Hello,

I was wondering if there is some thing(s) to get PD to run along a standard Midi sequencer. Like getting the BPM and play/stop/MMC informations?

One of my objective is create complex and/or evolved Midi controler variation without drawing it within a sequencer window. A simple exemple would be to create an LFO with expon variation of the amplitude with and increasing random flcutuation ... my objective is to inform PD of the sequencer bpm and start/stop moment.

Any suggestion or simply object name?

Hello,

I just found this patch and corresponding abstraction which is a neuron layer for PD. Great, enjoy the power of AI!

See the corresponding papers for details ...

Dear forum~

-(1)- Is there any basic ambisonic decoding patch for PD? Any patch for ambisonic application ... found very old links about this but, they sadly doesn't work.

-(2) - Is it possible to invert a matrix (or even build one) of constants in PD? Like this

A = [ 1 2 3 ]
[ 4 5 6 ]
[ 7 8 9 ]

Many thanks in advances ... have a nice day!

Hello,

About the joystick object, any recommandation about a nice (cheap < 40USD) joystick with lot of buttons? Can the joystick object can see more than one stick (like for the double joystick control)?

Anyone use such a thing for live performance?

Bye!

Hello,

I know well my DSP theory, but I am not deeply familiar with PD.

I just wanted to know how the FIR~ thing works (iemlib). If you know any other possibility for creating a FIR filter, let me know. Is there some objects for IIR filters?

Thank you so much!

I had finally "solved" my problem with a similar method. Using some note on a given channel of a given midi port, I start/stop my sequencer-type PD patchs. It work fine, surely approximative but fine. But you need lot of midi port. I use my pulsar2 4in/4out midi ports between the pci card and the softs to create various links between the software.

This is quoted from a mail passing in the Canadian Electroacoustic Community about three new ambisonic objects for PD. Seems quite well done.

I'm very pleased to announce that new objects for sound spatialization are
available on the CICM web site : [url=http://www.mshparisnord.org/cicm/dl_en.htm ]http://www.mshparisnord.org/cicm/dl_en.htm

These objects are developed by Rémi Mignot and Jean-Baptiste Thiébaut. Most
of them are available for Macintosh, Windows and Linux for Max/MSP and PD.

ambipan~ is an external that uses ambisonic techniques for a surround
panning up to 16 loudspeakers. The ambisonic algorithm is from Michael
Gerzon.

ambicube~is a 3-dimensional version of ambipan~ so you can use it with two
levels of loudspeakers

vbapan~is an external that uses vector based amplitude panning for a
surround panning up to 16 loudspeakers. The vbap algorithl is from Ville
Pulkki.

trajectory is an intuitive abstraction for drawing trajectories. It
contains 8 graphical tools such as ellipse, spiral, broken line, etc.
Trajectories can be stored. The coordinates may be send to ambipan~ and
vbapan~ to localise up to 16 independent sounds.

Help files are written in French for instance, the trajectory help is
bilingual.

Your feedback is welcome !

As I understand (with one minute spent on the yoke pages), midi yoke can be used to route any midi signals from two applications? Like VAC (Virtual Analog Cable) soft/driver for audio streaming? If yes, (and only if yes) that doesn't help me to get the bpm/clock information since I already have some sort of midi yoke application with my sound card (Pulsar II).

I have spent few minutes with [midiclkin] and and just don't get anything. Even if my sequencer is sending everything like : clock, start, stop, position, etc. (I use a midi monitor (visual) to intercept everything passing from my sequencer to PD, and th clock is there!).

But as I see from a hardoff link to the mailing list : midiclkin seems to be under construction ... zut alors!

I would really like to know if [midirealtimein] is giving something effective to someone, somewhere (pulsation or time?) ...

Bye!

The hyperlink still work for me ...

Everything is working fine for my part, even the pdf files.

I am not deeply familiar with neural network, I do understand the principle but I never experienced such DSP my self. My most complex application of "training" is rather simple adaptive DSP : LMS-gradient, leaky adaptation, and some others mostly related to adaptive DSP with linear time-invariant assumed filters, mostly transverse FIR.

So, I know that the author of the paper which I read from la kitchen was at this time using Matlab for the training. In the conclusion, they say that they work and training within PD.

My sole personnal reference on IA is some part of book like : "Signal Processing for Active Control", "Active control of noise and vibration" (from Hansen) and maybay Widrow "Adaptive Signal Processing" or "Adaptive Inverse Control" ...

Even outside PD, training its the biggest challenge ...
