ScaleMaster – a note quantizer & scale database

April 16, 2010 | 10:38 pm

I’ve just uploaded ScaleMaster, which implements a suite of quantizers and a scale database containing a large handful of scales. Hopefully it’s fairly self-explanatory, but ask away, if not.

ace! is this similar to the function of the scaler patch in the max examples? will have a look :)

edit: just playing with it now, this is really helpful, thanks very much :)

Glad you like it.

Could you point me to the scaler patch you mentioned? I couldn’t find it with a quick look.

April 17, 2010 | 10:32 am

it’s in examples/max-tricks/notes-and-pitch

April 17, 2010 | 10:35 am

maybe the_man361 is talking about the Max for Live examples? you can find bits of them in /patches/m4l-patches/Tools resources/M4L.PitchScale.bpatch.maxpat and M4L.PitchModes.txt.

however, chris, can i just say that your scalemaster is like the big daddy, and it is completely awesome, and demonstrates a really musical way of presenting all the logic, and congratulations, and thanks very very much.

the max example referred to here is quite basic; Chris’ patch goes WAY beyond it – big daddy indeed

April 17, 2010 | 5:19 pm

Oh yeah, I remember now… I think I that example has been around for a long time. ScaleMaster goes well beyond that patch. For example, I have gone out of my way to make sure I don’t have any "harmonic mysteries" in ScaleMaster. I used conundrums, instead.

I got some email asking me if there was a good way to limit the scales that are in the scale menu. I do have some plans along this line, but in the mean time, I thought I would show people what the current interface in my Gyre program looks like for scale selection.

Right now the scale selection stuff is too tied to the rest of the program and the block controller I’m using it with, but I do have some plans to try and extricate it.

Hi ive connected / implemented this patch from the pack "NoteQuantize_MIDI_BP" into my project….

im just wondering how i change the scale? is it one of the other patches?

bit of a newcomer to Max… sorry if this is a silly question

Great stuff as always…

I have to ask… any chance of sharing that sweet looking Guitar Mode Viz in your Gyre app? That is Brilliant! How did you ever get that to work? Different colls per string or is it a single matrix with the setting saved?

December 3, 2010 | 6:53 pm

@carltaylor43: the ScaleMaster world is a little easier to use than you’re trying to make it, I think. Attached is your patch with the bottom right section edited.

December 3, 2010 | 6:54 pm

@tohm: Next time I’m mucking about with the Gyre internals I’ll take a look at what it would take to make the Visualizer stand alone.

December 3, 2010 | 8:43 pm

OP, why dont you put the patch here instead of a unecessary download?

December 3, 2010 | 8:47 pm

big big patch, plus we can track number of downloads…?

December 3, 2010 | 10:56 pm

It wouldn’t let me post in-line, fwiw.

December 5, 2010 | 2:10 pm

@ Chris… ah right… so does the ‘p scalemasterdata’ address sub pathes then? do I have to put your ‘scalemaster’ folder’ in a certain place in the max file path?


what to I connect to what? I see the ‘bpatcher’ box is sitting there and the ‘p scalemasterdata’ to the right of it… how to I connect it between my incoming midi data and then send it to the imput of the ‘vst~’

Thanks a lot

using custom scales with midi or with VST plug-ins will not work, at least not
very straightforward and not with every hard- or software but only with a few.
try to use it with custom maxmsp synths, that will work. :)

December 5, 2010 | 6:04 pm

@carltaylor43, If all you plan on using are the quantizers (NoteQuantizeSimple_BP, NoteQuantize_MIDI_BP and NoteQuantizeDegree_BP) only they need to be in your path. The [p scalemasterdata] sub-patcher I added to your patch contains all the data that the quantizers need to work, and it does not need to be directly connected to anything.

The top level patcher [Scale_Master2] has a couple examples in the lower right quadrant.

@Roman: ScaleMaster doesn’t deal with anything other than standard tuning, it just constrains notes to specific note patterns in equal temperament. It will work over MIDI or between a note source and a VST plugin.

oh i havent looked at it as it seems :) well then.

December 6, 2010 | 7:10 pm


thanks Chris… however I still dont understand it :(

Im playing on the keyboard yet, the notes arnt changing????

Ive attached my patch again….


December 6, 2010 | 7:31 pm

Start simply, then once you understand things a little better, you will have better luck adapting Scale_Master to your world. Here’s a pretty simple example:

this thing is great, like all your others, Chris.

thanks for sharing again!

December 7, 2010 | 12:07 am

Thanks for the kind words.

December 7, 2010 | 7:13 pm

im sorry boys I still dont understand how it interacts with note data :(

ive copy and pasted the above patcher and added a vst… i still wont work for me… in fact i cant even get a sound out of it using the above example… heres a pic if anyone fancies helping me?



December 7, 2010 | 8:08 pm

So, I guess it’s time to ask the obvious question: have you gone through the Max/MSP tutorials? It seems that you might be trying to run before you can walk.

Here’s that demo patch with a little more information in it:

also, vst~ instruments, last i checked, don’t take straight note numbers in Max – you need to do some processing to turn them into proper MIDI/VST note events – check out the qs.vstizer abstraction in here:

September 9, 2012 | 3:35 pm

nice icon on the page :)

does this take floats? I recently wrote something like this in javascript to quantize floating point numbers on the MIDI pitch scale to proper integer MIDI notes in particular musical scales – for turning time series data into scores. Could share if anyone’s interested.

i found that using js it was a lot easier to handle this sort of translation than max, even with my dismal js skills!
