Double Tap + Hold Trigger (nesting OnSustain)?

alexs1

Does anyone know how I could code a double-tap+hold trigger? For example, a binding could record and overdub on single press, double click Stop, and double-click+hold would TrackReset. This how the Ditto X1 hardware looper works, for reference.

Theoretically, it can be done by nesting OnSustain within an OnRepeat block, right?

#name doubletaphold
#sustain limit 1
#repeat limit 2

if mode == “reset”
Record

if mode == “play”
Overdub

if mode == “Overdub”
Overdub

function OnRepeat {
if repeatCount == 2
Stop
function OnSustain
if sustainCount == 1
TrackReset
}

This is just a sketch script, I’m totally unclear how the syntax should look (braces included) for the Double-Tap+Hold chunk.

Basically, is it possible to wrap Sustain within Repeat to achieve this kind of trigger, or would there be another way?

I think nesting is not possible. OnSustain will not be triggered. They both need to be "visible" on the "top level" of the Code.

But I achieved Double Tap + Hold with an additional clickCount variable, that is visible outside OnRepeat.

Just declare on the top:
variable clickCount = 0

And in OnRepeat write:
clickCount = repeatCount

And within OnSustain write:
if clickCount == 0 {
// normal Hold
} else if clickCount == 1 {
// double tap + Hold
}

I think the if-clauses always need brackets. You can only ommit them if you write the commands directly after ther if statement, eveything in one line like:
if clickCount == 1 TrackReset

Oh cool, thanks for dropping the reply and example! I’ll do some testing with the brackets. Definitely nice to save some head-scratching over this.

Still need to spend some time processing this, but it is possible to have both OnSustain and OnRepeat functions in the same script. Here is one I use for testing, there is a lot of noise in here you would want to filter out.

#name Repeat and Sustain Me
#repeat 500 2
#sustain 1000 4

var foo = 42
static bar = 69

print "Starting"

function OnRepeat(repeatCount repeatDelta repeatElapsed) {
  print ("Repeat " repeatCount repeatDelta repeatElapsed)
}

function OnTimeout(repeatCount repeatElapsed) {
  print ("Repeat Timeout " repeatCount repeatElapsed)
}

function OnRelease (sustainCount sustainElapsed) {
  print ("Release" sustainCount sustainElapsed)
}

function OnSustain(sustainCount sustainElapsed) {
  print( "Sustain" sustainCount sustainElapsed)
  print( "foo" foo "bar" bar);
  bar = bar + 1
  foo = foo + 1
}
