Mojo Dual Manual "old models" - Support, firmware, hardware, repair, spare parts.
The Crumar Dual Manual organ "old" model was a specific organ manufactured from 2013 until May 2018. There was another Mojo Organ manufactured by another company in a limited run of 50 pieces in 2012: these are completely different. Starting from May 2018 that instrument received an hardware update, so important that we changed the name of the product to "Mojo XT".
PLEASE NOTE: THE OFFICIAL SUPPORT FOR THE "OLD" MOJO ORGAN ENDED IN 2023. THIS MEANS THAT ALSO DISTRIBUTORS AND OFFICIAL REPAIR CENTERS CAN'T SOURCE SPARE PARTS FROM US ANYMORE. IF YOU HAVE A PROBLEM WITH ONE OF THESE INSTRUMENTS, YOU CAN REFER TO ANY REPAIR CENTER SKILLED WITH ELECTRONICI REPAIR (NOT JUST PCB BOARD SWAP). FIRMWARES AND SOFTWARES FOR THIS INSTRUMENT ARE NOT AVAILABLE ANYMORE.
The focus of this article covers the firmware, software and support of these two instruments. The architecture of those instrument was quite simple even if it requires attention: they didn't have only a firmware, they used to have 2 separate digital codes, one is called "firmware", the other one is called "software". The firmware is a small piece of software resident inside one microprocessor controlling the behaviour of the panel of the instrument and the 2 keyboards, the software was the "sound engine" of the instrument. While to load the first one it was necessary to send Midi data to the instrument, the second one was similar to a normal and standard computer software and to upload this one a USB key was needed. Firmware and software works together and they need to "match".
While Mojo XT never received any software and firmware update because it wasn't necessary, the Mojo Dual Manual "old model" received dozens of updates during the long production life. What it's really important to understand, it that, at one point in 2015 we released a firmware called 6.1, a simplified version that was more user friendly. Starting from 2016 this firmware was the only one officially supported by us and we have stopped supporting older firmwares, for example 2.5. It was still possible to ask us a copy of it, but we no longer provided and we still do not provide support neither in the use nor in the installation of the old firmwares. You are completely alone if you want to perform these operations, if you make mistakes or if you don't know how to do something.
Also please note that, if something is going wrong in this procedure, now we can't help you anymore because the support for this product ended in 2023.
There's a link here to a document explaining the difference between simplified firmware 6.1 and firmware 2.5 and also a table showing the edit functions of the old and unsupported firmware 2.5.
Mojo Dual and MojoXT don't support wired editor or wifi editor (features available for the new generation instruments). Sound editing of these instruments were possible with Mojoeditor (hardware device no more in production since 2019) or via the direct connection of a VGA monitor and a mouse to the computer connections on the back of the instruments.
