What is sysx ... ?
Please note this information is for midi equipment
[ Sysx is used to remotely control sound data. Samples require vast amounts of disk/memory space. To get around this most people use sysx commands to store whole patches or tones. Sysx can be used continuously to change sounds in real time and can be assigned to virtual sliders on your computer/seq.
Basically sysx developed from short word lengths, 5 words then to 8 words and upwards. First part represents the sysx start command F0 in Hexadecimal (base 16), the handshaking process (ack/nak).

The first word represents the manufacturers identification (ID), each manufacturer has a unique ID the example above is for ROLAND .
The second is the equipment type, in this case a Juno 106, it's called a function because more than one piece of equipment may understand the same patch data e.g. Juno106 is very similar to an Mks7, they both talk the same language.
The third word is the midi channel, each piece of equipment must have the same midi channel for both parties to 'understand' the conversation.
The forth word is the parameter, the thing or part of the sound that you wish to store or change
Associated with this is the fifth word the value of the said parameter.
The message closes with an F7 (EOX), end of message]

Where can I find sysx (Sysex) on my sequencer... ?
[
Chase sysx events will load all your sounds when you use the sequencers transport system this prevents you from getting the wrong sound, the filter can be used to capture data when demixing or splitting a song.]
Sysx editor is found under modules setup.

Why is it not working... ?
[Most sequencers and equipment using sysx have to Tx & Rx on the same midi channel.
To transfer bulk data you have to press record on your sequencer and write on the piece of equipment you are transferring from, make sure you read the manual.]

How do I control the sound via sysx... ?
[ Set your seq to record on the same midi channel as your equipment press record and then change the sliders on the equipment, a good sequencer should capture all of this.
Today there are many editors for all sorts of equipment that run independently of a sequencer but you still need a midi interface.

How can I use bulk commands... ?
[Bulk dump/load available on lots of equipment will transmit or receive all of your patches and instrument settings in one go. This is very handy as it means you don't have to transport your equipment to the studio, just take a disk. The studio has to have the same equipment of course.
