Thanks, Ian.
SIZE:
As delivered, the stop plates are h21" x w14". However there is about 3"-4" at the bottom of the plate the Microcontroller is supported that could easily be cut off if necessary to reduce the height; it also keeps the lower stop buttons clear of the key cheeks. The 20/40 stop sizes are the same height - you just reduce the lateral size by judiciously cutting off a vertical section of the plate.
The Jambs overall are about 10" wide (reduced in width by the angle of course) and their depth is up to you, but you should affixed the encoder & decoder to the inner & outer walls of the housing (indide of course).
POWER:
For the labelling, the OLEDs are driven via the USB feed to the microcontroller. You will definitely need a powered USB hub with a Mac -I use two as I have loads of USB stuff on my console. All the Windows PCs I have used have been able to drive 34 OLEDs out of the controller with no difficulty. In fact on a different design, I have driven 60 SSD1306 OLEDs.
For the switches & their LEDS, you need a 9-12v DC supply which can easily be shared between the Encoder power, the Decoder power, and the Decoder drive to the switch LEDs.
I have had these kinds of arrangements running for over a year one way or another with no issues.
EN/DE/CODERS:
In my current jambs I have used OrgautoMatech Encoders & Decoders. In a previous console I used MIDI Boutique but I cannot recall which, but the currently available mpc64up MIDI Encoder and mdec64 MIDI Decoder look as though they'd be fine.
SWITCHES:
The switches I am using and am able to obtain are quite silent - they just make a fairly quiet click when pressed (or hit!). They are micro-switch based so you can probably guess the sound.
Prices are detailed in the Construction Manual which is available in the Core Kit or separately, but I am happy to email the outline details if you drop me an email (
KAS@KASpencer.com). The manual is currently being printed in a low volume at the moment.
I hope all that helps, Iain
Best wishes,
Ken
