There are only so many ways to generate music with a computer, and by far the most popular method is MIDI. This chip was originally designed for cheap toy keyboards, but if you have a chip, you can do anything with it. The Fluxamasynth Modules are inspired by the original Fluxamasynthan Arduino shield that is basically a breakout board for the SAM chip. The Fluxamasynth Modules extend the capability by adding more support, including stereo output, reverb, chorus, flange, and delay effects, and digs down deep into the configurable parameters for tuning.
The hardware is basically an audio appliance for the Arduino, Raspberry Pi, and the ESP32, and allows for generative music through code. You can see an example of this project in the video below.
They register on pad and auto-center better with solder surface tension than most parts. Just be generous with flux, pre-tin the pads a little, and use hot-air — cake…. Not to be evil Dr. Pentanto, but despite creative labs old marketing, wavetables are something else. See Waldorf wave or blofeld or ensoniq fizmo. But yeah.
The functionality you are talking about table or rather a collection actually of waveforms acting as a general MIDI synth is probably closer to rompler-functionality. The implied functionality of a wavetable is that an oscillator looks up the amplitude for a given phase, instead of calculating it, sometimes to save CPU, sometimes to achieve morphing capabilities, sometimes both.

On the contrary a lofi 8bit wavetable engine is implemented and the sounds it produces have an 80s vibe. Currently the sound engine does not utilize an audio buffer and all synthesis takes place inside an Interrupt Service Routine that writes audio to the 2 8bit DACs of the esp However the code from those two libraries is floating point and that is a no-no for code running on an ISR on the esp So instead of using floats, the library Fixie provides a fixed point implementation.
This is a work in progress so this file will be updated with additional info as the project progresses. For testing I assembled 2 boards using perfboards and thin wire. I used 2 different esp32 modules.
Currently I do not use the psram. I added a midi in and midi out circuit, and a headphone jack for audio output. I also plan to add support for text IIC 2x16 character displays.

ESP32 Synthesizer libray on the way…
We found and based on your interests. Choose more interests. ESP32 is really awesome little computer. Two CPU cores, high speed, a bunch of peripherals, wireless networking, low price. It even has a built in DAC. It's only 8-bit, but hey! It's there! So, an idea came to me What would it be like to build synth based on that CPU. I was really surprised not to find existing synth designs for it so I decided to make my own. Even better - why not build it inside a bass guitar and have cool synth sounds to mix them with direct bass sound.
And the best part is that it doesn't even need keyboard - pitch can be extracted from the direct bass signal! Integrated DAC is only 8-bit but it will be enough for first prototype. Like always, whenever you want to do "just this" it turns out all bunch of things get in the way. It turns out things can't really happen as I imagined. Here I'm thinking about the blend between the bass guitar sound and synth sound.I have been playing around with the ESP32 micro controller.
Chances are that this will be my new favorite. Having plenty of horsepower and being cheap as dirt is just the beginning. What really has gotten me going is the ability to do down-to-the-metal signal processing.
I envision this controller a great future in areas such as audio processing applications, software defined radio and signal synthesis. Just for kicks I started generating some arbitrary waveforms using the internal DAC and the awesome built in I2S DMA that automatically copies buffers of samples directly from memory to the e.
I quickly realized that writing a music synthesizer library would be pretty straight forward. This is my first attempt at this. This serial data could now be sent to one of the extra serial ports on the ESP The synthesizer program internally calculates all sound using 32bit float point data but since the built in DAC of the ESP32 only operates in 8 bit the resulting sound is of a pretty crappy.
I knew that if i could get a better DAC I could get a much nicer result. It turn out that the same data can be sent as I2S data to an external DAC so I went and got one of those as a small breakout board from Ebay. Anyway, this is just a post to present some preliminary results the actual release of a full ESP32 synthesizer library will follow shortly as I get everything ready….

Parameter mode is the main mode of the synthesizer:. Each major mode has sub modes. Select sub mode. Original CC assignment is still working. It won't be affected with MIDI dumping. The diagram is for explanation, it may not cover all features in the OSCs. Unlike most hardware synths, all parameters can be controlled via MIDI including dials. Blue: Sources Green: Output. The oscillator is a hybrid of classic analog synth and FM.
See FM Conf Sub mode for detail. See Granular sub mode for detail. The synth has an unique behavior with pulse width. You can modulate the wave shape by pulse width, not only limited to Square wave. The Delay can be set very short. Very short delay can be used to create an interesting simulation of flute or violin.
The synth has four Envelope generators. This is a unique feature of the synth. When it is not zero, then note number above the parameter becomes LFO rate controller. If you set 60, then C4 or higher note becomes LFO controller. Higher notes will generate higher LFO rate.
If you press multiple notes, it doubles and triples the rate, great for live performance. The synth has one filter. Linear gives organic resonance, Non-linear gives more character.Our newest features are released on Skype Insider first. Skype Insider is for anyone who wants to experience the future of Skype now.

On Saturday at a sold out Theater at Madison Square Garden, dual Olympic champions Vasyl Lomachenko and Guillermo Rigondeaux go mano a mano for the formers WBO Super Feather strap.
It reminds me of Sugar Ray Leonard vs Marvin Hagler, two skilsters at the very highest level. Look how easily both have dealt with top opposition. Riga has much faster hands and being the bookies underdog might inspire him even more. Too big, too fast, too young. If he connects clean, I can even see him stopping Rigondeaux. I think Rigondeaux wins a tight, thinking fight, rather than a physical fight.
He showed holes that Rigondeaux can exploit. Rigondeaux never fights, always boxes. I see him draining the Cuban and then overwhelming him. Joseph Agbeko (ex two time IBF bantam champion) told me Rigondeaux punches brutally hard. Lomachenko already has one loss on his record and will lose again. A good big fighter beats a good little fighter and Lomachenko could even stop him.
I see him winning by stoppage somewhere around the eighth or ninth. He attacks from angles rather than straight lines. Rigondeaux is very patient on the back foot and has exceptional timing but I think Lomachenko will be too busy and too big physically. What a match up. No one has more ability than this pair.
Both have got talent pouring out of their ears. Both have got great attributes and can win any fight on their best day. Rigondeaux is the more experienced and very sharp. He might be able to catch Lomachenko and deliver the knockout blow.
So, IOW, after the fight ends, there will either be 11 experts who are no longer experts, or 3 experts who are no longer experts. My head is spinning. And someone posted yesterday that around the time of the weigh-in, Vegas odds were 2. He's too good for him. Tags: Vasyl Lomachenko Guillermo Rigondeaux Lomachenko vs.
