Pleiades microphone pre preamplifier for ipad

It would be nice to connect a Pleiades T117 fet preamplifier to the ipad's mic-headphone  input.


The drain pin of the fet could be connected directly to the ipad or iphone or ipd touch as they can supply power through their internal load resistor!


A Pleiades input transformer can supply the fet gate input, so you would have an extremely low noise pure signal with proximity compensation, pop filtering and excellent sensitivity for your SM-58 or other dynamic or ribbon or even condenser mics.

Led Zeppelin modes

Opened almost by chance 2 youtube pages and they played almost in tune simultaneously..


One was Giorgos Skordalos at www.xilouris.gr playing the mantolin.


The other was Led Zeppelin - Inthe Light (vinyl).

The Pleiades Oscillator

The Pleiades Oscillator is a simple oscillator consisting of only a transistor output transformer with center tap for feedback to the base through a coupleing capacitir.

A photoresistor is conected between base and emmiter? so it acts as a theremin to easily produce different sorts of sounds. 

Growing Musical Notes

One can grow notes using the pleiades oscillator.


Than you can sample them with and ipad garageband sampler for example.


And then play.

Music Playing Electronic Game

It would be nice to have an Arcanoid type of electronic music making game.


Each brick is assigned a note say a whole tone scale. Temperament being a bit higher than x2 for octaves so that all notes especially very high and very low ones sound right.


As the ball hits the bricks music is being made.

Lyre Tuned to a Whole Tone Scale

Sounded like the sunshine.


This happened after watching the excellent lecture of Bernstein on Impressionism .


A scale close to D  E  F# G# A# C  D was used.


This gave the useful property of  the scale ending on the same note it starts on the 7 string Lyre.


Then everything was raised a semitone. The strings were further stretched and sounded much more harmonic.


The high D sounded shinny. The C not so, it was felt to be less stretched suggesting the use of a larger diameter string for proper scaling.


It would be nice to have many lyres tuned to a whole tone scale, or using one lyre and an echo of a few seconds to make a canon...
