C_COUNTER cannot count backwards…

[jfcharles]

Hello,

It seems that the increment of a counter may not be set to a negative value. This is very unfortunate: makes it difficult to implement a "UP" and "DOWN" triggers to trigger the "previous" value in a STEXTKNOW, and not only the "next" one (for instance to add a "previous chord" button to factory preset 733).

Any workaround? Any pointer?

Thanks.

…just quickly off the top of my head…

would using a control math module work, like C_SUBTRACT or C_MULTIPLY by -1?

Well, yes, that means making your own counter, not using the COUNTER, like that:

HEADM adc 2 2 adc-null adc-null CounterWithAdder "" 3 count-obj up_trigger-obj down_trigger-obj ;=300,-25,100,0
TRIGGER up_trigger "" UP ;=100,0,100,0
TRIGGER down_trigger trigger DOWN ;=100,125,100,0
C_MULTIPLY c_multiply down_trigger-out -1 ;=250,125,100,0
C_ADDER c_adder1 2 up_trigger-out c_multiply-out ;=375,0,100,0
C_ADDER c_adder 2 c_adder1-out c_adder-out ;=600,0,100,0
MONITOR count c_adder-out "current count:%.f" count ;=825,0,100,0
TAIL jfcharles2009

Now, let's try and add a reset function to that.

Following up on my previous message (I see it hasn't been approved yet):

Here is the version with a reset trigger, if anybody is interested.

HEADM adc 2 2 adc-null adc-null CounterTest "" 4 count-obj up_trigger-obj down_trigger-obj reset_trigger-obj ;=300,-25,100,0

TRIGGER down_trigger trigger DOWN ;=100,125,100,0
C_MULTIPLY c_multiply down_trigger-out -1 ;=250,125,100,0
C_ADDER c_adder1 2 up_trigger-out c_multiply-out ;=375,0,100,0
TRIGGER reset_trigger "" RESET ;=100,275,100,0
