Archive of the former Yahoo!Groups mailing list: MOTM

JH battled the flu this week and finished his simulations for the MOTM-810 a VC
ADSR with typical MOTM over-the-top specs. Kit builders will delight at the
nearly 90 resistors, 18 transistors, 16 diodes, 15 op amps AND a blinky LED.

This is how the controls/ins/outs are set ∗currently∗, and of course open to
wide (but civil) debate. No cost yet: the parts are cheap (in fact no single
part on the pcb is over 22 cents) but the ∗labor∗ on the PH side will be
extensive. I will say this: if I get 80 modules pre-ordered (and DO NOT SEND ME
THIS NOW!) I will get them pre-inserted like the '480s. The resistors, that is.
I have ∗no idea∗ on the final cost, but it will be over $149 but less than $249.
Remember, you are paying mainly for the front panel controls (see below) and the
labor in just amassing all these parts. But when has MOTM disappointed in our
over-the-top-ness :)

2U wide

CV inputs
A, D, S and R CVs (-5V to +5V range. A positive voltage ADDS to the panel's
setting, a negative voltage subtracts the setting)
Velocity CV (set up for 0 to +5V)

Outputs

Dynamic EG Out: the VCA'd version of the positive envelope. This is not for
passing audio through, it's so that the Velocity out of the MOTM-650 can scale
the overall amplitude of the envelope.

Positive and Negative EG Out. Times are <1ms to over 24sec for A, D and R.

Gate IN

MODE switch: Normal/Burst/Cycle. In Cycle, the EG internally retriggers at the
end of the Release and re-Attacks. This happens no matter what GATE is doing, so
it's like the Serge DSG (a wacky LFO thingy). In BURST, the EG CYCLEs as long as
GATE is high, then it releases and stops.

Now, the astute folks will see a lack of input attenuators of the 4 CV ins.
Why...no fit! But I can add 2 general uncommitted attenuators that you can patch
in if you need them. Also keeps the price down, because if you want 8 pots, 9
jacks, a switch and a LED you are in the $300 module range....so be careful what
you wish for :)
