Patch Advice Please

June 22, 2007 | 4:11 pm

Hi,

I’m doing some volunteer programming work at the moment building a musical instrument for children with mobility disorders. I’ve been given MaxMSP to do the job, but I’ve never used it before and time is running out, so if anyone can help me work it out I would really appreciate it. It should be very simple.

I’m getting a single INT (0-127) from the fiddle object, which is used as the controlling parameter. Depending on whether it is between 0 and 50, 50 and 100, and 100 and 127, it will play a choice of 3 parallel chords. The metronome should also be varied by increase or decrease in the control integer coming out of fiddle.

Thanks for your time. If I’ve posted this in the wrong forum, please advise and I’ll repost.

Kind regards,

Lex

PS: I should add that, while I have done the first 15-20 tutorials, I am not a programmer and am merely doing what I can to learn in my capacity as a volunteer. I have noticed on the forum that there are a lot of students trying to get their schoolwork done by other people, and I hope my request will not be construed as such. Any advice would be helpful.

Hi Lex,

Some additional questions:
What do you want to play chords with? A synthesizer? A sample? MIDI output?
What is the purpose of the metronome and what are the min and max values?
Could you post the patch that you already have?

Cheers,
Mattijs

Thanks guys,

To answer your questions:

1. The metronome is being used to trigger the chords at a faster or slower repetitive rate.

2. Min value 0 – Max Value somewhere around 130.

3. Fiddle is taking a pitch from a GSR2 sensor. At the moment I am using Speedlim to smooth the data, although this may not be the most efficient way.

4. I will use the data to control an FMSynth, or maybe the Operator synth in Ableton Live via Rewire. Ableton is my specialty, which is for some insane reason why they’ve asked me to do this work in Max (??).

How do I post a patch on this forum?

Thanks again,

Lex

Lex, go to your patch, select what you want to post, hit copy, then go to your max post and hit paste. The output will look a bit like this:

#P window setfont "Sans Serif" 9.;
#P window linecount 1;
#P message 79 162 91 196617 this is an example;
#P message 75 88 26 196617 test;
#P fasten 0 0 1 0 80 137 117 119 97 104 97 148 117 136 84 109;
#P window clipboard copycount 2;

Likewise, copy the above text and paste it into a max patch to do the inverse. Yes, it is magic.

Couple of things:

fiddle~ generally will not track pitches below MIDI 48, so you’re not
going to get much out of the 0-50 range. Also, 100-127 is over three
octaves above middle C, so this is probably a little high as well.
(unless I’m misunderstanding; you’re tracking the range of the voice?)

Here’s an example of a way to grab the amplitude (though you could
always use the one coming out of fiddle, but this is a little smoother.

It’s a good thing you did not say you were a uni student,
because we would have given you a lot of grief. ;)

Hi all,

I’ve managed to get my patch working in a basic sort of way, but now I’m having quite a bit of trouble getting my patch to talk to Ableton. The Max patch below should control channel 1 in Ableton via rewire, but it doesn’t want to talk. Any ideas? When I click on ad_rewire in the DSP settings it doesn’t want to move from the Off position, and gives me an error message saying ‘Is Rewire mixer running?’. All the sync options for Max are on in the Ableton preferences.

Thanks,

Lex

Hey man,
I have the same problem.
Did you find an aswer?

Thanx

Yes thanx….I just read it.
But I have these ‘rewire mixer not connected’ problem.
And I read some other things on the forum and it seems that everyone is not crazy about ReWire…so now I’m checking Soundflower which seems to work but I still don’t have a signal in Live….but I’m going on fighting and searching.

Thanx so far
Take care


August 10, 2007 | 8:46 am

Hey Mattijs,
do you still soundflower or did you switch to another device?

Hi jazzisfaction,

I still use soundflower, but without soundflowerbed (because of the increasing latency mentioned before on the forum). Instead of soundflowerbed I use the aggregate device. On a G5, working with Logic, this results in the output getting more and more corrupt with clicks and distortion until after 10 minutes it is almost gone. On Mac Pro there is no problem.

So on the G5 I haven’t found a solution yet, on Mac Pro I use soundflower with an aggregate device and that works perfectly.
