hi,

i'm looking for a software which can do the following:

1. recieve parameters from a python script, for example number of tracks, vst instruments

2. do a algorithmic composition using the parameters recieved from python

3. play the composition with the vst instruments setv by the python script

can i do this w pure data?

thanks a lot

cheers

chris

@emens 1. https://guitarextended.wordpress.com/2012/11/03/make-python-and-pure-data-communicate-on-the-raspberry-pi/

2. Yes.
3. Yes. The vst instruments can be CHOSEN...... a decision as to which one you want to control. But the objects [vst~ myplugin] will need to match the vst executable (32/64bit) and the Pd version bits and the os. I know that it works for 32bit.
   [vst~plugin] has been built for 64bit........ https://forum.pdpatchrepo.info/topic/11953/vstplugin-v0-1-0-released
   You will need [vst~_help] for the 32-bit [vst~]....... https://forum.pdpatchrepo.info/topic/9319/how-to-use-vst-object/2
   You should look at this........ https://forum.pdpatchrepo.info/topic/11096/making-an-audio-vst-for-raspberry-pi
   This...... https://forum.pdpatchrepo.info/topic/11605/loading-3rd-party-plug-in-problems
   You can open (SET) just the vst that you name in python but you will need to understand dynamic patching for that........ unless the new [vst~plugin] can call different vst's.

Not sure what you want to achieve. Some want to use Python to create pretty graphics, but the vst plugins already are much prettier than anything you can easily create in Pd.
If you want to save and recall presets then you can do that in Pd.

oh thanks a lot,
my goal is to automate the way i build tracks and let as many parameters as possible be controlled by controlled propabilities without losing the character the tracks would have when they were completely made by my own decisions.
so in automating the decisions about, tracks, instruments, bpm, length, chord changes, breaks, which vst pugin i could speed up my workflow
at the moment i have a python program which generates all the parameters of a song, but it leaves me with a txt printout which i have to follow then by hand in my daw. even the overall composition algorithms are sketched by my python program.
what i liked to achieve in far future would be to fill the gap between the construction made by my python program and the actual audio output. automate everything and still maintaining the style of my personal tracks.
so what i need to find is the connection between my python parameters and the vsts which play the song in the end,

@emens You should post some samples of the messages that Python generates.
Is it a single message dump, or are messages generated in time?
David.

at the moment its a single message dump - its only a txt file containing all parameters in human readable format so that i can follow the instructions and build everything by hand in my daw.
there are informations about: number of tracks, bpm, chord scheme, chord changes, time signature, track length
for each track: vst instrument, variation patterns, fx lanes, event densities, also composition methods or composition tools to use, fills, drops oddities, even from which mp3 source the sampler has to pick its samples.
so only the abstract macro plan is done by my python program at the moment. i'd like to bring everything a step further in future and even let the rest be done automatically.

@emens You will not need to make python talk to Pd then.
Pd can simply read the text file produced by Python.
But.
It will be simplest if the file is broken up by commas...... and carriage returns are avoided at all costs.
useful.pd
The messages can then be routed in Pd.
David.

@whale-av wow, thanks a lot!
