Hi,
I attach a simple sampler-sequencer patch. It has two sub-patches, one containing the arrays of sounds and the other for loading the sound-files into the arrays.

1. Is there a way to store the no of samples of each sound? I know how to keep the content of an array (using 'save content') but when I close and reopen the patch, the number of samples is [r filesize] is gone...
2. Is there a shorter way, or more elegant one, to add instruments - other than copying the 'pd sound1' sub-patch and changing some of its arguments?

Thanks a a lot,
ymotion

Hey,
1)Maybe store the sizes in an extra array.. or in a [msg( via "[set(-[ ("

2. you could make an abstraction of it with some creation-arguments..
   ..3) Putting the [mod] inside the counter will avoid glitches with long running time of the patch..

Hi Flipp,
Thanks.

1. fixed!

2. what do you mean by "putting the [mod] inside the counter"? put the [mod] after the [metro] and before [f]x[+ 1]?

3. I thought about abstractions, but I'm not sure how to do it. I mean, I'll still need all the toggles, 16x the number of instruments. If it's not too difficult to explain, I'd be happy to hear how.

Thanks a lot for your time,

Close.., put the [mod] between [f] and [+ 1], then the counter can't run up to infinity..

Abstractions are like subpatches + you can give some variables called "$1, $2, ..." as arguments ..put the variables inside an object (eg. [f $1] ) and connect it with a [loadbang] -to make it load-bang.....
$0 is a unique-per-patch-variable, you can use for table-/array-names etc. ...
So just copy the content of the sub-patch to a new patch and give it some variables instead of the arguments you would otherwise change "by hand". Finally save that patch in the same folder as the "masterpatch"..

Hi,
I think I wasn't very clear in my previous post. I'm familiar with abstractions. For what I know so far, abstractions are a tool to create many instances of reading the same table. But here I have 8 different tables...
I have three arguments in my subpatch: bang1, filesize1, array1 (then 2,3,4, etc..). If I make an abstraction I can rename to , and to , but what about the arrays? If I change the [tabread4~ array1] to [tabread4~ $0-array] what do I do with the 8 actual tables (of the sound-files) that have names array1, array2, etc.? Should I leave them as they are? I though that in abstraction, you should also change the name of the table (to $0-array), otherwise the [tabread4~] would not know how to read it, no?
Hope I'm clear this time.
Thanks a lot,

For what I know so far, abstractions are a tool to create many instances of reading the same table. ...

..If you want them to...
There are several ways: You could put the table inside the abstraction as well. You could give it an unique name, too (with a $0). Or you could give a tablename as one of the abstractions creation-arguments ((you know, eg. the "5" in a [+ 5] or the "tablename" in a [tabread4~ 'tablename'])) via the $1, $2, .. (to keep the table outside the abstraction etc.)

Hi Flipp,
I couldn't figure out how to do the abstraction...if you have some time and you can write down a specific example, even few objects on a patch, that would be really great. I could learn a lot from that.
Thanks a lot.

Hi,

I was also trying to build as simple sequencer as possible. Here is my solution with possibility to store sequence as symbol. Also there are "weighted bangs" used. It means it does not send just bangs, but numbers - could be used for sending notes or different values.

Sequencer strip based on this patch will be part of next release of VisualTracker (http://code.google.com/p/visualtracker/).

Comments appreciated.

Hi Caucasian!
Thanks for posting your reply. Reading your patch, I see that the counter is used to read the values stored in the preset 0$_sequence. I assume that this will be connected to [tabread4~ name] to read the file itself.
I have few questions:

1. what's the use for the [symbol] and [s2l -] objects at the top?
2. I guess that if you want 8-channels sequencer, you'll need to make it an abstraction and then use 8 additional tables as your sound-sources. This is what I find difficult to understand, how to make each abstraction read from a specific table.

by the way, very nice visual interface. How did you make it?
thanks,
ymotion

OK, I managed to do the abstraction. I used the creation-argument as index of tables, and connected it to [makefilename array%d]...
Thanks Flipp, Caucasian and Maelstorm for your inputs.
I attach the patch+abstraction.

to ymotion:

1. [s2l -] "decode" symbol 1-0-1 to list of numbers which I need do real unpacking and sending to toggles. Analogically [l2s -] takes a list of numbers and add "-" between them so the list can be handled as one symbol. I need it for working with storage system further.
2. I hope you have already found out how to work with abstractions... it is essential feature of pd.
3. The visual interface is made by abstraction based on patch attached - I change the colour of toggle according to its value (0/1)

Hi Caucasian,
Yes, I figured out how to construct abstractions (until the next abstraction challenge...)
Thanks for the patch. It's always nice to add some colors
