Peak Town: Novation Peak and Elektron Digitakt

video upload by Hugh the Musical Engineer

"I had developed some drum rhythms on the Digitakt, and hadn't taken the Peak out for a while.
Found a nice FM sound with lots of filter control, and it matched the drum beats, so we have a techno track using sounds from Peak and Digitakt.
This one was 138bpm, so didn't get a chance for a sip of beer while recording this.
Trying to get back into the routine of creating and recording music, and when I go to the pub, I usually book the table for 4 hours, so that's how much time I have to try and get something done.
Created, arranged and recorded at Indigo Yard, Edinburgh on Friday 24th July 2026.
Wow, almost into August already. Festival time soon.
I felt I should have been wearing a cowboy hat last night. Lots of people dressed up for a show."

XpandrLink, a native Mac/Windows editor and DAW plugin for Xpander/Matrix-12 (beta)

This one came in on the xpantastic Oberheim Matrix-12 and Xpander list. Details from the creator follow:

"I'm Jake, a Matrix-12 & Xpander owner and synth repair tech. For the past few months I've been building something that has gotten a lot of use in my studio: XpandrLink, a from-scratch C++/JUCE editor for these synths built using XplorerEditor's protocol and design as reference, with standalone, AU, and VST3 builds for both macOS and Windows. I've been really enjoying having this tool for my own purposes and wanted to share it with the community if anyone else might also find it useful.

First, the part that matters most to me. Like many of you, I've used XplorerEditor for years. It's a big reason these synths are still practical to own and play, and this project only exists because of the groundwork it laid. I started down this road after reading a note more than a year ago in the XplorerEditor README: the developer had no time to add new features but welcomed forks and PRs, and recommended a long-term JUCE port for a more modern cross-platform foundation.

Erae Sound Tutorial #1 — Getting Started

video upload by embodme

"Erae Sound is our MPE software synthesizer designed specifically for Erae 2. Each preset combines a sound and a dedicated layout, sent directly to your Erae and ready to play.

This first tutorial gives you a complete overview of the instrument and covers the essential concepts you need to start using Erae Sound: the two sound generators, oscillator and filter routing, the FX section, the modulation matrix, editing shortcuts, and the connection between instruments, layouts and projects in Erae Lab.

You’ll also learn how to assign gestures and modulation sources to parameters, cross-modulate envelopes and LFOs, import generators or FX from other presets, edit a layout and save it with an instrument, and use Sync to recall instruments directly from your Erae.

A practical starting point for Erae Sound owners who want to understand the workflow and begin creating their own playable instruments."
