This must be possible with [rampsmooth] or whatever just dunno how.

Yes, how to do the below without clicking. The [line] isn't really important it's actually dragging in the waveform display without clicking that I'm hoping someone can solve - preferably without externals.

the [trapezoid~] object will give you a windowing function to 'hide' these clicks; use the sync outlet of [groove~]->[trapezoid 0.2 0.8]. Also, your patch seems a tiny tiny bit haphazard (sending two control signals into both loop inlets of [groove~])- look at the helpfile for [waveform~] for some tips.

Hmmm it appears to working. Still a little clicking but I guess you can't "travel through the phone" in realtime properly. Trapezoid... would never have figured that out. Thanks for the tip!

"Haphazard"? You can pack the loopstart and loopend and send it to groove but this should also work.

The essence of your patch was fine; just some tidying up needed done, as in your second example. It was a little remiss of me to criticize a patch without offering some practical advice too, so:

If you are after variable rate playback of a soundfile buffer, with control over 'slice' size and pitch, then most contributors here, or certainly many, would suggest using a [play~]/[phasor~] combination. I'm attaching a zip file containing 4 tutorial patches demonstrating how to achieve click-free nirvana, with [waveform~] gui included!

ps props to Tim Lloyd for explaining the use of [sah~] here.

I just need to scroll/select around in waveform~ without clicking; ignore all the other stuff. The sahgran patch kinda makes sense, it's certainly smooooth. Hopefully this can be done in groove~. Perhaps some sig~ og phasor's outta the waveform and then something something sync-out sah~? Well it HAS to be groove~. This is just an excerpt from something that's working and is very fun to play with and impossible to do with play~.

Impossible? There's an unfamiliar word :)

Drag-scrolling with waveform to [play~] would be the same as with [groove~]. You'll want a fixed loop/slice size and a variable slice start point (send the [mode move] message to [waveform~]). Variable rate playback tools are 'core repertoire' for many Maxers, so there will be many examples on this forum; I'll post a variation of the example above later, but search this forum too.

Relistening to the trapezoid solution and it's actually allright. Found Mesa/elech.tele's site yesterday and now I'm all pro glitch now - don't hear that much clicking on the radio so that can only be good... So thanks again for that "weird" (certainly not obvious to me) solution.

There are numerous variations on the envelope shape too, curves, bells, rectangles.....besides trapezoids

Declicking groove for "timestretching"?
