Max 8 reverse effect ?
Apr 03 2021 | 8:14 pm
Hi, Is it possible to create a patch to listen recorded sounds in reverse effect ? Thanks a lot
- Apr 03 2021 | 9:29 pmsure, you could try the groove~ object's helpfile, the message '-1' there shows how to interface it for reverse playback.
- Apr 05 2021 | 8:18 pmThanks, it looks nice !
- Apr 05 2021 | 8:42 pmOk, I understand, the groove object allows to play samples in reverse playback, but is it possible with audio files ? Thanks a lot
- Apr 05 2021 | 9:15 pmfor exemple is it possible to listen a wav file in reverse effect ? I'm new to Max, I don't understand how to use grove and buffer objects...! Thanks, Regards

I'm new to Max, I don't understand how to use grove and buffer objects...!ah, i understand, no worries then... in that case, i should point you first to the tutorials and docs: https://docs.cycling74.com/max8 but if you want to get straight into sampling, no prob, just go to the MSP tutorials there, and check out sampling tutorial 1: https://docs.cycling74.com/max8/tutorials/07_samplingchapter01to summarize a bit: buffer~ is an object that allocates sample-memory for you, and if you want to play back files, you want to load the file into memory, and then use an object like groove~(or play~ or others) to play it back(there is also a simpler object called sfplay~, no buffer~ required, you could check out its helpfile, but seems reverse playback isn't the most straightforward for me to figure out there, haha... i don't use that object much). to listen to a .wav file from the groove~ helpfile, you could just load the file into buffer~: go into the helpfile, and edit it so that you simply add a message object attached to the buffer~ which reads, "replace"... when you click on that message to send it to buffer~, buffer~ will open up a file-dialog asking you which file to load into it. after that, because the groove~ object in that helpfile is named similarly to the buffer~ object, groove~ will be able to address the memory space that buffer~ is referring to, thus allowing it to read the samples in the file, and when you send groove~ the '-1' it will then play that file in reverse.hope that makes sense and helps, if not, the tutorials linked above is the entry-point for most, but nowadays there are also youtube channels that can help, this dude's channel is one of the best: https://www.youtube.com/user/dude837
- Apr 06 2021 | 8:14 pmno, you can not play files directly from disk reversed. it would theoretically be possible to make a program doing that, but to my knowledge nobody ever did it. playing it reversed after you loaded it into RAM (i.e. into the buffer~ object) is easy though, and there are different ways how to archive this. one way is to use the index~ object, which is perfect if you dont need to change the pitch in addition.

This will create a playlist~ object with your sound file loaded. Connect to an exdac~ object and turn on signal processing. Activate the timestretch attribute/capability. Set the speed value to -1.0.
- Apr 07 2021 | 6:30 am👆there we go! that's the simplest one so far...(and it seems you don't even need the timestretch attribute at all) i should've just given that answer to begin with 😊
- Apr 07 2021 | 6:50 amAh, well, yes. You are correct. timestretching is not needed, nor, technically, looping. Just set the speed to -1. (or any negative value)
- Apr 07 2021 | 7:42 pmThank you very much everybody for these informations ! I try all this ! See you
- Apr 07 2021 | 7:54 pmMarvelous ! It was so simple, but I just didn't know where to begin ! Thanks a lot !
