Ouwe rot
tja deze staat al lange tijd te wachten op een goede techneut. ik heb hem ooit voor 80,- bij een bulk gekocht maar heeft nooit gewerkt zoals hij zou moeten werken.
het synthgedeelte zelf werkt maar de midi niet, daarbij is hij vrij slordig gesoldeerd.
ik heb er met online hulp van PAIA een cv/gate-in op gebouwd, die heeft gewerkt maar geef er geen garantie op.
dacht zelf dat ie voor zo'n 50,- euro naar de volgende eigenaar mag.
er is genoeg info te vinden op het web

Adding external pitch or velocity cv inputs to the FatMan.
Closed Circuit (c.c.) Phone jacks, 1/8" or 1/4", can be used to both
interrupt the normal cv circuit and substitute an external cv. The cc jacks work to
switch the cv from the internal source to an external source whenever a plug is
inserted. In addition to the normal Tip and Sleeve, these also have a Shunt
(or Switch) contact and terminal. This contact normally rests against the Tip
contact but when a plug is inserted, it pushes the Tip contact away from the
Shunt contact opening the Tip-Shunt circuit.
Using this type of connector to implement external cv input function on the
FatMan eliminates the need for an Internal/External switch in addition to the
added input connector.
The FatMan CV source to destination (pitch cv to VCO, or, velocity cv to
VCFand/orVCA) circuit is opened by disconnecting board to panel wiring. The
circuit is completed again by reconnecting it to the Shunt terminal of a cc jack
and adding a wire from the Tip terminal of this cc jack to the original
destination.
PITCH
The FatMan Pitch CV originates at circuit board wiring point (AI) and goes to
panel control R71-3, the VCF pitch_cv_amount ((and from there on to R32, the
Glide control over another wire) and then back down to the board and then back
up to the Pitch control before going to the VCOs). This is where the new
external_pitch_cv_input c.c. jack is to be wired. Disconnect the wire from AI at
the R71-3 terminal and reconnect it to the shunt terminal and add a new
length of wire from the tip terminal to R71-3 where AI had connected. The sleeve
terminal of this c.c. jack connects over to a nearby circuit ground/common
point (ie R71-1) using a new length of wire.
VELOCITY
The FatMan Velocity CV originates at circuit board wiring point (AJ) and goes
to panel control R69-3, the VCF velocity_cv_amount (and from there on to
R104, the VCA velocity_cv_amount control over another wire). This is where the
new external_velocity_cv_input c.c. jack is to be wired. Disconnect the wire
from AJ at the R69-3 terminal and reconnect it to the shunt terminal and add a
new length of wire from the tip terminal to R69-3 where AJ had connected. The
sleeve terminal of this c.c. jack connects over to a nearby circuit
ground/common point (ie R69-1) using a new length of wire.
The panel controls for the Velocity in the VCF and VCA sections and the Glide
and Pitch in the VCO and VCF sections affect the external cv input to these
added connectors. The normal FatMan cvs range from 0-7v and the external cvs
should be kept within this range. The original cvs have no effect when the
external cv inputs are connected. To get an external gate input requires a
modification involving the addition of a new IC and some extra associated
components. Contact PAiA technical services for these details.
