This is an old Princeton Applied Research Lock-In Amplifier. It was used for phase detection and noise cancellation, but here there is no input. Instead, it is being used as a tuned noise source and filter. A great tool for musique concrète or meditative drone sounds."

Crush And Bang Yamaha RX-17

http://bernhardtsynthesis.blogspot.com/

This is my modified Yamaha RX-17 I call the Crush and Bang. The Yamaha has been augmented with a 20 point patch bay (green and black banana jacks) as well as 5 patchable toggle switches, 2 patchable momentary pushbuttons, and two patchable potentiometers, 1K ohm and 100 ohm. This is its distrotion sounds, but it is capable of a huge variety of sounds."

Side Note: I'm finding that I'm not using the soft synth label on these. I don't use them for hardware VA synths, only PC software. When I see and play the iElectribe it feels like hardware.

Tonal Plexus V7 Tritones in Just Intonation

YouTube via AaronAndrewHunt — April 21, 2010 —

"Dominant 7th chords contain a diminished 5th between the 3rd and 7th. This is often called a tritone, although tritones are, strictly speaking, always augmented 4ths, not diminished 5ths. The misnomer is indicative of the way pitches are named enharmonically in 12ET. In Just Intonation, a diminished 5th will never be an augmented 4th. In 12ET, two dominant chords can share the same pitches between their 3rds and 7ths, swapping roles of those pitches between the chords. This can't happen in Just Intonation. This video shows how in JI either the 3rd or 7th can be used as a common tone, but not both. NOTE: the captions in this video introduced blips into the audio for some reason and I couldn't fix it; sorry. The keyboard in this video belongs to the Berklee school of music in Boston, MA, and is used there by David Fiuczynski and his students. Find out more about the Tonal Plexus at www.h-pi.com"
