ForumsSoftware ← Aalto in Max: how to manipulate filter_cutoff, osc_pitch?

Hi there

I'm sort of directing this question at Mack Fischer who made that great video about running Aalto within Max. My question is relating to the parameters filter_cutoff and osc_pitch. I can't get them to work at all, if I plug any number from Max into Aalto with either of those prefixes, they just move back to their lowest numbers, 20 and 27.5Hz respectively. Any idea how to get these parameters to work in Max?

Thank you.

Heyyy, lo and behold, I accidentally found out how.

Turns out the "filter_cutoff" parameter doesn't respond to "filter_cutoff" prefix, but instead to the prefix "117". Similarly, the "osc_pitch" parameter responds to the prefix "87". So for the filter cutoff parameter I'm running a number box (range 20-20000) into a message with contents "117 $1" and that's going into the vst~ object, and the osc pitch is getting manipulated with a flonum (range 27.5-3520.) into a message with contents "87 $1" into the vst~ object.

I hope that helps some people!

PS I'm using the Audio Unit version of Aalto, not sure if this happens with the VST version.

whenever interacting with aalto in max I have always used 0. - 1. ranges and everything (except two or three pieces for some odd reason) worked perfectly with that out of the gate

If I am remembering correctly the all of the volumes are a bit odd to control under max (instead of 0.-1. it was more like 0.-.43)

I have used outboard modulations in both ways. The first being by textually addressing the parameter I wanted to control (not sure why this didn't work for you) and secondly by using predetermined numbers to associate with parameters.

I may get to my magic trackpad + openmusiclabs repatcher controller for aalto today and this is rpecisely how I do that sort of thing


I'm with pinklemon! Using the parameter number with the AU is the only way Aalto works for me. Max 6.1.6, OS 10.6.8.

Here's a [coll] for all the Aalto 1.4.1 parameters if folks are interested/makes life easier:

Aalto 141 coll

will try to dig up a couple control patches later...

Sorry - here's a patch showing one way to get that coll:

Aalto params coll

edit: hours later, uploaded a better patch, in a .zip

Yeah I think VST input mappings work a little differently to AU, I don't have the VST installed so can't do a test. Still, it's bliss to have an actual smooth, slow pitch and filter ramp/envelope rather than the low-resolution crap that Live and Logic give me!

this is why I love controlling aalto with my touchosc template

blissful smooth OSC data streams

Hey, sorry just saw this message! But to back up what other posters are saying there are a few params that are a little trickier to take over mostly with the VST version, I found more luck modulating the AU version than I have the VST. seems to be more consistency in terms of name/and range for me.

Im using Max 6.1.3 with OSX 10.7.5
