Re: OMG:VFX and sysex control

Here is the .tx for filter 1 cut off, voice #1.
.tx $F0 $0F $05 $00 $00 $00 $00 $01 $00 $00 $00 $0D $00 $01 $00 $00 val4.7 val0.3 $F7
You will notice I am not using the val statements at the blue location, when I observe the sysex coming out of my synth i see that those values are always 0, so I leave them.
Your hex editor sounds good.
I would need it to edit that "voice" value and to edit the last two before the $f7.
I have been using Mark's editor for major construction. I have found that setup goes pretty quick once you get used to it. The ability of recording the sysex output from the synth is awesome.
I click the record, press the button or move slider on synth and i have a capture of the sysex string. However, I need then to edit the orange bits above in the string. When they are captured they have values like $02 in them and need to be changed to the val4.7 val0.3.
That, while was ok using Mark's editor, took a while and was very tedious.
So really, there needs to be a way to search and replace for those values on all strings.
I can envision a streamlined process coming out here.
Perhaps Mark can add in some kind of hex search and replace function to his editor?
After I finish with my mega presets, I will post something next that explains my process, which has worked pretty well for making my preset. We need some kind of tutorial about this. Perhaps I can assist with that.

The only problem here is that I have captured the sysex output, and would need to edit each string individually to put in the "vox".
So here is an example of the captured sysex string for filter cut off.
.tx $F0 $0F $05 $00 $00 $00 $00 $01 $00 $00 $00 $0D $00 $01 $00 $00 $02 $09 $F7
In my process, I go and capture all of the sysex strings using Mark's editor, then go back to replace the orange numbers with the val statements.
I need some way of search replace on the location in the string.
I do have a way to edit the red location, thankfully all the bits are the same up to that bit, so I can just highlight the whole string up to that point ie.. .tx $F0 $0F $05 $00 $00 $00 $00 $01 $00 $00 then replace with the same thing .tx $F0 $0F $05 $00 $00 $00 $00 $01 $00 $00
changing the green value for my voice change. This works.
I can't think of a way of changing the orange ones...
The one issue with Mark's editor I found is that it would not let me enter negative hex in the min max postion.... I will dig on that further tho... and when i go back and forth between yours and his, his changes the values to be decimal and postive.
I will continue and post my experience to lead others into this.
I will also try your editor below.
