"We recently acquired these two consecutively cute curiosities courtesy of a very inspiring and equally interesting gentleman and great friend of the late Don Buchla. When I brought them back to the shop, naturally I plugged the 101 in and attempted to get proper scaling and triggering sound out of it for 45 minutes, watching videos reading pointers etc. Finally I tried turning the 5 pin keyboard plug around, and then I lost 4 hours in seemingly 10 minutes. I was floored. I didn’t hook up the 200. The next day I delivered these to my friend and tech in Santa Ana. Within a week he had checked them out , addressed any issues and found them to be fully functional and in great working condition. So I picked them up and was really excited to try the 200. Got back to Fullerton and plugged it in with a mf-104 tailing into an early cooper cs-106+ and went to heaven. The spring sounded like the grampian, the preamp is also in that vein, dual ring modulators are very special. In particular as a studio piece the stereo functionality takes this to another level, signal processing to use while mixing or effecting tracks Is very much more than 1/2 the value with the 200. Awesome machines."

Techno Pattern with Bullfrog Drums 🐸

video upload by Yan Cook

"I absolutely love the form factor and tactile, analog feel of the Bullfrog Drums. I think this 7-track sampler could be an amazing gift for a teenager who's interested in music production, and the built-in microphone and speaker make it even more fun and immediate to use. If I had gotten this when I was 15, I would have gone crazy and used the hell out of it 🙃

In this video, I create a Techno pattern from scratch using all seven tracks and only the factory samples of the machine."

Polyend Drums - First Sounds of FM

video upload by Polyend

"This track explores the new FM Synth engine for the first time. Piotr paired a gritty FM bass-line with minimal industrial rhythms

The new FM Synth engine brings a different character to Polyend Drums, from dirty basses and abrasive leads to evolving textures. Everything in this performance was created directly on Polyend Drums."

Send and returns

video upload by WMDevices

"Sends and returns are one of the most powerful and most misunderstood concepts in mixing, and they work exactly the same way in Eurorack as they do on a big analog console. This video walks through how AUX sends, pre/post-fader routing, bus outputs, and the master insert all work on the Performance Mixer MKII, using Cosmic Debris as the effect. You'll learn why effects return directly to the master (and why that's the point), how to keep delay tails when you pull a fader, and when to reach for pre-fader AUX 2 vs. post-fader AUX 1. Concepts apply to any mixer with sends."

Full MPE Firmware Test: 700 VOICE MPE Architecture with iPad Bluetooth MIDI

video upload by Gm Xe

"This video showcases the full MPE system firmware test for the 700 VOICE synthesizer.
All audio in this recording is generated directly from the 700FM VOICE module. We put the device’s MPE control system and native 700 VOICE MPE architecture through a comprehensive functional test.
We use an iPad as our controller, sending MIDI data wirelessly via Bluetooth MIDI for this evaluation.
Tested features cover all 4 dimensions of MPE expression, note quantization, key tracking playability, as well as MIDI CC mapping functionality.
The 700 VOICE MPE implementation supports slider modulation mapping for all available parameters, enabling independent modulation control for every polyphonic voice assigned to each individual touch gesture.
In this demo, we use slider controls to modulate Filter Cutoff (Index 3, Index 2, Index 1) and Oscillator 4 parameters.
