I am building a one shot sampler/ granular type device. For simplicities sake I have chosen play~ as groove is a bit of a faff out of loop mode. I am looking for a fluid resposive way to alter the pitch of the sample being played. You can see from my patch below that I have come up with a clunky annoying way to do it. What I would like is to be able to change the speed/pitch with a dial that smoothly alters the length of the duration of the sample and thus the pitch. I'm sure it's really obvious, but I have a bit of a block about it!

by far the simplest/quickest method would be to use [sfplay~] and its associated "speed $1" message:

Unless you intend to use huge audio files, or want to do granular playback/stretching, sfplay~ is now built for the kind of job you describe. You may also override the "speed" message by sending a signal into the object's right inlet.

. . . getting play~ to operate like this is, of course, also possible, but slightly more of a "faff":

The second example is great! It's actually perfect for another similar sampler I have been working on. I didn't phrase my question very well...I want to be able to change the loop duration part of the message that reads: Start 0. 1000. 1000. Basically I need a max maths type thing that can both multiple and divide the signal in order to transpose it. I don't think i'm being very clear, do you understand what I mean?

I understand your question - dynamically vary the duration of a ramp - and using line~ in this way is problematic; phasor~ is much more flexible in this regard.

OK, what if it wasn't dynamically changed, just able to change the pitch for each sample triggered? The patch I am making is designed for very small one shot samples, so actually saying dynamically is misleading. I just want to be able to change the the third part of a message to play globally to the shots can have some pitch variation. start 0 350 350 start 0 400 280 etc. That way I can introduce more complexity into the patch.

(I usually read OP very quickly, so the misunderstanding is nearly always mine! Although "fluid and responsive" did mislead me a little)

Thanks Brenden!! This isn't the first time you've helped me, I really appreciate the time you take to respond to forums queries - I'm terrible at the operations and math side of Max.

And this is an old patch of mine that makes [phasor~] work a little like [line~] for one-shot ramps, with variable ramp time:
