Here is my current selection of patches,
Most use a GR-55 plugged into the SY-1000 return, but hold up on their own.
Others are made for a midi sound module (Roland Fantom Xr) plugged into the Return and send patch midi commands.
But all use the midi in EXP pedal cc# from the GR-55 to control the mix blend of the Return, or control SY-1000 effects.

They use the SY-1000 GK bass and preamp (bass mode).

thanks for this.  i'll load them up and experiment.

would it be correct to assume that you are using mostly the pcm sounds from the gr-55 in this configuration?  if so, are you typically running those through the sy-1000 amps (while disabling the ones from the gr-55)?


Yes I use the GR-55 for mostly PCM tones, but I don't usually run them through preamps,
only guitar/bass type tones need run through guitar/bass preamps.

Both the GR-55 and SY-1000 are setup to run "stand alone", but things sound better with both.

Very nice sounds! Thank you for this.


Thank you gumtown :)

I'm curious about the setup to run the gr55's expression pedal to drive the SY1000.
I read that you also have a DIY Y cable to control the 2 machines at the same time

I just found the GR55 and a GK3-B with the 13 pin cable at a really good price. So the question is relevant to me.

As I now have 3 good 13pin cables and one defective on a pin, I was wondering if I can solder the y myself and if the addition of voltage is not a problem for the GK3. Unless I'm mistaken, in principle the Y assembly is like a parallel assembly? the voltage stays the same and the amperage increases, right? always +7V pin12 and +7v pin13.
