Polyphonic Sequencing for my Sampler

#1

Hey Folks!
Some times ago I made a Sampler with an Axoloti. I can record audio input and play it with a USB Keyboard, chaging pitch, duration and so on. The whole patch has a 3 voice polyphony. Now I want to add a Sequencer to it so that the Sampler is playing on its own. My first Idea was to have a kind of looper for my USB Midi signal, but after some research I have the feeling this is beyond my possibilites. Maybe some of you have a very straight forward answer how to patch something like this?
My second Idea was to add something generative. I tried some things and now I would know how to do it monophonic but I have no Idea how to play a table polyphonic without a Keyboard.

Any hints for me? =)

Best

This is very raw and a basic setup and wont work that well, with out some further additions, but maybe it can give you some ideas to go on from here:

How to turn a simple sequencer polyphonic... without tables?
#3

Cool Thanks! Will try to make something with this. These table thing is pretty interesting =)

#4

Just keep in mind this is just an example patch, you can not copy it one to one, tables are missing you only se the table write and table read here. And some other stuff needs to be added too.

But yes, generally using tables for sequencing is pretty nice :slight_smile:

So here is what I tried. The picture is the polyphonic part of the Sampler. The Patchers "Voices" are Sample Palyers that are beeing played by the Keyboard Object. The Objects on the bottom are the Seqencing part. It is working somehow but not very well. Can anyone tell me how to make this better :D?

This is the whole Patch!

I just tried the Sequencing in a new Patch and just triggering a simple oscillator. It is working well in Mono. It just becomes messy when I make a Polyphonic Patch out of it. It is always triggering the Note "0" together with the notes that I stored.

For some reason I thought that you wanted to use the seauencer for something external, like to trigger a synth.

If you want to make your synth voice polyphonic, there is a lot simpler way of doing so:

  1. Make a subpatch.
  2. Push "edit" button on subpatch.
  3. Go the drop down menu called "view" and select "settings".
  4. Set the drop down menu called "subpatch mode" to polyphonic.
  5. Close the menus and go back to the main patch and push the "update" button on the subpatch.
  6. Now you have a polyphonic subpatchm you can set amount of voice.

To be able to trigger this poly subpatch internally from Axo, you need to use the "midi/intern/note" object:

EDIT:
Oh, after downloading your patch I see you already use the poly idea for the whole structure. Couldn't see that from the picture.

I am not really 100% sure what you are trying to do here, with the sequencers. When you say polyphonic sampler what do you exactly mean? You want to be able to play chords with the sampler? Or.....?

I think it's fairly uncommon to have the sequencers inside the synth voices. But I guess that's the cool part about Axoloti, there is no rules :slight_smile:

I am just not 100% sure what the goal is.

EDIT 2:
Ahhh, so the sequencers inside the voice subpatch are just there to trigger the the 2 table/play pitch individually. I would say that could be done simpler. Something like this, using inv object:

Or maybe you could try making the voices polyphonic too? Although I am not sure if Axoloti can handle poluhonic subpatches inside polyphonic subpatches. You could try it out :slight_smile:

Hey Thanks for your answer! So actually playing the sampler polyphonic with a keyboard is not a problem. I just want to find a way how I can record a sequence of notes so that it is playing on its own, like a loop. I once had an audio looper in the end but that is eating to much performance since I already have 4 table with audio. So I thought just recording the midi notes I am playing would be smart. But the midi/intern/note object could maybe be something. Maybe then the Keyboard and Sequencing part can be outside of the polyphonic patcher?? My ideal would be to record a midi loop like recording a midi clip in Ableton. But recording some notes that are then just triggered by a clock would already be great =) And as I said, the way I did it was working well in a monophonic patch, maybe the sequence part must be outside the polypatch? I also tried something with poly patch in a poly patch but I couldn´t go live with that.

what is the inv object doing?

Edit: Okay thanks for the trick with the inv Object. I replaced the sel object with that and that is saving some performance =) I just use two table play objects because then they are blending into each other when the trigger speed increases and so you can make more grainy pad sounds without hearing the attack so much.

Sounds like a plausible idea :slight_smile:

As I mentioned the sequencer inside the voice subpatch I think will only use extra ram. I would not do that.
