can waveform~display 2 channels in 1 window ?

Dec 15 2012 | 3:58 pm

i built a small looper that uses a 2-channel buffer~. the associated waveform~object displays always only one channel (the left one…). if i have a stereo signal coming from the buffer this is ok. but if i have 2 mono-signals, the one of them (in channel1 of the buffer) is displayed, but the other one (buffer~channel 2) draws just a flat line in waveform~. is there a way to have 2 channels displayed simultaneously in ONE waveform~object or do i have to have one waveform~object for each channel ?
thanks already.

If you open the maxhelp file for the [waveform~] object, you will see there is a tab called "Multi-Channel".

Hope this helps.

thanks for the tip, but i did this already. and what they say is, basically, that you can switch the channel that is displayed in the waveform~object with a certain message. but then it is still only one channel at a time. and following that logic i would have to have 2 waveform~objects to display 2 channels. that is why i was asking if it is possible to have something like a "stereo mode" where you can see 2 channels in one waveform object. or maybe there is another object that would do this ?

Build yourself an abstraction like that: (to be used in presentaion mode)

Here’s another way you might want to try doing this…

You’d still need two waveform~ objects, but…
