I've never really found a satisfactory tape delay in Pd so here's a new thing inspired by vintage tape delay machines. Running on MobMuPlat tested on Android smartphone and iPad mini or, of course, desktop.

Time knob from 50-2800 milliseconds.
Feedback knob can be turned all the way to create a loop.
Drive adds a soft overdrive.
Dry/wet is a mix knob.
Smear moves two of the three playheads to non equal positions so that it creates irregularly spaced echoes and it is subtly different each time you turn it on.
Four presets are built into the top four buttons.

@whale-av @Jona Surprise surprise, you were both right. I waited a REALLY long time and the console did print up all the values but it struggled. I set it into a new array and it worked flawlessly - no need to print or see the list, so you have made my problem disappear!
Many thanks indeed,

I'm getting Pd to consistently crash when using [array get] to print contents of even a short - three seconds - audio file. It works fine for simple array information and any handdrawn data. But once I load a file and send it a bang the system crashes. I'm on Pd 0.50, OSX. Is this a known issue?

I'm looking to make (or modify an existing) a simple 3 band EQ - High Pass, Band Pass with adjustable freq and Q and Low Pass. I've trawled around looking at old posts.

Is there a problem with simply dividing an audio source into three and using [hip~], [vcf~], [lop~]? Will that cause complicated phase issues (that I only dimly understand)?

Does such a patch already exist? I'm a strictly vanilla user.

Thanking you all in advance for any tips.

Seán

@whale-av Thanks for your reply - four months later I'm finally getting around to this.

I'm thinking of an effect like the Electro-Harmonix Attack Decay pedal. I used fiddle to detect note onset (maybe threshold is cheaper CPU-wise though?).

This patch can get me some of the way to making a piano swell etc. If anyone has anything to add, I'm all ears!

Thanks,
Seán

You're welcome!
The iPad version looks like this:

A six-tap delay with independent control (per tap) of feedback, delay time, pitch, direction, and filter frequency. Loosely based on Rainmaker eurorack module by Intellijel, but I soon deviated to my own musical preferences. Enjoy!

I'm looking to live process a piano (for instance) and being able to change the attack time of each note. I'm not expecting to be able to do this without latency or delay. No idea where to start though, all the envelope shaping information I can find relates to synthesis and not real time mic input.
I'm a strictly vanilla user!

@Balwyn That's super, works perfectly (and looks real pretty too!). I appreciate the help, I would have spent years trying to work that out.

Thanks for that Balwyn,
Yes this works perfectly and I don't need to know which toggles were on only that they are all off. However in "real life" I need a version with nine toggles. So I expanded your example (perhaps incorrectly!) and it doesn't work consistently with nine.
Any idea why?
ninetoggles.pd

This little thing is evading me:
If I have three toggles how do I calculate if each and all of them are turned off?
I thought [int] would do it, but no!

Turns out the out of memory error was trying to tell me something after all. Once I fixed the resize issue the whole patch works - thanks a million.

I'll share it here if it's helpful for anyone: a sound-on-sound looper with adjustable loop length and the ability to pause loop to restart it from beginning of the table.

Seán.
monoloop4.pd

Oops, yes you're right, I got the maths wrong with the resizing! The toggle isn't supposed to clear the loop as I need to be able stop loops and restart the extant loop. The mystery for me I think is why [tabwrite~] doesn't write fully into the table.
Thanks!

Hi Balwyn,

Your patch was super helpful thank you! I added a function that determines the loop length and figured everything was working - alas, it's not!
e.g. After clearing a short loop, the next loop recorded retains the previous loop's length but I don't understand why.
For this patch I need to be able to start the loop from its true starting point (not a continuous tape-loop style of cycle).
Thanks again!

monoloop3.pd

Hello all,
Trying to do what should (and must be!) the simplest of things: Hacking Fernando Quirós' monolooper to include overdub.
The problem starts when I attempt to create a new layer in [tabwrite~]. This new layer also needs to include whatever is playing in [tabread~] i.e. the loops before it. How do I include the new audio signal without disrupting the original loop structure?
MonoLooperOverdub.pd

Much appreciated.

@whale-av Thanks for that David, but looks like I'll use tables instead as [delread~] still doesn't start from the beginning point of a recently recorded loop, it just cycles around and I can't find out how to tell it to play from sample 0 of the buffer.

@whale-av Thanks for the reply David. I now realise how unclear my question was! In simpler terms I am looking to stop hearing a looped delay line but being able to start the loop again from its start point.
[switch~] doesn't start audio from delread~ from the starting point of the loop for me here. I can't find any mention of being able to use [delread~] in this way.
DelayLoopStart.pd

Is there a way to start a delay line using delwrite~ & delread~ from the beginning of a buffer? When using a delay line as a loop (feedback = 1) I am trying to fade out a loop and then building a function whereby I can start the loop again from its start point.
Is this possible without resorting to tables?
Thanks!

@whale-av Thanks for this. I already checked the localhost so checked that again. All is as default. I deleted saved state folder and it makes no difference. I also emptied saved state folder and made it read only so Pd can't write in there. But no dice!
But I'm not giving up yet!
