Tube synth diy

I cant wait i have all the tubes for the ts22 i believe and i have 
one of the four band pass filters completed. Id love to put up those 
schematics but id have to get permission from eric im sure and he 
never publicly relases his schematics i dont belive. I suppose if 
you maybe email him a few times you might be able to get something 
from him. I just wish all information was free. Heres some 
imformation on it


TS-22 is unlike any other "filter" or "filter bank" offered on the 
market. It consists of four simple vacuum-tube bandpass filters. 
Their center frequencies are offset by 1 octave from the previous 
filter. Each filter is independently sweepable with panel knobs; or 
they
are all sweepable in unison, using either a panel knob or in 
external source of control voltage, such as an envelope generator or 
LFO. (A special optoisolator does the job.) 

Because these filters do not behave like solid-state filters 
or "virtual analog" devices, they sound very different from any 
other filter ever offered on the market. 

And the TS-22 includes a vacuum-tube pentode voltage-controlled 
amplifier (VCA) at its output, optionally usable in conventional VCA 
fashion in a modular synthesizer, to impose an envelope loudness 
contour on the filter output (using an external envelope generator). 
TS-22's CV inputs are 100% compatible with all existing envelope 
generators and
other modular-synth circuits. 

Thus, the TS-22 constitutes most of the signal processing path of a 
classical monophonic analog synth. Only with no transistors in the 
path. 



OH and the ts 21 is wild i really cant wait to try that one. its  a 
beutty!!!!.
