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."

via http://www.bygonebytes.co.uk/Maplin_5600.html

"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."

Turning a Nanokontrol into a 16 step multitrack midi looper using a Raspberry PI Zero 2

video upload by Floyd Steinberg

"I turned my Nanokontrol into a 16 step multitrack midi looper using a Raspberry PI Zero 2, using WebMidi on Chromium. This is still work in progress, but I was so happy this works I wanted to share it online. ;-)
Hardware used:
PEAK - for the saw wave patch
Orba - Drums
Reface DX - Lead
PI - sequencer

How it works:
The Nanokontrol has 24 buttons, 16 of them are used as "locks" for the 16 steps in a measure. Pressing a key and turning the left knob "locks" a note in place (a midi keyboard can be used, too). Pressing a button and turning the second knob will adjust note length. The right knob will adjust the tempo of the track.

As this is a web app, all the MIDI stuff is "stored" as a DOM element. Each track is represented by an ordered list that's formatted to look like a table. Velocity, note length and pitch are then stored as data parameters.
There's a web worker running in the background which will provide the time, unaffected by what's going on on the web page. That thread will just count up to 16 in the interval deducted from the BPM and then start from the beginning. Each step, the thread sends a signal to the web page to read the next item in the list and send it to the hardware assigned to that track.

To Do:
- performance optimization for PI Zero (it runs pretty stable on anything else ;-)
- SWING :-)
- midi learning for any given controller
- loading and saving tracks as midi file
- on the fly creation of new patterns, copying the one currently played so you can tweak it
- on the fly pattern switching
- track muting

Once this is done, I'll release it for you to use. :-)"

Raspberry PI ZERO-2 synth improv

video upload by Floyd Steinberg

"So, can the #RaspberryPI Zero 2 run a DAW and some #synthesizer and effect plugins? Here's a short improvisation running on Reaper with 7 plugins loaded: 2 x Dexed, 1x TAL Noizemaker, Drum synth and 3 x TAL Reverb III I just let the camera run while improvising this. There's a bit of CPU stress near the end of this video, I guess Linux started swapping there, as the PI has only 512MB RAM."

How to Build a Raspberry PI Synthesizer by Floyd Steinberg

"A series of #shorts showing how to build a #raspberrypi #synthesiser.

To follow this series along, you'll need a Raspberry PI, an SD card, keyboard and mouse, and HDMI mini to normal cable, and audio and USB cables.

Start by going to raspberrypi.com. Click on 'software' and download the Raspberry Pi imager. Insert an SD card into your PC and install and launch the imager. Choose the first option, 'Raspberry PI OS 32 bit' in the list of operating systems, select your SD card and then click 'write'. Then wait until the process is finished. We'll continue in the next video."

How to install and use SURGE synthesiser on Raspberry PI / Lanthan's sound set challenge

Some days ago, @Lanthan O'Ide challenged us to create tracks using his new sound set for surge (see https://gumroad.com/lanthanoide).

ZYNADDSUBFX on Raspberry PI Linux - open source synthesiser (pt. 1 - installation and examples)

video by Floyd Steinberg

Support: https://www.paypal.me/alexselck

#ZYNADDSUBFX​ is a powerful, great-sounding, yet resource-saving software #synthesiser​, so it's an obvious choice for running a #raspberrypi​ synth. Table of contents and code snippets for copying and pasting below! This synth provides up to three seperate "engines" for each voice - there's a subtractive synth w/ waveshaping, a "noise filter" synth and a wavetable synth built into this. In this video, I download the source code, compile it, set up qjackctl, go through the basics, play some example patches, create a filter sweep pad and also create a delicious salad (for science!)

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. :-)
