Issues with 4-byte Value Sysex for Negative Value Display - MIDI Designer Q&A

Issues with 4-byte Value Sysex for Negative Value Display

+1 vote
MIDI Target Manufacturer(s): TC Electronic
Hello Dan.

As You asked for:

See description of the problem in the comments section here: https://mididesigner.com/qa/7974/negative-and-positive-sysex-values-in-one-slider-solved

MD-file and a video: https://www.dropbox.com/sh/mnq1bui951213oh/AADX4kKmNLeeatJwqsHdTgRRa?dl=0

In the video I only show the problem for -8 to -9, but the slider-value will show -16 until I read -24 from the VoiceLive 3. Then the slider-value jumps from -16 to -32 etc.... (I update the values from Voicelive 3 by sending a sysex request to VoiceLive3 with Stream Byter Output Rules)

When I use the slider in MDP2, all transmitted sysex values will also be correct on VL3X. So ... READING negative sysex values from VL3X will be correct in the log, but NOT in the slider in MDP2. Somthing wrong with the sysex-calculation i MDP2?...

Nice example, thanks: first attempts to fix this failed, let's see when the team achieves success.

Hi Dan.
I just have to thank you for the very friendly and good service - and not least the prompt response. Thank you!

I have now tested Midi Designer (Beta: MD Pro 2 Next, 2.130 build 200126), and see that 4-byte values for V work properly!
MD now reads, and reproduces all SysEx values from my VoiceLive 3 Extreme (VL3x) in my MD-design. THANK YOU!!

Regarding Display Min-Max:
Today, the lower max value in MD is set to -99 and the upper max value is set to 512 (with a jump up to 999).You can se my example for the limitation for display min. in my erlier video her (0:27): https://www.dropbox.com/preview/Public/Error%20in%20MidiDesigner.MP4

I want to encourage you to expand the Display Minimum and Maximum value limit in the next MD upgrade. This will be very useful if we want to use a slider to display frequencies in an equalizer.

Suggestion:
Extend min. display to -1500 and max display to 20500 (This is what I use from the SysEx manual for my VL3x).

Be blessed.

Glad we got this solved! Thanks for the suggestion on the other issue. No changes are forthcoming, but one way to solve this is here: https://mididesigner.com/qa/1999/more-than-1000-ticks-and-display-values-needed

Thanks!
