Roel, a while ago I posted details of the 16-note patch for someone 
else. Do a search of the message archive, or take a look in the 
database.

Hi Joe,

Thanks for your comment. I don't think that there's something wrong with the A 150! I think that I made some error along the way. I try again, let you know if I suceed.

hi list,
by the way,the triggers from my a155 pass right thru
my a150!!!!!!but the gates work o.k.!!!weird???

that is an issue that would be more clear if doepfer would write the 
values for  the input and output voltage  range in their manuals. 
seems to me that the cv input needs a voltage longer than a trigger 
i.e. spike in order to react, therefore only gates do the job. 
because if you used a triangle wave, it would send it into a frenzy. 
so try it and see what happens. seems the circuit reacts that way in 
order to avoid a fluctuating voltage or a rapidily increasing or 
decreasing voltage.

RM

no,RM,
i mean that,if i connect one of the triggers output of
my a155 to the i/o jacks of the a150 ,that they pass
right thru the switch...not in the CV jack.

bakis, 
i dont have a 150 to see what you mean..but if you have a 162 
does that help?  (maybe this has already been suggested) i use 
the 162 on the 155 trigs to turn them into gate signals when 
necessary.  set delay time to '0' and vary the length to set gate 
time. 
duff

Thats how I use the A162 also. Too bad it doesn't CV control of delay 
time to create "swing" notes (oops! no suggestions for improvements 
please!) 

This seems to be the primary use for the A162, since it's a 
free-running module and isn't very good for delayed modulation as 
suggested in the user manual. The A170 Slew Limiter patched to an A150 
switch is a better approach for delayed modulation.

Joe

nice tip duff,
very useful to turn triggers into gates...
thank you!!!!

you can acieve some thing useful with the a142...by 
voltagecontrolling the decay time you can have voltegcontrolled gate 
length for the gate output.

explain more,please...
synthfreak

Patch a gate signal to the A150 Switch's I/O2 jack, and also to the 
A170 Slew Limiter's input jack. The A170's output is patched to the 
A150's CV jack. The A150 O/I output is patched, for example, to an 
ADSR for a delayed envelope.

By adjusting the "rise" slew rate, you can control the length of the 
delay between the time that the gate starts, and when the A150 switch 
closes, feeding the shortened gate to your modulation patch. 

The "fall" slew rate is kept to zero so that the delayed gate ends 
simultaneously with the original gate. This is the big advantage that 
this patch has over the A162, which doesn't respond to the end of a 
gate. The A162 starts at the trigger leading edge, delays, then 
outputs a gate for a predetermined time, regardless of whether the 
note being played is sustained or staccato ("free running").

i like your suggestion about the A142!

Joe

hi dugg,
i don't think that this will help because the problem
is that the triggers from the a155 are from 0 to
+12volts and that's the problem(gates are from 0 to +5
volts)...but i think attenuating them with the a129/3
will be the solution...

bakis, 
hmm, your comment prompted me to measure these voltages.  to my 
surprise, here are the results: (i'm sure there's some variance from one 
module to the next as well)

A155 triggers send 7-8v and the GATE sends 10v
A162 TRIG output is 10v
A177 foot controller GATE output is 12v (!!)
A178 theremin gate output is  8v, 
A190 gate output is 10 v.
and just to make sure i'm not hallucinating, a 9v battery reads output of 9v.

so i don't know what's up w these reported specs..

the A129/3 must have slipped by me somehow, never realized the potential of 
this module outside a vocoder system, and i now see it as a necessity.  yikes!
duff

hi duff,
thanks for your measures...i don't have a voltometer
so i beleive the values that you measured arer
correct.so,triggers(7-8volts)are a mystery...why won't
they work with the a150???the gate i have tested comes
from the kenton pro-2000 and it's 0 to +5volts,so,it's
expected to work o.k.,with the a150......more tests
need to be done...

Instead of the gate signal, another possibility would be to patch an 
LFO directly to the A150's I/O2 jack, with the output jack patched to 
the VCOs, adding vibrato to sustained notes. Alternately, the A150 
Switch could be replaced by an A130 VCA in order to "ramp up" the 
vibrato.
