Pd: bendout object constantly writing its value to console

Sharptone

Hi, I use the following patch with a potentiometer at analog input 2 to send bend values to a third party software (Ample sound).

[adc~ 5]
I
I [loadbang]
I I
I [metro 50]
I /
I/
I
[snapshot~]
I
[* -9856.8] <--- brings range values from 0 - 0.831vdc to -8192 - 0
I
[bendout]

It works great but it constantly writes to the console at a rate set by the metro object.
The console message I get is ---> bela: bendout _ port: 0, channel: 0, value: -1759 ...

Could this behaviour have a detrimental effect on the bela operations?

Is there a better way to write to the console only when the signal value changes by let say a differential of 1?

sure, just add a [change] object between the multiplication and the bendout object.

lokki

if you also add an [int] object before the [change], all values after the dot will be discarded.

Thanks, I tried your method and it works well in removing the decimals and passing integer only with a differential of 1 but the console was still overwhelmed with the bendout messages. I added a 10hz low pass filter between the [adc ~5] and [snapshot~] and now the amount of message sent to the console is now much better. Here is the new patch if ever someone needs it.

[adc~ 5] <--- analog input # 2 on bela board
I
I [loadbang]
I I
I I
I [metro 50]
I/
I
[lop~ 10] <--- cuts low frequency below 10hz. Eliminates potentiometer noise superimposed on the dc levels
I
[snapshot~]
I
[* -9856.8] <--- brings range values from 0 - 0.831vdc to -8192 - 0
I
[int] <--- strips after decimal values
I
[change] <--- eliminates repeated numbers
I
[bendout]

lokki

perfect! Note (for anyone trying this) that it should be [lop~ 10] not lof...

lokki Again thanks ... I made the correction!

if you want to avoid printing to the console of MIDI messages you can do

[loadbang]

[verbose 0]

[s bela_setMidi]

giuliomoro Great! Another tool in my box 🙂
