MOTM-650 4-Channel MIDI-CV converter

I've been talking about the 650 midi /cv module in many previous posts, and I am still awaiting my own to be delivered.
(have been told on wednesday that it may ship on Friday, which was yesterday so who knows, I'll have it next week?)
For those of you who haven't yet visited the SynthTech website, or not recently, here are the specs and a picture from the shipping version as of this moment, taken from the synthtech site.
Note the different pushbuttons as compared with the prototype visible in the downloadable catalog on the synthtech site.

MOTM-650 4-Channel MIDI-CV converter
$499 assembled & tested
The MOTM-650 is a 2U wide, full-featured 4-channel MIDI-CV converter. Features include:

Voice allocations settable as four 1 voice, two 2 voice, or one 4 voice group - each voice group separately addressable via MIDI
Voice assignment modes on a per voice configuration: Poly 1, Poly 1 steal, Poly 2, Poly 2 steal, Unison, Solo Unison, Solo, Solo Rotate.
Dual arpeggiators, each arpeggiator assignable to any active voice group - one arpeggiator per voice group
Arpeggiator clock sources - MIDI IN Clock, internal clock (60-238BPM weighted), or external
Arpeggiator clock divisors /4, /3, /2, /1.5, 1X, 1.5X, 2X and 4X the clock rate
Arpeggiator note order as up, down, up/down, and down/up
Arpeggiator modes are normal, ordered, ping pong, and random
Portamento - per voice group configurable as constant rate or constant time
Each voice group is independently configurable
Firmware updateable via MIDI (Windows and Mac OS 9 update utilities provided)
All MOTM-650 options settable via MIDI CCs or MIDI System Exclusive commands as well as the front panel user interface
MOTM-650 Settings and state are remembered across power cycles
Patch storage for MOTM-650 settings (up to 32) - recallable via MIDI patch change command
Microtuning per MIDI spec
Pitch bend adjustable from +/- 0 to 24 to be added to note CV on all voices
Each of 4 AUX outputs assignable to pitch bend, channel aftertouch, or any MIDI CC.
Velocity jack on each voice can be configured to be velocity or a trigger - providing a 5ms pulse when the voice is retriggered
LEDs to monitor MIDI IN activity, internal/external/MIDI clock, and voice gate operation
8X2 LCD with variable backlight and 4 buttons for the user interface
External clock in jack
Transmits MIDI clock if set to external or internal clock
The MOTM-650 packs all these features into a 2U wide module, using the latest SMT data converters, low-drift op amps and precision voltage references. Most MIDI-CV converters use 12-bit DACs: the MOTM-650 uses a true 16-bit DAC, and an octal 10-bit DAC for the Velocity/Aux outputs. No other MIDI-CV converter has as many features in a small space.

There will be an optional firmware upgrade that adds additional features such as MIDI-sync'd LFOS and the ability to chain units. This will be a low-cost (<$50) upgrade. Firmware upgrades to fix bugs are FREE OF CHARGE (none planned..heh).

NOTE: This module requires a MOTM-950 or other source of +5V, 575ma power
