Thanks Wcalvert, that helped a lot! You have been very generous with your time and I cant thank you enough. Happy Holidays!

Thats a good point. I thought I went a bit overboard, lol. Thanks for your addition, I will definitely slim down the comments.

Hey Wcalvert! I hope all is well with you, brother. I am in the process of commenting the crap out of my code, 1. So I can understand it better and 2. For future users to get as much as possible out...

Keeping tight lipped Wcalvert? lol

lol those supersaws are amazing! I think this is right now, again Wcalvert saves the day!

I added the code to only execute detune when the knob is turned. Onwards and upwards!

Next is LFO, a...

Yes, I think thats the traditional direction, no?

Sweet! Just one thing... it seems to be uptuning... any idea's on how to reverse it? lol

I was HELPFUL! lol

So I tried this:




float cents = 100 * analogRead(A17) / 1023;
float detune = pow(2, (cents / 1200));
for (int i = 0; i < NUM_VOICES; i++) {

So I think the problem was I set detune as an integer so it was rounding to one, setting it as a float fixed that. Here's the updated code. Next I'll be working on making the detune sweeepable while...

Thanks Wcalvert! I think I implemented it right... but I'm getting a value of 1 for detune even when I turn the pot... I need to keep tweaking here I guess.

GOT IT! Somehow the envelopes in the Audio Design tool got misnumbered when I added 32 voices... some envelopes were numbered with the wrong oscillators. You can see what I mean if you import the...

Strangely if I play the notes one after another another slowly, this issue doesn't occur. Only if I play one note after another relatively quickly.

Hey everyone, hope all are enjoying their holiday season!

So I upped the number of voices to 32, and added an attack and release knob for the envelope!

I am running into a few strange issues...

Ahhh sweet I get it. Thank you sir!

So you can call numbers instead of the full WAVEFORM_SINE? And the compiler knows when you map WAVEFORM_SINE to WAVEFORM_TRIANGLE you mean 0 through 3 as well? I wasn't aware of that.

Just FYI on a windows machine with python 3.6 I had to run ' python -m http.server 8000 ' on the AudioTool directory and then I had access to localhost:8000, the other command threw an error. I may...

Now you've really got me wondering... what voices are using that are so cpu hungry?

I was thinking 4 different waveforms, WAVEFORM_SINE, WAVEFORM_SQUARE, WAVEFORM_TRIANGLE, WAVEFORM_SAWTOOTH, I think they are the most
"musical of waveforms. Is that doable?

Man I thought I was cutting edge here...lol. I feel like an uber n00b...haha.

Just one last thing wcalvert, the waveform selection thing...

That sounds awesome but my only real C++ experience is super limited to this teensy stuff. :/

OH and what does 7f mean? lol


sgtl5000_1.volume(.7f);

WOW!!! Thanks so much wcalvert!!! I added in my USBHost code, the 8 buttons, and the lowpass filter. There's a lot to go through here otherwise, thanks so much! A few quick questions...

What would...

Thats fantastic man. When you're ready to share it I'd love to check it out! I'm sure a man of your skills is putting together an amazing product! And I love the op-1, btw... lol. Now you have me...

Wcalvert, Out of curiosity, how many oscillators per voice are using on your synth? And what is the purpose of all the encoders?

Yes I always figured the way I wired it up may not be ideal, this is my first ever stab at a synth and my coding AND synthesizer skills are limited at best, though so far I think I've muddled through...

So I'm trying to set up your code wcalvert and at first I noticed that the pot was only selecting between two waveforms, and it looked like you had it mapped that way so I changed the mapping to...

Thanks wcalvert and neurofun! I think I get it now. And yes wcalvert myI'm using knob1(a16) for the first 16 waveforms and knob2(a17) for the last 16. Thanks again man, you are a lifesaver! I don't...

After some research it seems pointers may be way the way to do this but I am pretty confused on how to implement them.

Hey everyone. Here is the new version of my synth code. I am having some problems figuring out how to pass current potentiometer values to the onNoteOn() function. My solution to change the waveform...

Anytime, and I mean anytim e at all you need a musicians perspective or you need someone to test out something you are working feel free to send it my way, I am honored I could help!

"Thank you" isn't even close to a strong enough phrase at this point. That one addition made the synth beautifully, perfectly playable! A million times, thank you so much! Now I'm off to add on my...

First of all thanks again wcalvert you have been a godsend! I still am having a bit of a problem that I cant understand fully. So lets say I play a chord with my left hand ... 2 or three notes, lets...

Also maybe instead of freeing up the note when it totally finished there is some way to test if a note is in the release phase of its envelope... maybe I'm overthinking this.

I have to really study the code to figure out exactly how its working as I'm still not 100% sure what wcalverts contribution is doing exactly. I appreciate your advice tele_player I'm just having...

So I implemented the envelope pots today (for attack and release) and I'm running into a problem I think is related to the inability of this system to voice steal that I need help with. When I turn...

Thanks wcalvert! Like this? Quick question, I first tried putting those lines in setup(); and it didn't work until I moved them outside of the loop and setup functions. Is that a scope thing? Thanks...

Tonight's edition of the Panda Synth is the synth with working test buttons using oddson's super clean and awesome idea. Also filter and reverb have been implemented.

Yup, that's on my todo list too. Two oscillators per voice (detune-able) and a noise source as well. I also want to add separate ADSR controls for each oscillator. And the buttons on the unit itself...

Saw a couple errant connections and made a couple small tweaks to the SynthArch code.



#ifndef _SYNTHARCH_H
#define _SYNTHARCH_H

#include <Arduino.h>
#include <Bounce.h>
#include <Audio.h>

OK Got it working! Here's the basic USB Host engine, now I have to work backwards and add each feature from the other version in. Thanks again to wcalvert and oddson, I couldn't have done it without...

Actually I do have one last question. I always thought an if statement needed a condition... like if something = something then...



if(idleVoices[i]) {
idleVoices[i] = false;
...

Got it! Thanks so much wcalvert! When I get home from work I'm going to implement all this then post when I get the whole thing working. Bt the way I am musician first and a pretty new coder second...

Thanks so muich! One last thing, what exactly is idleCheck? Is that a built in function? Sorry to bombard you my friend, I am very hungry for knowledge in this area. :)

Also am I wrong or should this



if(voiceNote[i] == note) {
envelopes[i]->noteOff();
voiceToNote[i] = -1;


be this:

Thanks wcalvert! Two questions when you have a moment, I dont quite understand what the arrays with the 1's and -1's are doing...



bool idleVoices[12] = {1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 };...

Thanks oddson, that's a great idea forthe button feature, that way I can handle all note playing with the myNoteOn and myNoteOff functions. I have noticed the last voice/free voice thing in some...

I'm starting to see my code may be slightly more problematic than I thought. I have the waveform .begin statements in the loop of my code, so it looks like they are overwriting any value I try to...

Ok this isnt working because case cant be an array, but I feel like I'm on the right track...

Hello everyone. I hope the below ramble makes sense.

I am coding a synth using your audio board and a Teensy 3.6. So far everything has worked flawlessly but I have hit a wall. My synth has 8...

Thank you so much! This is going to cut my code down by at least 35%! Jacob.Schultz, I tip my hat to you, sir!
