I'm using [pix_record] to record regular video. But, I also want to record the Gem objects I have put into the same gemwin on top of the video. Any ideas?

I'm trying to set up a patch to have a midi controller trigger specific bangs within the patch. Before I go about buying a MIDI controller, I thought I'd look for a MIDI controller emulator in order to test the use of it. I know all MIDI controllers are not the same, but I figured an emulator would be better than nothing.

I did a few google searches for MIDI emulators for Mac OS X but didn't find much. I found one Monome emulator, but that requires MAX/MSP in order to run.

Any one have any ideas?

Thanks in advance.

I'm trying to make a pretty simple "if" kind of thing.
I've been using [moses] to split a signal of data under and above a certain number. After that all I want it to do is to send a specific number out. Here's a diagram:

incoming signal
|
|
[moses (n)]
/ \
/ \
/ \
send "0" send "1"

I realize this is probably extremely simple. But I just can't seem to find the right message to use. I tried print, but that didn't seem to work.

If there is a better way to do this without [moses], please tell me. Basically I am just using [moses] to send bangs to these messages.

I want to be able to pull a specific frequency-band out of a track, like 400hz-1000hz, in order to manipulate it. I tried using [bp] and [line] but I can't get those to work. Of course it should be known that I'm very new to PD.

I think you can do this with [pix_snap2tex], it takes a snapshot of the current render buffer, and then you can use [pix_record]

Have fun!

Sorry to keep asking things, but could you give me a simple diagram of how this would work?

Is it this?:

[pix_texture]
|
|
[rectangle]
|
|
[pix_snap2tex]
|
|
[pix_record]

I read the help file on [pix_snap2tex], but am still having a hard time.

Thanks. I'll try these ideas out and report back.

I'm running 10.5.8 with PD Ex 0.41.4 and haven't had many issues. I've played video with it too. Not exactly sure what GL is. What are some of the specific issues you're having?

Weird problem. I don't really know exactly what to do, so I'll just suggest a few things. Try restarting your computer. Try moving the .dmg file out of the download file. Try quitting Safari.

Good luck.

One hardware option would be to use a mixer. That way you can run just one input into your computer.

edit: although if you really need to differentiate between the two signals, then my suggestion is not much help.

Well I'm looking at the readme.rtf in the .zip Shankar linked to and am already confused.

2. enter the name of the app you wish to communicate with in the app_chooser box (e.g. life, mlr, box). This gets inserted in transmitted OSC messages, and is used to choose which OSC messages to act upon.

3. startup the app (e.g. life, mlr, 64 step)

The app_chooser box just looks like a comment above a number box. I can't click on it, or edit it.

Thanks, flo.

Don't use 'auto $1.' make an integer counter, bang it with a metro, and send that output to the right inlet of [pix_film]. Counters usually look like this;

[X]
|
[metro 20]
|
[int 0]X[+ 1] (outlet of [+ 1] into right inlet of int)
|
[mod n] (replace n with however many frames you want to loop)
|
v

I gave this a try. But I can't seem to figure out how to make it control the speed of a video. I can only get it to loop the beginning of the video.

edit: I've attached the patch I'm trying

Just be careful with the repetitive output. Each time it sends a new number that is less than 8 (for example) [>8] will output a 0. Each time it sends a new number that is greater it will output 1.
A lot of people use the [change] object to filter the repetitions. It only lets through a new value, so 0 0 0 0 1 0 0 1 gets filtered to 0 1 0 1.

Yeah. After I thought about it for a bit, I realized this would still happen with [>n]. Thanks. I'll try out [change].

@toxonic said:

what about the compare objects? [> 8] for example sends out a 1 if the number at the inlet is bigger than 8 and sends out a 0 if it's small or equal 8.

Awesome. Thanks!

Thanks for the informative response, PonZo. You've given me a lot to try out and think about.

No, I don't want to "extract voices from a mix."

I was thinking more of having a sample being split up into different frequency bands (1-399, 400-1000, 1001-5000, etc.) They don't specifically have to be those ones, but you get the idea.

As I said--I am very new with PD and am still learning things. So although I used [bp], I probably wasn't knowledgeable enough to use it as creatively as you have described above.

I do have PD Extended, so I'll keep reading the documentation, which has been pretty easy to follow.
