change control changes 0-127 to -24 to +24 integer semitones

alien factory · Post by **alien factory** » Wed Dec 21, 2011 11:58 pm

Hi Max Professionals,

I'm looking for a way to change the control changes from my Kore2 controller which outputs values from 0 to 127 into integer semitone values from -24 to +24 for the tuning of my Phosycon plug-in.

Setup a the moment:

Kore2 knob is midi mapped to the tuning parameter of my Phosycon Plug-in

Result is that the tuning goes linear from -24 to +24 with all the in between values like -12.57 , 11.34, 8.28 , etc.

What I need is something in between that changes the control changes into integer values, so the tuning is always "in tune" with getting integer numbers (-24, -23, -22, -21, -20, -19, -18, -17 etc.)

I hope I could made clear what I mean...

Is there already some max device for this?

I already looked through maxforlive.com but found nothing...

Any help is appreciated...

cheers
Stefan

You may be able to sort this by creating a group containing the plug-in (right click on plugin window header), then mapping the parameter to a macro dial (which is in turn controlled in turn by the Kore 2 knob) , which should allow the 0 -127 range map properly to the -24 - +24 values you require.

thanks for the reply, but thats the way I did this, because I have some more plug-ins afterwards and wanted to save the whole group.

The range is indeed right from -24 to +24, but my problem is that when I turn the knob the values are like I described and not only integer values.

thanks, monolake

now I'll get back to my M4L manual to see how to get this code into a device...

Liebe Grüße

Stefan

okay, Monolake...

Now i build your patch into a max4live midi effect, so i can now control the live dial by a hardware knob and it returns the integer values to a transpose dial (-24 to +24) I added to the device...

But how can these transformed values be delivered to my plug-in respectively my group macro knob, which is connected to the transpose value of the plug-in?

any further help is deeply appreciated..

Stefan

Edit: if I could add "map mode" into the new device that could help??? is this possible?

A little off track but sort of a continuation of what Stefan is looking to do, and Monolake's patch above got me close to my answer- I'm wondering if you can use the scale object contained in Monolake's patch to not just output integer values, but quantize those values even further. Specifically, I'm trying to quantize pitch bend data to only output values according to a certain scale but I can't figure out exactly how

EDIT: basically, I suppose I'm wondering if it's possible to exclude certain values from the integer output

Will do what Stefan asked originally, Towers, have a look at the round object? if not then the route object, with a list of all the values you wish to exclude and connect to the far right output for the values you want....

Hi Darren thanks for the device, but Monolake already posted this and I put it into a device...

see above.. the problem is how to get the "integer" values to the plug-in parameter (tuning).

How can I "map" the output of this device to the parameter "tuning" that I configured in my group, wherein the plug-in sits...??

Hardware Controller knob -> live dial (0-127) -> integer output (-24 to +24) -> ??? -> configured group parameter (tuning)

any help needed?

S4racen · Post by **S4racen** » Fri Dec 23, 2011 12:07 pm

Umm you need the live object model to find the id of the parameter you want to control? Thats kinda the first building block of the 4live bit of Max4Live.... Have a look at the tutorials on max4live.info apologies if this isn't what you mean....

Also look at the built in abstractions for M4L, you'll find one in there that'll do it i'm sure...

Cheers

Awesome- that seems to do the trick...now I need to read up on pitch bend data- I had no idea it wasn't a standard CC. Thanks for your help S4racen

No worries, there a workaround for everything!!

i didn't open the patches, but obviously you need to use "round" object. Or is it "truncate" ?

oops. Also misread the topic. Just woke up, sorry.
