Hi cricky

Can you give me a little more information on what it looks like when you turn left and right? It looks like we are going to need to count the 3rd and 2nd to last commands, but before I put math together I need a greater picture of the messages. Can you give me a screen shot of the log window while turning left for a few signals and then turning right for a few more?

Thanks
Jared

Its a V-synth GT synthesizer
Im using Presonus S1

The information inside the black rectangle on the image is the 512 Patch (last patch #)
The information inside the red rectangle on the image is from patch 1 - 14 (bottom to up)

Turning Left continuously ends at patch 1 and stays there
Turning Right continuously ends at patch 512 and stays there

I did that in order to show some more information as well as last patch information.

The other pic is a picture of the patch DIAL...The circle object with lines

One last question. Do you want this to look like an endless encoder just reading out left and right, or do you want this to work like an absolute controller?

Endless encoder pls

Hi cricky

Since I don't have this unit we are going to have to be flying a little blind, okay? I'll put together a solution I think will work and I'll need you to tell me if it doesn't, okay?

I'm going to assume that the second to last bit of data, before the F7, cycles down to 0 when turning right and then resets to 7F and cycles down again and again as the bits of data to its left cycle on their own. This is going to be our trigger variable. As it cycles MT is going to guess whether it is moving up or down and trigger the direction accordingly. We are going to have to deal with it cycling from 0 to 127, but we'll get there. We are going to start with it only turning right, and if that works we will create the left translator.

Code: Select all

Translator 1: Right turn
Incoming Message: F0 41 10 00 00 21 12 03 00 00 00 57 pp qq rr F7
Rules: gd=rr-ga
ga=rr
if rr==0 then Goto "Zero"
if gd>=0 then exit rules, skip Outgoing Action
Label "Zero"
if ga!=127 then Exit rules, skip outgoing action
Outgoing action: B0 30 41

Let me know if that works. Keep in mind it is just when turning right.

Thanks
Jared
