Patch Examples:
“DJ” Cueing System
Patch two audio signals to ChA and ChB inputs. Choose patch to send to PA with Crossfader, output
Master Line OUT to PA. Monitor Cue Output with headphones to audition the other patch. When ready,
use Crossfader to switch to the other patch in the PA.
Two-input mixer
Patch two audio sources to ChA and ChB Inputs. Set mix with Crossfader. Take output from Master
Line OUT. With mix at 50%, the Master and Cue OUTs will be identical, allowing multiple sets of
headphones to monitor.
Mono/Stereo Effects Loop
Start with DJ Cueing or Two-Input Mixer patch. Patch Send output to effects module of your choice, such
as Erbe-Verb or Echophon. Set effects module MIX control to 100% wet, and patch its output to Mono
Return input. For Stereo effects, patch left and right outputs of stereo effects module (such as Erbe-Verb)
to L and R Return inputs on Rosie. Set effects volume with Return level control. Optional: Patching a VCA
in series will allow dynamic control of effects volume. For example, patch Send to an Optomix, take Ch1
OUTput to the Erbe-Verb Input, and use a cycling MATHS channel patched to the Optomix Control Input
to dynamically modulate the level of signal being sent to the Erbe-Verb.
Three-input mixer (2 mono channels + 1 mono/stereo channel)
Start with Two-input mixer patch, and add a third audio source to one or both of the FX Return inputs.
Set “channel 3” level with Return Level control.
Stomp Box Integration using CV Bus (no adapter cables necessary)
Set up patch of your choice. Patch Send output to Mono input on CV Bus Output stage, setting level with
the CV Bus output Level knob. Patch CV Bus ¼” output to first input on pedalboard. Patch final output of
pedalboard to CV Bus ¼” INput, and set level with CV Bus input Level knob. Patch OUT to Mono Return
Input on Rosie, and set Return amount with Return Level control.\
Ping Pong Reverb
Patch audio of your choice to either or both of the Rosie inputs. Patch SEND to Erbe-Verb IN. Set Erbe-Verb
MIX to 100% wet. Patch Erbe-Verb Left OUT to Optomix Ch1 Signal IN, and Erbe-Verb Right OUT to
Optomix Ch2 Signal IN. Set up MATHS for 281 Quadrature mode (see MATHS manual). Patch MATHS Ch1
Unity OUT to Optomix Ch1 CONTROL In, and MATHS Ch4 Unity OUT to Optomix Ch2 CONTROL In.
Patch Optomix Ch1 OUT and Ch2 OUT to M and S Return INputs on Rosie. Set Return level, MATHS and
Erbe-Verb settings to taste. Take stereo output from Rosie LINE out. (OPTIONAL: use ModDemix instead of
Optomix for different timbres.)
