hi,

you can use the trigger object. it is abbreviated with "t".

if you connect your slider outlet to a [trigger bang float] (= [t b f]) then you have two outlets. the right outlets the float and the left a bang, everytime when a new message comes in. the float is sent before the bang, so you can connect the second outlet with eg. the *~ and the first with the message 44100.

of course you could also multiply the result of your subtraction (endpoint - startpoint) with 2,26757e-005 which is 1/44100 and is even a bit faster in computation than the division.

marius.

Hello list

I am trying to build a live capture and loop sampler in pd.

I have 3 controls - start point, end point and record.

Start point defines the point in the sampled array to start playback, end point defines the point to end playback. Thus I can use sliders to define the limits of a looping sample:

The problem is that every time i move the sliders, i have to retrigger all other numbers in the system to make the sample play back as i'd expect. E.g. if i move the start point slider, I have to click the end point slider then the 44100 message in the above image before it plays back as i want.

I have connected a metro that bangs the sliders and the 44100 message, but this seems like a bad solution...

Can anyone suggest how to update the 44100 message and end point slider automatically?

cheers

matthew
