CG/CGX/M650

2008-03-26 by Paul Schreiber

a) I will have all the parts in for the next run of MOTM-650s shortly and 
will have the pc boards 'run' through stuffing by early May. I will then 
ship the remaining backlog (about 6 units) and put more into the cart for 
purchase. This is not a high priority right now.

b) I added a (blurry) shot of the CG panel (and here are the audio demos, 
too) to:

www.synthtech.com/m520

Briefly, the CG is a digital/analog hybrid module that has 16 VCOs. The VCOs 
share a common 1V/Oct input. You can detune the VCOs relative to each other 
(the SPREAD) over a NARROW/WIDE range. In addition, the VCOs can be 
internall/externally modulated. Internally, there is a random modultion 
source (CHAOS) whish is a group of bandpass filtered noise generators.

As a group, the VCOs can output 4 waveforms (all 16 output the *same* 
waveform): sine and pulse (on the CG) and saw and triangle (on the CGX). PWM 
input is provided. This is a 2U wide module.

The CGX is the programmer for the CG (and also allows the 2 additional VCO 
outputs). The CGX has a 4line x 20char LCD display and 6 rotary encoders. 
There are ~ 46 CG 'parameters' that can be programmed to adjust the behavour 
of the CG (how the CHAOS acts, how the VCOs detune, etc). The CGX has 16 
presets slots you can over-write (it will ship with 4 examples, the other 12 
are copies of the factory default). There is a USB port for allowing patch 
dumping/saving when that software is available. This is a 3U wide module.

Both modules will REQUIRE the MOTM-950 or equivalent power supply (6pin 
header, needs +5V).

One CGX can connect to 1 CG via short ribbon, the 2 units need to be 
adjacent to each other in the cabinet (have not done the work to see which 
is on the left).

Wouldn't it make more sense to put saw on the module and pulse on the  
expander, since "supersaw" is so popular these days?

I also thought that the Cloud Generator used DCOs. Has this changed  
recently?

The first design (now scrapped) used a different technique for the 
oscillators, and saw was not even possible. I have the panels already :)

They are digital VCOs :)

I thought the same thing when I read it.  Also, as pulse outputs only 
alternate between two voltages, it is much easier to generate complex 
pulses using other gear.

Do you happen to know how much power these two guys will consume together?
I'm debating the possibility of building a small fancy cabinet just for them and a few other control modules/VCAs and a filter or two...

Thanks for the update. The 520 sounds interesting. I'll have to mull that one over - I am however very excited about the VC Divider, the 101's replacement module (the 102), and the Quantizer that was discussed several months ago.
 
As for the 650, when do you anticipate that the software update will be released? I'm anxious to get those bugs worked out.

one over - I am however very excited about the VC Divider, the 101's 
replacement module (the 102), and the Quantizer that was discussed several 
months ago.

I am buying parts for the 730 VC Divider this week, working on the CAD 
drawing for the front panel. I had to change vendors on the LED display, and 
moving some parts around for a mechanical fit.

As for the 650, when do you anticipate that the software update will be 
released? I'm anxious to get those bugs worked out.

I have not heard a date for that, not for a while at least. The main bug is 
using external clock on an arpeggiator that is a multiple of that clock. 
Internal clock and MIDI clock are OK.

I lent out my 650 about a year ago, so I haven't been able to work on the
firmware.  I've been waiting for Paul to produce more.  Paul's been waiting
on me to update the firmware.  Catch-22.

The good news is, I just found out the musician who borrowed my 650 doesn't
need it for awhile, so I should be getting it back soon.  When I have an
update ready, I'll let everyone know.

Excellent news! 

Please don't forget to address the bug that throws the Assert Errors that occur when you send cc's to aux1 :) 
I have a detailed description of the problem if you need it.
