How to back up your Alesis Quadraverb patches before it's too late

Every Alesis Quadraverb still in service is running on borrowed time. The programs you have tuned over the years live in battery-backed RAM, and the battery in a unit built between 1989 and 1991 is long past its design life. When it goes, the unit powers up with a scrambled or empty user bank and there is no undo. Backing up takes about ten minutes and costs nothing.

What you need

Step 1 — cable it in both directions

Run a cable from your interface's MIDI OUT into the Alesis Quadraverb's MIDI IN, and a second cable from the Quadraverb's MIDI OUT back into your interface's MIDI IN. This is the single most common failure: with only the outbound cable connected you can send parameter edits, but the unit's reply never reaches the computer, so the dump appears to do nothing.

Step 2 — enable SysEx on the unit

Press MIDI on the front panel and page through to the SysEx setting. It must be enabled, and the device ID should be noted; the Quadraverb responds on manufacturer ID 00 00 0E with device 02. Also make sure the unit's MIDI channel matches whatever you configure in the editor.

Step 3 — connect and request the dump

In QVERB, open MIDI Configuration, click Connect MIDI, and grant the SysEx permission the browser asks for. Then request a full bank dump. The Quadraverb answers with a single SysEx message containing all 100 programs — around 14.6 kB on the wire, which unpacks to 12,800 bytes of program data, 128 bytes per program.

If you only need one sound, you can request a single program instead: that returns a 147-byte message that unpacks to 128 bytes. The edit buffer — the sound currently being heard, including unsaved changes — is addressed as program 100.

Step 4 — save it, then save it again somewhere else

Write the dump to a .syx file with a name that says what it is, for example quadraverb-userbank-2026-08-04.syx. Then copy it off the machine — cloud storage, a second drive, an email to yourself. A backup that exists in exactly one place is not a backup.

Step 5 — verify before you trust it

Load the saved file back into the librarian and check that all 100 program names read correctly and that no slot decodes as garbage. A truncated dump usually means the inbound cable dropped mid-transfer; re-request it rather than keeping a partial file.

Restoring later

Sending the same file back is the reverse operation, and it overwrites the user bank. Restore deliberately, not casually: dump the current state first, then send the archive. If you only want one sound back, send that single program rather than the whole bank.

Do it before the display fails too

Backups get harder once the front panel stops being readable — although not impossible. If your LCD is already dim or dead, read editing a Quadraverb with a broken display. For the message formats behind all of this, see the Quadraverb SysEx reference.
