I screwed up again, it should be:
Code:oscsB[i]->frequency(detune * noteFreqs[voiceToNote[i]]);
I screwed up again, it should be:
Code:oscsB[i]->frequency(detune * noteFreqs[voiceToNote[i]]);
Sweet! Just one thing... it seems to be uptuning... any idea's on how to reverse it? lol
Oh like, instead of the B oscillator being detuned to a higher frequency, you want it detuned to a lower frequency? You could do:
That will invert the detune so 1.0293 will become 0.9715... Not sure if that's what you meant though.Code:oscsB[i]->frequency((1.0f / detune) * noteFreqs[voiceToNote[i]]);
Yes, I think thats the traditional direction, no?
Actually I don't know, haha. I've only really heard the old "super saw" oscillators which had like 6 oscillators per voice, it makes such a wall of sound it was hard for me to tell. I'll have to listen again when I have time... maybe it detunes some up, some down?
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 noise oscillator, and I'm nearing completion! I am considering trying to teach myself to create new Audio tool modules, though my coding experience is limited. Ultimately I want to add LFO, noise, a wavetable oscillator (on that note, do you think replacing the current oscillators with wavetable oscillators may be a way to go? Like have wavetables for all the classic sine, triangle, etc, but also some cooler ones too? I'm still curious about your comment on not using built in oscillators)and have separate envelopes for each... all these mixers seem so unnecessary. Sigh... keep trudging and learning!

Keeping tight lipped Wcalvert? lol
The benefit of wavetables, at least as I understand it, is that you get to have samples recorded at different pitches. This helps make things more realistic because, for example, resonance effects change as the pitch changes. With the simple waveforms (sine, saw, square) there's not a lot of benefit there. You can pitch them up and down without any problem.
If you wanted to write your own audio modules... well, I think the sky is the limit. One idea I have been messing with over the past few days is taking a single-cycle sample of a waveform and looping it to make a new "oscillator". This could be used to make analog-ish squares and saws for example, which sound 'sweeter' than traditional digital squares and saws.
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 of it. I may have overcommented a bit, but I wanted to be thorough. I was wondering if you had a moment sometime if you could comment your code contributions a little deeper than you already have? I started to, I'm about 95% of the way there, but I got a little lost when you started using millis()... around that area (is that starting a timer, or grabbing an already running timers value?). Just kind of breakdown whats happening in your part of the code. If you get a chance and feel so inclined I think it would not only help me but future beginner coders as well. Thanks my friend! Here's what I've done so far.

Comments are good. Comments that state the obvious just add clutter. It's a fine line.
The loop in your NoteOff() function should terminate on first match:
It's a bit esoteric, since this might never happen...Code:// Function named NoteOff, receives 3 variables that can be use in the function. MIDI channel, MIDI note, and note velocity void NoteOff(byte channel, byte note, byte velocity) { for (int i = 0; i < NUM_VOICES; i++) { // Do this 32(NUM_VOICES value) times if (voiceToNote[i] == note) { envelopes[i]->noteOff(); voiceToNote[i] = -1; break; // Exit loop on first match } } }

Thats a good point. I thought I went a bit overboard, lol. Thanks for your addition, I will definitely slim down the comments.
Hey, well I can explain the voice stealing part pretty quickly. Millis() returns the time in milliseconds since power on. So to find the voice that has been on the longest (so we can steal it), we need to find the *lowest* value in the voiceOnTimes array. To find the lowest value, just iterate through the voiceOnTimes array and keep track of the smallest value ('oldest') and the array index of the voice we'll steal from ('voiceToUse'). At the end of NoteOn, I store millis() into the voiceOnTimes array for the voice that was acquired or stolen. That's where that array gets populated. Anyway, hope that helps.
Thanks Wcalvert, that helped a lot! You have been very generous with your time and I cant thank you enough. Happy Holidays!
