Hey guys,

I am building a patch which uses tabread4~. I am playing random parts of a table.
I am getting massive amount of clicks during fast playing this parts.
What is the best way to reduce those clicks between the play of the table parts?
I tried to fade at start and beginning with line~ and tried to use filters.
but all had not real great effect. What do you use? How do you use line or filters?

I personally always use [line~] when trying to avoid clicks. But if you wouldn't mind sharing your patch here it would be easier to see what can be improved.

Cheers!

Yes of cause: mytabread4.pd
You can see some line objects on the right which i used to adjust the volume short before the dac~.
But all were not really cool...

How exactly do you use the line~ where exactly and what values?

Hi,

Your patch is a bit confusing, so please correct me if I am misunderstanding something, ok?

So, [line~] can be used for several things, one of which is to control [tabread4~], other is to control a fader.

If you connect a [line~] just before [tabread4~], then you can send it messages in the form of [a, b c(, where a is the initial index to be read, b the final index and c the time in milliseconds to go from a to b.

Now if you want to fade the sound in between jumps, what you need to do is construct a fader. First of all, you can't jump immediately to the new position, you must delay the bang a little bit so that the signal can be slowly multiplied by a number that goes to 0, and then after the jump, this multiplier has to be brought slowly back to 1. By slowly I mean something like few milliseconds, 40ms for instance.

Below is a working patch that does exactly that, see if you can understand it and let me know if something is not clear. I guess you can then adapt it for your own use:

Untitled-1.pd

Hi,

thanks. Now i understand. Yeah, my patch is a mess. What it does is calculating the values for the line~ object.
But it also gives the opportunity to play a random part of the table.

You line example helps me a lot. Thanks!

I'd personally used phasor~ to read from an array. Simply multiply the ramp by the array range; use the absolute value of noise~ to generate jitter. Sounds like you're verging on something granular. Have a look at this: http://www.pd-tutorial.com/english/ch03s07.html
