I recognize the pedal but can't place it.

Circuit Bent "Animal Caller" with GetLofi.com 555 Oscillator Kit Creme DeMentia

YouTube via CremeDeMentia
"A GetLofi.com 555 Oscillator Kit, available from www.GetLoFi.com/shop, has been installed in this device. The 555 Outputs both a square wave and a ramp wave at the same rate. The square wave, when oscillating at a high rate, fools the toy into thinking that someone is blowing into the toy, which is what would normally control the looping. The ramp wave can be injected into the pitch circuit in place of +4.5v, controlling the warble effect. The pitch resistor has been replaced with a potentiometer and body contacts. Finally a distortion knob was added, which is a 1k pot between the two leads of the added 1/4" audio output."

"A selection of sounds created on the Elka Synthex. These are mainly pad sounds and all are single eight voice patches, some using the onboard chorus and with an external reverb effect added."

ARP AVATAR GUITAR SYNTHESIZER with MIDI

via this auction
"Originally released around 1977, it has been rumoured there was only 300 ever made. It was designed to be used with the hard to find and operate hex pickup system. NOT ANY MORE WITH THIS ONE!! This specific Avatar was modified by EMI in Minneapolis with a MIDI retrofit that allows you to use and access the sounds via any MIDI device/controller. And yes, it works!

The Avatar has many of the same sounds and functions as it's legendary family member, the Odyssey. This Avatar puts those famous tones at your fingertips, for a fraction of the price."

Digital Auto-Tuning and Digital Memory for the Yamaha CS80

via gavincurtis on the Yamaha list:
"Been experimenting with a prototype digital tuning add-on for the CS-80. A small micro-controller board calibrates all critical oscillators to a reference crystal via serial data controlled trim-pots on demand. Never have to open the unit up again for tuning.

Also working with a memory preset system which has been a challenging design concept so far. Like the auto-tuner, is a relatively compact circuit board that fits into the case of the CS-80. A low profile remote user panel fits to the underside of the micro-slider memory cover via a 4 conductor ribbon cable. The add-on is only visible when the cover door is open.

You program the keyboard as you normally would by adjusting the micro-sliders to obtain the desired sound. Then select any one of 999 available memory locations and instantly store that setting into digital memory. You can also copy any store sound settings in your library to a row of 5 "radio preset" buttons for instant performance presets. A 2nd identical digital storage interface is directly below and is for the 2nd set of micro sliders... so nearly 2000 presets could be stored.

The memory preset system has it's own internal bank of digitally controlled trimmers that exactly mimic the control panel sliders. Imagine if each micro-slider had a twin internal motor driven slider controlled by a computer.

The memory preset system records the slider positions you set with your fingers and stores their positions into any one of the 999 spaces in the FLASH memory. Simply call up any of the (up to 999) memory locations, the internal pots instantly move to the desired positions.

Technical to install, but would be very clean. It could also be removed at a future date and keyboard returned 100% to its original state if desired."
