Firmware

200e ELECTRIC MUSIC BOX
Occasionally, we make changes in a module’s firmware to fix software bugs or to add new features. The little firmware cards we used to supply with modules have been replaced by a single USB card. With a Macintosh computer running OS10.5 or higher, you can load the USB card from the web, and then transfer the firmware to the module.

There are now two versions of the firmware for each module. The old version numbers are between 1 and 29; the new versions are numbered 30 or more. All current modules are shipped with version 30 firmware.

ALL MODULES IN A SYSTEM MUST BE ONE VERSION OR THE OTHER – A MIX CAN RESULT IN IMPROPER OPERATION.

First you’ll need to equip your computer with the smarts to read the USB card. Just click on the “Buchla Firmware Utility” link below to download the appropriate program.

To download a module’s firmware to your computer, click on the relavent firmware link in the table below.

To program the firmware hex file into the USB card, plug the card into your computer and double-click the hex file’s icon in the Finder. The Firmware Utility application will launch and display info about the programming process.

Now plug the USB card into the memory card receptacle on your system and power up the system while holding the Remote Enable button on the target module. The LED on the card will blink rapidly while the firmware is being loaded to the module, then blink slowly when the load is complete. Some modules use alternatives to the Remote Enable button; see the exception list at the end of the next section.

NOTE: these instructions apply only to new systems (delivered after Dec 1, 2011) with all modules running version 30 (or higher) firmware.

DO NOT OPERATE SYSTEMS THAT MIX VERSION 30 FIRMWARE WITH PRE-VERSION 30 FIRMWARE.
(They won’t burst into flame, but they probably won’t operate correctly).

We recommend that when you add new modules to an older system you update all the modules to version 30 firmware.

200e-USBFirmware Utility1.6710/29/2015BuchlaFirmwareUtility167.zipOccasionally, we make changes in a module’s firmware to fix software bugs or to add new features. The little firmware cards we used to supply with modules have been replaced by the USB Utility Card. With a Macintosh computer running OS10.5 or higher, you can load new firmware to the USB card, and then transfer the firmware to the module.
Additionally you can change the USB Utility Card to function as a bi-directional MIDI interface for a 200e system. MIDI channels 1-4 will be sent to the internal 200e MIDI busses A-D respectively and MIDI beat clock can also be sent to the bus system, or output by the 252e. The 218 can also be used to output MIDI note and velocity data.
