Tune-able synth needs help
Hi all,
I have talked my way into a tough college assignment _
what i want to achieve from my patch is .....
--to be able to tune or detune individual notes on my midi controller and
---have pre defined temperaments for available for selection.....
----that can be tweaked and save a user defined temperaments.

i have set up a patch where i can manipulate the tuning of the note in and/or the freq output from the controller
but once these are changed for one note they change for all notes ....
i want make changes to each discrete note ie slightly tune up A and slightly tune down B

anyone have some examples they could share ??

Hi and welcome to this forum,

If you are synthesizing the sounds using Pd and the keyboard only activates them, that is not difficult to do. If you are using Pd just to handle MIDI and this MIDI data is then sent to another synth which produces sound, then you have a bigger problem in yours hands: pitch bending in MIDI affects a whole channel, meaning that all notes in a channel will be affected by it. The solution I did once was to route the notes according to their pitch classes, so that every C becomes channel 1, every C sharp becomes channel 2, etc.

Take care,
Gilberto

Hi Gilberto,

thanks for the suggestion ,

yes i am going to keep this contained in PD extended for now (not using another synth just going to use simple osc~ and add harmonics as per patch above ) and try to transfer over to vinilla later to see if i can create a standalone app, (have been warned some object may need to be tweaked upon transfer)

'route the notes according to their pitch classes' sounds like a possible solution do you have any examples of how this might be achieved ?

Hi Willi,

do you have any examples of how this might be achieved ?

Yes, here is a simple example:

So now you can use these velocities to activate something. You could also use a [select] instead of that [route] in case you want a simple bang once a pitch class is identified:

Hope this helps. Cheers,
Gilberto

excellent work thanks for this ,

My pleasure.

Hi all have come across a small problem with my poly patch and was wondering if you could review to see if you can spot the error .

every time i play a key it sound on the first touch and then is silent for the the next 3 touches and will then sound on the next rond again .
i believe this pattern of the first of 4 beats is because i,n trying to set up a 4 voice poly ? any thoughts

just noticed upon ensureing i had the right patch to share with you that now there are also some clicks and delays after being introduced ?are these happening for you why would they occur as it worked fine yesterday?

Hi WilliJ,

I spotted the problem, it is inside your subptaches [pd vocie]. Although all four have the same name, you didn't copy and paste them but actually you created them individually, right? Because the first one is correct an the last three are not: the [vline~] should be connected to the rightmost inlet of [*~] and not to the [outlet~]. Just correct that and you should be good to go.

Cheers,
Gilberto

@gsagostinho wow what a blunder - maybe i need more regular breaks
\thanks Gilberto

what a blunder

Happens to the best of us
