video upload by RaspiAudio



"🎛️ Introducing Modu-Grain: The Granular Synth for MODULOX BRAIN! 🎛️

🔗 More info & get yours here: https://raspiaudio.com/produit/brain

We're thrilled to introduce Modu-Grain, a powerful granular synthesizer for the MODULOX BRAIN, designed for music creators and sound designers! 🎶

🧠 What is MODULOX BRAIN?
The RASPIAUDIO team has spent two years developing an open-source audio synthesizer platform. Our vision? A versatile hardware unit capable of running multiple applications. This week, we're releasing the Granular Synthesizer, with more to come, including Sampler, VA, and FM. Our open-source code on GitHub allows the community to create and share new applications!

⚡ Why Modu-Grain?

Comes with pre-recorded samples
Four-voice polyphony for rich sound layering
Adjustable sound parameters (grain size, density, envelope, random playback, sample duration)
Real-time waveform visualization and boundary adjustments
Live sample recording via built-in mic or external input
Customizable real-time effects: Filter, Delay, and an assignable LFO
MIDI support for integration into any setup

💾 How does it work?

Precompiled firmware available in our [app store] (apps.raspiaudio.com)
Community-driven: Modify, enhance, and expand features!
🔧 MODULOX BRAIN Specifications:

24-bit DAC & ADC resolution
320x240 color screen
Headphone jack + onboard mic & speaker
MIDI in/out (3.5mm jack) + USB-C MIDI
Expandable via magnetic connectors for MODULOX devices (Knob, Touch, Slide)
Nano pad anti-slip bottom for stability

🎛️ Accessories Included:

3.5mm jack to MIDI DIN RX-TX + sync cable

🚀 Join the Open-Source software Revolution!
MODULOX BRAIN is more than a synthesizer—it’s a platform for endless sonic exploration. Download the firmware, modify it, and create your own instruments!

Building a desktop piano synth with Raspberry PI and SFIZZ

video upload by Floyd Steinberg

"In this short series, I'm building a small #raspberrypi #synthesizer box for piano & string sounds, as suggested by a viewer who could use such a box in worship music . Part One: #SFIZZ and the Salamander Piano. Table of contents:

00:00 introduction
00:45 hardware needed
01:24 hardware assembly, installation
02:04 software setup
04:29 launching sfizz & stuff
05:23 important things to consider
05:44 trying this on a Raspberry PI Zero 2
06:32 ... and on the Raspberry PI 3b
07:00 conclusion, outlook, short demo
07:57 bye-bye

MINIDEXED - honey, I shrunk my DX7 collection

video upload by Floyd Steinberg

"MINIDEXED is a superb implementation of 8 instances of DEXED, the free DX7 emulator, on a 'bare metal' Raspberry PI. Think of a TX816 in mini format. In this video, I walk through the installation, setup and navigating the menu. Table of contents:

00:00 introduction
01:00 assembling the PI setup (LCD and rotary encoder)
01:32 other hardware needed
02:45 installing and configuring the software
03:30 navigating the menu, setting up a performance
06:34 important considerations
06:54 demo (synthwave... )
09:36 bye-bye

You can also buy one of the sets by Freenove: https://amzn.to/3rtuvBR - these will get you a lot of components useful for synth projects."

Using Reaper DAW and software synthesisers on the Raspberry PI 400

Floyd Steinberg

"Using Reaper DAW and software synthesisers on the Raspberry PI 400 - table of contents below! The Raspberry PI 400 has enough CPU power to run multiple virtual synths and effects simultaneously. Let's waste these resources trying to run the ARM version of Reaper with software synths and effects. Reaper on ARM Linux does not have VST or LV2 compability, but we can use Linux' audio subsystem to route our audio and MIDI signals from one standalone app to the next, using even WebMIDI apps within our DAW.
Note: everything shown here will also work on all the other Raspberry PIs. Reaper is a very lean software, so it's a perfect match for the PI. If only it would support LV2 plugins. :-)

Table of contents
00:21 Introduction
01:00 Hardware overview (you should also buy the PSU)
02:43 Downloading and installing Reaper
03:19 solving the "there was an error opening the audio hardware" problem
03:47 ... and the "no midi devices found" problem (a2jmidi)
04:50 ... and the "no plugins available" problem (synthv1 and qjackctl)
05:14 how to set up the midi and audio routing in qjackctl and Reaper
05:54 armed with that knowledge, recording vocals & a synth track
06:54 adding an external webaudio reverb effect to a track recorded previously ("pavucontrol" and pulseaudio-module-jack)
08:42 recording a track with that reverb effect
09:51 conclusion / bye bye"
