Hi All! Can Someone Help me with my Looping Device?
Apr 06 2012 | 4:07 am
Hey guys, I need a bit of help modifying my looping device....
What I want to do is use the selector tool from the waveform~ object to select a portion of audio and somehow get the looper to change speed temporarily for that selected audio as it loops indefinitely. For example, lets say I use the selector tool from the waveform object and highlight a segment starting at 4400ms and ending and 5500ms....for that brief moment in the loop I'd like it to change to a designated speed ONLY for that segment...once the loop exceeds the end of that selected portion (5500ms) I'd like it to change back to a playback speed of 1 until the loop starts over and it hits that selected portion again (starting at 4400ms).
I'm not the best programmer nor very mathematically inclined, and I have tried to the best of my abilities but cannot make it happen!
Here is that patch.

You then scale that value by the overall size of your samples, which you can get using info~ or maybe you have that value elsewher ein your patch already (yes i think, that's entering your [size $1] which goes in your [buffer~ ]). anyway, after that you must have a select or select~ which selects the beginning loop point, then triggers or sends a different playback speed value to your groove~. Another selector, triggered by the loop ending point, which reverts back to original speed. Easy peasy ! ;) more seriously, i hope you'll understand this, can't really see how understandable i am...

You might also need to look into 'ducking' in and out of the looped sample as there will be a certain level of audio clipping at the cut-off points. Look at pong~ and maybe scale~ (if using Max 6). The scope~ object should also help you here on a visual level.: )
