[motm] Emulating Doepfer Modules with MOTM

2004-01-07 by elhardt@att.net

Doepfer has a bunch of unique modules and I was trying to figure out how to 
program their behavior on the MOTM.  Here are some tips on how to emulate 
those modules.

1) Doepfer A150 Dual VC-Switch.  Easily emulated with the MOTM-700 Dual VC 
Router since it's basically a more flexible version of the Doepfer module.

2) Doepfer A162 Daul Trigger Delay used to delay a trigger.  Easiest to use 
the MOTM-850 Pedal Interface with an extra EG.  Run the output of that EG 
into the Mix input then the gate output on the 850 into the EG you want to 
delay.  Use the gate threshold on the 850 and the Attack on the first EG to 
set the delay time.  Nice thing is this acts as a gate delay, not just a 
trigger delay as on the Doepfer.  The MOTM-700 can also be used as a gate 
delay also using an extra EG like above.  Note that these methods and also 
the Doepfer module only work well if the delay time is shorter than the 
interval between notes being played.

3) Doepfer A165 Sequential Switch used to bounce back and forth between 
multiple inputs to one output or multiple outputs from one input.  I like to 
use this to alternate between two sounds when a note is played (similar to 
Carlos' up-bow, down-bow demonstration).  Needs an MOTM-120 Sub-Octave Mux, 
two MOTM-830 mixers, two MOTM-800 EGs.  Run keyboard gate through IN2 on 
mixer #1, set knob to -5, set bias knob to 0.5 --> IN on MOTM-120 SUB2 
Output --> MOTM-800 #1 Gate.  So far this will sound a note every other key 
depress.  Now split off that same SUB2 output and run it through the IN2 on 
mixer #2, set knobs the same as above --> MOTM-800 #2 Gate.  The end effect 
is that you can trigger one sound every odd note and another sound every even 
note.
