Delay & Feedback

September 16, 2007 | 6:06 pm

I’m creating a simple [tapin~] / [tapout~] system, with feedback possibilities.

I’d like to control the feedback volume according to the number of repetitions it will create.

In other words, I’d like to know the feedback volume needed to make 1 repetition, 2 repetitions, 3 repetitions.

The maths doesn’t work like that. If you have feedback > 0, you have
an infinite number of repetitions. End of.

If you want a discrete number of echoes, you’re better off putting
multiple explicit taps into the delay.

It’s a nice idea but it would be too CPU intensive and I don’t really want this to be precise.
After few experiences, I think I’ll use this to control the feedback amount.

there is also [tapout 0. 0. 0. 0. 0. 0. 0. 0. 0. 0] – not everyone knows about that because the help file is quiet about it.

whoa! i didn’t know about that!

crap roman how do you find these things out???


September 17, 2007 | 3:03 pm

Probably by reading the f m.
As someone much wiser than myself here once told me (probably Peter C.), don’t rely on the .help files alone. There’s often more to be found in the reference manual (and sometimes even more surprises when you ctrl-alt-click on an object to see what messages it understands),
cheers

that’s the first thing new devotees of the 110 cult learn at their
initiation. I tried, but it was too bloody…

or he just read it in the reference manual!

MSP46ReferenceManual.pdf, page 414

but also already in MSP doc rev1.1 (1998), page 281

And it’s also written in the tapout.help file.

i was sure that you (in opposite to jb) really didnt know it.

the help file says something like "you can enter as much as delay times accoring to the number of outlets you want".
that is a very cryptic way of saying "tapout can have up to 64 arguments."

i read that for the first time in my life last night. luckily i know how to use the trial and error method very well. :)

more info about why it is the biggest error in academic sciences today that people use a solution for a problem once found over and over again (like looking in help files) – instead of finding new ways of problem solving on a daily basis can be found the source code of microsoft office and in books by philosophs like luebbe.
