Time-line editor (for midi or other), and PV-spectral filter with freely settable bins

[Iannis Zannos-2]

Hello,

I am looking for the following 2 tools:
1. A time-line editor that can be used to store timed numeric values on a track and play them back (for example as MIDI messages sent to control other software).

2. A PV FFT UGen that permits one to filter audio input (for example white noise) by the spectrum specified by an array of values in a buffer, where each buffer is a bin representing the amplitude at a specific frequency of the FFT;

Would be grateful for hints to any related libraries or classes.

Iannis Zannos

Hey Iannis,

You can do 2. just with PV_MagMul.

//use as table

well, I do have a MIDI file implementation in my lib, which also has  
a plot function with a timeline view. Only it doesn't play yet.  
Shouldn't be too hard to make it play though, with a few simple Tasks  
or maybe a conversion to a pattern. There is also a MIDIEventRecorder  
class which can record timed events for use in SimpleMIDIFile  
(undocumented unfortunately).

Look at SimpleMIDIFile in wslib ( Quarks.install("wslib") ).

cheers,
Wouter

I am currently working on a timeline function executer, with a gui for
entering the functions and sliding them about in a score.  This can
evaluate a function at given time. Not finished yet, however. May be a
bit yet. It will also have  printing function for printing out scores on
paper, in which the function definitions are printed on paper as part of
the score. Most likely it will output pdf or the like, but I haven't
decided yet.

Iannis,
i've been developing a multitracker for a while now:
it's pretty open for all sort of things:
soundfiles, functions, files, patterns, events
a current snapshot is at:
< http://www.sampleAndHold.org/spool/teaLips_20080505.zip >
This lib is still under heavy development, but most things work and  
the gui is cross-platform. And the help-file is outdated.
You can do a:

MultiTracker.new.gui;

and select "textFiles" on the right. there you can open some text  
files with code and place them (using enter) on the timeline.
Contact me off-list for more info.


Best,
Jan

hi all,
for bin scaling there's also pvcollect (which seems nice and intuitive to me)
scott, dan, is there a performance difference between PV_MagMul and pvcollect?

grtz

b = Buffer.alloc(s, 1024, 1);
d = Buffer.alloc(s, 1024, 1).setn(0, 0!1024);
w = GUI.window.new("~", Rect(0, 200, 1024, 150)).front;
m = GUI.multiSliderView.new(w, Rect(0, 0, 1024, 150))
    .value_(0!512)
    .gap_(0)
    .thumbSize_(2)
    .valueThumbSize_(2)
    .action_({|me| d.set(me.index, me.value[me.index])});

    chain = FFT(b.bufnum, in);
    chain = chain.pvcollect(b.numFrames, {|mag, phase, index|

great jan! looking forward to try it!
but i get an error:

MultiTracker.new.gui;

a MultiTrackTools: a MultiTrackObjectEditor

Yes, a pretty big difference. pvcollect will typically use more CPU
than an equivalent PV_MagMul, in part because it creates a whole
little mesh of UGens rather than being a single UGen. It can do more
things though, so that's the tradeoff.

thnx for clarifying, dan.
i just found the efficiency note in the help file :)
