I am working on a patch which randomly (using a metro and a urn-jb) chooses

a different sample out of 10 every so often which will be granularly

synthesized. I am using the play~ object. I am trying to automate

crossfades between the currently playing sample and the just randomly

selected sample (as soon as it is chosen), but I am getting really

frustrutrated with this right now. If anyone could give me some

suggestions, that'd be great. Also, I'd like to give the user 10 toggle

boxes, which would opt certain of the sample in and out of the random

process, is there any easy way to do this? (so for example, only 1, 4, 8,

would be randomally chosen). I can send my patch if need be.

Requires lp.ernie from Litter Pro. Ernie has lots of other 

enhancements over the standard urn object.

Sorry about the alpha channel in the image, I know it's a drag for 

some mail clients, but I can't readily change it on this machine.

This is what I want to do, but is there any way to do this without buying

litter pro?


this is a less elegant solution but i think it does what you need. it uses the radio group instead of toggles

additionally, for your crossfades i think you could use info~ and use the file length to create a time function for your random selection. ie, the crossfades could be a percentage of your file length,. this could also be used to calculate the the time for the next random sample choice, if you get my drift...

I understand the patch example you posted, but I don't have the listfunnel object! is there anything substitutable, i have 4.3 on windows, bear in mind (plus a lot of free externals). Also I'm not really sure what you mean about using info~ as I'm somewhat of a beginner at Max, could you post an example?

Also, I don't think the percentage of the file length would not adequate for crossfading, since considering I'm going to use these files for granular synthesis, only a small bit of each sample will be played anyways (using the line~ object, etc.).

ah, ok. listfunnel is a 4.5 external, but you can use this workaround without much trouble:

also, the efficiency of that info~ method may be curtailed by the the size of file chunk you are using. how small are these chunks typically?

probably something like 100 ms, maybe a little more, maybe a little less...

perhaps you could post/send me this patch. it would be interesting to see exactly what you are trying to implement regarding the crossfade issues.

I don't have my patch offhand, but here's an implementation of the idea you suggested re: the radio buttons, etc. i did have an error when changing the randomness from the sampleness to randomness of buffers as you'll see in the patch. thanks a lot, you're very much help.

ok. a few little fixes to this. it works for me. haven't tackled the xfades as you will see:

xfade version. not sure if it's quite what yr after:

thank you very much for the thorough suggestions, i'm sure this will help
