MOTM

Ahh, I love to talk sequencers! It's been awhile since we had a good 
discussion. Larry, I'll address your questions "sequentially" ha ha!

>>>
Mode 1:  One CV knob for each CV in each step and one knob does not 
effect the other.  If you return one of the CV knobs feeding one 
oscillator during the run time, the other oscillators do not change.
<<<

Assuming you mean "turn one of the CV knobs" - yes, this is the 
normal mode of operation for all step sequencers. Each knob is 
isolated from the others.

>>>>
Mode 2:  One CV knob is a master and the others are slaves.  So knob 
1, effects the output of all CVs at that step and the other knobs, 2, 
(and possibly) 3, 4  effect the tunes relationships between 
oscillators.  Maybe mode 2 would not be useful.  But, it seems with 
stacking oscillators, it might be easier to change patterns on the 
fly with multiple oscillators.
>>>>

Typically, you would not build this into a single sequencer as a 
mode, but would accomplish this externally. One way, is to patch a 
JLH-831 or 822 to the VCOs in addition to the sequencer, and 
transpose them manually. A second way, is to transpose the first 
sequence using a second sequencer.

>>>
# of steps:
I'm not sure 8 is right,  Can a sequencer be flexible enough to 
recycle or quit at any point along the chain?  How about 12 or 10 or 
7 ??
<<<

Yes. Typically this is done one of three ways: a LENGTH rotary switch 
that selects the last step before resetting; a toggle switch on each 
stage that denotes the last step before resetting; or separate SET 
and POS gate jacks for each stage that allow patchable sequence reset 
points. With this final option, you do not always have to reset to 
step 1. Also, you could patch a MOTM-700 switch or two into the path 
and have VC of sequence vectoring.

>>>
Quantizing:
I assume this would be essential.  Is this a feature one would expect 
inside the sequencer or as another external module?  I assume if 
internal, you would want to be able to switch it on and off as some 
voltages (maybe controlling other things from oscillators) you would 
not want to be quantized.
<<<

Often included built in, as in the ModCan, or can be an external 
module that can quantize other CVs as a general purpose module. I 
have done a dead-on "Baba O'Reilly sequence using two UEGs mixed 
together, and run through the Wiard MiniWave acting as a quantizer.

>>>
Timing:
I would think you would want to be able to use an internal or external
clock.  But, if using an internal clock, would the "time" of each 
step be a quantity fixed as one division of the total sequence?  Or 
would the time of each sequence be adjustable (like on Tony K's UEG?  
It seems to me that a 12 step pattern where each step got 1/12 of the 
time might be OK for some things and not for others.
<<<

What is usual, is to have the clock (either internal or external) 
voltage controlled, then patch one of the rows to control the clock 
frequency. +1V = double speed, -1V = half speed.

If you already have a UEG, play with it in sequencer mode!

Note that I have limited my discussion entirely to the step sequencer 
genre. Pattern sequencers are a whole 'nother beast.

Moe, sequentially obsessed.
