【自作シンセ】アナログライクなFMシンセサイザーをラズパイPicoとArduinoで作ってみた。OP-F Synthesizer

video upload by Harumio 1529

Harumio also brought us the DIY Prophet 4.


"This video introduces an original synth that I made as a hobby.
The F in OP-F was named because it has 4 operators, 4poly per Raspberry Pi, was made in Fukuoka, and is my initial.
This was the hardest edit I've ever done. Watch till the end."

Zynthian V5 improvisation

video upload by Floyd Steinberg

"... using the internal sequencer.
Using the #ZynAddSubFX plugin mostly, but also #Linuxsampler for the drums and piano.
Some TAL Reverb III for those big rooms.
#Zynthian V5 will be available later this year. Zynthian is an open source synthesizer powered by Linux and various free and commercial plugins, all wrapped up in a sleek-looking box with a unified UI and a number of sequencers. If you don't want to buy the kit, you can also download the system image and build one yourself using a #raspberrypi 4.

Broken beats w/ Pikocore, Dirtywave M8, Roland J-6, TE TX-6

video upload by Arman Bohn

"More experiments with the pikocore. Random chord triggering sent from the M8 to the J-6. The Pikocore is synced to the J-6 which is clocked to the M8.

I’m syncing key changes to the random chords as well. I think I’ll continue down this path towards actual pseudo random song creation … so possibly more M8 + J-6 combos in the near future. The modulation options on the J-6 are nonexistent sound design is incredibly limited. I could use another mini synth instead, maybe the great conjunction, or the kasser arcade. but that would take more cord wrangling in the m-8."

This is the first post to feature the pikocore.

a small rp2040-based music mangler. $62 / $89.

pikocore is…

a lo-fi music mangler based on the raspberry pi pico (brother of the nyblcore).
capable of holding 8 minutes of 8-bit 33 khz monophonic samples.
powered by a single aaa battery for up to 3 hours or by powered by usb-c.
tempo-synced with a selectable bpm between 60 and 300, with samples mangled by beat-synced effects (stutter, retrig, gate, tunneling).
loaded with real-time effects like a resonant filter, timestretching, volume, and wavefolding.
sequenced with a 128-step sequencer with recording/playback
saved and loaded via eeprom for instant patch recall.
able to load custom firmware, new samples, all through usb-c.
sync-compatible with pocket operators.
open-source, wonderfully hackable.

Acids RAVE - Realtime Audio Variational autoEncoder

video upload by Realtime Neural Audio Synthesis - embedded RAVE #2 Acids Team - Ircam

From the makers of Neurorack.

"Official implementation of RAVE: A variational autoencoder for fast and high-quality neural audio synthesis (article link) by Antoine Caillon and Philippe Esling.

RAVE comes with two command line utilities, resample and duration. resample allows to pre-process (silence removal, loudness normalization) and augment (compression) an entire directory of audio files (.mp3, .aiff, .opus, .wav, .aac). duration prints out the total duration of a .wav folder.

Once trained, you can reconstruct an entire folder containing wav files"

"Demonstration of realtime embedded RAVE models on different platforms:

- Raspberry Pi 4 8GB
- Nvidia Jetson Nano 4GB

With RAVE + nn~ you can embed realtime neural audio synthesis inside single board computers !

RAVE project:

Antoine Caillon - ACIDS team - 2022

Special thanks to Victor Paredes for his help with the motion sensor"

MT32-PI: Doomsday device?

video upload by Floyd Steinberg

"This week, let's build and take a look at the #MT32 PI, another 'bare metal' synthesizer running on #RaspberryPi. This is an emulator for the late #80s Roland MT-32 sound module, which was used by a lot of games for their sound track. The MT-32 PI can also load soundfonts, so you can use it as a ROMpler in your setup. Table of contents:

New Maplin 5600s DIY Build Based on the Raspberry Pi

video uploads by Derek Walker

"Maplin 5600s Build - pictures & videos of the build in chronological order from the beginning of the project, August 2018, to the end, June 2019."


"I recently came accoss the contruction manual for my Maplin 3800 synthesiser and flicking through it I wondered would it be possible to build the 5600s systhesiser today, August 2018, nearly four decades on.

With the passage of so much time there will be a few challenges to overcome namely component obsolescence. Integrated circuits, spring line, patch board, keyboard but to name a few. Please read the 'Hindsight Engineering' section at the end of the page.

On the positive side the build process should be simpler. For me the circuit boards will be easier to produce, no more ferric chloride, bubble etch tanks, spraying copper clad board with photo resist varnish and so on. Just produce the gerber files (I used EasyEDA) and send them off to JLCPCB.

I'm still considering what to do about the patch bay, try to source one or simply bring the inputs/outputs to limited number small jack sockets so they can be 'jumpered' - no room for 900 sockets!

I am also considering usng the Raspberry Pi instead of a keyboard either as a sequencer or as a 'soft' keyboard. I will re-hash my sequencer program for use with the 7" touchscreen and find a space to fit it on the panel."
