Hello everyone,

I am very new to PD but I am trying to build a microtonal polyphonic synthesizer where one can modulate the pitch of each of the 12 semitones in the chromatic scale individually, similar to what was possible on the old Korg PS-3100/3300 (why don't they do that anymore??). Here is the patch so far (using float in the example):

Polyphonic Microtonal Synth.pd

My problem is in getting each midi note seperated to each oscillator for pitch modulation. I used (select) and then the midi note numbers for C, C#, D, etc. to seperate the notes to each oscillator but then (select) sends bang, not the note number pressed, and I had it connected to a (mtof) object but of course it does not work. Using (float) also does not work well because it stores the previous pressed value (see example patch above).

How can I select/filter a given note out of the chromatic scale and then have it passed on onto the oscillator for individual pitch modulation? Pardon my ignorance but I already tried several things without success

Thank you!

Tom, if you are running a Debian based distribution, you can simply download the .deb package from that link I sent you. But if you want to compile it, you will get some of the newer features. Also, if you have pd-extended installed in the same computer, you will have to force the installation of that .deb package. Let me know about it so I can give you the details.

Take care,
Gilberto

im using arch-linux and i feared it would break the build process without the libsndobj-cvs ´, but in this second the build completed.. but thanks for the quick respond and help offer

@tomchaossen No problems. And just one more thing to keep in mind: Pd-l2Ork has broken binary compatibility with pd-extended and vanilla. This means that some externals will not work properly on it (but there is a way of compiling them for pd-l2ork, although I never tried it myself). That is by far the worse limitation of it. But if you work mainly with the externals that comes in pd-extended (all of which are included - and some improved! - in pd-l2ork) then there is no loss at all.

EDIT: I myself use it 99% of the time, it's only when I need to use the HOA library that I turn back to pd-extended or vanilla. But as soon as I manage to compile it for pd-l2ork, then I guess there is no turning back for me

one or two externals i would like to compile like the great tabletool, but i think i will get them working somehow, btw, wow...the gui looks nice

and in the worst case i can use them in normal pd and send the resulting tables over to pd-lork with some send options

@tomchaossen Please let me know if you manage to compile them, I have very little experience compiling externals and I would appreciate some guidance. The GUI is really nice, and a lot of the annoying bugs (or "features") found in extended were solved: you have infinite undos, you can connect multiple cables to objects, you can hold shift to keep connecting cords from a same outlet, you have a better tidy up algorithm, you can bring objects up and down in their layers (so no more deleting and pasting and losing connections when something has to be above something else), you can use the home and end keys in your keyboard while typing, autopatch is automatically on, and the list goes on and on. On top of it all, the developers are very active and friendly, and they have already fixed a ton of stuff that I found problematic. Really amazing stuff.

i will try to build some externals and send you an makefile which is working, if i dont get it working this night i got some well studied friends which can hopefully make it work =)

@tomchaossen thanks a lot, I really appreciate it. And well, for sure we can also contact their mailing list and they would help us, but I fear I overspammed them today with tons of random ideas and bug reports But I can give it a day and then knock on their door once again.

To maintain your value after a routing is very easy in Pd. Just use the route object and then repeat the value before route.

@pulsed That's very witty indeed

Why is that funny

@pulsed Funny? I said witty, meaning clever. I think you misunderstood me.

EDIT: I am no native speaker of English, and I just found out that the most common use of witty is to mean a funny remark. That said, I also found wit defined as:

understanding, intelligence, or sagacity; astuteness.
Synonyms: wisdom, sense, mind.
'
So it was a compliment

Aha ok. And thank you!
