for a long time, i have been using 'cut everything into 16 equal sized chunks and then rearrange them' sample slicers. however, unless you use really even 4/4 loops, the end result never sounds really good.

so today i made a couple of abstractions that let me visually choose which sections of a loop i want to trigger.

the first is [breakpoint-maker], which you can use to line up your sample cut points and create a message box with all your cut-point data.

and then the second is a little player abstraction called [smp-slice] that allows for pitched playback and sequencing of the sample sections.

much nicer and cleaner sample cutting for sure.

(edit - just added a little 5ms envelope to the player to avoid some clicks)

jackull, that's why i added an external pitch input to the player.

add this patch to the sample-slicer folder and see how it works:

wow! that works superbly!!! thanks for the advice boonier.

here is a bonk~ed version. just need to do some stuff with the table storage so that i can insert or delete sections i don't want, and it is good to go i reckon.

honestly never thought bonk~ would work so well for this, but i'm blown away. as long as you use loops with fairly well defined beats, it's great.

sheessh i does work an' all! That is cool

I cant really take credit for the bonk~ idea. It just occured to me that it might be a good application!

Now, I wish the array view was zoomable......

many thanks

I did something with bonk~ a little while ago. Here's what I can remember of what it involved....

Two tables, aSample and aIndex, load a sound into aSample
Play aSample into bonk~ (adjusting params as desired) using tabread4~ and line~. no need to loop.

Each time a 'bonk' occurs: sample the line~ output (to get your 'position' or 'index') using snapshot~
write index value to aIndex with tabwrite(not tabwrite~)
advance a counter at the right inlet of tabwrite object.

To play back slices, use tabread(not tabread~) to get a start(n) position and end(n+1, n+ whatever) position from aIndex, pack them up, and feed them to tabread~. Alternatively: use line~, tabread4~ and some math to make a pitch-variable version.

I'll dig it up or make a new example when I am done playing with my new drumset.

works really well, excellente. thanks again

would be ok on linux or in 0.39 extended, but the gui has gotten even SLOWER in 0.40.3-extended for mac. i think the redraw would take too long to make it really worthwhile. but i'll give it a go today and see how it goes. i have an old zoomable-array patch here i can modify.

It's a very cool patch! Thanks for sharing it!

arse its meant to be quicker in this version. Is that one of Hans's test releases? hmmm there is the [cooled~] object from the unauthorized lib off the top of my head...that does zooming, but i guess its still using tcl/tk

it seems to be absent from the extended package, even though there is help document

I've been having loads of fun with this patch...also really well put together. Would make a good educational patch

no zoom i'm sorry. it was way too much hassle. zooming on the waveform is easy enough to do, but then you have to scale the slice selection and...arrghh, not worth the trouble.

but instead, i added a bit of a nicer envelope, to pretty much stop all clicks; improved and simplified the editing of the bonk-detected slices; added volume control to the slice-player; added a 3-part polyphonic slice player so that you can sequence drumloops or melodies and not cut off the decay of each beat when it finishes;

and just now, i made a nice little drill and bass demo.

hope i'm not pushing my luck attaching a 800kb file to this forum. if it's too much, someone plz let me know. cheers.

Here's my beat-slicer with bonk... beta.

http://www.pdpatchrepo.info/hurleur/bonks_slices.pd

oh cheers. very similar architecture.

'number of slices' is something i should incorporate too.

i have made a similar patch to recgnize slice but i used fiddle~ instead bonk~, so i could detect monophonic note, it was just a proof of concept, first hit target to analyze sound and play to play it quantized ( in fact i play it half tempo )

I was just thinking about doing this the other day, hacking away at the guts of your "pd editor" patch to use for this, looks like you've beaten me to the punch and done it much better than i could have.

Brilliant work mr hardoff.

Hats off Mr Hardoff

I'm quiet new to Pd (using it for 1month now) and i am the happy owner of a 40h kit monome.

Want to do things the OPEN way... so using Pd.
I'm discovering new things everytime i have spare time to hook on Pd.

As a first exercice, i made a beat-composer-with-realtime-slicing for my monome (no ui though, since this was my first project). I succeeded, even if the patches are so awfully bloated that i would be ashamed to put it on this forum. But it does what i want If anyone wants to have a look at it anyway, i might post it in another thread.

Anyway, i wanted to do an MLR-style app to play with my monome.
I didn't know where to start.

Thanks to you Hardoff, i think i might be able to reach my goals, with your slice player and my time and monome interface abstracts...

Thanks very much for sharing...

you're really welcome. i just make this stuff to amuse myself, but it's cool that other people can find a use for it too.

i'll post up a big folder of effects and stuff soon too.
