I recently went to connect an Ensoniq ESQ1 to a MacBook for the purpose of getting a SysEx connection established. I was intending to do some bulk dumps, bulk loads, etc. I was using the SysEx Librarian by Snoize, and from what I have read, it is a very well-established app. What happened instead was that the ESQ1 went berserk and lost its OS stability. It would not power up except to display garbage. I read the ESQ1 manuals, checked with Ensoniq user groups, and still have no idea how a data stream intended for data storage areas (i.e., the program and patch banks) could so severely corrupt the OS. I tried all manner of resets according to the technical manuals, to no avail. I had to take it to a shop to have it re-stabilized. My question is this: how could this happen, and how can a similar action be made to go correctly? The MacBook Pro that I used is not that new, so I don't think that it was "too high powered". Of course, since the ESQ1 was made in the 1980s, I suppose that it might be necessary to insert some sort of timing delays into the SysEx request initiative. I checked about details for that possibility, and all I have found so far is a list of really inexact numbers. In other words, "try some experimenting until it works". If I take that approach, I will likely recreate the same disaster that happened before and I would have to take it back to the shop, telling the tech that I made the same mistake again, and paying another service bill. Obviously, this is not a good idea.

Anyone with good ideas about how to resolve this, I would like to read about them. Thank you for your attention.
