How to use Tap Trig – the "One Button Samba"
The “Tap Trig” Mode
There is an alternate use for the “Tap Tempo” button. It can be set up to control the playing of notes in the arpeggiator sequence, instead of having the arpeggiator played from the clock. Then that one button, “Tap Tempo” can be used to control the timing of the start of the next note, with the note being held for as long as you hold the button down. In addition the Arp controls – Mode (Up, Down, Order, Random, etc) and Octave both control the notes played with the “Tap Tempo” button. Even when the Arp Mode is set to Chord or Phrase this works, which is a little unusual, and you can also choose different Phrases (a choice of 64) to play as well. The Arpeggiator Length parameter also works so this allows variations to be created.
Also when in Tap Trig mode, the output CV signal labeled “GATE” is controlled with that same one button. You can also do things with the output CV signal “CLOCK” using the PPS option for clock rate – see the manual for more detail.
To get started first set the Tap Trig Parameter (Arp - page 2 #1) to ON. Then turn the Arpeggiator ON and turn Latch on as well. Then use the Keyboard or Pads to enter an arpeggiator sequence, and remember you can use “additive arpegiation” with this if you want as well.
Here’s an example of “Tap Trig” mode being used in a performance by Dominic Au. Here he is using two Hydrasynths, playing one with his left hand and one with his right. Note the additional control he uses during this performance.
A cool trick on the HSK is to turn on the Theremin. Then you can then “play” a complex interplay with your two fingers doing separate rhythms. (Remember Thermin mode reserves one voice for the Ribbon.) I like to use the Arp Phrase mode, played with the “Tap Tempo” with my left index, and the Theremin Ribbon with my right index. This works beause if you try to use the keyboard to play notes it will destroy the arpeggiator pattern you have entered, but the ribbon doesn’t. And remember you lift your hand from the ribbon and the note ends with Hold OFF. I often set the Expression pedal to control the Theremin volume.
Detail from the manual:
Tap Trig
When Tap Trig is enabled the arpeggiator triggers a note every time [TAP TEMPO] is pressed. This lets you walk through the pattern one note or chord at a time, depending on the Mode and other settings.
Note that Tap Trig sends signals only to the Gate output. The Clock out still runs at the selected clock rate.
ADDED: The “Tap Tempo” button can also be set to be used with the Compressor in the Sidechain Parameter.
