Hi, Yes, I'm always sending a stereo bus to the house PA. The reason is that I work the master output quite extensively as an important part of my performance. Below is the signal path in my looping laptop and it should explain this well, I hope. 1. Inputs. Three audio inputs for three different acoustic instruments and one MIDI input for a MIDI intstrument (Akai EWI4000s). 2. All audio inputs go through a first EQ stage that makes the signal sharper and less bassy. Gives a distinct and clear shape to the signal. 3. 20 alternative effect patch chains (15 for audio and 5 soft synths). I only play through one patch at a time and as I chose one certain patch by a foot pedal, the other 19 patches are muted (except for reverb tail preservation that may sometimes keep one patch open while I'm moving into playing through another one) and offloaded the CPU. All these patches are carefully designed according to "reverse mix engineering", meaning that one certain patch may not sound "full" but when layered together into loops these treatments will make the layers sound good together as a summed mix (by minimizing clashing frequencies). Regarding the soft synths, that are played through MIDI, this sound design is already taken care of within each synth sound. 4. The software looper. Sound is being layered into loops here to create music. 5. The summed Looper output is going through a steep cut off filter that doesn't pass anything under 60 Hz. Such low frequencies would destroy the dynamics of the next stage... 6. Master compressor. This compressor is balancing the summed looper master output versus the live instrument playing input. The live input also goes directly here, bypassing the looper, as the looper is set to all wet and no dry signal. This last stage is what I mean by saying that "I work the master output while playing", since the balance is set up in a precise way that makes it possible for me to "juggle" the looper output with my live input playing. This compression also makes reverb grow nicely between recorded sounds and drop down in level to make room in the mix for those recorded sound as they appear from the loops. A "one night live engineer" wouldn't have a fair chance to create this sound; which is the sound I like and want to perform with. -- Greetings from Sweden Per Boysen www.boysen.se (Swedish) www.looproom.com (international) www.stockholm-athens.com
