problem with MIDI knob controllers

April 14, 2006 | 4:22 pm

Cheers to the beautiful people of cycling.
I am having a problem with knob midi controller. I want to set one controller?s range from 0 to 20000(Hz) but I can?t cause the max. number that my knob sends is 127. Is there a way to do it? And how? (with a comb of two controllers maybe? I don?t know?)
(I know that is a stupid question?I have just started to use Max/MSP)

anyway?thank all of you guys for the help!!!!

Greetings??lstncrflly

hi nihn.
i used scale as you told me and it seems that i am loosing some freq. as i turn the knob.

Is there a way to avoid these!

thank you for your help!

of course you’ll lose some info – midi outputs 127 values. only. so
you scle those to 127 values in between 0. – 20.000

that’s midi.

what could you do??

either a midi encoder ("infinite" knob) or maybe use 2 midi
controllers – one for the rough region the onther one for the fine
tunig – ok, you won’t have 20.000 points (frequencies) but 16.129 –
but it should be ok – if you want to see it differently, you could
have a division down to 154th of a tone… not so bad

if you want more precision, an encoder is the way to go

ok i think I’ll go for the infinite knob or a sensor midi controller!

anyway, thank you for the advice

good luck with your work too.

best wishes

If you want to control frequency the 7-bit resolution is too low
(connectit to a [scale 0 127 20 20000] and listen to the result….)

There is one official 14-bit controler in the Midi world called pitch
bend, still a little low res for the whole range but much better. With
xbendin you can track a pitchwheel.

Elsewise its a question of your hardware, there are knobs which pull out
higher precision controller values composed out of two different (32
appart) controler numbers.

If its a rotary controler you could try my dialin from the abhaXions
collection at cyclings share pages.

And don’t forget to read the… but you know that. Beside the official
ones I’d recommend all of the Max tutors from Peter Elsea , they cover
also Midi problems ()

do not expect from a sensor midi controller more than 127 steps

it’s midi, you know…
