I've been trying to come up with something akin to Max Crook's Musitron (Think Del Shannon's "Runaway" and "Telstar")... which apparently was a modified Clavoline... I was tinkering with the bumblebee oscillator... and drawbar organ emulations... but there's something I'm missing... I think if I could make a keyboard playable version of "21st century theremin" from the UL, I would be pretty close, but I'm not sure how to go about that! In the meantime, I have been tinkering with drawbar organs and saw/square waves.
These are pretty simple instruments (I gather) but very distinctive. I would appreciate any advice on how to model these in Reaktor.
There are 3 basic units I'm thinking about:
"The univox" which one site says is much like a "clavoline" used a sawtooth oscillator and has these specs:
The Univox (1940)
Developed by the British 'Univox Company' the Univox was an instrument using a vacuum-tube sawtooth generator modulated by a diode waveform shaper circuit. The pitch range was extended to five octaves using a frequency division technique which also allowed the playing of multiple octaves of the same note from one key. The Univox keyboard had a unique a double contact system under the key allowed basic control over the note shape - striking the key harder caused a thyratron impulse generator make a shorter decay, creating a staccato effect, striking the key softly gave a long decay of up to two seconds. A vibrato oscillator was also provided to modulate the output and also to retrigger the thyratron tube to create 'mandolin' type repeated notes.
The Univox had a front panel of fifteen switches to further control the timbre of the instrument, three vibrato controls, a thryratron modulation control and an overall knee operated volume control. The Univox had a an external amplifier and ten inch speaker unit.
The Univox was noted for the realism in producing string and reed tones such as clarinet and saxaphone.

The "Univox" was built by JMI... before they became "Vox"...
For the "whole story" you can check it out here:
The clavoline used a square wave. The "Clavoline" has it's own "tribute" page (with musical/sound samples):
... since the clavoline used a square wave, I expect the musitron did too - you can find out more about the musitron here:
Any suggestions on how to model one of these little beasts? Anyone want to take a crack at it?
