"In this video, I'm exploring the Erica Synths Echolocator — a hands-on stereo delay unit packed with character and performance-focused features. From tape-style echo and BBD-inspired grit to dual shimmer modes and real-time control, it’s built for deep, creative sound shaping. With MIDI and USB integration plus a rugged design, the Echolocator is perfect for both studio and live setups."

"This is the Schlappy Minute.

Today I show you how to use the Boundary Layer as three cascading envelopes, firing off one after the other, to create "strumming" type articulations."

"WirePluck is a new synthesizer created in the tradition of the Rob Papen brand, which is known for thinking outside the box with innovative musical instruments. These are all possible now due to the amazing power of today's computers!

At the heart of WirePluck are the three layers made up from four selectable source synthesis types, which allow you to create new synthesizer pluck sounds! And nope... the focus is not in recreating real acoustic instruments, but creating new inspirational sounds!

The user interface has been laid out in the Main screen in a way that allows for fast editing using the most important parameters, selecting different ARP presets, and selecting the ‘Advance’ screen on which all available parameters can be tweaked.

The 1st source synthesis type for each layer is ‘Wire’, a newly developed sound source that sounds a bit like hitting a wire.

The 2nd source synthesis type available is ‘String’, which uses a custom Karplus physical modelling synthesis.

The 3rd source synthesis type is ‘FM’, which is a 3-Operator FM (phase modulation) synthesizer. A unique addition is that each Oscillator also has a Pitch Envelope Decay control, which is uncommon in classic FM synthesis, but great to add extra pluck to the sound.

The 4th source synthesis type is ‘Wave’, which is a 1 Oscillator subtractive synthesizer lineup featuring an array of various Filter types.

All of these different sources can be combined in the 3 layers of course and each layer has its output routing.

The included FX inside WirePluck are ‘Distortion’ with various types, ‘Modulation FX’ which are Chorus, Flanger and so on, a Stereo Delay, and our top-notch Reverb!

WirePluck also features a fully featured ARP, an extensive Chord Memory section, Modulation Matrix and of course our cool ‘Ribbon Controller’.

Last but not least, we have added a bank manager, including many great presets by Rob himself and other sound designers!"

PlantsSystem-PRA32-U

video upload by plantssystem

"Build your own digital synth with PRA32-U × Raspberry Pi Pico!

ISGK Instruments' PRA32-U is a digital synthesizer that uses Raspberry Pi Pico.
The Pico and various circuits can be arranged smartly, making prototyping and modification a lot of fun, and allowing you to quickly put your ideas into shape.
This time I put together everything from MIDI input to sound generation and output, and it was extremely easy to use as the foundation for a homemade synth, and it was a very fun experience to build it."

https://risgk.github.io

Overview

4 Voice Polyphonic/Paraphonic Synthesizer for Raspberry Pi Pico 2/RP2350

Built-in Chorus and Delay FX

Controlled by MIDI -- PRA32-U2 is a MIDI sound module

Having the function of writing the parameters to the user programs and the flash

Modifiable with Arduino IDE and Arduino-Pico (by Earle F. Philhower, III)

An I2S DAC hardware (e.g. Pimoroni Pico Audio Pack) is required

PWM Audio can also be used instead of I2S (PWM Audio does not require an I2S DAC hardware)

Prebuilt UF2 files ("bin")

"Digital-Synth-PRA32-U2-Pimoroni-Pico-Audio-Pack.uf2" is for Raspberry Pi Pico and Pimoroni Pico Audio Pack

"Digital-Synth-PRA32-U2-PWM-Audio.uf2" is for Raspberry Pi Pico and PWM Audio
