Hi Doepfer interestees,
Thanks for those lists. Quite handy.
I have a WASP query.
I'm hoping someone can tell me how to calibrate the cutoff frequency so that
I can cut the sound out completely using the high pass filter.
I hope that's a clear request.
When I use the low pass setting, I can cut the sound out so that nothing
gets through, but when I use the high pass setting (or the band pass, for
that matter) the freq control knob ceases to have effect for the top quarter
turn, and there is quite a lot of the frequency range left unfiltered. ie.
All the top range is unfilterable.
I unscrewed the unit from the frame and twiddled the two trim pots on the
circuit, which seem to be designed for the purpose of calibrating the cutoff
in some way, but neither bring the high end cutoff range up.
Do other people's WASP filters work the same way
I find it quite unsatisfactory, in a way.
It seems to me it may simply be a fault of the circuit, though, rather than
poor calibration. If so, can anybody tell me if there is a component or two
that I can replace to extend the range
Thanks!

Subject: Re: voltage range of all the a100 CV cources
According to my cheapo voltmeter (which has an analog dial hehe):
A165: 0 to 9V
A160: 0 to 10V
A147 -4.5 to +4.5V
A155 Gate: 0 to 10V
A155 CV top: 0 to 4V
A155 CV bottom: 0 to 7V
A190 Gate: 0 to 9V
A191 LFO: -5 to +5V
A191 CV: 0 to 5V
A141: 0 to 6V
A162: 0 to 10V
A140: 0 to 7V
A119 Gate: 0 to 8V
A119 Env: 0 to 8.5V
A176: 0 to 5.5V
A145: -5 to +5V
I seem to recall Timothy did a more comprehensive list earlier when
the A150 bleed-thru issue was being discussed.
Joe (not a wizard)
A110 sine, pulse +/- 5.5V(there's no coupling capacitor, so stays
this no matter what pulse width set to), tri +/- 7V, saw +/-5V
A111 pulse +/- 4.5V (output is AC coupled, so this shifts to make DC
level zero, depending on pulse width), saw, tri +/- 3V, sine +/- 4.5V
A117 digital noise 0 � 12V, oscillator outputs (very) approx +/- 5V
A119 gate out 0 � 9V
A129/3 CV out (nothing in) 0 � 5.5V (daisy-chaining two sections can
add the same to this, to get up to 11V out)
A140 envelope 0 � 7V
A141 envelope 0 � 6V
A145 saw, sine, square +/- 4.5V, triangle +/- 5V
A146 bipolar pulse +/- 4.5V, unipolar pulse 0 � 8V, variable tri +/-
4V
A147 tri +/- 6V, sine +/- 5.5V, square +/- 5V, saw (unipolar) 0 � 7V
A156 trigger out 0 � 5V
A160/161 clock outputs 0 � 12V
A163 divided output +/- 2.5V; (DC output if capacitor shorted 0 � 5V)
A174: X/Y offset set to 0, full range of joystick gives approx -4V
to +4V; joystick central, turning X or Y offset gives approx the
same, -4V to 4V (hence you can get 0 � 8V out etc.)
A179 gate 0 � 9V, CV out swings through 12V, so -12V � 0 to 0 � 12V
possible depending on offset setting
A190 gate 0 � 9V
Some of these readings are quite rough and ready, and there may
obviously be some variation from module to module; also some VCO/LFO
outputs change with frequency.
Maybe other members can supply ranges for those modules I don't have,
e.g. A176 etc.
