@ddw_music Thanks for that example!

Is there anyway to do this in pd? (8n 8nt 16n 16nt 4n 4nt)

It might be easier to roll your own note player in Pd.

Any example for a simple midi player in Pd?

Is there any transport and tempo object in PD same as in max?

@KMETE Midi objects are part of Pure Data...... it has [makenote] even.

In Max MSP when using Mac/pc the [makenote] object is using the internal sound engine of the computer(?) and therefore playing a sound. do you know if this will be the same with Raspberry pi 2 ?

Thanks you both,
I hav downloaded the Gem library and place it in my search path:

but for some reason I'm getting this error:

I have a max patch that I would like to transfer to pd and to run it on Raspberry pi.

The max patch is playing a video file that is manipulated ( its rate of playing and jumping frames) based on an input from an external mic). in addition to a midi voice that is playing via the internal sound engine of the computer using [makenote] object.

Is the two things above (playing and manipulating video and playing midi sounds) are possible on pd?

What should I look for?

Thanks

where can I found the above object?
I install sexy library but pd can't find the object.

I was wandering if it makes any difference if the audio files will be play from external usb stick rather then from the pi itself ?

the thing behind the thought to use external usb stick is that it will be much easier to change the audio file when needed - just upload and replace new audio files with the same name. so no need to connect the pi to a screen/mouse/keyboard and replace files rather just put new ones on usb stick.

so is that can effect the performance of the patch? (slower reading from stick?)

thanks

edit: the above is not option because when I first power the pi it won't recognize the usb stick fast enough so the pd patch is not "finding" the files. only if I manually restart the patch it is working

Does any one work with this interface and pd /pi combination?

I will get this card only in few days and for the meanwhile I was wondering if:

Does pi / pd will recognize it immediately or do I need to instal drivers?
Will all the 8 output will be available? or do I need to define something in the pd setting?
I'm using this message to setup the interface setting (marked in green):

Thanks!

edit:
If the files I'm playing are exported at 48000/24 bit - do I need to change the sample rate of pd to 48000 instead of the original 44100, right?

What do you man to usr [tabwrite~] in the signal chain? when I write random values into [tabwrite~] that have the same name of the [tabplay~] (with the original audio file) it overwrite it. How can it just add random values in some samples of the buffer ?

I would like to do the following but not sure how to implement that in pd:

An audio file is playing in loop and every time the file is strat from the beginning (or upon some trigger) some random values/samples will written on top of the exiting file. The idea is that it will transform the original audio file to somewhat noisy/clicky audio file over time

how can this be done in pd?

Thanks

@alexandros
I just gave it a try now and it is working just fine using the sf-play2~ object. I'm using [send] and [receive] and see no difference between this and conneting the wires straight to the objects

@jameslo That is sound interesting, but each tracj should be play independently from difference output of the dac

Thanks! will use sfplay2~ then! any difference between using send and receive for starting the instances or between connecting wires?

left and right sides are giving the same results?

for a sound installation I have 10 tracks at the same length that should run in loop. each track is output to a difference output in the sound card.
How can I make sure all track will start at the same time when Pi is turned on?

If I give the message [1) to all the sfplay2~ objects they should all start at the same time? or it might have some delays ?

Thanks

Thanks for all the answers! will try asap all the suggestions when I get back to my pi

So I manage to make that USB audio adapter work!

I still having the issue with the scope~ object.
it is working but looks very strange:

new issue is that my patch toolbar is no access to its close and minimize gun buttons like you usually have in pd:

I got ne Pi3B and have issue with scope~ object as seen in the picture:

another issue I have is that pd is not recognize the usb audio adapter I'm using:

Any idea what could cause those two problems and how can I fix it?

Thanks

I am working on a piece that will turn on and off multiple motors at certain time based on certain variables.
What I'm trying to do is sequence like this:

sequence 1:
button is pressed

motor 1:
start at min 00: random pulse(ON time of 35 ms) every 7 - 10 sec
motor2:
start at min 01: random pulse(ON time of 35 ms) every 5 - 11 sec
motor3:
start at min 04: random pulse(ON time of 35 ms) every 3 - 13 sec
motor4:
start at min 06: random pulse(ON time of 35 ms) every 7 - 10 sec
motor5:
start at min 08: random pulse(ON time of 35 ms) every 5 - 12 sec
motor6:
start at min 10: random pulse(ON time of 35 ms) every 4 - 10 sec
all motors run

when button is pressed again (button count = 2):
sequence 2 starting:

motor 1:
continue random pulse(ON time of 35 ms) every 5 - 10 sec
stop after 01 min
motor 2: continue random pulse(ON time of 35 ms) every 3 - 12 sec
stop after 04 min
motor 3: continue random pulse(ON time of 35 ms) every 7 - 12 sec
stop after 10 min
motor 4: continue random pulse(ON time of 35 ms) every 3 - 8 sec
stop after 16 min
motor 5: continue random pulse(ON time of 35 ms) every 5 - 16 sec
stop after 18 min
motor 6: continue random pulse(ON time of 35 ms) every 7 - 10 sec

-- now only motor 6 is running >> button pressed>> last motor that running(motor 6) is stops.

sequence 3:

all motors pulsing together every 7 seconds for 2 minutes
after 2 minutes elapsed all motor stops.

how can I implements the above in PD?
how is possible to timing events without using metro rather something more accurate?

Thanks

ok it seems I fixed:
