Hi .
I made some photo's of the new 16bit quantizer check the attach zip file.
it is 4 channel multiplex meaning you can connect 4 analog sequencers and
convert which one that you like by trigger the "next channel" banana input.
so a 64 note sequence can be accomplish easily by using 4 analog sequencers
of1x16 each.
the channel order can be change in real time by using the "ch1" and
"up/down" banana
input's.
there are also 4 transpose cv inputs which are basically a cv mixer that sum
the amount of cv1 and transpose1 dc that comes from different analog
sequencers that run's at divide clock rate ,so for exemple for every 2 cycle
of the cv1 sequencer the transpose sequencer would advance to the next step
and transpose the sequence up or down.
there are also 3 bank of 8 scale while scale can be selected manually or by
gating the scale's banana jack's.
it is very nice when you change this scale's from a analog sequencer and the
LED's are corresponding to it .
but that is not all , infect the most important aspect of this quantizer is
its convert method.
three is NO internal clock at high frequency inside to run the conversion
sequence ,instead three is a banana jack for triggering the conversion
sequence from any analog sequencer logic gates or other control modules.
this conversion method gives the quantizer its great groove musical feel
when converting note after note by the analog clock which is the MOTM-300.
the total cv output error is max 250uV and the trimmers are cermet 100ppm/c
and the feedback resistors are 25ppm/c "HOLCO".
sorry for that long e-mail.
thanx

That is a very good DAC. As a matter of fact, that's the same DAC I used in
the Expressionist.
(Hmmmm, a lot of people have been talking about quantizers lately)

Hi.
I have just made a pcb for a 16bit quantizer.
it use the AD669BN very high accuracy DAC , it is a 45$ chip .
I powered it up yesterday and connect it to the MOTM300 and the result are
great.
it is a 4 channel quantizer with 3 bank of 8 scale each.
pictures are coming soon.
thanx
