MOTM

Since Paul has scheduled modules that require the new +5v p.s. to ship
within the next 1/2 year, I've been considering ps setup for my system
for these modules.

On the motm news page, Paul has listed the motm 950 with pcb connector
board for 6 modules requiring +5V and 3 modules that do not require the
+5V @ 400ma.  If I remember (which may not be correct), the 'rule of
thumb' for the motm 900 @ 800ma is about 20-24 modules max.  Is it then
reasonable to assume that the 950 can safely power about 12 modules max?
Or does this depend upon the +5V to non +5V ratio of modules connected?

Are any of you thinking of alternatives to the 950?  Given my limited
front panel real estate (or maybe overindulgence in module acquisition),
I'm tending towards putting both of my current power supplies in back of
my cabinets (so a 1U 'switch' front panel would be nice).  Are any of you
thinking of doing this with a 950-like ps?  If so, how many +5V
modules and non +5V modules are you considering, and which power supply
(and associated components) are you considering?

Thanks, Jeff

The MOTM-950 can power about 12 "old" MOTM modules AND 8 500/600 series at the same time.

Is it "preferable" to run the "old" modules from their own separate power
supply, and the 500/600 series from the 950, to keep any digital "noise" on the
power lines away from the analog-only modules?  Or is this overkill?

Overkill.

I'm using 900s for the normal modules and wiring separate +5V linear 
supplies in parallel with them for the 500/600 modules. I'll be using 
the new 990 board when it ships.

I was just reading about the Alesis Air-Synth and thought that an 
air-module would make a good controller. Three CV outs (X, Y, Z) and 
three GATE outputs (also for X, Y, Z) with a configurable gate 
threshold. It would be very similar to having three MOTM-850s. The IR 
transmitter/receiver would not be mounted on the module, it would be 
plugged in just like a foot pedal so it could be positioned anywhere. 
Put the sensor on the ground and let animals sniff it to control your 
synth, or put a bunch of moths in a cage and let them control your 
synth. Or does the operator need to be warm blooded for the IR to 
sense them? Lots of possibilities. Way more fun than a joystick, IMHO.

You have to emit at least 80F (usually) for the IR to 'see you'.

Do you mean on average 15ma PER +-15V module (given the previous
guestimate of 8 +5v and 12 +-15V modules per 950)?
Jeff

Yep.
