Update via the kickstarter:

"Last week I finished updating my mechanical design and took the changes I made back into my PCB Layout software. I then updated the position of the components in the PCB layout. I managed to include a second USB host port on the SSP and made some room by rotating them 90 degrees. I also decided to move the SD card slot closer to the CPU module to facilitate the routing and shorten the distance the SD card traces have to travel (which is good for reliability).

I'm now busy updating the layout, re-routing traces, moving a few of the power supplies on the board, updating component values, etc. When I'm done with this second pass of the layout and it all looks good I'll be going through my (long) todo / checklist to see what else needs to be done or checked. If nothing major needs to be done in the layout I'll be running the DRCs (design rule checks) in my software, correcting any errors that come up, running the design by our manufacturer and preparing board files for production so we can get prototypes built. I hope to be done with the layout in 1-2 weeks. I’ve also sent over the mechanical drawings of the front panels to our CNC subcontractor to discuss the production of prototypes.

Past week, Celine continued the GUI code design work for the SSP, and made the following updates:

1) button layout at the right-hand side of the screen.

2) parameter values of the LFO and Envelope Generator module are now plotted on vertical graphs.

3) the vertical graph is also shown next to the text in large font when turning one of the encoders.

4) layout and position of the ADSR envelope

Below you can see a short video while she’s testing the GUI code on her computer (no sound). To change the parameter values she uses the Percussa Remote control surface which is connected through USB to her computer.

Thanks again for your support and until next update!

Bert & Celine"
