[sdiy] quantizer questions..(Ray Wilson model just built)

[Ray Wilson]

Hi Dan

Something shes a not a hookda upa right.(Italian accent). Anyway... did you 
connect the switches for setting half, whole and fourths mode? Are you sure 
all of the components are on the board. I forgot a resistor in one of the D 
to As when I built mine and things were very weird until I saw the component 
legend with nothing in that position. I am certain that when built and 
connected properly the unit works well. It will follow about 6 volts of 
notes and will indeed output discrete voltages at multiples of .08333 volts. 
I will be putting up some samples so you can hear what it should sound like. 
I am connected to my sequencer and it outputs up to seven volts. Once you go 
above what the unit can output it will only output the max voltage (63 x 
.08333V). If you are only getting a couple of notes Something shes a not a 
hookda upa right.(Italian accent) again.

Are you seeing the waveforms I have shown on the page? Follow the circuit 
description and probe away until you find what's up. If you lived in Parker, 
CO I would be more than willing to lend a hand.

Good luck.

Ray
