That just reminds the compiler that it's a floating point number rather than a double. It's just one of those little hand optimizations that I always do whether it's really needed or not.

That sounds awesome but my only real C++ experience is super limited to this teensy stuff. :/Originally Posted by tele_player
For a larger synth, yeah it is needed. I have an instrument class, and 8 derived classes to encapsulate each instrument type. The derived classes hold the oscillators, envelopes, filters, NoteOn, NoteOff, assignable modulation stuff, parameter saving and loading... and on and on. But for a beginner's demo, object oriented might be a little too much.
Strictly speaking, a double is a floating point number. But in C and C++, a float is a lower precision FP number than a double.
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...
... it seems the waveform knobs go through more than two waveform types, even though WAVEFORM_SINE and WAVEFORM_TRIANGLE are the only ones specifically mentioned... why is that? Does the compiler fill in the blanks or am I missing something?
Oh I misunderstood what you were asking when you posted that originally.
What's happening is the map function is converting the pot reading to four distinct values, 0 - 3. Sine and triangle are the starting and ending values that it uses.
What waveforms are you wanting it to use instead?
Wcalvert: in your stuff, have you come up with something better than cascaded 4channel mixers to handle many voices?
I just edited the mixer class to have 8 inputs, it's a simple change. Most of my instruments have only 6 voices, and one has only 3 voices due to how CPU hungry they are.
Oh, and it's really easy to change the number of inputs in the GUI editor code too. I have added all my additional stuff to the GUI editor so I can still use it, it was very easy.
Interesting, I never investigated extending the GUI.
Just clone or download the Audio library, open a command prompt, change into the directory where you downloaded it, type "python -m SimpleHTTPServer" and then go to localhost:8000 in your browser, and boom, the GUI editor will be there. Edit index.html starting around line 345, and all the object definitions are in a big blob of JSON data.
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?
Now you've really got me wondering... what voices are using that are so cpu hungry?
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 be new to this but creating custom audiotool objects is too intriguing not to try!
Added 16 voices, check to see if filter pot has been moved before updating. That's all for tonight. Thanks again everyone, especially wcalvert!

Serial.printf("Knob 1: %d\n", wave1); for (int i = 0; i < NUM_VOICES; i++) { oscsA[i]->begin(wave1); } } // Same thing for B oscs. if (wave2Temp != wave2) { wave2 = wave2Temp; Serial.printf("Knob 2: %d\n", wave2); for (int i = 0; i < NUM_VOICES; i++) { oscsB[i]->begin(wave2); } } //Lowpass Filter int filterKnob = 10000 * analogRead(A3) / 1023; if (filterTemp != filterKnob) { filterTemp = filterKnob; filter1.frequency(filterKnob); //Resonace will be controlled by its own knob filter1.resonance(3.8); } } for (int i = 0; i < 8; i++) { mybutton[i]->update(); if (mybutton[i]->fallingEdge()) { NoteOn(1, buttonFreqs[i], globalVelocity); } if (mybutton[i]->risingEdge()) { NoteOff(1, buttonFreqs[i], globalVelocity); } } IdleCheck(); midi1.read(); }
That's how it's setup to work now. Just uncomment the lines "Serial.printf("Knob 1: %d\n", wave1);" and "Serial.printf("Knob 2: %d\n", wave2);" You should see each changing between 0, 1, 2, and 3. 0 is sine, 1 is saw, 2 is square, 3 is triangle.
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.
You can do that, sure. If you look here near the top of the file: https://github.com/PaulStoffregen/Au...nth_waveform.h
The waveforms have been #define'd, that's how the compiler knows what number corresponds to each waveform type.
Ahhh sweet I get it. Thank you sir!
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 though, if I run up some keys one at a time and there is a little release time active, it seems to skip a note. Like do-re-mi-fa-blank-la-ti-do. There just seems to be a lot of note skipping and some other weird behavior... notes jumping around etc. Any idea what that may be? Do I need to turn off audio interrupts somewhere else in the code? Wcalvert I know you said the synth was showing some strange behavior and I'm beginning to think it wasn't your midi program.
Also I need a little help implementing detune... I'm having some trouble wrapping my head around where to add the " - detuneKnob" code... in OnNoteOn? In the loop with a for statement and re-begin all the oscillators whenever the detuneKnob variable changes? Sigh... any help on these issues would be hugely appreciated! I posted the new code below. I hope all are well!

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.
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 above design tool code. I fixed the numbering issue and it's playing beautifully! Sweet!
I still could use some help on the detuning question, if you get a moment.Here's the new WORKING code!

Glad you got it working.
I don't have time to integrate this into the code right now, but it would go something like this. First define a global variable called detune:
Let's say we want a max of one semitone (100 cents) of detuning. In the pot reading code, let's convert the pot reading so that full ADC reading is 1 semitone of detune:Code:float detune=1.0f;
Then, in NoteOn, just change oscsB to use the detuning:Code:int cents = 100 * analogRead(Ax) / 1023; detune = pow(2, (cents/1200));
The detuning gets calculated as a ratio, for example 50 cents is 1.0293. So if oscA is playing 440Hz, oscB will be playing 440*1.0293 = 452.8Hz. If we had more than 2 oscs per voice, I believe most synths would divide the detuning up so that the total spacing between all the oscillators would be 1 semitone at most.Code:oscsB[voiceToUse]->frequency(detune * noteFreqs[note]);
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.

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 you are holding down a note, and not just triggered only at OnNoteOn(). Thanks Wcalvert!

Oh, nice catch, pow() needs both arguments to be double or float, that's why it wasn't working.
Making it continuously sweepable... Hmm, that's a cool idea, I hadn't thought of that. You could probably do something like:
Here I show the detune being read every time through loop()... it should sound pretty good like that I would imagine.Code:void loop() { // other synth code here... float cents = 100 * analogRead(A17) / 1023; float detune = pow(2, (cents / 1200)); for(int i=0; i<NUM_VOICES; i++) { if(voiceToNote[i] != 255) { oscsB[i]->frequency(detune * voiceToNote[i]); } } // other synth code here... }
I was HELPFUL! lol
So I tried this:
And the note is just detuned really low and the second oscillator isnt in tune with the first at all... here's the whole code, I'll keep poking around... the notes seem right and detune is going from 1.0 to 1.06 like before...Code:float cents = 100 * analogRead(A17) / 1023; float detune = pow(2, (cents / 1200)); for (int i = 0; i < NUM_VOICES; i++) { if (voiceToNote[i] != 255) { oscsB[i]->frequency(detune * voiceToNote[i]); } }
