Just a quick question about delay

December 29, 2012 | 12:59 pm

I’m following the absolute basic delay tutorial, and instead of using ‘adc~’ as the audio input, i’m using a ‘buffer~’ object and for some reason i’m not getting any signal.

I’m really new to max/msp and still getting used to everything, but any guidance would be very helpful, thanks a lot.

p.s. there is a part of the patch that isn’t copy and pasted which is just an audio loop being connected via ‘buffer~’ and the waveform shows and plays normally in the rest of the patch, just not when it is being run through the delay.

hey. In the patch you posted, there’s no buffer the grrove object can refer to.
The groove object needs a signal input for playback speed. It also needs the message "startloop" and "loop 1" if you want it to loop.
The delay part seems ok to me. Meter~ for example is your friend if you want to check where in the signal flow is your mistake and you don’t get any signal.
Also there is under "debug" the point "probing". If you switch that on and pointy on a signal patchchord with the cursor, you get some level metering, so you can also see…
Hope that helps.

Well, one basic problem with the portion you posted is that there’s no buffer called ‘audio’ in the patch. Groove plays the buffer object that it is associated with, and without the buffer, the groove has nothing to play.

cheers my friend! i managed to get the delay to turn on and off when i want to as well, one last super quick question then, wha does the ‘sig~’ object do and why was it needed?

again, thanks for the help!

[sig~] tells the [groove~] object how fast to play back the sample. Try attaching a [flonum] to the [sig~] object and see how this changes the sound of the sample. Try checking out the help file for [groove~].
