Output Assign Options To clarify the signal path of the JV/XP synths, a simple case can still well illustrate the principle options involved. Output Assign settings are available in several memory locations which can interact based on destinations between EFX, MIX, OUT1, OUT2, and PAT depending on the specific location. The beginning of a sound's signal patch starts with the Tone component of a Patch. Further interaction between upto 4 Tones in a Patch can take place and be moreso affected by the STRUCTURE(s) used by the Patch. In Patch Mode, those components are all that need to be considered. However, a further complexity in avaialble in Performance Mode between the Performance Source and its EFX Type. Let's start with listing the pertinent sysex memory map locations involved. Table/Offset Parameter Name Data Values ============ ============== ==== ====== 1-2-1/00 1A EFX:Output assign 0-2 MIX,OUTPUT1,OUTPUT2 1-2-1/00 27 Chorus:Output assign 0-2 MIX,REVERB,MIX+REV 1-2-2/00 0A Output assign 0-4 MIX,EFX,OUTPUT1,OUTPUT2,PATCH 1-3-1/00 19 EFX:Output assign 0-2 MIX,OUTPUT1,OUTPUT2 1-3-1/00 26 Chorus:Output assign 0-2 MIX,REVERB,MIX+REV 1-3-2/00 7D Output assign 0-3 MIX,EFX,OUTPUT1,OUTPUT2 1-4-2/00 36 Output assign 0-3 MIX,EFX,OUTPUT1,OUTPUT2 In the "JV-1080's Owner's Manual" on page 100, a "JV-1080 Effect Routing" drawing illustrates the many signal paths possible from each Tone via its four paths: left and right channel output levels, and chorus and reverb send levels. From there the complete matrix of signal options with the EFX, Chorus and Reverb chips are shown. On pages 81-82, 10 general effect routings for patches are illustrated with their appropriate OUTPUT, PATCH EFX OUT, PATCH CHORUS, and PATCH REVERB settings. Although they illustrate their application to Patch Mode, their are just as descriptive in being applied to Performance PARTS. Since Patch Mode is the easiest to understand, I will concentrate on Performance Mode's application of Effects Routings. When the Performance Effects Source is set to PERFORM, the parameters for its EFX settings are used by all Parts with Output Assign's made to EFX. All Output/Send Levels act as MASTER values to which MIDI volume/expression/reverb/chorus controller values on a Part act as "submixers". Note that expression (CC11) use for volume is determined by a SYSTEM setting (VOL or VOL+EXP) for volume source. The Reverb and Chorus controllers are CC91 and CC93 respectively. The parameters for ALL three available Effect chips (EFX, Reverb and Chorus) are controlled by those of the current TEMP Performance EFX settings. Only their relative level "submixes" may be changed by each Part. If a Part's Output Assign is set to PAT and its assigned Patch's Tone's EFX Type is the SAME as the Performance EFX Type, then the "best" Patch Mode like "equivalence" is available for that Part's Patch, including all of the Patch's orignal tone level settings with THOSE Performance Source PERFORM settings. However, to FULLY take advantage of Patch "equavalence" to its character as in Patch Mode, the Performance Source must be set to the Part of which the Patch is assigned, allowing its EFX parameters to be used by the Performance AND its tone level settings when the Patch's Output Assign is set to PAT. Remember that all Patch EFX parameters are ignored in Performance Mode when the PERFORM Source is PERFORM. Only when the Performance Source is set to a PART which has a Patch assigned which you specifically want to FULLY emulate, INCLUDING its Reverb and Chorus type AND settings, will real "equivalence" be attained. In saying the above, most of the ROM Preset Patches were designed with EFX Type 1 most likely to minimize the "equivalence" problem noted. Examples of Performance Presets which take advantage of the Output Assign PAT setting for Parts in various ways are: Preset EFX Type Source PR-A: 03 11 pt1 PR-A: 05 15 pt1 PR-A: 07 4 pt1 PR-A: 09 7 PERFORM PR-A: 14 12 pt1 PR-A: 15 24 pt1 PR-A: 23 1 PERFORM Benjamin Tubb brtubb@cybertron.com http://www.cybertron.com/~brtubb
