Concepts The   Patch   Editor   has   been   designed   for   easy   parameter   editing   for   many   of   the   older   keyboards   with   easy   to   use   controls   for   every   synth   type.   Every   active control   will   light   up   to   make   fast   changes   simple   and   buttons   are   colour   coded   depending   which   state   is   active.   Each   control   that   is   changed   will   clearly   identify itself on the display. There   was   a   stage   when   most   of   the   keyboards   manufactures   went   though   a   process   of   removing   all   the   knobs   and   replacing   them   with   a   parameter   driven system. Anyone   who   has   used   one   will   know   how   difficult   it   is   to   use,   especially   live.   When   the   complaints   started   arriving   some   started   making   plug   in   patch editors.   The   problem   with   these   is   they   only   worked   on   one   type   of   keyboard   and   were   (and   still   are)   expensive   and   rare.   The   'Patch   Editor'   can   be   used   in place   of   a   PG-300   or   MPG-80   as   well   as   handle   midi   control   of   midi   and   sysex   capable   keyboards.   It   includes   an   internet   update   system   for   software   changes or   new   keyboards   support,   and   includes   an   external   input   that   can   be   mapped   to   any   continuous   control   and   all   the   active   controls   light   up   to   make   it   easy   to use. Each control in each synth is kept in lookup tables. This approach has made the Patch Editor very versatile and flexible. Some of the features are: Can   translate   midiCC   to   the   currently   selected   patch. This   will   allow   any   synth   to   be   controlled   via   midiCC   for   software   that   does   not   support   sysex.   One midiCC command for filter cutoff adjust, for instance, will output the correct codes for filter cutoff adjust for any selected synth. Can   control   both   the   Upper   &   Lower   Tone   boards   in   the   MKS-70   &   MKS-80   from   the   Patch   Editor   directly   separately   or   combined.   Note,   the   MKS-70 needs the latest system ROM (v1.08). Every   control   identifies   itself   and   it's   value   on   the   display   in   real   time.   This   is   important   when   unused   controls   are   reassigned   as   is   done   in   some   synth types. Colours change as controls are moved and each page uses it’s own colour for easy page identification. Each synth type has a separate synth midi channel which is remembered. The Patch Editor also has a midi channel for it's own midiCC control. All switch positions are remembered for each synth type. The   ext   input   allows   control   of   any   one   variable   parameter   from   an   external   voltage   source.   For   example   a   foot   pedal   could   be   used   to   control   the   filter cut off much like a waa waa pedal might. The control lights can be dimmed to suit current light levels. Top   quality   components   have   been   used   throughout.   This   has   added   to   the   price   but   you   get   something   that   will   work   well   when   it   is   supposed   to   and will last. Power supply required is 12vDC with a minimum of 1Amp and the Patch Editor has reverse polarity protection built in. The plug required for power connection is a DC style 2.5mm ID, 5.5mm OD and 10-14mm shaft length with positive on the inside.
