∗ Processor is an ARM 32-bit Atmel AT91SAM7S64, running around 48Mhz. 64K
Flash, 16K RAM. In comparison, the MOTM-650 uses an 8-bit 8051 type with 32K
Flash, 1K RAM and runs at 2Mhz.
∗ 6 24-detent rotary encoders (ALPS EC12E2420801, available from Mouser)
∗ 1ea Crystalfontz CFAH2004A-YTI-JP LCD, reverse, 4 lines x 20char
∗ the knobs are custom Rogan double-shot "soft touch" with white endcaps,
~0.75 diameter. The ALPS encoders have a 'D' shaft.
∗ 1ea USB 'B' type jack (runs low speed USB 1.1). If the CGX needs a
firmware update, there is a jumper setting on the rear pc board, and new
code can be flashed in.
∗ 3ea NKK JF15 series tact switches, ENTER (blue) and PG UP/PG DWN (grey or
green, have not decided). These are larger than the MOTM-650 NKK switches.
They are ~ 0.68" square and have a nice 'click' to them.
∗ 5 Expansion jacks, comprising:
SAW OUT
TRI OUT
CHAOS CV OUT - user defined DC voltage that is 'mapped' to one particular
ChaosEngine element. So it's a wiggley voltage :)
PATCH SEL IN - when a jack is inserted, a negative voltage reduces the
current patch # and a positive voltage increases the current patch #. -5V
will be mapped to Patch #1, and +5V will be Patch #16 and intermediate
voltages mapped accordingly.
AUX CV IN - a user defined CV input that can modulate a CG parameter, ie it
has the same effect as 'turning the encoder knob' of that parameter. Mapped
to -5V is minimum, +5V maximum, intermediate voltages mapped accordingly.
3U wide module.
