Now, I'm trying to do a sysex editor for an old synth.

I already managed to do this for my Roland MKS 7 and Crumar bit 99.

but with my DK 700, is a little more difficult.

I need to send: F0 7F 21 00 77 xx 00 00 0F 0F 00 00 F7
just a single time.

xx is a number that corresponds to a parameter of my synthesizer and also to a control change number entering in kyma.

and then
I need to send: F0 7F 21 00 78 xx 00 00 0F 0F yy zz F7

yy = (value of control change* 2) mod: 16
zz = (value of control change* 2) / 16

I would really like to do it with only 2 "midi event bytes" prototypes
because anyway, I can control one parameter at a time with this synth.

In the first, you would use

0xF0 0x7F 0x21 0x00 0x77 {!ControlNumber} 0x00 0x00 0x0F 0x0F 0x00 0x00 0xF7

In the second, you would use

0xF0 0x7F 0x21 0x00 0x78 {!ControlNumber} 0x00 0x00 0x0F 0x0F {(!ControlValue * 127) rounded * 2 mod: 16} {(!ControlValue * 127) rounded * 2 // 16} 0xF7

This assumes that !ControlNumber has a value between 0 and 127, and !ControlValue has a value between 0 and 1. If you want !ControlValue to have a range of 0 to 127, you would use:

0xF0 0x7F 0x21 0x00 0x78 {!ControlNumber} 0x00 0x00 0x0F 0x0F {!ControlValue rounded * 2 mod: 16} {!ControlValue rounded * 2 // 16} 0xF7

but i need to make something more controlable.

I use global map to make the maping between the incoming control change and the sysex editor.

i need something like that :

if !cc5(of channel N) move, then send 1 for 0.1 s (to trigger the first midievent) and send number xx
maybe i need to use an enveloppe or a pulse in the parameter field.
and maybe a capytalk expressions exist to analyse the movement of a parameter ?

for the second midi event i already use a delay of 0.1 s.

!cc05 hasChangedInLast: 0.1 s

now i can make my editor.

any tips to send a fixed value when a parameter move.

i think i need to do some scripting for that purpose.
but if it's to hard i can make this with a lot of midieventbytes.
