value column: for specifying linearily interpolated CV signals.
|
||||
- Value column: for specifying linearly interpolated CV signals.
|
||||
- Gate column: for specifying gates, with probability and ratcheting.

Tip:

If you want to use the end of a tracker sequence as trigger for

something else, eg. switching to a different 'tseq' and restart

it using it's 'trig' input, you will need to use the gate output
