Hi,

I'm pretty new to PD, I'm currently trying to make a tape delay.
I've made a very simple one using the delwrite~ and delread~ objects.
I want the final patch to act like an actual tape delay. I'm looking to add saturation and variable tape speed to the patch. I've been investigating using vd~ to create variable tape speed but I'm not really sure how to use it and am a bit stuck. Any suggestions? I've attached the current patch.
Thanks

Technically [vd~] works a lot more like a movable playback head. You'd have to fudge it a little bit to simulate variable tape speed, and I'm not really sure how...

i can't look at your patch right now, but basically [vd~] don't work much different from [delread~]. the signal inlet for the delay time would be the tape position i guess, but i've never worked with an actual tape delay. you just have to make sure that you ramp/smooth it's input signal using [line~] or [lop~ 5] or something. otherwise you'll just get glitches when you modulate it.

Here's one I made on the train earlier (so haven't tested it much).

The idea was to model a tape delay using an array like a piece of tape, with tabread4~ acting as a head(s).

Thanks for the help, the links

Thank you, lead, for the tapedelay patch.

I wonder if there´s any way to

• dynamically resize the table containing tape loop and/or
• only write into and read from the first 1/4, 1/16, 1/64 or 1/256 of it.

Especially the latter option would allow for your patch to mirror the functionality of early digital delay outboard gear, such as a Vestax DDG-1, DDx and alike.

No worries - jayrope, have a look in [pd guts] should be fairly easy to do.

@lead Hi. I am new with PD and your tapedelay is owsome, thanks to share!
