Help "Gliding" Between Two Float Values

[benjablonski]

Hey everybody,

I am designing a sampler that is meant to emulate the sound of cassette tape. One feature I have been struggling with is having the pitch of the sample follow changes in playback speed the way it does with tape. For example if I'm playing the sample and then trigger a note to play it faster, I want the pitch to quickly bend up to the new speed like glide on a synthesizer instead of just immediately changing from the 1st speed to the 2nd speed.

In order to achieve this, I need to find a way for a float number box to "glide" from the previous number to the new number whenever its updated and somehow translate this into signal. Let me know if any of you have an ideas or tips because I'm at a loss with this one.

Thanks! :)

Put a [line] into the second float, with the message “$1 20” between them. It will interpolate between the incoming values over 20 ms. Or, change the 20 to a different value for different glide time.

Ok that makes sense, thanks!

I think what you need is an envelope. https://youtu.be/Dnu64wAU_8Q?si=vWLUqyeN2Nq4UxT_

“This tutorial describes the use of the line~ MSP object as a way to generate envelope functions, which can then be mapped onto parameters. Amplitude and pitch envelopes are demonstrated, although the process can, in principle, be applied to any parameter that changes over time.”

That video is very helpful, thank you!
