Hi guys!

I'm a really newbie in PureData and so I would love to could have an help from someone of you.

I wanted to build an interactive/didatic instalation for a few kids.

I want to have a multichannel Wav player (7 channels) each channel will play one instrument from a particular song (piano, drum, vocals, guitar, etc..., till 7)

The trick part is that all the channels should play sync in an infinite loop but should start mute, and only when each kid touches a specific button the channel will unmute. So the kids will be able to listen only one instrument at time, 2 of them, 3, etc, or all if they want.

I would like to have also a start and stop button, to turn on and off all the code.

Can you please help me on this?

Thanks a lot for your time !

@davidborrao Here is a start........ 4ch cart.zip .. it is a 4channel player.
I will post a 7ch player with what you want as soon as possible, and a recorder (for 7 channels so that you can make the 7ch track)......
David..

thanks thanks!

having the tracks in a subfolder "tracks" should they play? is there a play button? Sorry i'm really a begineer on this!

@davidborrao If you already have a 7ch track (wav) made in an audio editor then this should do what you wish............ 7ch cart.zip
The 4ch in the previous post was for discreet channel playback, so on your computer you would only hear the first two tracks.
If you don't have a 7ch file already then post back and I will make a patch to combine 7 tracks into one file, although it will be much later today.......
It will then not matter whether they are the same length........ the new 7ch track will be as long as the longest....... + a bit.
David.

Hi!

Unfortunatelly I dont have a 7ch track (wav), and the best option here will be to have a player patch that can load 7 tracks into it each time I open the patch, and so it will be really easy to change a channel if needed.

what do you think?

@davidborrao Ok. But I am not certain about the sync using the previous method.. Maybe close enough. There is another way to do it.
How long is the longest track likely to be?
Are you using an SSD drive?
David.

Hi!

I think I wrote something good with your last code :), thanks a lot for all your help . Now I need to install Pure data on a Raspberry pi 3, another huge battle, can you help me on that too?

All the best from Portugal

@davidborrao Brilliant!

I have never "installed" Pd on a raspberry Pi.
I have always copied "pd-extended_0.43.4~extended1-1.deb" ...... the "run anywhere" version of extended found here......... http://puredata.info/downloads/pd-extended
to the desktop of the RPI...... and run it that way.......

Having just seen your other post........ I did this with "noobs".......... but on RPI2B.
