The crOwBX is not a programmable-preset device. The host board controls define the active patch. Users are free to develop their own patch manager hardware of course, but at their own discretion.
The user must also provide for some sort of front panel and case. I provide a free .fpd file for use with Front Panel Express to make a 5U tall by 6U wide panel that can be rack mounted (using 19" rack rails), however please note you use this file at your own discretion as any errors in the production of the panel by the user are the responsiblity of the user.
The crOwBX uses a +/-19 Volt power supply as each board in the system has local voltage regulation. Therefore users will need a +/-19V supply. Crow uses a Power One HAA15-0.8-A modified for +/-19V as outlined here
Construction hints for the crOwBX will be added on the crOwBX main page over time detailing things such as jack wiring, examples of certain component mountings, and so on. Be sure to download the parts lists!
Lastly, it has to be said:
TL;DR: Don't blame me if you break something.
The Old Crow is available to assist in debugging a build, the standard "look over it" fee is a flat $25. Simple repairs will be provided gratis, while repairs involving damaged boards or components will be billed at a modest parts+labor fee. Cracked boards or boards soldered with, say, a 150W soldering gun must be replaced at the purchaser's expense.Now onto more pleasant things.
There are three types of order one can place:
1) To make a SINGLE VOICE system, order the crOwBX Single Voice Board Set (a single voice system can be expanded at a later date)
2) To make a FOUR VOICE system, order the crOwBX Four Voice Board Set
Note: order from the following third option only if repairing or expanding a vintage Oberheim OBX. Expansion of the crOwBX beyond the basic single-voice system requires one carrier board, one slot adapter per additional voice as well as the additional voice cards. Contact cs80.com if existing single-voice crOwBX expansion is desired and I will provide specific instructions.
3) For vintage OBX voice card replacement or expansion, order the crOwBX Voice Board Rev.2
Orders during the initial week of sale will be filled as quickly as possible, but there may be a day or two of extra delay as Crow can only pack things so fast.
