HEXE FX - JawsFX

pz314

"I was tasked with designing a JAWS themed pedal as part of a birthday gift for a true fan of the movie.
This is what i came up with:

- pedal allows to endlesly loop the iconic music theme,

- play an instrument over it,
- add a few randomly chosen quotes from the movie,

- alter the music track with manual or envelope controlled lowpass filter.
Ontop of that the pedal works as a stereo plate reverb and can be used that way with all the background sounds switched off.

Uses Teensy4 as it's main audio engine.
... and being a birthday gift, has a few hidden easter eggs :)"

WVR : modern, open source, embedded audio for $25

Currently on Kickstarter here.

Quick details via WVR:

"WVR is an ESP32 with a nice DAC and 8GB of fast eMMC memory. 18 stereo voices of simultaneous playback (at CD quality), which I think is something really needed in this space, in an open source project, at this price point.

The project also includes
a USB MIDI HOST add-on board,
a neat JavaScript library called RC.JS designed to help Arduino folks build GUI's, using React Native and Expo
the ability to store multiple firmware binaries in the eMMC, with the ability to boot from any of them
some tools to make building multi-sampled instruments a snap
2 dev boards
a stompbox version
etc, etc."

via the Kickstarter campaign:

"WVR is an open-source embedded solution for audio, with surprising capabilities. It includes everything you need to get started with embedded audio, with no soldering, and no coding necessary. WVR arrives ready to operate.

WVR is also a highly versatile device, capable of powering a new generation of embedded audio design, thanks in part to its wifi and bluetooth radio, providing all the power of a versatile and extensible Graphical User Interface ( GUI ), without the need for a screen or other interface. Users can upload samples, manage firmware, set configurations, build sequences, or control any other data imaginable, both wirelessly, and intuitively, using their laptop, or mobile device, inside a web browser, or even on a native mobile app on Android or iOS.

Capabilities:

Playback up to 18 stereo wav files simultaneously, with ~1ms latency

Accepts virtually every audio file format, at any resolution, and any size, including wav, mp3, ogg, acc, flac, pcm, aiff, and many more

Upload audio, map samples to MIDI notes, configure pin functionality, apply FX, manage files, etc, all over WIFI, with the default firmware that WVR ships with, and without writing any code

Holds over 12 hours (8 GB) of stereo audio, at 16bit 44.1kHz resolution

Can buffer over 1.5 minutes (16 MB) of stereo audio in RAM alone, at 16bit 44.1kHz resolution
Optically isolated MIDI input, provides to-spec MIDI input implementation without any additional circuitry

14 GPIO pins, 8 of which can be analog inputs, and 4 of which can be capacitive touch inputs, plus the many peripherals available on the ESP32 .

WVR's Wifi can function either as a Station or Access Point (it can login to an existing wifi network, or can create its own network and accept connections directly from devices in range, without a router or local network of any kind)

write firmware in Arduino, and upload over wifi. Stores multiple firmwares onboard, selectable via the UI. Fully compatible with the extensive, and battle-tested ESP Arduino library, and the exceptionally powerful ESP-IDF framework.

use RC.js JavaScript framework to modify, or custom build, the User Interface that WVR serves to users, without prior knowledge of CSS, HTML, Babel, Node, etc. Even build and deploy native mobile apps for iOS or Android from the same code base. You can play with RC.js in this REPL, try modifying the existing code, to see how it's intuitive, and highly portable, component-based syntax works, and check out the README.md file to learn more.

onboard Ultra Low Power (ULP) co-processor means WVR consumes only ~10uA in sleep mode

8knobsPortable synthesizer and midi controller. | Indiegogo

"8knobs is a portable synthesizer and midi controller. Right out of the box 8knobs creates drones and atmospheres (ambient soundscapes). 8knobs encourages learning synthesis, electronics, computer literacy and experimentation. Built on the popular Arduino platform it readily embodies the character of the user. It is an open source and hacker friendly instrument, ready to morph according to a wide range of use cases."

https://www.indiegogo.com/projects/8knobs--2#/

"8knobs can be used as a MIDI controller through usb, as a plug-n-play device; this means no installations, no additional convertors, no headaches. The 8knobs DIY kit consists of a PCB, an Arduino Atmega 32u4, header pins, potentiometers, all the necessary electronic components, mounting hardware, a laser cut wood veneer body and a case made of hand stitched jute with raw unbleached cotton.

8knobs has 1 audio out, MIDI over USB or MIDI over 3.5mm to connect to other traditional synthesisers. It can be powered via USB, DC 9-12v wall adaptor or a 9v battery.

DIY

// Electronics // Sound synthesis // Computer Coding

While building 8knobs you’ll learn everything from the basics like soldering to the fundamentals of sound synthesis, electronics and computer codes by understanding, engineering and experimenting with signal flow. Learn the art of signal flow by building your own custom synthesiser and controller for more experiments!

Experience

// Creative learning and new approaches

Getting familiar with signal flow unlocks a wide range of new opportunities to innovate and produce technical as well as creative applications in various media - both analog and digital.

Just like the flow of signals in the brain are interconnected and influence each other. For example, like neurons communicating information in both chemical and electrical forms, can result in infinite combinations of thoughts, words, and actions, similarly, playing with signal flow in hardware (electronics), software (coding) and space (acoustics) can result in infinite creative expressions.

The art of signal flow offers endless possibilities, and whether you take it up as a hobby or use it to pursue a life-changing innovation is for you to choose. Either way, it’s a great feeling to get your hands dirty in the energetic flow of signals and DIY culture!"

Isla Instruments S2400: Audio Engine & Analog Outs Comparisons

Paul

"Showing the lovely differences you get in the S2400 using the difference sampling / playback engines. A rough conclusion is: if you want super old-school alias-heaven, sample AND playback using the 12bit engine. If you want to back off from this slightly, sample using the 24bit engine but playback using 12bit. In addition, you can remove aliasing using the analogue output filters or, just use these for effect.

Pad 6: Sampled: ‘Hi-Fi’ 24Bit 48Khz
Playback: ‘Hi-Fi’ 24Bit 48Khz

Pad 7: Sampled: ‘Hi-Fi’ 24Bit 48Khz
Playback: ‘Classic' 12-Bit 26Khz

Pad 8: Sampled: ‘Classic' 12-Bit 26Khz
Playback: ‘Classic' 12-Bit 26Khz

BTW, YouTube makes these comparisons less apparent; in real life, the differences are maybe 25% more obvious."
