Generic Sysex Dump Recorder

Download: https://sourceforge.net/projects/ctrlr-utilities/

Record incoming Sysex messages, bulk dumps etc from MIDI device. Should work on any MIDI device. This panel can re-send Sysex back to MIDI device and save sysex to file and load sysex from file to be resent back to MIDI device. You can also insert a custom dump request command. Sysex dumps are retained in memory across sessions. Custom editing of sysex message possible.

How to run this program.

This program needs to be run from within the Ctrlr program itself. Download a copy of 5.3.201 for Windows/Linux or 5.3.198 for MacOS. and load this program into Ctrlr. This can be done from within a DAW too, by loading this panel into the VST version of Ctrlr, which will have been preinstalled into your VST folder.

[1] Go to :: File » Open Panel

VST or STANDALONE INSTANCE

It is also possible to run this program as a separate standalone executable or VST .

[1] Open this program from within the Ctrlr program
[2] Go to :: Panel » Panel Mode. Change the height of the panel to 135 (See below)
[3] Then go to File -> Export -> Export Restricted Instance.

※ Workaround/Bug Fix :: To build as standalone executable on Windows or export as VST, please add 24 pixels to the panel height before exporting. (otherwise you will find the bottom 24 pixels have been truncated).

SysEx Checksum

August 1, 2018July 31, 2018 by audiologic

I all,

I would like to find a way to get the correct value for the checksum 3e in this example

F0 50 2C 04 00 11 00 10 20 00 00 01 xx xx 00 SUM F7

the checksum is the summation between ( ) so the sum of 14 bytes before the SUM starting at 50.

xx xx are 8 bit data

F0 ( 50 2C 04 00 11 00 10 20 00 00 01 00 00 00 ) 3e F7

50 + 2C + 04 + 00 + 11 + 00 + 10 + 20 + 00 + 00 + 01 + 00 + 00 + 00 =. 3E

If I use external 8-bit checksum calculator it works perfectly but I can’t find a way in CTRLR, any idea ?

In CTRLR The Zy calculation seems not to be the right solution because I need to include the 12 bytes before the calculation and if I use y with greater value than 9 the result is always 0.

Regards
