Deckard's Dream Synthesizer
Hi all, this is the place to find the latest building documents for Black Corporation's Deckard's Dream polyphonic synthesizer.
Currently, this project is at rev 1.0, PCB's are currently being released to builders. (18.Oct. 2017) and are being constructed.
A new PCB version rev. 2.1 is planned and the release is planned for July 2018, this page is only for rev.2.x
Product Info:
the Deckard's Dream product is available as Build to order and DIY KIT Version, both released in 2017.
Its also known or coined as the "DDRM".
The difference in the DIY KIT and assembled (Build to order) are:
- the component format, the DIY KIT is mostly THT, the build to order synth is mostly in SMT.
- The case size is not as deep for the build to order as it is for the DIY.
Note: Although the DIY has most of the SMT devices pre-installed onto the PCBs, there are over 675 SMT decoupling capacitors (0805) and one small (SOIC8) power switch device that MUST be installed by the builder, in addition to the through hole components
A addional 1U expander is planned - release in 2018

Shared Mouser Basket: link here
Ultravox reply: "The cart doesn't include items that the BOM says are sourced from eBay, Small Bear, synthcube, etc."
About partsourcing: check the price for the next price break ( 3 resistors are more expensive than 10)
for EU users: order from www.TME.eu standard parts, its cheaper as mouser

tested/stable Firmware: (don´t install the latest firmware on important productive environment, thats why i prefer the following)
- build by DSL-man: 1.2.1 firmware with 2 soundbanks from 1.2.3 release : DD1.2.1_with_2banks.zip
If you have a working DDRM and only want to update the firmware or soundbanks, just connect a USB cable to your PC and drop the unziped file on the "storage device disk", the zip file contains a firmware file and 2 soundbanks (Bank2 are CS80 patches)
